6. PREDICTABLE SCALE UP – Scale up from small to large mills is very predictable. Ball milling is one of the few unit operations that actual improve in performance and efficiency with increasing size. The ABBE Slice Mill is the same as the product mill and can replicate all mill operating parameters but with very little product.

This is the raw mill not the finish mill. So Wi should be 11 and density of 2.67 as normal kiln feed. I used d80 of 3500 micron to be on safe side and got max ball dia. of 41 mm (use 50 mm steel balls).

Ball mill
• Weight of the balls: With a heavy discharge of balls,we get a fine product.We can increase the weight of the charge by increasing the number of balls or by using a ball material of high density • Speed & rotation of Ball mill: low speeds,the balls simply roll over one another and little grinding is obtained while at very high speeds the

THE BULK WEIGHT OF GRINDING BALLS
The bulk weigh of the grinding balls is necessary to understand the grinding balls mass in the cube, the grinding balls mass loaded into the mill, the prevention of mill overloading with grinding balls, etc. These data often used in operational management of grinding process. Consider a definition technique the bulk weight of new grinding balls.

Practical 1 : Ball Milling | TF Lab 1
Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is used in breakage of larger rocks. SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to ball mill but has large diameter and short length.

Ball Mills
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Ball Mill Loading
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 charge for total of 23%
