3.Due to the closed operation, there would be no dust. For facilitating the recovery of ultrafine powder, it uses the protective cover discharge for dry grinding that ≥50L and the minerals and steel ball automatically separate so that the discharge will be quite convenient. As a result, the recovery rate of the grinded materials can be up to

1. Introduction. Comminution of the ore can take up to 30–50% of the total operating costs of mining (Aldrich, 2013, Jeswiet and Szekeres, 2016).The most energy intensive process in the comminution is grinding, for which the operation cost increases with the fineness of the product (Wang and Forssberg, 2007, Jeswiet and Szekeres, 2016).Generally wet …
