— appropriate portions of water and a binding agent like bitumen or cement. Crushed – rock aggregates are produced in quarries. In areas where natural sand and gravel aggregate deposits are insufficient to handle local demand, larger quarry rocks are processed in an impact crusher to create crushed-rock aggregate.
Crushing 'Comminution' is the term used to define the process that reduces materials (especially mined ore).It is the action of reducing a material to minute fragments or particles.The process is typically achieved in mining operations through stages of crushing and milling. In the past, mining activities were arduous and labour intensive.
