Crushing

Crushing is the first stage of fragmentation. This task is carried out in two or three stages (primary, secondary and tertiary crushing), predominantly in dry sorting.

Industrial crushers reduce the materials from very large pieces or blocks of up to around 10mm. They operate on different principles according to the characteristics of the material (mechanical resistance, abrasiveness, moisture content): by compression/crushing (jaw, gyratory, conical or roll crushers) or by shock/percussion (impact or hammer crusher).

Type	Materials	Particle size In (d100)	Particle Size Out (d50)	Capacity max
Hammer	Low abrasion materials	0 - 125 mm	Grilles de 80 mm à 4 mm	1 t/h
Jaw	Hard and abrasive materials	0 - 200 mm	0 - 30 mm	1 t/h
		0 - 80 mm	0 - 10 mm	100-200 kh/h
		0 - 50 mm	0 - 2 mm	100 kg/h
