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.

Kick assumed that the energy required to reduce a material in size was directly proportional to the size reduction ratio dL/L. This implies that n in eqn. (11.1) is equal to -1. If K = K K f c where K K is called Kick''s constant and f c is called the crushing strength of the material, we have: dE/dL = -K K f c L 1 which, on integration gives: E

Total reduction ratio. Source: . Crushing is done in three, or four stages while grinding is done in one, or three stages. If you don’t have many stages as shown on the app put 1 in the stages that you are not using. Calculate the total reduction ratio of a milling circuit by multiplying the reduction ratios of every stage.

As an example, suppose that it is required to make a reduction of 7:1 in two stages of crushers, one a standard gyratory and the other a fine-reduction crusher. We know from our examination of the crushing characteristics of these types that, for equal reduction ratios, the volume-reduction-ratio in the standard gyratory is considerably higher than it is in the fine reduction crusher.

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 reduction ratio for tough, high strength, damp material is restricted to the low end of the application ranges whereas a soft, low strength, dry material can be successfully crushed at the higher end of the reduction ratio.
