How Is Granite Extracted? Sciencing

Apr 24, 2017· The reaction of the decaying material releases large amounts of heat, melting the rocks around it. As geological events happen (such as the moving of plates or the buildup of pressure from the heat), the molten rocks are pushed toward the surface. As the rock gets closer to the surface, it also cools, creating internal igneous rocks.

Crusher Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, 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 pieces of different composition can be differentiated.
