Ball mills with high efficiency separators have been used for cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.
Regarding operations, in a ball mill, the grinding media has a higher rate of wear about the rollers and table in the VRM. In ball mills, it is essential to monitor its performance via axial testing to ascertain that the media grading is right and that there are enough top-size media to grind the mill feed materials.

Dec 08, 2009 Re how to estimate the wear rate for Ball mill. Hey Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated. More simply and quite adequate

Feb 01, 2018 No matter whether the material is inside of the mill or what size of the mill selected for the testing purpose, it was calculated that the media from the highest wear rate to the lowest was in the order of A1 A2 B1 A3 C1 B2. This implies that the testing methodology can produce comparative results hence a better understanding of the media properties can be provided and the media quality or
Aug 01, 2017 The calibration of this wear data with the measured wear profiles of the shell liner in a 5.8 m diameter industrial cement tube mill shows that the tangential damping energy defined by the linear spring-slider-damper DEM contact law is the best fitting wear model of 6 different models. The gradual update of the liner shape delivers adequate results for liners without an axial height variation, while

A cement mill (or finish mill in North American usage 1) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
The discharge grate plate of the ball mill directly affects the grinding effect of the ball mill, but the current discharge grate plate is often seriously blocked, which leads to problems such as smaller ventilation area, poor ventilation and over grinding of the ball mill, affecting the normal operation of the ball mill. Therefore, Fodamon engineer optimized and transformed the discharge ...
