2013-9-1 gives the optimum composition of 40% 50.8 mm ball and 60% 25.4 mm balls for a 1 m diameter mill, and 27% 50.8 mm and 73% 25.4 mm for a 2 m diameter mill when grinding from a 90% passing 9.5 mm feed to an 80% passing 150 μm product. The portion of 50.8 mm balls decreases as the feed size or the product size decreases. However, this can be a good starting point for determining

2009-8-26 The pulp weight in the mill is obtained by subtracting the mill weight during the test from the empty mill weight, including the ball charge, at the start of the test. The pulp volume of the pulp in the mill is then calculated using the mill discharge density (before dilution) obtained during the sampling.

2019-1-17 With extension of ball-milling time, the temperature for maximum degradation rate reduced to 369.3 °C, 367.2 °C and 362.4 °C for BMC-15, 45 and 120 (Fig. S3a). However, the weight loss at each maximum DTG temperature showed a gradual increase (Fig. S3b), confirming the loss of stability after ball-milling treatments.
