Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The other polymorphs are the minerals aragonite and vaterite. Aragonite will change to calcite at 380-470°C and vaterite is even less stable.CALCITE is a carbonate of lime (CaCo3). It is also known by the name calc-spar.
Calcite material first through jaw crusher to crushed into the desired particle size, the calcite material by hoist sent to storage hopper, then sent by vibrating feeder evenly, quantitative and continuously fed indoors calcite grinding mill for grinding, calcite after mill machine grinding with wind air rising, through the powder separator graded in line with the fineness of the powder will flow through pipes into the big cyclone collector, collecting separated by a discharge valve is finished calcite powder product.
