For this reason, state of the art cone crusher control technology in the mineral processing industry seems to be lagging; the crushing stage is overlooked because it is only a part of a mining plant, and variations in crusher performance are rarely a cause for concern, unless the implications are catastrophic (Bearman and Briggs, 1998).

At the top of each of the three raises the ore passes through a crusher before it enters the raise proper and thence falls to a pan-feeder, which feeds the belt. The belt system, fed from the three raises, is 4,991 feet long and in nine sections, each driven by a 75-horsepower, 440- volt, A. C. motor. The belt is 7-ply and 30 inches wide.

The Crusher throw is defined as the distance in the direction of compression the moving crushing surfaces/plates travel from OSS to CSS. Throw = OSS – CSS. OSS and CSS will define a crusher’s performance. The throw of the crusher is the distance that moving jaw moves in going from OSS to CSS. The capacity is a function of size and OSS.
