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, Capacity(t/h) Loading Weight of Mill Ball(t) Motor Power(KW) Main Reducer(Overall Ratio) φ2.6×10. 20.6. ≤25. 21-24. 64. 800. 6.3.

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum The main equipment for grinding construction materials are ball-tube mills, which are actively used in industry and are constantly being improved. The main issue of improvement is to reduce the power consumption of a ball-tube mill with cross-longitudinal movement of the load.

There had been a few attempts to relate their model with air flow through the mill, feed rate, feed size distribution, material filling and ball filling (Viswanathan, 1986, Zhang, 1992). Air swept ball mill model proposed by Austin et al. (1975) was validated by Apling and Ergin (1994) using the industrial scale data from a cement grinding circuit.CEMTEC offers complete turnkey projects as well as single machinery.

Firstly, the conventional ball mill parameters such as mill speed (% of critical speed), material filling ratio (Jb), ball filling ratio (fc), ball size distribution (10-20-30-40 mm, %), grindingAs a result, operating costs in a cement plant will be reduced. Ball mills used in the cement industry are inefficient grinding technologies. Any small improvement in the operation of ball mills can lead to significant annual energy savings (Tiggesbӓumker and Müller, 1983, Viswanathan and Reddy, 1992, Schnatz and Knobloch, 2000).Optimization of an industrial scale open circuit three
