GN Decanter Centrifuge Ltd applications

Decanter centrifuge is used as the 4th phase solids control equipment after shaker, desander and desilter. The centrifuge suck the mud from the compartment receiving the discharge from the desilters and mud cleaners, and the returned stream is directed to the next compartment downstream. The use of decanter centrifuge with the drilling mud is (1) removal fine solids from unweighted fluids (2) selection separation of colloidal and ultra-fine solids from weighted fluids to improve their flow properties.

Drilling waste management and cuttings disposal have become a critical issue for any drilling operations because of stringent effluent limitations on the discharge of contaminated drill cuttings to the environment. The wastes discarded by the drilling mud circulation system must be disposed in safe way to the environment. GN Solids Control offers Vertical Cuttings Dryer and Big Bowl Decanter Centrifuge to dramatically reduce total volume of drilling wastes to diposal and revover much clean fluids back to the mud circulation system. GN offer a complete package of drilling waste management tank system as well.

GNLW223 Series Mini Centrifuge is specially designed for small capacity, small footprint, and fine solids separation. It is designed to meet the drilling fluids recycling for mining drilling rigs especially for diamond drilling. The diamond drilling contract can choose to buy single centrifuge unit with electric drive fixed speed or VFD drive variable speed or even the Fully Hydraulic Drive. For the FHD drive Centrifuge, it can use the diesel engine to power the hydraulic pump to feed to the centrifuge without any electric. GN also has the completed tank system with Mini Shaker for option!
