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.
