Our Experience Makes All the Difference
By providing you with a wide range of modular screening products and systems (in various designs and sizes), we can help you increase your material recovery, reduce maintenance needs, and minimize your overall costs.
Our experience in the Coal industry spans more than 35 years, and many of our screen panel designs were specific responses to our coal customers' needs for issues such as magnetite recovery, material plugging, and clay removal. Today, our products are a reliable, cost-effective alternative to traditional coal screening products such as wire cloth and profile wire. Since we understand how extended downtime can cripple production, we also have dedicated warehouses located in the eastern coal fields and the Illinois Basin.
Coal Screening Solutions
The coal industry faces unique screening issues that can impede production. Polydeck offers a wide range of modular coal screening products and systems that can help any mine increase material recovery, reduce maintenance needs, and lower overall costs.
Drain & Rinse
Polydeck's unique polyurethane compound performs very well in clean coal and refuse applications where draining liquids, like water and magnetite, off the material can provide significant cost savings downstream. Our VR (zigzag) design on the top deck and continuous Continuous Slot Design slot design on the bottom deck makes for a very effective combination in extending wear life, reducing or eliminating plugging and blinding, and reducing noise pollution.
Our unique injection molding process enables us to produce screen panels with extremely small openings, down to 0.1mm in size. This capability means we can offer our customers a wide range of small aperture screen panel choices to achieve the most efficient material dewatering. Our excellent quality control provides consistent opening sizes and shapes, panel after panel.
Scalping sizes the raw coal before it enters the plant. Both Polydeck's polyurethane screen panels and rubber screen panels can effectively accomplish this, but rubber panels resist abrasion so well that they provide extended wear life while allowing easy, one person changeout. They are also available in a softer rubber option that resists sticky clay build-up.
Also available for scalping applications is Polydeck's Armadex™ bolt-down rubber solution. This custom rubber screening product uses a proprietary injection molding process along with a premium blend of natural gum rubbers and high-strength low-alloy (HSLA) steel plate backing to produce a product of unprecedented strength, uniformity, and wear life.
Desliming is a process intended to remove ultra fine coal and clays from heavy media feed circuits. Effective desliming results in higher magnetite recovery and fine coal recovery. Our polyurethane screen panels with continuous slot opening designs typically excel in this application because of their outstanding performance and long wear life.
