Crushing in Mineral Processing
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.
