A study of comminution in a vertical stirred ball mill.
The energy input per ton of grinding media in the stirred ball mill could be 10 times higher than for the tumbling ball mill. Although during coarse grinds the media wear was higher in the stirred ball mill than in the tumbling mill, it became less so as grinding proceeded and for a product median size of microns it was the same. Using a 5 litre batch mill, an experimental programme was designed to study the .

COMMINUTION Comminution conundrum
working. He says traditional ball mills' large grinding media consume huge amounts of energy for fine grinding and the slow rotation mill speed results in low power intensity. "Low power intensity in a ball mill cannot deliver the high mill throughput required. And the impact and abrasive stresses used in ball mills do not work well for

Comminution Testing Equipment in Mineral Processing
The first principle of comminution states that the specific energy input always equals the energy register of the product minus the energy register of the feed;. Disregard, of this principle and assignment of zero energy register to the feed, results in a distorted, interpretation of comminution results. ... Rod and ball mills from rod and ball ...
