  • Jaw Crusher ScienceDirect

    The closed set of an operating jaw crusher was 125 mm A continuous stream of ore was fed at the rate of 30 t/h On an average, 10% of the ore was less than the set The F 80 was 410 mm in size The crusher was initially operated at 200 rpm at a reduction ratio of 1:4, but the toggle speed was to be increased Calculate 1Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchangedCrusher Reduction Ratio Mineral Processing & MetallurgyTertiary cone crusher configurations typically work with a reduction ratio of 25:1 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 (P80)The pros and cons of cone crusher applications Quarry

    Additionally, jaw crusher feed should be prescreened using a grizzly screen prior to crushing to remove material finer than the closedside setting Setting jaw crushers Ideally, the reduction ratio of a jaw crusher should be 6to1 There are different ways to calculate reduction ratio, but the best way is something called the P80 factorIt calculated by multiplying reduction ratios of all the stages (see formula below) R/R=R/R1*R/R2*R/Rn n number of milling stages R/Rp reduction ratio of the p stage Source: formulaminerallurgy For example in a crushing circuit that consists of a jaw crusher (3/1), and a cone crusher ( 5/1), has a total reduction ratio of 15/1Calculate the Reduction Ratio and the Number of MillingJaw crushers offer reduction ratios of up to about 6:1, while cone crushers can reduce material size up to a maximum of 8:1 ratio The finer the crushing, the smaller the reduction ratio As a basic rule, jaw crushers are the primary crusher taking the mined aggregate and reducing it to a size that a cone crusher can acceptIntroduction to Rock Crushers ELRUS Aggregate Systems
