Steel - Bessemer steel: Bulk steel production was made possible by Henry Bessemer in 1855, when he obtained British patents for a pneumatic steelmaking process. (A similar process is said to have been used in the United States by William Kelly in 1851, but it was not patented until 1857.)
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.

To make chalk, limestone is first quarried, generally by an open pit quarry method. Next, the limestone must be crushed. Primary crushing, such as in a jaw crusher, breaks down large boulders; secondary crushing pulverizes smaller chunks into pebbles.
PRIMARY CRUSHING: MOBILE JAW CRUSHERS. Jaw crushers operate according to the principle of pressure crushing. The raw feed is crushed in the wedge-shaped pit created between the fixed crusher jaw, and the crusher jaw articulated on an eccentric shaft.
