Pulverizer - Wikipedia

Beater wheel mills are designed to prepare a coal powder air-fuel mixture for combustion in furnace chambers of coal-freed power plants by coal drying, pulverizing, classifying and transport. Their multipurpose function usually results in operation instability accompanied by unacceptable vibration. This usually is a significant problem due to unplanned shutdowns. Beater wheel mill maintenance ...

The HGI provides an approximation of the behavior of coal in utility boilers, with the estimated pulverizer mill capacity based directly on HGI. According to Fitton et al. (1957) and that reported in Hower (2008), a 53 HGI coal requires 2.5 times the number of revolutions as a 110 HGI coal to produce a fineness such that 80% of the product can pass a 200 mesh (75 μm) screen.

Ball mill - Wikipedia

Ball mills are used for grinding materials such as coal, pigments, and feldspar for pottery. Grinding can be carried out wet or dry, but the former is performed at low speed. Blending of explosives is an example of an application for rubber balls. For systems with multiple components, ball milling has been shown to be effective in increasing solid-state chemical reactivity. Additionally, ball ...
