Ball mill media optimization Metcom Tech

ball charge is close to 95 kg (209 lb), occupying 34 percent of the mill volume. Balls are used that represent a fully graded charge based on constant wear rate in a continuously operating mill. Slurry volume occupies the 40 percent voids volume in the 34 percent ball charge. The drive shaft is torque-metered and records once per second.

Grinding Media Charge Motion inside Mill 911 Metallurgist

Nov 07, 2016 The motion of the charge, that is the grinding media and the material undergoing grinding, within a mill is of considerable theoretical interest and practical importance, and for these reasons, has been the subject of considerable study by a number of workers, but, even so, no rigid and complete theory, covering all the aspects of the dynamics of the mill charge, has yet been produced.

EFFECTS OF GRINDING MEDIA SHAPES ON BALL MILL

media shape and mill power. The objective of this dissertation was to investigate how media shape affects grinding. Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes. Load behaviour, mill power and breakage as affected by media shapes were studied in a pilot laboratory mill. An inductive proximity probe

AMIT 135: Lesson 7 Ball Mills & Circuits Mining Mill

Ball Size Distribution. As the mill starts, grinding action and throughput increases. However, after reaching a critical speed, the mill charge clings to the inside perimeter of the mill. Under this conditions, the grinding rate is significant reduced or stopped. All mills must operate less than Critical Speed

Mill Steel Charge Volume Calculation 911 Metallurgist

Jun 19, 2015 We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.
