Read MoreA 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.

Read MoreCone crushers are critical pieces for aggregate production, mineral processing operations, and recycling applications. They're typically a secondary or tertiary rock crusher and produce a fine or medium-sized aggregate material. Since cone crushers have a large feed opening and small discharge sizes, this type of aggregate equipment has a high crushing ratio, making them quite efficient on ...

Read More6/1/2017· The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa-We) W2= Weigh of aggregates passing through 2.36mm IS sieve.
