Calcium carbonate is one kind of widely used basic material. Daswell has much experience and projects, with full solution from crushing, to medium size grinding to ultra fine grinding, for different application such as filling compound, paint, ink, paper and so on.
In the last years, Daswell has finished the top class big scale calcium carbonate in China and other countries such as Egypt.
Vertical mill is very suitable choice for the product size bigger than 10 micron, including the 10 micron.
The power consumption will be less 30% than ball mill for the 10 micron and coarse, and also it is with a big capacity.
