Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% ...

Pin Mill Basics. Pin mills are available in two basic configurations: horizontal or vertical shaft. In a vertical shaft pin mill, as shown in Figure C, stationary pins are screwed or bolted onto a stationary disc (called a stationary mill plate), which is located above a rotating disc (called the rotor). Pins are also mounted on the grinding rotor.
The literature [1], [2], [3], [4], [5], [6], [7], [8] has reported significant attempts to model vertical spindle mills (VSM), which are dominant in pulverised fuel (PF) production in coalfired power stations, and are also applied in the cement and mineral industries.
