Industrial Calcium Carbonate Introduction

Common calcium carbonate powder includes the following species: coarse whiting, activity calcium carbonate (ACC), light calcium carbonate, nano calcium carbonate. Coarse whiting is also called ground calcium carbonate (GCC), processed from natural calcium carbonate mineral (such as calcite, limestone) by grinding mills or vertical mills. Light calcium carbonate is also called precipitated calcium carbonate (PCC), is made by chemical processing. For the settling volume of mechanical ground calcium carbonate is lower than chemical processed calcium carbonate, so the ground calcium carbonate is called heavy calcium carbonate. Activity calcium carbonate: modified from normal calcium carbonate. The modifying including crystal habit, particle size, fineness distribution and surface performance, in order to improve overall performance of calcium carbonate material. Nano calcium carbonate is also produced by chemical processing, but the particle size is much smaller, crystal habit is also different from normal calcium carbonate material.
Guilin Hongcheng HC Series Grinding Mill is a good equipment in calcium carbonate processing. HC Series Grinding Mill widely applied in mineral grinding processing of metallurgy, construction material, chemical industry and mine fields, and is widely used to grind minerals with Mohs hardness below 7 and moisture below 6%, such as limestone, calcite, active carbon, talc, dolomite, titanium dioxide, quartz stone, bauxite, marble, feldspar, barite, fluorite, gypsum, titanium iron ore, phosphate rock, argil, graphite, kaolin, diabase, coal gangue, wollastonite, slaked lime, zircon sand, bentonite, manganese, etc. The fineness can be adjusted from 0.18mm to 0.038mm (80-600 mesh).
