Mill Speed an overview ScienceDirect Topics

The coal-milling product is pulverized fuel PF containing grains with a different size (polydisperse product). The degree of comminution can be defined using the R x = f(x) function referred to as the pulverized material grain-size characteristic. Parameter R x denotes the mass content of the dust specimen particles, which are bigger than size x.

Pulverizer Wikipedia

Types of coal pulverizers. Coal pulverizers may be classified by speed, as follows: Low Speed; Medium Speed; High Speed; Low speed Ball and tube mills. A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods.
