GN Full Series Decanter Centrifuge for Different Applications

Decanter centrifuge is main equipment in GN’s production line. Based on the most popular model 14 inch decanter centrifuge used in oil and gas solids control system, GN developed several models decanter centrifuge that could be used for different applications.

GN’s 9 inch decanter centrifuge model of GNLW223 is bowl diameter of 9 inch and the designed capacity is 6 cubic meters. With a high working speed up to 3800rpm, this model is always used for fine solids removal. As it has small capacity, it is often used in diamond core drilling for geology research and some other mining projects.

GN’s 14 inch centrifuge is widely used in solids control system and waste waste management system. GN uses material of SS2205 as the bowl material for a better dynamic balance. The protection of screw propeller is using bolted tungsten carbide tiles thickness of 4mm for longer lifetime. This model is both fixed speed and VFD model for customer’s option. Low speed used in traditional solids control for barite recovery and high speed model used for ultra fine solids separation and waste cutting management. 

GN’s 18 inch decanter centrifuge is mainly in Mud Cleaning System system for barite recovery, it has a relative low speed of 2000rpm that is the best speed for this job. GN has two configurations for this 18 inch centrifuge with different material, speed and driving method. Economic type is especially for the customers who want to save on the equipment cost.

GN’s 22 inch decanter centrifuge has designed normal capacity of 90 cubic meters, which is an ideal choice for large flow rate project. One of GN solids control ’s 22 inch centrifuge unit ever been used in dewatering unit for flocculated fine solids separation. The long bowl can provide a long time for separation for a better expected result.

GN’s decanter centrifuges are always assembled with other equipment like shale shaker units or cuttings dryer unit to become a modular system for multi-function application. Any interests on GN’s centrifuge unit, feel free to contact with us.
