Calcium carbonate mining using milling equipment

Posted by kuangshanposui on June 13th, 2019

During the Raymond Mill Price And Quality process of calcium carbonate, grinding machine performs as an important type of calcium carbonate processing machine. Typically, calcium carbonate grinding machine refers to the main calcium carbonate powder making machine used in the calcium carbonate processing plant. As for the type of calcium carbonate grinding machine, mining investors can choose the ball mill, Raymond mill, and vertical mill, etc.

The micronized Ultrafine Mill Manufactures 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. Secondly, use the raw material drying air swept mill technology. The improved closed-circuit raw material mill still can realize high output even when the water content of the fed raw materials is as high as 3.5%, and the reformation cost of a Φ2.2*7m raw material is just a thousand Yuan and the time for reforming the grinding mill will not exceed 24 hours, and the output per unit can be improved by 20~80% on the same condition.

Calcium carbonate powder is an important material in many industries.The mining process of calcium carbonate mainly consists of the crushing stage and grinding stage. When large calcium carbonate stones are loaded to the working site, they will be conveyed into the crushing machines to turn into the calcium carbonate particles, which then 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.
