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.
During the first half of the nineteenth century, mechanical crushing was not cheaply available. Stone had been crushed for applications such as Macadam road metal exclusively by hand, using the cheapest available labour, such as convicts and workhouse inmates.
