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.

Ball Mill
Ball mills tumble iron or steel balls with the ore The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills dry basis is typically 75 vol ore and 25 steel The ball mill is operated in closed circuit with a particle size measurement device and size control cyclones.
