Crusher Wikipedia

Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore ), so that pieces of different composition can be differentiated. Crushing is the process of transferring a force amplified by mechanical ... Learn More

Chipping and crushing mechanisms in orthogonal rock

Dec 01, 2016 From the physical perspective, the increase of ω decreases the chipping action but increases the crushing action in the whole rock removal process, which, in turn, increases the required cutting force. According to Eq. (44), M is proportional to the cutting force. To … Learn More
