The popular marketing requirement of cac03 powder size is from 600-1500 mesh. To satisfy caco3’s marketing needs and final profits, there should have following factors for powder machine and technology choosing, such as mutual technology, quality products, stable equipments, low consumption, and less investment

Dry method processing technology equipment are Raymond mill, impact mill, mixing mill, vibrating mill, ball mill, roller mill and vertical mill,etc.
Raymond mill is mainly used to produce 200-400 mesh powder (matching classifier machine can grade material to 800 mesh, but the production capacity is very low.)
Impact mil and vibrating mill can process caco3 to 800-1500 mesh, but with high consumption and low production.
Mixing mill is equipped nano classifier, that can produce 1250-6000mesh powder, but the production capacity is also low.
Roller mill is used to grind 800-1500 mesh powder, with advantage of low consumption, but capacity is not high for single machine.
Ball mill plus super fine classifier can grind 600-2500mesh super fine powder, its product capacity is high, but disadvantage is high consumption.
Vertical mill is with high capacity of single machine. Its production capacity can reach 40-60tph for different range powder size. And, it combines dry, grinding, classifier and elevator together, can totally meet different needs of client.

So, the ideal equipment to produce 1250 mesh caco3 powder is vertical mil, second choice is roller mill.
