How Much Crushed Stone Do You Need? A Sure-Fire …

Crushed Stone is a man-made construction aggregate typically produced in a quarry by passing stones through a crushing machine. (Gravel, in contrast, is produced naturally). The crushed stone is typically used as a base or underlayment, for example, where the concrete of a patio will rest. It's also used for drainage and landscaping.

Crusher - Wikipedia

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.
