LAB REPORT SIZE REDUCTION.docx - Unit Operation

Abstract Size reduction is the operation carried out for reducing the size of the bigger particle into a smaller one by external forces. This reduction in size is done by using ball mill. In the experiment, the stone weighs about 300g and mix with two handhelds of grinding ball into the ball mill. The speed control knob is adjusted each at 40 rpm and 80rpm.

Ball Mill Loading - Dry Milling - Paul O. Abbe

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball
