I am working in a plant with single stage grinding using a ball mill we operate the mill power at around 1400KWamp the feed size is 20mm. we use 78mm64mm steel balls. the ball mill is in closed circuit with classification cyclones. there are 3 cyclones and we operate 2 with a pressure of about 90KPa. the
Sep 01, 2013 It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters. In all cases, binary mixtures of two ball sizes 50.8 mm and 25.4 mm performed better than a mixture of the three ball sizes.
Oct 12, 2016 The size of the balls used for grinding depends on the size of the material entering the mill they should be just large enough to break the biggest lump of ore likely to be encountered. Balls of 5-in. diameter are the largest in common use, but they are only suitable for coarse feeds of 1-in. size
grinding rates The mill grinding rate through the size of interest 150 m, the circuit target P80 calculated from the plant survey data using the functional performance equation was 0.0568 t kWh. The energy specific cumulative grinding rates for the survey calculated from ball mill feed and discharge size distributions, including
Apr 27, 2019 The particle size distribution was observed after 20, 40, 60, 80, 100, 150, 200 and 300 ball mill revolutions. The energy input was calculated from the net torque corrected for the torque for the empty mill and the number of revolutions. For light ball loads the ball mill is less efficient as might be expected. As the load exceeds 1980 gm it has no influence on size reduction. The relationship between size reduction and input for optimum grinding in the ball mill
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11 . The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
Feb 20, 2017 The grinding charge in a ball mill consist of cast or forged steel balls. These balls are fed together with the feed and consequently ball mills can be in operation for months without stopping. The ball size is often in the diameter range of 20-75 mm. The biggest size is chosen when the mill is used as a primary grinding mill.
Jun 01, 2018 Dry batch milling tests were performed in a laboratory scale ball mill measuring 30.2 by 28.2cm. The mill specifications are given in Table 1. A constant ball load of 20 was maintained in all the tests with a ratio of 0.5 for binary and 0.33 for trinary ball mix. Table 1.
