Mill’s performance, monitored based on vision, acoustic, inertial data and motor signals can be optimized by the input of grinding media, changing of the slurry density (by adding process water), adjusting of the speed (expressed as a % of the critical speed) or increasing/decreasing of the mill’s load. All the mentioned adjustments influence the throughput and PSD of the product. Some of

Rod mills speed should be limited to a maximum of 70% of critical speed and preferably should be in the 60 to 68 percent critical speed range. Pebble mills are usually run at speeds between 75 and 85 percent of critical speed. Ball Mill Critical Speed . The black dot in the imagery above represents the centre of gravity of the charge.

The CRITICAL SPEED is the maximum revolutions per minute that the mill can revolve and still maintain performance. Naturally, the opposite is true as well, if the speed, is too slow the material will cascade too soon losing both impact energy and grinding motion. The size of the grinding media and the speed of the mill will have to be balanced
