GN decanter centrifuge for aluminum hydroxide slurry

18 January 2019

Many chemical products manufacturers need decanter centrifuge to dewater the slurry in their production processing. One client from the chemical industry found GN decanter centrifuge can do the slurry dewatering job for concentration.

The client has the aluminum hydroxide slurry concentrated from 8% to 10% to 60% to 80% by removing the water. The slurry is composed from water, fine aluminum hydroxide particles and little bit sodium nitrate. Client came to GN factory and watched the demo. GN decanter centrifuge performance satisfied client.

GN developed the decanter centrifuges for other separation solutions such as waste water treatment, oily sludge recovery, chemical slurry dewatering and ore washing. The developments are mainly focusing on the bowl diameter and length ratio and the cone angle. By changing the factors, GN decanter centrifuge will do purification, classification and concentration per users’ purpose.

GN dewatering decanter centrifuge ranges from 9 to 30 inch with different capacity for specified requirements. In latest longer bowl decanter centrifuge, for better anti-corrosion performance, GN use the duplex stainless steel 2304 as the bowl material, and screw propeller is made from stainless steel of 2205 instead of 304. This guarantees the long time running in chemical products processing.
