Coal Beneficiation Multotec

Designing a typical flow sheet for your coal beneficiation application. Finer coal particles are fed from the sizing screen to a desliming screen to remove ultrafine coal particles. Ultrafines are fed through a classification cyclone, flotation, spiral separators, screens and centrifuges or filter presses. Less fine particles are fed through a DMS cyclone, screens and centrifuges.

TECHNOLOGIES IN USE FOR THE PROCESSING OF FINE COAL ...

Abstract. Coal is the most abundant fossil fuel and about 42 % of the world electricity is generated through coal fired power stations. However, mechanized mining has led to an increase in the quantity of fine coal production. The value of the fine coal necessitated the selection of the correct equipment for the gravity beneficiation of this coal.
