Coal Washing Control System

Product Description

Coal Washing Control System


Coal preparation, which may also be called washing, cleaning or processing, is the methodology by which coal feedstocks are upgraded in order to reduce freight costs, improve utilization properties and minimize environmental impacts. The upgrading, which occurs after mining and before transport of the cleaned product to market, is achieved using a variety of low-cost solid–solid and solid–liquid separation processes. Examples of processing technologies used by this industry include screening, classification, dense medium separation, gravity concentration, froth flotation, centrifugation, filtration and thickening. Several of these processes also play an important role in environmental control for the preparation facility.



Control System for the Whole Process






Product Features

Strong environmental adaptability: can adapt to the harsh industrial site environment.

Highly corrosive environment: Automated Control Services is made of corrosion-resistant materials and can adapt to most corrosive environments such as strong alkalis.

There are no special requirements for the composition of the materials to be measured: Classification Control System is not affected by bubbles; Automatic Grinding System is low affected by large particles; Benificiation Process Control is not affected by magnetic interference.

The detection range of particle size is wide: the maximum size range of 60 percentage points can be detected, and the minimum size range of 20 percentage points can be detected.

The size fraction span is large: Beneficiation Automation can be achieved in the diameter of the grain between 20μm to 1000μm.
