Crusher, also known as stone crusher, is an indispensable mining machinery in the production of artificial sand and gravel.
Crushing operations are often divided into coarse crushing, medium crushing and fine crushing according to the size of the feeding and discharging particles. Coarse crushing equipment can crush stones with a compressive strength of up to 350Mpa. Medium crushing can crush stones with a compressive strength of less than 200Mpa and a calcium content of more than 40%. Fine crushing equipment generally uses grinding and sand production equipment.
The role of crusher in ore crushing
As the main crushing product of mining machinery, the crusher plays an important role in the mineral processing process. Ore crushing is the process of crushing large pieces of ore with the help of external forces to overcome the internal forces, so that the ore is broken and the particle size is gradually reduced. In the mineral processing process, ore crushing is usually divided into two stages: crushing (coarse-grained stage) and grinding (fine-grained stage). Crushing equipment is an indispensable mining machinery and a good way to solve the depletion of sand resources.
