Figure: Grinding media Grinding Ball Charge in Mills: According to Levenson, the optimum grinding ball charge should be r The degree of ball charge varies with in the limit of 25 and 45%.
· Traditionally, mill media wear rate is evaluated by measuring the media level in the mill, or by removing media charge and weighing it after a certain number of hours. As mentioned above, the mill was stopped after 24 h (one cycle) with a total of 24 cycles for each ceramic ball type. Grinding tests were carried out for 24 days (576 h) and ...
Let us look back at the optimal ball charge in a mill. The necessary number of balls having the definite diameter N b in a mill should be proportional to grain number N having the definite diameters which they can grind: N b ~ N. (7) The number of grains of the material with determined diameters depends on the grain size distribution.
Vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball mills for cement production when they want to design new grinding plants or a new integrated ...
