However, despite a generally good performance of vertical roller mills used for grinding of cement and related products the vertical roller mill is still inferior to the ball mill in terms of sensitivity to variations of mill feed quality (fineness) and mill feed rate. Product quality
steel balls in a ball mill, or large lumps of ore in an autogenous mill or a mixture in a semi-autogenous mill, as well as the slurry that makes up the operating charge. Let Jt be the fraction of the mill volume that is occupied by the total charge, Jb the fraction of the mill volume that is occupied by steel balls and E the voidage of the balls
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 overloading the mill is an additional factor. A direct measurement of the ball level in the mill.
