EFFECTS OF GRINDING MEDIA SHAPES ON BALL MILL

2016614&ensp·&enspLoad behaviour, mill power and breakage as affected by media shapes were studied in a pilot laboratory mill. An inductive proximity probe, light emitting diode, phototransistor and video photographs were used to determine the load orientation in terms of toe and shoulder positions. A load beam was used to measure the torque exerted by the charge.

Accurate Scale Up IsaMill™ Advantages Isamill

20191120&ensp·&enspPower 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).
