Tips for maintaining efficiency in crushing circuits
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.

What is a Jaw Crusher? – MEKA Crushing Equipment
In general, crushing is carried out in three stages, depending on the desired size of the material. Primary Crushing. This is the first stage of the crushing process. In general, the size of the feed material, which is between 800 and 1500 mm, is reduced to between 150 and 300 mm. Secondary Crushing. This is the second stage of crushing.

Crusher Reduction Ratio
Crusher 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.

Reduction Ratio/ Milling Stages Calculator
Total reduction ratio. 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.

Crushing Mineral Processing
In mineral processing, the reduction of minerals by crushing and grinding may be regarded as having one or other of two main objectives: the attainment of a size appropriate for the direct industrial application of the mineral, e.g. barytes, sand, aggregate; or the release of metallic or ore inclusions from an unwanted matrix with a view to maximum separation.

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

Crushers
Impactors produce cubic products, and they can offer high reduction ratios as long as the feed material is not too fine. This means that in certain cases it is possible to use a single impact crusher to carry out a task normally done in several crushing stages using compressing crushers (i.e., jaw, gyratory, and/or cone crushers).
