Calcite: its name comes from the Latin calx, which means living lime. It is the most stable mineral that exists of calcium carbonate, it is a very common mineral, and it has a wide distribution throughout the planet. Its chemical form is CaCO3, it contains 56.03% CaO and 43.97% CO2. Ca can be replaced by Mn, Fe, and to a lesser extent by Sr, Co, Zn, Ra, Pn. Present a variety of colors, clear, white or colored in light tones. Its hardness is 3 moh, density is from 2.6g/cm3 to 2.94g/cm3.
Calcium content more than 55.6%, no harmful ingredients, can be used for feed supplement.
It is used as raw material for plastic factory, rubber factory, paint factory, waterproof material factory and for interior and exterior wall painting. The whiteness is above 85 degrees.
Whiteness more than 93 degrees.Used for pipe manufacturing, and applied in chemical industry.
Can be used in toothpaste paste, soap. Whiteness above 94 degrees
For rubber, plastic, cable, pvc whiteness above 94 degrees.
pvc,PE,paint,paint grade products,papermaking primer,papermaking topcoat,whiteness above 95 degrees It has high purity, high whiteness, non-toxic, odorless, low oil quality and low hardness.
Calcite powder processing is generally divided into fine calcite powder processing (20 mesh-400 mesh), ultrafine calcite powder deep processing (400 mesh-1250 mesh), and micro-powder processing (1250 mesh-3250 mesh).

The calcite bulk material is crushed by the crusher to the fineness that can enter the mill(15mm-50mm).
The crushed calcite small pieces of material are sent to the storage hopper through the elevator,and then sent to the grinding chamber of the mill evenly and quantitatively through the feeder for grinding.
Through classification, the coarse powder will return to main mill to grind again.
The powder that meets the fineness enters the dust collector through the pipeline with the air flow for separation and collection, and the collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged uniformly.
