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.

How to Analyze Gear Failures

11-02-2021The gear geometry data collected earlier aids in estimating tooth contact stress, bending stress, lubricant film thickness, and gear tooth contact temperature based on transmitted loads for each gear. These values are calculated according to American Gear Manufacturers Association standards such as ANSI/AGMA 2001-B88 for spur and helical gears.

Innovation in open gear lubrication

Correct lubricant selection and application play a vital role in addressing the problem.Open-gear drives of kilns and ball mills are often exposed to harsh operating conditions. While considerable advances have been made in terms of the design and manufacturer of the drives, tooth flank damage remains and issue due to excessive wear or material fatigue.

The Three Mistakes of Bearing Lubrication

19-05-2016Mistake 2 – Over and under Lubrication. The second mistake we must avoid is adding too much, or not enough grease. Too much grease builds pressure, pushing the rolling elements through the fluid film and against the outer race. The bearing now has to work much harder to push the rolling elements through a mud bog of grease.

Galling

Galling is a common problem in sheet metal forming, bearings and pistons in engines, hydraulic cylinders, air motors, and many other industrial operations. Galling is distinct from gouging or scratching in that it involves the visible transfer of material as it is adhesively pulled ( mechanically spalled ) from one surface, leaving it stuck to the other in the form of a raised lump (gall).
