Slurry density effects on ball milling in a laboratory dec 01 1989nbsp018332the effect of slurry density on the dynamics and grinding behavior of a batch ball mill was studied using quartz as a test material it was found that slurry density determined the distribution of solid charge in the mill with migration of particles from the tumbling zone to the mill periphery as solid concentration
Optimization of mill performance by using online ball and pulp measurements by b clermont and b de haas synopsis ball mills are usually the largest consumers of energy within a mineral concentrator comminution is responsible for 50 of the total mineral processing cost in todays global markets expanding mining groups are trying
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
The geometry of a mill with conical ends is shown in figure 86 the total volume inside the mill is given by vm 4 d2 ml 1 2lc l l 1 dtdm 3 1 dtdm 816 the density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill
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 ball charge and hence the volume of the voids between the balls in the mill is known and we are then able to calculate the factor volume pulpvolume voids between the balls repeatability the repeatability of the pilot plant was investigated in the past with 2 repeat test runs with the 082 x 1 m grate discharge mill in open
