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.

Theory of Breakage Involves two basic processes: • Radial cracking • Flexural rupture 14 • Rock is stronger in compression than in tension. Therefore, the easiest way to break rock is to subject it to a tensile stress greater than its ultimate strength in tension. • Rocks are heterogeneous (contain different types of rocks).
