Praticle Size Reduction in the Ball Mill: Drug Development ...

2008-10-20  The size distribution produced by the ball milling of various crystalline and non-crystalline materials, showed that initially there was a fairly even distribution over the size range up to 355μm. However, as milling proceeded two distribution modes developed; one at about 90μm (the persistent mode) and one at about 250μm (the transitory mode).

2018-6-1  Fig. 8 shows that the small 10 mm ball size is superior in generating more material in the fines size class, from both feed sizes used. If an objective function was to maximize the production of fines e.g. in the cement industry, the A.R shows that use of smaller ball sizes would give superior results.

2012-9-5  4.1 Size reduction of solid foods 4.1.1 Theory In all types of size reduction there are three types of force used to reduce the size of foods: 1. compression forces 2. impact forces 3. shearing (or attrition) forces. In most size reduction equipment, all three forces are present, but often one is more important than the others.
