In a vertical shaft impact crusher, the aggregate feed is introduced into a shoe or pump spinning on a vertical axis. The aggregate feed is thrown centrifugalLY against a series of anvils, pockets of aggregate particles (i.e., autogenous), or a combination thereof. Vertical shaft impact crushers produce a small reduction ratio and arc often used for crushing tines.
The technical literature is replete with descriptions of and data on shaft sinking equipment, methods and costs. The subject of shaft sinking has been discussed at some length in an earlier Bureau of Mines bulletin. A number of shaft-sinking operations are described in detail in the series of information circulars on mining methods and costs, to some of which reference will be made later.
