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 …

The critical load bearing components of the Raptor cone crushers meet specifications that typically exceed what is commonly ofered in a conventional cone crusher. The major components are cast of high grade steel. The eccentric material selection provides greater certainty of a reliable surface finish over a long period of service.
HOW SIZES ARE DESIGNATED The numerical size designation of Gyratory crushers represents the feed opening and the maximum diameter of the crushing head. For example, a 60-109 Gyratory crusher has a 60-inch receiving opening and an 109-inch maximum diameter crushing head.
The function of the primary crusher is to break down the larger rocks and stones into manageable sizes, while the function of the secondary crusher is to further refine these sizes into the desired product. The secondary crusher operates by compressing the material between two surfaces, similar to the primary crusher.
