A mill is a machine that is used to break down solid materials into smaller pieces by cutting, grinding, or crushing. The process of milling includes the use of force that acts on a material to tear it apart and reduce its size. Milling improves the performance of ingredients, and the products made from them.

How to choose dry and wet ball mill. 1. Correctly choose the feeding way of dry grinding and wet grinding. Whether feed the material dry or wet depends entirely on the subsequent operations in the ball mill and the nature of the produc Some materials require dry grinding because they will undergo physical or chemical changes after adding water.

Wet Ball Mills are Ball Mills that are used widely in the ore beneficiation industry,as well as the building material industry such as glass.. During the producing phase, the material and water are mixed together to grind in the ball mill. Under the effect of the flowing water,the material will get a better flow ability so the processing capacity will be higher.
