Apr 01, 2019 Crushing setting: Efficiency. Ideally, the reduction ratio of a jaw crusher should be 6:1. 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 per cent versus the discharge size that passes 80 per cent.

High reduction ratios of between 20:1 and 40:1 can be achieved with hammer type impact crushers. Only low reduction ratios of about 2:1 can be achieved with kinetic energy type impact crushers. 5.1.3 Crushing mechanisms and product size distributions. The crushing action of a crushing machine is described most usefully through the classification -

A 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

These are the two main causes of sub-optimal crushing performance, but losses in the reduction ratio can also be caused by selecting the wrong mantle or by having a poor chamber profile or design. Surprisingly, selecting the wrong alloy has no effect when it comes to the reduction ratio (although this will affect the life of wearable parts in ...
