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.
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.
During the mining 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.
Specialists from Zenith 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.
Zenith can design and install a complete set of calcium carbonate powder production line. Zenith is specialized in producing mining machinery and equipment according to the needs of our customers. Typically, our calcium carbonate powder production line consists of the conveying system, feeding device, crushing plants, grinding plants and automatic packing machinery. Nowadays, more and more quarry owners choose our calcium carbonate powder processing line, in their opinion, they think the calcium carbonate production line designed by Zenith features high capacity, reliable performance, easy maintenance and low operation cost.
