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 percentAre average Reduction ratios are up to 3 1 This machine requires one and a quarter horsepower per ton per hour of material crushed to make a 1in product The product from the roll crusher has almost no oversize The triple roll crusher is the same as above except that it has a reduction ratio of up to 5 1 Roll crushers typically have
