crushing, selectively crushing the material. Already-to-size particles pass through the crusher without further reduction minimising the generation of 'fines'. The power requirement is in direct proportion to the speed and work performed giving efficient power usage resulting in lower operating cost. More selective crushing reduces
Roll Crusher an overview ScienceDirect Topics
Maximum Diameter of Rock Gripped in Crushing Rolls Relative to Roll Diameter Unless very large diameter rolls are used, the angle of nip limits the reduction ratio of the crusher, and since reduction ratios greater than 4:1 are rare, a flowsheet may require coarse crushing rolls to be followed by fine rolls.
First choice for HPGR technology and service
2016-5-4 For ideal inter-particle compression, grinding the feed particle sizes should be smaller than the operating gap between the rolls. In actual applications, the top size of a feed distribution can contain particles of up to about 70% greater than the operating gap.

Crushing Vs Grinding Minerallurgy
Crushing is usually a dry process, while milling is performed with water. The advantage of wet milling is the lower energy input compared to dry milling. Additionally, some chemical reagents can be used to minimize the energy consumption of grinding, because grinding energy is minimum at pH of the point of zero electrical charges of the
