Effect of media size in stirred ball mill grinding of

01/12/1986  In stirred ball mill grinding using grinding media of uniform size, the particles that have a Db/Dp value less than the critical value will not be broken as readily. Unfortunately, the value of p is not known for the present system. However, it has been shown in Fig. 4 that when using 6.4 mm balls, the breakage rate passes through a maximum at a Db/Dp value of approximately 20. As has already been discussed, the breakage rate increases with increasing particle size

Ball Mill Loading - Dry Milling - Paul O. Abbe

Charging a Dry Mill – The general operation of a grinding mill is to have the product impacted between the balls as they tumble. If there are insufficient solids in the mill then the media will strike itself and generate excessive media wear. If too much product then the solid may buffer the impact too much. As with most of the independent variable in ball milling it is best to do some ...
