Rock Crushing Process in Mining

Let’s follow a rock through a crushing cycle to see what variables will have to be controlled. First the rock will enter the crushing chamber and drop as far as the angle of the crushing surface will allow it to. The crusher “breaks it and the fine material

Crusher Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust. 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, so that pieces of different composition can be differentiated. Crushing is the process of transferring a force amplified

Towards realistic simulations of the impact

20-03-2021 For a rock crushing strength of 20 MPa, the maximum penetration depths for bulky and flaky rocks with a rock crushing strength of 20 MPa are 0.53 m and 0.65 m, respectively. Based on Eqs.,, the minimum required thickness are 1.06 m and 1.30 m for bulky and flaky rocks, respectively.

crushing and pulverizing the solid

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust. 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 is crushed due to squeezing and grinding inside the crushing chamber.

Towards realistic simulations of the impact

20-03-2021 Flaky rocks are angular and restrict rotation, enabling force chains to sustain high loads. This implies that rounded rocks with high rock crushing strength may be more favourable to attenuate loads. b) For a rock crushing strength of 20 MPa (lowest strength simulated in this study), rocks that are more angular crush more easily.
