1 To pulverize crushed coals in a ball mill, you start by feeding the mill with crushed coal. Then the grinding media crushes and grinds the coal in the rotating chamber. 2 Airflow carries the pulverized coal out of the ball mill. 3 Next, you'll need to use the mill classifier to separate the fine coal particles from the airflow.
The OKTM mill can skilfully grind raw or cement feed material and offers parts commonality, simplifying spare parts inventory and facilitating easy switching of parts between vertical roller mills.

Ball grinding can be carried out in either dry-operation or wet-operation. The former is widely used in coal-fired power plants and cement industry, and the latter is widely used in metal and nonmetal mines. There are three types of mills used: grate ball mill, overflow ball mill, and peripheral discharge ball mill.
1. Introduction. Anthracite is widely regarded as the cleanest burning coal owing to its high heat output and minimal smoke production and possesses the highest fixed C and lowest volatile matter contents [1].The coal structure is generally considered to be extremely complex [2], [3].Researchers have extensively analyzed advanced …
