Crusher Reduction Ratio Mineral Processing & Metallurgy

19/03/2017· 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 unchanged. Both of these statements are true, but the degree to which the product is affected depends to a much greater extent upon the ratio-of-volume-reduction in the crusher chamber than it does upon the actual

01/01/2016· The ore had to be crushed in a C-63 type jaw crusher 630 × 440. At a reduction ratio of 4, 18% of the ore was below the maximum size required. Determine: 1. the maximum operating capacity of the crusher, 2. the optimum speed at which it should be operated. Solution Step 1. Assume that the largest size of ore = 0.9 × gape. That is 0.560 = 0.9

Jaw Crusher an overview ScienceDirect Topics

The reduction tonnage term is dependent on the properties of the material crushed so that for a given reduction ratio, the crusher capacity will vary for different materials. Taggart attempted to compensate for this by introducing the comparative reduction tonne, Q RC, which is related to the reduction tonne by the expression (4.23) Q R = K Q RC. The comparative reduction tonne is a standard

13/05/2019· 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. The finer the closed-side setting, the greater the proportion
