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.

Contact2020-10-3 The reduction ratio in the size of the impact crusher is from 20 to 1. The reduction ratio in the size of the impact crusher of the type of the vertical shaft is from 4-8 to 1. The reduction ratio in the size of the vertical roller mill is from 2-2.5 to 1. The reduction ratio in the size of the hammer crusher is from 20 to 1.

ContactThe primary contributor to poor crusher performance is crushing chamber selection. If the fit between the mantle and concave in combination with the eccentric throw setting is incorrect, then the optimal reduction ratio cannot be achieved.

ContactThe reduction ratio is around 8:1 and as the product size is relatively small the feed size is limited to less than 50 mm with a nip angle between 25° and 30°. The Gyradisc crushers have head diameters from around 900 to 2100 mm. The key factor for the performance of a cone type secondary crusher is the profile of the crushing chamber or

Contact2021-4-16 A cone crusher in a secondary crushing application will typically work with a 3.5:1 to 5:1 reduction ratio. Tertiary cone crusher configurations typically work with a reduction ratio of 2.5:1 to 4:1.
