Lab Report 1 and 2: PRACTICAL 1 : BALL MILLING

2013-12-28  Ball Mill is the equipment to be used for size reduction. It is a kind of grinder used for intermediate or fine grinding. Ball mill is a metal cylinder which rotates about its horizontal axis. The coarse sugar charged along with the metal balls breaks to fine powder by impact of metal balls.

Ball Mills an overview ScienceDirect Topics

8.3.2.2 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.

A Study on the Effects of Ball Defects on the Fatigue Life

Hybrid ball bearings using silicon nitride ceramic balls with steel rings are increasingly being used in space mechanism applications due to their high wear resistance and long rolling contact fatigue life. However, qualitative and quantitative reports of the effects of ball defects that cause early fatigue failure are rare. We report on our approach to study these effects.
