The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone Thus far we have described machines which do a portion of their work by impact but the only machine described in which this action plays an important role was the sledging roll type and particularly the Edison roll crusher and in these machines

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 The gyratory crushers

A design for a hammer crusher (Fig 2 9) essentially allows a decrease of the elevated pressure of air in the crusher discharging unit [5] The A-zone beneath the screen is communicated through the hollow ribs and openings in the body side walls with the B-zone around the shaft close to the inside surface of body side walls As a result the circulation of suspended matter in the gas between A and B zones is
