quarrying process of coarse aggregate

What is Quarrying?

Quarrying is the heavy industrial process of extracting minerals and natural resources like rocks, sand, and gravel from the surface of the earth. Also known as aggregates, quarried materials are heavily used in the building and construction industries in the construction of houses, roads, hospitals, school and other structures.

Manufactured Sand and Crushed Stones Processing

Manufactured Aggregate Processing Flow. Whether using dry, wet or semi-dry processing of manufactured aggregate, the main equipment for crushing and screening is almost the same as that of manufactured sand. Feeder→soil removal→coarse, medium and fine crushing→screening→sand making→screening→fine powder separation→online monitoring.
