Superfine calcium carbonate powder is one kind of filler,  which has been used widely,  therefore,  Calcium carbonate powder processing technology and equipment is important field of our scientific research and development.

Calcium carbonate dry processing, adopt international standard ball mill+air classifier system, energy saving, high efficiency, high capacity, exact classification precision and advanced international level.

Ball mill

Using special design and optimizing reasonable Length-to-diameter.

Using the scientific proportion of grinding medium,to achieve the ideal grinding fineness.

Using rolling bearing as main bearing, dry oil lubricating, without thin oil lubricating station, reduced the operation cost.

Air classifier

Using different types of air classifier and classification technology, through to adjust air classifier, make the product and size distribution to meet customer requirments.

Using single or more air classifier, can get different fineness of products at same time. Multi-rotor air classifier, the classification efficiency can reach 90%.

One-time can get fineness 32-52500mesh which is adjustable,  can add another air classifier system, this is advanced level of dry method ultrafine classification at home and abroad.
