Grinding Machine for Grinding Fine Stone into Ultrafine Powder - Vertical Mill

Calcium carbonate is a compound with a chemical formula of CaCO3. The CAS number is 471-34-1. It is a common substance on the earth and can be found in rocks. The main components of animal back shells and snail shells. It exists in nature with two minerals, calcite and aragonite. Calcite belongs to the trigonal system and is a hexagonal crystal. The pure calcite is colorless and transparent, generally white. It contains 56% CaO, 44% CO2. The density is 2.715 g/cm3, the Mohs hardness is 3, and the properties are brittle. Aragonite belongs to the orthorhombic line. It is a rhomboid crystal, gray or white, with a density of 2.94g/cm3 and a Mohs hardness of 3.5-4. It is dense. The crystal size of calcite in the physical properties of limestone is very important. The dense limestone exhibits a low porosity and a fine grain crystal structure with high strength.

After the limestone is processed by the crushing equipment, it cannot meet the requirements of the finished product, and it needs to be ground by a mill to obtain the finished product. For grinding limestone powder, vertical grinding mill can be used. For fine powders, vertical mills can be used in the field of limestone grinding. The vertical grinding mill is the excellent grinding mill machine. The vertical grinding mill has comprehensive mechanical pulverization properties such as rolling, grinding and impact. The fineness of the powder can be adjusted between 325-2500 mesh, so it is available in the production of fine powder processing of non-metallic minerals. After market practice certification, the mill is the ideal equipment for energy saving.
