How to Calculate and Solve for Capacity of Jaw Crusher
W = Width of Crusher. Let's solve an example; Find the closed single setting of jaw crusher when the capacity of jaw crushers is 10, the gape size is 8 and the width of crusher is 5. This implies that; C JC = Capacity of Jaw Crushers = 10. G = Gape Size = 8. W = Width of Crusher = 5. CSS = G.W / CJC. CSS = 8.5 / 10.
