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.

primary gyratory crusher reduction ratio
Primary Crusher Reduction. Primary Gyratory Crusher Reduction Ratio. The gyratory crushers crush to reduce the sie by a maximum of about one-tenth its sie. Usually metallurgical operations require greater sie reduction hence the products from the primary crushers are conveyed to secondary or cone crushers where further reduction in sie takes place.
