Crusher Reduction Ratio - Mineral Processing & Metallurgy

2016-1-12 · 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.

Tips for maintaining efficiency in crushing circuits - Quarry

2019-4-1 · 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.

Comminution - Mineral Processing & Metallurgy

2016-11-9 · In this case the crushing coefficient is defined as the energy corresponding to a given reduction ratio, and so corresponds to WR above. In order to obtain such a “crushing coefficient”, Carey and Stairmand made use of the similarity in frequency distributions of crushed products and so developed the principle of “associated energy”.

CPE: Lesson 13. Principle of Size Reduction

For example, coarse crushers have size reduction ratios of below 8:1, while fine grinders may present ratios as high as 100:1. However, large reduction ratios, such as those obtained when dividing relatively large solid lumps to ultra-fine powders, are normally attained by several stages using diverse crushing and grinding machines.
