Comminution is applied in all mineral processing plants where mineral liberation is needed for separation and concentration of valuable minerals. The process is energy intensive and is predominantly carried out in tumbling mills which are known to be highly inefficient. Comminution technologies utilised in other industries, such as the vertical roller mill …

Classification in an air classifier is the result of opposing forces in the system. Typically, the classifier comprises a rotating disk that imparts an outward centrifugal force on the particle. Opposing that force is the inwardly moving air flow that provides an inward force on the particle. Both the outward centrifugal force and the …

A dry upgrading technique that is suitable for the separation of fine-particle coal has yet to be developed. Today, ultrafine pulverization is primarily used to purify or modify metallic or nonmetallic minerals. Few studies have considered the use of ultrafine pulverization for mineral purification and dissociation with coal as the raw material.

Additionally, the precise classifier (of inertial-impingement type in this installation 25) requires higher air flow rates than the working chamber of the mill. Thus, extra air needs to be ...
