Carbon Black Grinding Machine Process

The grinding stage is the key stage for calcium carbonate mining process. Particles of calcium carbonate are fed pneumatically 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 mill in a high efficiency air classifier. The on size particles are separated and the oversize returned to the mill for regrinding. The process for fine ground and ultrafine ground calcium carbonate produced in a ultrafine dry grinding mill in closed circuit with a high efficiency air classifier. After this grinding process, calcium carbonate powder can achieve to 1 micron or less.

Calcium Carbonate Production Line

Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks in all parts of the world, and is the main component of shells of marine organisms, snails, coal balls, pearls, and eggshells. Calcium carbonate is the active ingredient in agricultural lime.

The vast majority of calcium carbonate used in industry is extracted by mining or quarrying. Pure calcium carbonate, can be produced from a pure quarried source (usually marble). Alternatively, calcium carbonate is prepared by calcining crude calcium oxide. Water is added to give calcium hydroxide, and carbon dioxide is passed through this solution to precipitate the desired calcium carbonate, referred to in the industry as precipitated calcium carbonate.
