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.

    GB2192388A Process for leaching silica sand to reduce

    A process for leaching silica sand to reduce the iron content thereof comprises the steps of drying- preheating the sand; vigorously mixing the preheated sand in a suitable intensive mixer, e.g. a rotating pan mixer, with sufficient sulphuric acid (e.g. 7.5 kg 100% H2SO4/tonne sand) to keep the surface of each grain of sand coated with a thin film of sulphuric acid during mixing; and retainingget price
