Optimization of mill performance by using online ball and pulp measurements In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74%, the product becomes coarser again. At this

The present study is taken to control the particle size distribution and reduce the specific energy consumption in an industrial ball mill. A batch mill of 2.21m diameter and 2.43m is used for grinding silica from average size of 3mm to 100% below 80 microns.

How to Optimise the Speed of the Ball Mill The speed of a Ball Mill is in measured in revolutions per minute (rpm) of its drum.To measure this, you need a stopwatch (preferably that rings!) and a thick felt pen. Mark a bold line lengthwise on the outside of the drum.

19/10/2007· The mill was running at a speed of 75% of critical (58.8 rpm) with a ball load of 20% of mill volume. Download : Download full-size image Fig. 4. Experimental load position measured by the inactive proximity sensor during 7 mill revolutions. (a) Bevel liner, (b) bevel

The present study is taken to control the particle size distribution and reduce the specific energy consumption in an industrial ball mill. A batch mill of 2.21m diameter and 2.43m is used for grinding silica from average size of 3mm to 100% below 80 microns.

31/7/2014· Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5-8 mm range) improves grinding energy efficiency up to 50

Mill speed influences the power draw in two ways: on the one hand, mill power is the lineal product of the mill rotational speed and the torque applied, so there is a lineal dependence; on the other hand, the centreof gravity of the charge is shifted withspeed, creating a non-lineal dependence.
