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.

Anthracite For The Production Of Batteries: Casings And

Anthracite in untreated form is a poor electrical conductor, rendering it suitable for casings with little to no processing aside from grinding(4). For electrode applications, calcination (and thus subsequent graphitisation) is required to improve electrical conductivity. Phenomena such as the Rapoport effect are considered as non-issues for these applications(5).
