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.

Dewatering Process an overview ScienceDirect Topics

It was also observed that, unlike the existing fine coal dewatering processes, the performance of the NDT™ system is not dictated or constrained by particle size, i.e. it works equally well on 1 mm × 0 coal as it does on 44 μm × 0 coal. The process overcomes problems associated with other techniques for fine coal drying since dewatering occurs at ambient temperature and low

The process of dewatering by displacement is capable of achieving the same level of moisture reduction as thermal drying but at substantially lower energy costs. Fine coals are dewatered in an energy efficient process in which a non-polar liquid or a mixture of different hydrophobic liquids are used to displace the water from the coal surface. This process works with higher
