Analysis of the forces in a cone crusher shows that, in certain conditions, the material in the crushing chamber is subjected not only to compressive forces but also to a torque. In that case, a complex stress state appears in the material. Correspondingly, normal stress and tangential stress appear in the piece.Web

Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher's two jaws; one is fixed while the other makes an eccentric movement. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to crush all ...Web

A crusher is a machine that uses mechanical energy to break blocks of stone, concrete, or other building materials into smaller blocks of a specific grain size. They are particularly used in the mining industry to reduce the size of ore blocks and facilitate their processing. Crushers are designed to receive blocks of a maximum size.Web

The hardness of the material is typically measured in terms of compressive strength, ie the maximum force that the material can withstand before breaking. Hardness levels can range from that of concrete at 7000 psi to 50,000 psi for ores or other hard materials. The harder the material, the longer it may take to crush.Web
