Causes, effects and prevention of bearing failures

Unexpected bearing failures may force companies to pay for repairing and replacing the bearing and adjacent components, which may also sustain damage, such as housings and shafts. Bearing failures reduce a plant’s operating efficiency, increase downtime, drive cost of operations up and, in the worst cases, may injure workers. Improper lubrication

Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
