As stone passes through a crusher, the reduction in size may be expressed as reduction ratio. The reduction ratio is the ratio of crusher feed size to product size. The sizes are usually defined as the 80% passing size of the cumulative size distribution. For jaw crusher, the ratio can be estimated by the gape. CHAPTER 14. AGGREGATE PRODUCTION
