Engineering. Mechanical Engineering. A ball mill is to grind 250 tons/day of calcite having a specific surface of 90.34 cm²/g. No recrushing of material is to be done. Overall energy effectiveness of the ball mill is 7.5%. Rittinger's number of calcite is 1053 cm²/ft-lbf. Assuming the calcite have densities=2 g/cm³ and are perfect spheres ...

Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. The variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications. Cooling, heating & cryogenic grinding.

Small Ball Mill. Feeding size: ≤25mm. Capacity: 0.65-25t/h. Motor power: 18.5-380kW. Applications: It can be used in production industries such as cement, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation and glass ceramics, as well as schools, scientific research units and laboratories.

The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding. That is, for every incremental increase in circulating load of ...

5. The size of the ball mill is large, and it is necessary to carry out lifting work during the process of replacing the ball mill liner. The hoisting ball mill liner is the responsibility of the hoist. The lifting process requires attention to the operation of the wire rope and the hook. 6.
