We would like to show you a description here but the site won't allow us.

To generate very fine fractions i.e., product sizes below 2 mm, modern roll crushers (high pressure grinding rolls) or vertical shaft impactors are recommended. …

Benchmarking energy efficiency requires three measurements: comminution power, rock throughput and the resulting size reduction. The first two measurements are fairly objective, however, the …

The crusher's chamber is a good place to start. Over the life of a mine, the production goals of a single crushing stage can change significantly. Ore properties can also show a high degree of variability. If the crusher wear parts are not customized to these changing conditions, it can produce less and require more costly maintenance.
