Additionally, jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor.

The reduction ratio for crushing gives us important information about how large or coarse the feed can be for the crusher to handle and how fine or small the output or product will be. For example, a 6:1 reduction ratio means a crusher will break a 6" piece, or input, into 1" pieces on average. These ratios can determine which crushers will ...

The maximum feed size is approximately 8 0% of the feed opening. The open side setting is measured when the crusher is at rest. The setting is measured either top to top, or bottom to top, depending on the tooth profile of the jaw dies. The closed side setting can be calculated by deducting the stroke from the OSS.
