Volume Load - thecementgrindingoffice.com
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 cement mill
Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately …
How Can I calculate new ball size and weight desing for ...
Mar 10, 2011 · Re: How Can I calculate new ball size and weight desing for ball mill. Dear Khan, According to my point of view:-1.Firstly look for the performance of roller press product then go for the mono chamber. 2.Is the roller press with the separator or not? 3.Mono chamber mill totally depend on the performance of the prigrinder.
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

THE GRINDING CHARGE OF ROTARY MILLS
The positive influence of the mixture of charge media is obvious in the coarse and medium grinding, and very reduced in fine grinding compartment [5]. It is preferable to replace balls with cylpebs, which have the specific surface (surface aria of one ton grinding media) with 14.5% greater than the balls. [7].
