If a crusher operates at varying cavity levels throughout the shift, the result will be an inconsistent product shape and inconsistent production rate. Operating a cone crusher at a low cavity level (half cavity) will result in a significantly coarser product gradation, and this low cavity level will also produce more flat and elongated product ...

In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of the crusher, while the other is an eccentric shaft that drives both toggle ...

For instance, if the final size of your product only needs to be between 4 inches and 6 inches, a primary jaw or impact crusher can accomplish your goals. However, you will likely require a much finer product, and that means incorporating up to three—or even four—stations with a variety of crusher types. 1. Primary Crushing

Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).
