mining machinery for small coal seams

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 Mining Machinery Development As An Ecological

2017-4-15  For the last decade the intensive development of mechanic methods of coal mining has led to a signifi-cant deterioration of the coal quality. According to statistics even in 1975 the mechanization level (for coal seams with the dip angle up to 35 degrees) in major coal regions of Russia was 73.7-90.0%. Now its indicator has reached 100% [1-2].
