Efficient Frac Sand Screening
Watch this video on YouTube.
A sand producer was looking to increase production rates at an existing plant by adding new frac sand screening equipment. Their goal was to produce a consistent 40 x 70 API standard product. The feed to the vibratory screening machines would be from a processed material stream that discharges from a hydrocyclone at a solid feed rate of 150 STPH.

A mineral sands producer used new vibratory screening machines (or repulping equipment) to recover garnet at over 90% efficiency. The older, conventional vibrating screens were only able to recover material at about 44% efficiency.

A silica sand wash plant required (4) dual motor vibratory screening machines. These linear-motion screens included high open area 25 mesh urethane screen panels. Spray nozzles were also incorporated into the design for increased fines removal.

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.

Multiple 5 Deck Derrick® Stack Sizer® Installations
The patented, high-volume Derrick® Stack Sizer® provides a much better economic alternative to Hydrocyclone separators, hydraulic classifiers, and less efficient low volume fine screening systems.
Over 300 of the Stack Sizer units have been sold throughout the world for fine screening and dewatering applications that require high tonnage mineral processing.

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.
