  • Volume Load

    The measurement of the ball charge volume load (or filling degree) is essential to maintain the absorbed power of the mill and consequently the mill production. The most common way to evaluate the filling degree is the measurement of the free height inside the mill (vertical distance between the top of the charge and the lining in the mill axis).

  • THE GRINDING CHARGE OF ROTARY MILLS

    rotary mills. For instance, in the cement industry, the raw used to produce cement clinker as well as the cement, is obtained by determining degree the efficiency of the mill work (grinding fineness, wear of grinding media, throughput of the mill, energy which is more practical to evaluate the filling degree of the drum. For an easier

  • Optimization of mill performance by using

    The mill filling should be measured at a minimum of 3 points along the mill. Excess of slurry could also be estimated. To get rid of pulp and rocks in the charge, a mill grind-out (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining.

  • Optimization of mill performance by using

    mill absorbed power and ball filling degree. As indicated on the graph, a small variation in power could be the result of a significant variation of balls filling degree. As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or
