In the ball mill, the motion of charge is a complex system, especially under wet grinding. It is difficult to measure the charge physical quantities and hard to validate the correctness of charge motion simulation. To this end, an instrumented ball which is capable of measuring the charge physical quantities was designed.

After experiencing this "listening" over time you can determine these different sounds such as ball on ball, ball on ore (toe or center of charge), and ball on lifter/liner impacts. Over the years our philosophy has changed, with the one exception of Africa where mills were commonly running at 90% of critical speed to be gentle with incompetent ...

instrumented grinding ball offers the ability to qualitatively observe and optimize the milling environment. An instrumented load cell package that can measure the force of impacts inside the grinding chamber of a mill is developed here. The signal from the instrumented load cell package is interpreted in terms of a histogram termed as an

Tumbling mills have been widely implemented in many industrial sectors for the grinding of bulk materials. They have been used for decades in the production of fines and in the final stages of ore comminution, where optimal levels for the enrichment particles' sizes are obtained. Even though these ubiquitous machines of relatively simple construction have been …

Stirred mills were first introduced in the 1950`s as an alternative to ball mills in a regrind application. Since then they have been used to grind a range of materials from limestone to coal to sulfide concentrates. A laboratory tower mill was used to investigate the effect of some variables on the power requirements of a plant mill.
