Ball Mill Media Charge Pattern Get Price And Support We would be glad to have feedback from you Drop us a line whether it is a comment a question a work proposition or just a hello You can use either the form below or the contact details on the right
Sep 01 2016 · The increased mill charge load will lead to an increase in mill power draw The onset point of overfilling an AGSAG mill can be indicated when the mill power draw exceeds the safe operation power threshold In a ball mill however the mill power draw is dominated by ball media charge volume for a given mill rotational speed
For overflow ball mills the charge should not exceed 45 of the mill volume For grate discharge mills the charge should occupy about 50 of the mill volume Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge He and the radius of the mill R ie
the charge However the general pattern of the motion of the media can be simulated by discrete element methods which provide valuable information about the dynamic conditions inside the mill Some of the terms that are often used to describe the motion of the media in a tumbling mill are shown in Figure 82 812 Critical speed of rotation The
Common types of grinding mills include Ball Mills and Rod Mills This includes all rotating mills with heavy grinding media loads This article focuses on ball and rod mills excluding SAG and AG mills Although their concepts are very similar they are not discussed here Photographs of a glass ended laboratory ball mill show action of ball mass within the mill The action of other grinding
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience Different manufacturers use different methods and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent It is especially difficult to teach mill
