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.

    Ultrafine Grinding an overview ScienceDirect Topics

    3.3.8 Response to Ultrafine Grinding CIL UFG of pyrite concentrates for subsequent leaching is used in ores, where refractoriness to direct cyanidation arises from fine to ultrafine (<20, >0.02 μm) gold mineral inclusions in the pyrite and/or arsenopyrite.get price

    Effect of grinding parameters on the rheology of pyrite

    Jun 01, 2007 As the cracks and defects of pyrite reduce when the particles decrease to micron dimension, it is difficult for pyrite to comminute on wet ultra-fine grinding. Another possible reason is that special surface area and surface energy increase simultaneously, which leads to the agglomeration of particles and the observable increase of viscosity.get price
