In recent years, the exploration, development and utilization of mineral resources have been very active, and market demand is growing. Limestone is a common non-metallic mineral and a valuable resource for a wide range of uses. The main component of limestone is calcium carbonate. With the development of science and technology, limestone processed by new grinding equipment has a new development in the field of application.

Limestone milling type

Limestone powder is generally divided into limestone coarse powder processing (0-3mm), fine powder processing (20 mesh-400 mesh), and ultrafine powder deep processing of limestone (400 mesh - 1250 mesh) and micropowder processing (1250 mesh - 3250 mesh) ) four types.

What kind of grinding equipment is used to process limestone?

At present, with the upgrading and improvement of limestone powder products required by the downstream application industry, vertical roller mill has become the main equipment for large-scale and refined production of limestone powder, which can directly produce 325-600 mesh calcium carbonate micropowder products. Other ultra-fine grinding equipment is used to prepare ultra-fine calcium carbonate products. Chaeng GRM vertical mill developed by advanced grinder technology at home and abroad to integrate fine crushing, grinding, drying, powder selection and conveying functions. It has high production efficiency, energy saving and environmental protection, and good finished product quality, which meets the needs of limestone product processing.

What is the performance of the GRM vertical mill?

Compared with the ball mill processing limestone, GRM vertical mill has advanced production technology, adopting the principle of rolling and shearing, and the powder particles that meet the particle size requirements can be taken away with the airflow in time, thus avoiding over-grinding and low power consumption per ton of products. And the vertical roller mill system is operated in a fully enclosed environment to avoid dust spillage, dust pollution and clean environment, and which is line with the national energy conservation and emission reduction policy.
