Derrick Corporation is considered
the world leader in the design and manufacture of wet or dry
fine screening equipment and screen surface technology used
to screen a wide variety of materials in the range of 3/8 inch
to 400 mesh (10 mm to 38 microns).
The Derrick HI G Dryer with the 4 inch hydrocyclones are mounted
on a radial design manifold, which is fed the wash plant discharge
under a consistent pressure of 35 to 37 psi. The centrifugal
separation extracts the ultra fine sands and silts discharging
them out the underflow. The fines are leaving the hydrocyclone
at approximately 55 to 60% solids where they are fed to our high
G-force dewatering screen. The Derrick HI-G Dryer dewatering
unit is outfitted with two 2.5 hp electromechanical vibrators
that operate at 1,750 rpm with a stroke length of 0.19 inches.
The combination of stroke length and rotation speed create 7.3
G’s of acceleration on the screen surface, resulting in
efficient separation of water from the fine solids. The dewatered
fine solids are then discharged from the screening machine at
75 to 80% solids.
Quality, innovation and reliability are our pledge today and
for the future.
