Purpose Of Screens In Coal Preparation

Purpose-built coal breakers are more economical for a given capacity, and so most coal breakage is carried out using rotary breakers, roll mills sizers, and sometimes hammermills.Sizing of the coal using screens and hydrocyclones allows each part of the preparation plant to be designed for treating a particular coal size range.

We are a mining equipment production and sales company, with three production bases and four research institutes, more than 600 production equipment, precision production, and service globally.
