NHD-serial deep cone thickener is developed and successfully applied in alumina for red mud separation and washing system to increase solid content in red mud, which bring treatment of alumina tailings into a new stage.

·Excellent Performance

Capacity of NHD-serial deep cone thickener is 15 times as much as common thickener capacity while the underflow compressive ability is almost 10 times as common thickener. Rational structure design can minimize destruction to wooly masses during dilution flocculent feed.

·Process Index

Solid content in final washing supernatant    ≤0.g/L

Solid content in final washing underflow     46-53g/L

Alkali in final washing underflow            ≤ 5Kg/t

Multi-drive, heavy load rotary bearing and bath lubrication are applied in NHD serial thickeners. Torque can be detected accurately by instrument and signal will be sent to user’s control center.

·Advanced Monitoring System

NHD-serial deep cone thickener together with DCS can monitor material in Omni-direction, which integrates related equipment and process data to control automatically. NHD introduces UK technology and measure slurry level and solid content by ultrasonic, providing data for control system.

·Scientific Theoretical Support

NHD imported three-dimensional flow field analyzer of ADV Doppler and world-leading fluid software Fluent to stimulate flow in tank, and makes the best design according to specific conditions of customer.
