Hi-G® Dewatering Machine

The Derrick HI-G® Dewatering Machine provides the most cost-effective solution to handling fine solids separation. Derrick’s HI-G Dewatering Machine consists of a cluster of 4″ hydrocyclones mounted over a high G performance linear motion screening unit, 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
