Product Line

Calcium carbonate, a low-cost bulk commodity. is usually quarried and used close to source rock. It’s good quality material for the production of cement and high-grade lime. Calcium carbonate is not only the main component of marble, limestone and dolomite, it is also found in bones and teeth as well as the exoskeleton of crustaceans, coral, muscles, snails and protozoa. calcium carbonate powders are widely used in rubber,plastic, paper making, printing ink, cosmetics, toothpaste, and food industries.

Calcium Carbonate Quarry Crushing Plant
Calcium Carbonate Limestone (marble) crushing unit includes crushers, ball mills and air classifier powder concentrator and other machines. The final products are stone powder with mesh size 400/37 micron, 800/18 micron, 12 micron and 8 micron. And the capacity is about 2 to 4 tons per hour.

Preliminary work is mainly designing. According to the characters of local stones (limestone/marble) such as humidity and rigidity, Xuanshi has designed the complete Calcium Carbonate Limestone (marble) crushing production line which satisfy the demand for capacity. Now the complete crushing unit has been transported to there, and is being installed and debugging.

Calcium Carbonate Powder Grinding Plant
The feed material like crushed calcite, Aragonite, Vaterite is fed pneumatically through a venturieductor into the grinding mill. The particles are pulverized by a high speed agitated grinding media. The grinding media can be stainless steel, chrome steel, alumina or zirconia. The micronized particles are entrained in the air stream and exit the grinding mill in a high efficiency air classifier. The on size particles are separated and the oversize returned to the mill for regrinding.The grinding media does not discharge from the mill.

The raw materials which are used to produce calcium carbonate can be calcite, marble, limestone,graphite, chalk, marble, travertine, dolomite, bones and teeth etc. The final powder of the grinding mill can be ground down to 3000mesh (or 5micron).
