aug 30, 2019 1 calculation of ball mill capacity. the production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. there are many factors affecting the production capacity of the ball mill, in addition to the nature of the material grain size, hardness, density, temperature and humidity, the degree of,continuous ball mill continuous type ball mill,continuous ball mill with low energy consumption. the continuous grinding mode requires higher temperature of the barrel. such temperature condition and dynamic pulping mode reduce the viscosity of the material after grinding, reduce water consumption and material evaporation, and reduce power consumption.

this ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. due to the difference of its slurry discharging method, it is divided to two types grid type ball mill and overflow type ball mill.,used ballmills for sale grinding mills crushers,inventory id 6c-hm02. unused flsmidth 22 x 416 dual pinion regrind ball mill with 2 abb 5,500 kw 7,375 hp drives for total power of 11,000 kw 14,750 hp
