- Eliminated dry sizing stage typically needed to meet quality speciﬁcations
- All products meet or exceed frac sand speciﬁcations
- Equipment ﬂexibility allowed rapid response to revised marketplace demand for increased 40/70 production
Dewatering screens, or wet screens, provide a wide range of sizing and classification tasks. Wet screens efficiently screen out fines and classify oversize particles. All Derrick machine dewatering units have a proven throughput of up to 300 tons per hour and are designed to maximize solids recovery and minimize wastewater.

The Derrick machines provide a high capacity, high efficiency separation of fine wet particles. The multiple screen deck surfaces increase screening capacity by up to 3 times that of the best fine mesh screens currently available. The Hi-G dewatering screen provides 7.3 G's of screen surface acceleration for maximum water and fine solids separation.

A wet frac sand tailings stream is processed to recover valuable product before wet sand tailings are sent back to a quarry. Water and silica sand are processed over a urethane screen panel designed to remove any remaining product from the tailings stream.
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.
This industrial sand processing and sand washing equipment produces a clean and dry industrial sand that contains less than 2% -200 mesh at a rate of 150-175 t/h.

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.
