About calcium carbonate ultra-fine powder mill plant

Calcium carbonate is an inorganic compound that is the main component of limestone and calcite. It has types of heavy calcium carbonate and light calcium carbonate. Heavy calcium carbonate and light calcium carbonate are different in particle size, crystal shape, and interface properties. The characteristics are also very different. Calcium carbonate is usually used as a filler, artificial floor tiles, rubber, plastics, paper making, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc
The production process of heavy calcium carbonate includes:
Firstly, the raw material including calcite, limestone, chalk, shells, etc. transported from the quarry are selected by hand to remove the gangue; then the stones are crushed with a stone crusher, and then feed crushed material to HGM powder grinding mill to obtain ultra fine powder. Finally Use a classifier to classify the milled powder, and the powder that meets the particle size requirements is packed into the warehouse as a product, otherwise return to the calcium carbonate powder mill for regrinding.
HGM series calcium carbonate grinding mill machine is mainly suitable for ultra-fine powder processing of non-flammable and explosive brittle materials with medium and low hardness, Mohs hardness ≤ 6, such as calcite, chalk, limestone, dolomite, carbon black, Kaolin, bentonite, talc, mica, diatomite, barite, gypsum. It can be adjusted freely between 325-3000 meshes after being processed by HGM grinding mill.

Performance characteristics of calcium carbonate grinding mill:

1. High efficiency and energy saving. In the case of the same finished product fineness and motor power, the output of this calcium carbonate mill is more than double that of jet mill, stirring mill and ball mill.

2. Long service life of wearing parts. The grinding roller and grinding ring of the calcium carbonate mill are forged from special materials, which greatly improves the utilization degree. 

3. High safety and reliability. Calcium carbonate mill has no rolling bearings and no screws in the grinding chamber, so there is no problem of easy damage of bearings and seals, and no problem of easy loosening of screws and damage to the machine.

4. High product fineness. The fineness of calcium carbonate processed by calcium carbonate mill can reach D97≤5μm at one time.

5. Environmentally friendly and clean. The pulse dust collector in HGM grinding plant is used to capture dust, and the muffler is used to reduce noise, which is environmentally friendly and clean.
