The South African coal industry makes use of these mills. For normal use, the units are supplied with a cloth collection bag, which also serves as an effective air filter. A specification feature is long-life roller and ball bearings, enclosed and lubricated for trouble-free service over extended periods of use.
Coal moves from the bunkers to feeders to be measured and moved to pulverizers. Coal enters the pulverizer and spins in a large drum where hundreds of steel balls grind it into a fine powder. Now a fine powder, the coal leaves the pulverizers and heads to the boiler. About 335 tons of coal can be pulverized per hour.
