Evergreen Plastics Ltd., Clyde, Ohio, began operations as the plastics recycling division of Polychem LLC, Mentor, Ohio, in 1998. Polychem is one of the world’s largest producers of plastic strapping. The company started Evergreen to develop a raw material source for its polyethylene terephthalate (PET) strapping.
Greg Johnson, vice president of operations at Evergreen Plastics, says Polychem and Evergreen are vertically integrated. Evergreen recycles curbside-collected PET—primarily soft drink and water bottles—to produce recycled PET (rPET) flakes and pellets. Polychem uses recycled plastic from Evergreen to produce strapping, which is made of 100-percent- recycled materials.
“We buy postconsumer baled bottles. We sort, grind and wash them, and then we use the material—the ground flake—to produce the strapping,” Johnson says.
Since Evergreen was established, it has tripled in size. Johnson says the company started with 35 employees and a 75,000-square-foot facility in 1998. Today, it has about 200 employees and a 240,000-square-foot facility.
Evergreen installed its first PET strapping line in 1999 and expanded its PET strapping capacity in 2005. Johnson says Evergreen primarily uses blue and green PET bottles to produce strapping. “For many recyclers, that’s not a primary stream of material. For us, that’s very much our primary stream.”
In addition to blue and green bottles, Evergreen also processes clear PET bottles. Some of the recycled clear bottles are used to produce strapping, and some are used to produce food-grade rPET pellets or flakes. Johnson says the company uses equipment that has a nonobjection letter from the U.S. Food and Drug Administration (FDA) that allows Evergreen to sell its rPET for use in food-grade applications. The company uses two Erema systems—a Vacurema Advanced extrusion system it installed in 2004 and a Vacurema Prime extrusion system it installed in 2011—to create food-grade pellets.
Equipment: A Vacurema Advanced extrusion system equipped with a Laserfilter from Erema, Austria, as well as a Vacurema Prime extrusion system from Erema
Services: Toll washing, toll flake processing, toll pelletizing, blending, compounding, toll grinding, polypropylene reclaim, high-density polyethylene (HDPE) reclaim and brokerage services for HDPE and postindustrial polyethylene terephthalate
According to Erema, which is based in Austria, all of its Vacurema systems—Basic, Advanced and Prime—decontaminate PET.
“We partnered with Erema from the beginning and stuck with them,” he adds. “There are other equipment manufacturers, but we believe Erema has some of the best technology out there because of the quality of the equipment and the quality product that it produces.”
Evergreen’s ownership changed when Sterling Group, a private equity company headquartered in Houston, acquired Polychem last March. However, Johnson says operations have remained the same.
He adds that the biggest change is that Sterling Group has been encouraging Evergreen and Polychem to grow. Johnson says growth has been a focus at Evergreen with the increasing number of sustainability commitments being made by major consumer brand companies.
“The growth we’re recognizing has more to do with sustainability initiatives and the push around plastics recycling and recycled content within products that contain PET,” he says. “What’s driving that growth is the brand sustainability initiatives. That’s still in the infancy stages, but it’s starting to ramp up.”
Michael J. Sandoval, a sales and procurement manager at Evergreen Plastics, spoke on a panel discussion during Recycling Today Events’ 2019 Paper & Plastics Recycling Conference, which took place in October in Chicago. In the session “Hungry for More Plastics,” he reported on sustainability commitments that offer optimism for recyclers like Evergreen.
For instance, Coca-Cola Co., Atlanta, reported plans in 2018 to create packaging that contains at least 50 percent recycled material by 2030. In October 2018, PepsiCo. Inc., Purchase, New York, announced its goal to use 25 percent recycled content in its plastic packaging by 2025. Nestlé Waters North America, Stamford, Connecticut, announced plans to increase recycled content in its PET water bottles in the U.S. to 50 percent by 2025.
Evergreen Plastics, Clyde, Ohio, added a Laserfilter from Erema to its Vacurema Advanced extrusion and decontamination system to improve its operational efficiencies. Austria-based Erema offers two filter models for producers and recyclers: the Erema SW RTF and the Erema Laserfilter. Both models are available in a wide range of sizes, versions and capacity options.
The Erema SW RTF serves as a partial surface backflushing system. The filtration technology works to clean a small surface area of the filter screen by directing a flow of clean melt from the back of the screen. The system can help recyclers to manage surges in contamination and improve homogenization, Erema says.
The Erema Laserfilter is a high-performance filtration system. The scraper technology is designed to enable the highest possible throughput while maintaining good melt quality, according to the manufacturer. The tool specializes in high melt rates, film-grade pellets and tasks that cannot be solved using conventional melt filters.
The Laserfilter features a rotating scraper rather than a rotating screen, which helps ensure the system is leak-free, Erema says. The static screen is sealed and prevents filtered contaminants from getting into the melted plastic. It also features ultrafine boreholes, which are laser cut into the hardened special steel of the screen discs. A self-cleaning effect is achieved through the conical shape of the holes, the company adds.
“Brands are committing to using more recycled content in their packaging,” Sandoval said at the conference. “This has potential—this is going to force us to recycle more. Evergreen is willing to do its part.”
Although Sandoval said there is concern that recycling rates are too low to meet some of these brands’ 2025 and 2030 sustainability commitments, he added, “Where there’s demand, supply will follow.”
Johnson says Evergreen is hopeful about these commitments and wants to be able to grow its business by helping to meet these new goals. He says the company is well-positioned to do that as it’s been operating as a closed-loop business for two decades. “Being closed loop is something we’ve done since day one,” he says. “We buy strap, we process strap and we turn it right back into strap. We take bottles and turn them into raw materials so they can make more bottles. That’s been our business plan for more than 20 years.”
Regarding recycled-content commitments from brands, “This is an opportunity for us,” Sandoval said during the Paper & Plastics Recycling Conference session. “We’re going to improve our current systems and maximize our throughput. We’re investigating new equipment and additional pellet capacity. There is more future demand, so for us, we need to increase our capacity as well.”
As Evergreen Plastics expands its pellet production capacity, it also is considering adding new equipment. Evergreen certainly has the space to grow at its site in Clyde. Johnson says the site is about 37.5 acres, and the company still has about 21 acres it can develop.
While Johnson can’t share what equipment the company is looking to add in the future, Evergreen has made some improvements to equipment in recent years. In the spring of 2018, Evergreen added an Erema Laserfilter to its Vacurema Advanced System. Johnson says the Laserfilter produces a more consistent product than traditional backflushing filtration equipment. He adds that the machine’s extruder has been running more smoothly since the addition of the Laserfilter.
“We were looking for more consistent extruder performance, less variation in pressures and other parameters on the line while it’s running,” Johnson says. “The older backflushing technology created some of those inconsistencies. [The Laserfilter] is a more continuous melt filter that allows you to run higher levels of contamination and still achieve better, more consistent running parameters.”
Johnson says Evergreen benefits from its involvement in industry associations, including the Association of Plastic Recyclers (APR)—he is a member of the APR PET Technical Committee—and NAPCOR (National Association for PET Container Resources). “Both groups are great resources for keeping up with industry news,” he says. “Having that voice is helpful. They do a great job taking feedback from us and working with brands to make improvements.”
Through modern equipment and knowledge gained from industry involvement, Evergreen plans to grow its ability to meet new rPET demands.
JW Aluminum Co., Goose Creek, South Carolina, first announced the $250 million Phase I of a two-part expansion plan for its Goose Creek/Mount Holly operations in 2018. Phase II of the project will bring the company’s total investment to more than $300 million.
JW Aluminum says the project also represents the fourth largest economic development announcement in South Carolina. JW Aluminum says its expansion is the second largest in Berkeley County (Google made the largest expansion in the county) and it adds 50 new jobs to the area.
Phase I will replace the existing melting and casting capacity at the South Carolina mill, while Phase II will add new mills, annealing furnaces and other processes that will allow JW Aluminum to realize the full capabilities of the caster, says, CEO Lee McCarter, as well as further expand the company’s production. He adds that JW Aluminum expects Phase II of the expansion to come online in 2022.
As of the close of 2019, the Phase I expansion was well underway. According to the company, it represents the most significant capital investment in domestic continuous cast technologies and capabilities since 1998, making JW Aluminum’s Goose Creek plant one of the most technologically advanced continuous cast facilities in the world. The expansion also will enable the company to increase the amount of scrap used in production from 65 percent to 100 percent.
South Carolina’s Berkeley County is home to the company’s corporate offices, which are in Daniel Island, and its largest sheet mill, which serves building and construction customers. The mill primarily produces 3000-series and 1000-series aluminum alloys.
Phase I includes construction of a new 220,000-square-foot building—the size of nearly four football fields—and installation of equipment that will result in 50 million pounds of new capacity. Following completion of Phase II, JW Aluminum will increase its production capacity by 175 million pounds in total.
The company was founded in 1980 as a division of Jim Walter Homes Inc., which made prefabricated homes and aluminum siding. “It was a backward integration play for them into an aluminum source for the siding of homes,” McCarter says.
Today, JW Aluminum manufactures flat-rolled aluminum products, including sheet products for the building and construction markets, fin stock used by the heating and air-conditioning industry, light-gauge converter foil for the flexible packaging industry, honeycomb foil for the aerospace industry and other sheet and foil products.
Over the years, JW Aluminum has expanded through acquisition, purchasing plants in Russellville, Arkansas, and in St. Louis from Alcoa in 2004 and a mill in Williamsport, Pennsylvania, in 2007.
The Russellville mill serves customers in the consumer durables and general distribution markets, focusing on 1000-series and 7072 alloys. Its St. Louis facility produces foil products, including gauges as low as 0.000275 inches, and serves customers in the container and packaging and general distribution markets. Its focus is on 1000- and 8000-series alloys. The Williamsport mill specializes in rolling foil products for the aerospace, containers and packaging and general distribution industries. It produces 1000-, 3000-, 5000- and 8000-series alloys.
“JW is in a unique position compared to, say, Aleris in that we cover the gamut of gauges out in the marketplace from thicker products for building and construction to thinner products for packaging,” McCarter says.
Its Goose Creek/Mount Holly mill is the largest of JW Aluminum’s operations, producing some 230-to-240 million pounds annually, depending on the product mix, he says. The other facilities produce roughly 120 million pounds annually, for a companywide yearly production capacity of 360 million pounds.
After weathering the Great Recession, JW Aluminum embarked on a project in 2010 to standardize operations across its four mills, McCarter says. This project, which took roughly five years to complete, involved developing consistent business processes and sourcing and marketing strategies.
“At the end of 2010, we changed ownership, and those new owners invested a considerable amount of money into JW Aluminum, and we furthered our efforts around people, processes and how we deliver value to the marketplace safely,” McCarter says. “It’s something we call WIN.
“The investment we are making now for vastly upgraded technology and the capabilities of the company, it’s going to make us more scrap-based,” he continues. “That facility is predominantly scrap-based today and will be fully scrap-based tomorrow with our new investment.”
JW will have the latest melting and casting technology available as a result of the expansion. The site will employ environmentally efficient melting and recycling technology from U.K.-based Mechatherm International Ltd., the Hazelett Twin-belt Continuous Casting Process from Colchester, Vermont-based Hazelett Corp. and a hot tandem mill from Mino SpA of Alessandria, Italy.
Many aluminum mills use a multistep process to melt scrap today, McCarter says, that includes preprocessing or pretreatment in a rotary furnace, for example. “We are putting in a technology that is very efficient and allows us to consolidate those steps so there will be no pretreatment of our product. In the furnace, when we burn our scrap, it will burn off the impurities, preheat the material and then dump it in the bath, if you will, that will ultimately be cast through the caster.”
After the operator loads the scrap bin, an automated guided vehicle will pick up the bin and transport it to the furnace. “From the time the operator loads the bin to the time it comes off of the first pass out of the mill—about 225 feet—it will not be touched by a person,” McCarter says.
He adds that he expects the technology to improve safety at the mill as well as expand the careers of JW Aluminum teammates because it will take them out of the hottest part of the process.
Additionally, the consolidated casting process “will vastly improve the throughput and the quality of the product that is being produced,” he says.
The company’s thin-gauge plants do not consume scrap, though its St. Louis plant does use some of its internally generated scrap.
“Our Russellville, Arkansas, facility, which is HVAC, is partially scrap-based,” McCarter says. “But it’s a higher purity alloy that is in that particular market.”
Beginning in 2010, JW Aluminum Co., Goose Creek, South Carolina, started a cultural journey to invest in its employees and processes, establishing a corporate culture that it refers to as WIN, company CEO Lee McCarter says.
According to the company’s website, “The WIN philosophy is based on the principles of organizational change. In today’s business environment, change is constant, so it’s ingrained in our culture to provide our team with the skills they need to thrive in the midst of change.
“We strive to create a culture of ownership within every department through every step of our processes. That sense of ownership drives every JW Aluminum teammate to put our customers first, take pride in the product we provide to our customers and service customers the way they deserve.”
McCarter says JW Aluminum’s WIN culture “actively engages our teammates each and every day on the ground floor of the company.”
He says JW’s Goose Creek/Mount Holly facility plans to use 300 million pounds of aluminum scrap in 2020. “That is inclusive of what will be fed into the startup of our new equipment.”
The aluminum scrap grades JW commonly consumes in South Carolina include painted siding, mixed low-copper clips (MLC), 3004, 3003 and 1100 alloys.
“We will only produce one alloy going forward: 3105,” McCarter says of the Goose Creek mill. “We are going to be the best 3105 domestic producer that there is” using the highest level of scrap.
The new melting technology from Mechatherm will allow JW Aluminum to use a wider range of its traditional scrap grades as well as used beverage cans (UBCs). McCarter says the company will blend its incoming scrap “to our chemistry in the most economical way.”
He adds, “Because of the environmental controls and the melting solution that we are putting in place, we can use a wider array of the scrap within the families of painted siding and MLCs.”
He adds, “When we go to the completely new melting technology, that allows us to use the full range of scrap. Because of the environmental controls and the melting solution that we are putting in place, we can use a wider array of the scrap.”
In 2013, JW Aluminum began using Cincinnati-based David J. Joseph (DJJ) as its primary scrap buying agent for its Goose Creek/Mount Holly plant.
“We have three different avenues for us to get raw materials,” he says of JW Aluminum’s approach to scrap sourcing. “I can go directly to my customer and get a closed-loop system in place, and we do in fact have those arrangements in place. We do have arrangements where we will go directly to a yard. And we also have arrangements where we work through DJJ to source products through their yards or other yards in the United States.
He adds that most of the company’s incoming scrap is supplied from within a 300-to-350-mile radius of Charleston, South Carolina.
McCarter says JW Aluminum’s Goose Creek/Mount Holly mill “should be ready to utilize hot metal sometime in the second quarter of 2020.”
The company is running its existing melting and casting operations until the new operation is ready to “turn on” later this year, he says. “But because of the capacity upgrade we are putting in place, this new operation effectively only has to run three-and-a-half days a week, whereas the existing melting and casting operation has to run seven days a week.”
McCarter continues, “When you can make an investment that provides a good return, when you can invest in your teammates and provide them with a return and when you can invest in our country and allow it to become more environmentally sustainable, that seems like a good formula for success.”
As we head into a new decade, platinum group metals (PGMs) will continue to be a vital part of managing carbon emissions globally. This was demonstrated most clearly to me during a recent layover in Beijing. Looking out across the tarmac, it was impossible to see clearly beyond 500 yards. I was shocked at just how bad the air quality was. After asking around, I was informed that locals considered the day to be bright, sunny and clear.
To me, seeing the emissions-related smog in that emerging economy means short- and long-term demand for PGMs will far outweigh the readily available supply, especially considering that both China and India (two of the world’s most populated countries) have only begun to regulate carbon dioxide (CO2) emissions in recent years. Despite reports and forecasts of slowing western economies, the fact that China and India have set particularly aggressive emissions management targets will drive ongoing increased demand for PGMs.
The demand drivers in India and China as these countries go from nearly no emissions standards to those approaching standards applied in Europe and North America should offset any decline in demand that is to come from slowing western economies. So far, strong demand has had considerable upward momentum on PGMs prices.
Most notably, palladium pricing consistently broke records over the last year. At the beginning of December 2018, palladium was selling for $1,200 per ounce. As of December 2019, pricing for palladium was more than $1,800 per ounce. In its May 2019 “PGM Market Report,” Johnson Matthey estimated an 809,000-ounce net demand deficit for palladium in 2019.
It remains to be seen where the market will take palladium prices in 2020, but we reasonably can assume that with stricter emissions standards in highly populated developing countries and without any predicted forecast of increased supply, palladium will continue to sell at a premium.
Platinum pricing, on the other hand, has remained tightly range bound with the height of the market in recent months at $984 per ounce and the low end at $783 per ounce.
Some analysts are predicting increased demand and, therefore, increased pricing for platinum as some automotive manufacturers look for ways to increase their loadings of platinum to reduce the use of palladium in their diesel autocatalysts, but substitution in gasoline applications is more challenging, according to Johnson Matthey.
Regardless of the possible changes in PGM loadings, replacing palladium with more platinum would take many years to accomplish as manufacturers would need to retool their operations and supply arrangements. Additionally, the costs associated with these redesigns and transitions could negate the savings associated with using platinum instead of palladium at today’s prices, particularly if platinum prices exceed those of palladium in coming years. (Platinum originally was used in all catalytic converters for decades until the 2000s, when automakers transitioned to take advantage of the comparatively lower price of palladium at that time.)
Rhodium, not to be outdone by palladium, has increased even more dramatically in value over the last 12 months, despite Johnson Matthey’s forecast for a total net demand surplus of 44,000 ounces for 2019. December 2018 saw pricing of rhodium at $2,300 per ounce, while December 2019 pricing was close to $6,000 per ounce.
Although rhodium is not necessary in diesel engines, it is necessary for catalytic converters in gasoline engines. From this observer’s viewpoint, new gasoline engine automotive emissions regulations being implemented by China and India within the next two years also are driving rhodium pricing.
For the most part, over the last decade, PGMs have been consistently short on supply for many reasons that include mining strikes, power interruptions and political trade sanctions. The simple fact is that the capacity of the world’s mining operations alone cannot meet or sustain global demand for PGMs. This leaves a great deal of room for recycling to help meet demand.

Autocatalyst recycling is the second largest contributor to the world’s supply of PGMs. Using Johnson Matthey’s supply-and-demand figures for the last six years, autocatalyst recycling has contributed on average 23 percent of the world’s PGMs supply. Recycling of jewelry and electrical sources brings recycled PGMs’ contribution to world supply to just slightly more than 25 percent.
While recycling PGMs, especially autocatalysts, can be complex and in some cases financially risky for buyers without extensive knowledge of the industry, recycling remains a far more cost-efficient method for delivering PGMs.
Mine exploration, digging, blasting and transporting require a great deal of financial and physical resources. Collecting spent autocatalysts, while presenting challenges on the buying side, really just means making sure catalytic converters from end-of-life vehicles are being harvested properly and sent to recycling facilities and not to shredders.
Once mined or recycled materials are harvested, they are treated in basically the same way: They need to be crushed, sampled, smelted and chemically separated to achieve pure metal that is ready for sale in the marketplace.
While treatment of both materials is similar, 1 pound of oar-rich rock contains roughly 18.5 parts per million of palladium, and 1 pound of autocatalyst contains 1,850 parts per million of palladium. Therefore, creating the same yield of palladium requires processing 1,000 times more rock than autocatalysts. Similar comparisons, though not as divergent, can be made for platinum and rhodium.
With this stark contrast in yield, recycling will continue to play a significant role in meeting worldwide PGMs demand.
For those of us involved in any aspect of the recycling of autocatalysts in 2020, even more importance could be placed on recycling in the future. With words like, “steelmageddon,” or a price-crushing steel glut, being tossed around, smart auto recyclers increasingly will be looking at the value of autocatalysts in end-of-life vehicles to keep cash flowing.
As long as the world continues to depend on fossil-fuel vehicles and carbon emissions standards are increased, the outlook for PGMs is bright. Hopefully, for the sake of the planet and the people living in emerging economies such as China and India, carbon emissions standards will continue to rise and be enforced. In the coming years, I anticipate passing though Beijing again and hope to see bluer skies.
On the recycling side of the supply equation, the same can be said. If trends continue, 2020 could see recycling’s contribution to PGMs supply reaching closer to 30 percent globally.
If your recycling business is not already involved with autocatalyst recycling, you might want to look at how to carve out your piece of the pie while demand is still growing.

An Imabe PCL-900 shear baler is a complement to existing equipment at Massachusetts-based Sullivan Metals.
William F. Sullivan Co. Inc., Holyoke, Massachusetts, also known as Sullivan Metals, receives a lot of obsolete materials—unprepared No. 1 steel, plate structural and demolition scrap. The company and its four-acre scrap yard have been in the community since 1953. The company also receives a lot of industrial scrap, including clippings and skeletons.
“We have a very, very large industrial base that we’ve developed over the years,” says Brian Powell, vice president at Sullivan Metals.
For a while, the company used just one 1,100-ton guillotine shear to process both the obsolete and industrial grades of scrap; however, Powell says the company had a tough time processing both of those types of materials in the same shear.
So, about eight years ago, the company decided to invest in a second shear that it would place adjacent to the 1,100-ton guillotine shear to work two times as fast. In 2012, Sullivan Metals installed a shear baler model PCL-900 from Miami-based Imabe to process its industrial scrap while the 1,100-ton guillotine shear continued to focus on obsolete scrap.
Powell says the PCL-900 is slightly smaller than Sullivan’s other shear, so it made sense to process the lighter industrial scrap on that machine. Since the installation, the PCL-900 cuts all of Sullivan Metal’s industrial clippings and skeletons and it also helps to log light iron. The machine can bale as well, so it also offers the company with flexibility. Powell adds that the PCL-900 was “the perfect complement” to the other shear.
“The Imabe allowed us to operate quicker,” he says. “We have one machine that focuses on industrial scrap and the other machine that focuses on demolition scrap. We can do both at the same time instead of swapping back and forth and tying up a machine on one product when we could be working on both—which we have plenty of both materials.”
Operating with two shears has also helped to keep inventory levels low, which Powell says is very important in today’s market.
“One of the reasons why we [added the PCL-900] was we ended up getting a lot of industrial skeletons that needed to be sheared, and it was taking us a long time to get through these industrial skeletons,” he says. “You need to move scrap in and out as fast as you possibly can. So, one of the decisions we made by adding this machine is we were going to be more efficient by trying to buy the scrap and sell the scrap within the same marketplace. What we were trying to do is have a 30-day inventory turn on not only our obsolete grades of scrap but our industrial grades so that everything we’re taking in, we’re sending out within the same month. We were trying to do both at the same time so we could turn the scrap around as quickly as we possibly [could] so we’re not caught in market fluctuations.
“Also, the days of a scrap yard having mountains and mountains of scrap piled up in their yards—that’s something in towns people don’t want to see anymore,” Powell continues. “If we’re able to keep our inventory low, not only does it mitigate any market risk we’re up against, but it also keeps our scrap yard where inventory is minimal.”
Since installing the Imabe PCL-900 shear baler, Powell says it’s performed wonderfully. He says the company has had to refurbish the machine for the first time this past fall with the help of Imabe and local manufacturers.
While the refurbishing process is about two months, Powell says having two shears operating side by side reduced any opportunity for downtime.
“Having two machines prevents us from having a complete outage if we plan appropriately,” he adds. “We always have [a shear] that runs.”
The U.S.C. Polisher is a remarkable tool that scrap processors across the country are using to clean material streams.
Based upon customer requests, U.S.C. began prototyping the Polisher during the last decade, engaging in a great deal of research and development to custom design a unit for the scrap industry. Today numerous units operate across the country.
The versatility of the unit and its ease of use allow scrap dealers to achieve cleaner material than they’d imagined and an exceptionally rapid return on investment.
U.S. Conveyor’s proprietary design features an expansion chamber where material meets an adjustable air current. The heavy fraction seamlessly drops from the light fraction quickly and cleanly.
The unit is compact and highly efficient, maximizing and controlling airflow. Available in 30-, 60- and 80-inch sizes for a range of throughputs and easy adaptability with existing processing lines.
The Polisher is easily adjusted through a single control that varies air velocity. Operators quickly get the feel for settings for specific materials, and many have elected to use it offline as a satellite processing step. It can be batch fed with different materials at different times.
”We’re running the polisher on our X-ray line before the sensor. We’ve been able to dial it in to get the foil and other lights out. It’s really improved the performance of our X-ray.
”The combination of the polisher and cassette feeder is like a Swiss Army Knife. It’s very flexible and effective, allowing us to do a lot of things we could not do before.”
”Years ago, we devised ways to recover the trapped ferrous in our fluff. It was always hard to market, however, because of the trapped contamination. We tried numerous ways to clean it up, but nothing did the job until we tried a U.S.C. Polisher. The unit works great. Compact and economical yet powerful and flexible.
”It’s a great value for the money; and, when combined with the cassette feeder, it’s a great tool!”
As with all separation equipment, feeding the polisher properly is essential. Through extensive field testing and production processing, it’s been proven that combining the polisher with a cassette feeder increases the Polisher’s performance.
150mm No.1 2b Ba No4 8k
The unique cassette feeder, offered through U.S. Conveyor’s partnership with Spaleck, combines a vibratory feeder with a flip-flow screen. The cassette feeder pulls dirt and other contamination out before the material enters the Polisher, increasing purity.
The Polisher has been designed and fabricated to withstand abrasive, production-level processing. The unit features easily replaceable AR liners to extend wear life. It also features stout and simple construction that can weather the toughest applications.
