Comminution | Multotec
The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials. The process is most often used in the field of mining and / or mineral processing, where mineral ore is broken down into small particles, by hammer, roller / vibrating disc mills and jaw, gyratory and cone crushers.

Crushing | CTP
Industrial crushers reduce the material from very large pieces or blocks to around 10 mm. They operate on different principles, depending on the characteristics of the material (mechanical resistance, abrasiveness, humidity): by compression/crushing (jaw crusher, rotary crusher, cone crusher or roller crusher) or by impact/percussion (impact crusher or hammer mill).
