How How To Find The Feed Rate For Jaw Crusher

Sep 15, 2014 To find the required areas of screen, the rate of feed of material as well as gradation of the feed must be known. The 1 -in. screen under the jaw crusher is the top deck—no deck correction factor will be necessary. Therefore, the 1 -in. screen will need to be at least 70/2.7 = 29.9 sq ft in area

    May 13, 2019 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 is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent
