A general rule of thumb for applying cone crushers is the reduction ratio. a crusher with coarse style liners would typically have a 6:1 reduction ratio. thus, with a 3⁄4” closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5 inches. reduction ratios of 8:1 may ….

Apr 03, the reduction ratio is the ratio of the crusher feed size to product size. the sizes are usually defined as the 80 % passing size of the cumulative size distribution. types of crushers. crushers are classified into three types based upon the stage of crushing they accomplish. these are (i) primary crusher, (ii) secondary crusher, and (iii.
Apr 16, a cone crusher in a secondary crushing application will typically work with a 3.5:1 to 5:1 reduction ratio. tertiary cone crusher configurations typically work with a reduction ratio of 2.5:1 to 4:1. the reduction ratio is defined as the ratio of the feed size for which 80 per cent will pass (f80), divided by the product size for which 80 per cent will pass.

Mar 02, in most cases, cone crushers provide reduction ratios (the ratio of the feed size to the crusher vs. the size of the crusher discharge) of 4-to-1 up to 6-to-1. the reduction ratio design limitations and the rated capacity (tons per hour) of the cone crusher are the most important factors to consider when designing a crushing circuit - and.
