  • Crushing for particle shape Aggregates Manager

    Nov 17, 2014 Closing the circuit at the third or fourth stage also will help to refine particle shape because it allows for crushing at a lower reduction ratio, which improves shape. To a degree, geology dictates the type of crusher required to produce cubical aggregate products. For instance, limestone has lower abrasion

    Mar 19, 2017 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

    The Reduction Ratio is broadly defined as the ratio of the feed size to the product size in any crushing operation. It is very useful in determining what a crusher can do, or is doing, in the way of size reduction. It can also be used as a partial indior of the stresses the crusher will be subjected to during operation, an element
