Sep 02, 2020 The authors justify and exemplify the disintegratability procedure for geomaterials in impact crushing. The procedure distinguishes between two simultaneous processes of destruction and disintegration based on grading analysis of crushing products. The quantitative results on disintegration are obtained for metalliferous geomaterials of different texture and mineral composition. Disintegration

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 pieces of different composition can be differentiated
