4. SIZE REDUCTION
the crusher. Size reduction in jaw crushers occurs mainly by a compression mechanism and to lower extent by impact. Fig (4.1) A Blake Type Jaw Crusher 4.4.2 Impact crushers While in a jaw crusher breaking of feed lumps takes place mainly by compression, some crushers operate on an impact principle.

The second type is known as 'high pressure grinding roll' (HPGR), in which each of the minerals or rocks are reduced in size by using compressive and interparticle pressure which is mathematically configured beforehand. Like the cone crusher, some of the most common applications that use roll crushers are ores, aggregates and unprepared rocks.
