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.

Sand Equivalent - Pavement Interactive

Testing smaller top sized material may lower the numerical results of the test (ASTM, 2003 [1]). Aggregates recovered using the ignition furnace appear to be unsuitable for sand equivalent testing because it appears the burning process creates more material that will show up on the sand equivalent test as clay (Prowell and Carter, 2000 [3]).
