The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:

· 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.

The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double-toggle Jaw Crusher. Introduced in 1906, McLanahan’s Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers. On the overhead eccentric style Jaw Crusher, the moving swing jaw is suspended on the eccentric shaft with heavy-duty

Cone crushers and jaw crushers both work by compression, reducing materials by squeezing them until they break apart. The benefit that cone crushers offer over jaw crushers is their ability to output a more cubical product similar to impact crushers. Cone crushers have traditionally been used as secondary and sometimes tertiary crushing

· He outlines three simple rules behind properly sizing a jaw crusher. Rule #1: Identify maximum feed size. The size of the crusher opening directly determines the maximum feed size going into the crusher. For example, if the jaw has a 30-in. opening (gape), the maximum feed size should not exceed 80% or 24-in. If crusher feed exceeds
