Deep Cone Thickener

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

Excellence 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 ≤ 0.2g/L

Solid Content in final washing underflow 46˜53%

Alkali in final washing underflow ≤5kg/t

Super output torque:

Drive is a key part for any kinds of thickeners. High solid content and high compression ratio means that drive can operate long term steadily under heavy load. Multi-drive, heavy load rotary bearing and bath lubrication are applied in NHD serial thickeners. Toruque can be detected accurately by instrument and signal will be send to user's control center.

Advanced Monitoring System:

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

Automatic Thickener

Thickener is gravity sedimentation equipment to separate liquid-solid mixture of homogeneous phase. It is extensively used in industries, such as thickener applied in mineral processing plant, separating fine mineral from water, thickener applied in chloride-alkali plant to separate salt mud, thickener applied in waste water processing plant, and wet process phosphorus acid etc. The thickener collects slurry to center by scraper and then discharges from the outlet. The common failure in operation is that motor is overloaded and tripped and sometimes the arms will be twisted because sediment mud can not be discharged in time, which accumulates on the bottom and increase the difficulty for thickener operation.

Overload alarm and motor trip are applied to guarantee security in production. Once alarm sounds or motor stops, normal production can not be resumed until scraper is lifted. If there is no effective measure to decrease thickness of sediment mud, the mud will increase so high that it is forced to stop to clear tank.

The torque indicator designed by NHD can solve problem referred above. It can detect torque changers in operation at real time and adjust process data to balance sediment mud and discharging slurry, which can control torque in set range and guarantee stable production. Meanwhile, it can alarm and stop to protect mechanical parts when torque increase by improper operating or accident.
