DERRICK FINE SCREENING AND FINES RECOVERY TECHNOLOGY

The generation of fine solids are by far the largest concern within the industry. The Derrick HI-G® Dryer provides the most cost effective solution to handling these fines. This proven technology consists of a Derrick high G-force linear motion vibratory screen and a radial design cluster of Derrick 4 inch unibody hydrocyclones.

Since its inception in 1951, Derrick Corporation has been committed to provide the most advanced high frequency screening and solids control technology available throughout the world. Derrick Corporation, based in Buffalo, New York, U.S.A., is a fully integrated manufacturing facility supplying the aggregate industry with a high performance fines recovery system. From rugged, dependable dewatering equipment to our patented urethane and steel screen surfaces, our advancements are proven successful and continue to lead the way for the aggregate industry.

The Derrick Fines Recovery System consists of a cluster of 4 inch unibody hydrocyclones mounted over a HI-G Dryer, high G-force linear motion screening unit. This combination provides the industry with unmatched performance and dependability.

HI-G® DRYER
•  High G-force Linear Motion Machine
•  Super G Vibrating Motors
•  Radial Design Cluster of 4” Uni-body Hydrocyclones
•  Hydraulic Deck Angle Adjustment
•  Rapid Change Bolt Tensioning
•  Long Lasting Urethane Screen Panels

The Derrick HI-G® Dryer is powered by two 2.5 HP electromechanical Super G vibrating motors operating 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 Super G motors feature permanently lubricated, sealed bearings and are designed for maintenance-free operation. Super G motors offer low noise levels resulting in a significantly reduced decibel level during operation, approximately 81 dBA.

The 4” hydrocyclones are mounted on a radial design manifold. Derrick round desilters are designed to efficiently remove silt sized solids (12-74 microns) from plant discharge slurries. Derrick hydrocyclones are available with ceramic inserts for extreme duty. Shut-off valves on each cone inlet permit individual cone removal and inspection without interrupting operation of the desilter. The apex is available in two styles: an adjustable tri-nut or fixed snap-on.

Fast, easy, and reliable screen panel tensioning is provided by two pairs of Rapid-Change draw bolts on each side of each screen panel. Its hydraulic, adjustable while drilling (AWD) is designed for quick, easy deck adjustment and operates from -1° to +5°.
