Jan 12, 2016For a given ratio-of-reduction, the type of crusher with a flared crushing chamber will usually deliver a cleaner product than any of the older types; conversely, more reduction can be performed in the machine without creating excessive fines. The facts outlined in the foregoing paragraph have an important bearing on crushing plant design.

ContactOct 03, 2020The reduction ratio of the crusher size is simply calculated as the ratio of the particle size of the raw material and particle size of the crushing.

ContactMay 13, 2019Ideally, 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.

Contact• Much more versatile than smooth roll crusher • Best example Break and reduction rolls of wheat milling • Disintegrators are toothed roll crushers in which the corrugated rolls are rotating at different speeds • Size reduction is by compression, impact and shear and not by compression alone, as in the case of smooth roll crushers

ContactMar 28, 2021The general formula to calculate the reduction ratio is as defined Df/dp. Df is the feed size. dp the product size. We can use a cut size as the size through which 50% (masse) of the material passed, d50, or we can use d75, d80, etc.

ContactJaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The primary operating variable available on a crusher is the set and on jaw and gyratory the open-side set (OSS) is specified. This reflects the fact that considerable

ContactApr 24, 2015ROLL CRUSHER Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1.

ContactJan 12, 2016Crusher 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 unchanged.

ContactThe difference between a conventional impactor and a VSI of the Barmac type is that the latter offers lower operating costs, but its reduction ratio is lower also. In a Barmac VSI, the material undergoes an intense rock-on-rock crushing process. In the other crushers, most of the reduction is done by the impact of stone against metal.

ContactA 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 be possible in certain coarse crushing applications.
