dry ball mill is widely used in cement, silicate product, new building material, refractory, fertilizer, black and non-ferrous metals and glass ceramic industry. working principle: ball mill machine is mainly composed of feeding part, discharging part, rotary part and driving part which includes reducer, small drive gear, electrical machine and ball mill is a kind of grinding mill used in the mineral processing, which is to further grinding the material fitness to the appropriate particle size that meets the industrial requirement after the crushing process. At present, the ball mill machine is widely used in mine, cement, silicate products, building materials and other fields. structure of ball mill

The Optimal Ball Diameter In A Mill

and with the decreased grain size, the necessary ball size also decreases for each grain size there is an optimal ball size the bigger ball in relation to the optimal one will have an excess energy, and consequently, the smaller ball mill has less energy necessary for grinding. In bothIn ball milling, the desired particle size is achieved by controlling the time, applied energy, and the size and density of the grinding media. the optimal milling occurs at a critical speed. ball mills can operate in either a wet or dry state.
