MTW European Trapezium Mill has a large market share in the grinding industry. Whether bevel gear overall drive, inner automatic thin-oil lubricating system or arc air channel, these proprietary technologies makes machine advanced, humanized and green.
Applications: Cement, coal , power plant desulfurization, metallurgy, chemical industry, non-metallic mineral, construction material, ceramics.
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.
Magnetic separation of weakly magnetic iron mineral fines in the form of flocs, which is termed Floc Magnetic Separation (FMS) process, has been studied in the present work, in order to find a substitution for high-intensity or high-gradient magnetic separators to treat the ores with weakly magnetic iron minerals in the fine size range.
