coal mill control process

Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

Coal mill control process EVT Energie- und

1992-10-26  The coal to be pulverized is delivered from a bunker 1 to a coal metering hopper 3 via a supply conduit 2. The metering hopper 3 is controlled, in the manner to be described below, so as to deliver measured quantities of coal to a roller mill 5 via conduit 4. The air which entrains the coal dust produced by mill 5 is provided by a blower 9.
