Calcium Carbonate Grinding Machine

The grinding stage is the key stage of calcium carbonate powder making 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 Grinding Machine

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.

Specialists from SBM suggest the MTW-series Trapezoid mill is the best choice. It adopts the integral transmission of bevel gear, inner light-oil lubrication system and arc whirl tube, which stand for the leading trend of international grinding mills. In addition, the roller and ring are designed in our Trapezoid mill can reduce the material’s slipping speed between rollers and ring, extend grinding time, and enhance crushing effect.

Therefore, mining investors who adopt the MTW-series Trapezoid mill as the calcium carbonate grinding machine can significantly improve the quality and calcium carbonate powder. Besides, it can save the operation cost.
