Gyratory Crusher Selection

Gyratory Crusher - an overview ScienceDirect Topics

Gyratory crushers were invented by Charles Brown in 1877 and developed by Gates around 1881 and were referred to as a Gates crusher. The smaller form is described as a cone crusher. The larger crushers are normally known as primary crushers as they are designed to receive run-on-mine (ROM) rocks directly from the mines.

2. GYRATORY CRUSHERS

The gyratory crusher, whether used as a primary or secondary. is essentially a gravity-type machine. Material flows vertically from top to bottom. It receives a large coarse feed, usually run-of-mine, and its product normally requires additional crushing before produc- ing the final product. The gyratory crusher is a pressure crushing device as is the jaw crusher. The crushing action itself is ...
