These dry urethane screen panels were used on 16 vibratory screens to classify dry frac sand. The highly abrasive 20 to 120 mesh frac sand was causing rapid wear of the existing wire mesh screens. Average failure of the wire mesh screens was occurring in 3 to 5 weeks at a flow rate of 20 tph.

Derrick Stack Sizers 5 deck for fine screening and dewatering mineral processing
The Derrick Stack Sizer is a high-frequency, multi-deck screening machine used for fine screening and dewatering in mineral processing applications.
It is designed to achieve high screening efficiency, high capacity throughput, and a significantly smaller footprint compared to conventional screening equipment.
Stack Sizers are commonly used for separations down to 38 microns and are widely applied in mineral sands, iron ore, silica sand, and other high-tonnage processing operations.
It is a much better alternative to hydrocylcone separators, hydraulic classifiers, and less efficient low volume screening systems.

This heavy-duty vibrating screen for fertilizer is four feet wide by eight feet in length. It has dual, top-mounted industrial vibration motors that shake the screen. The screen is designed to scalp phosphate rock at a rate of 150 tons per hour. It removes agglomerates and foreign matter, while producing less than 2% overs. The slope of the discharge funnel and support structure were specially designed to accommodate the customer’s existing collection type, troughing belt conveyor.

Final dewatered ash, or char, being fed off the dewatering screen
This boiler ash handling and recovery system is designed to remove unburned carbon (char), ash, grit, and sand from wastewater discharged from a wood and bark power boiler. Slurry, composed of water and solids, is sent from the wet precipitator to the dewatering screen at rates of 800 to 2,200 GPM. The HI-G dewatering screen uses (2) low horsepower, industrial vibration motors to apply a high G-force on the urethane screen panels. This separates the water from the solids.
