AMIT 135: Lesson 5 Crushing – Mining Mill Operator Training

Normally the size reduction by crushing is of limited importance besides the top size of the product going to grinding. This means that the number of crushing stages can be reduced depending on the feed size accepted by primary grinding stage.


All operations in size reduction, both crush ing and grinding are of course determ ined by the feed . characteristics of the minerals (rock/ore) moving into the circuit.


Size reduction by crushing has a size lim itation for the final products. If we requir e further reduction, say below 5-20 mm, we have to use the processes of grinding.
