ball mill dp measurement

Whereas most of the ball-milled systems usually prepared with using ball-to-powder weight ratio (W b:W p) in the range between 10:1 and 20:1, the effect W b:W p on the amorphization reaction of Al 50 Ta 50 alloy powders in a low-energy ball mill was investigated in 1991 by El-Eskandarany et al. [42] They have used 90, 30, 20, 10, and 3 g of powders to obtain W b:W p ratios of 12:1, 36:1, 54:1, 108:1, and 324:1, …

Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications)

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones

Power Measurement: the only accurate way to measure mill power is to directly measure power or torque input to the shaft. Indirect measurements are inaccurate and will underestimate mill power (Nesset, J.E. et al, Assessing the Performance and Efficiency of Fine Grinding Technologies, 38th Annual Meeting of the CMP, Canada, January 2006)
