Jaw crushers and roller mills
Here reduction ratios of up to 1:100 are possible depending on the actual model concerned. Comminution in the jaw crusher takes place in a wedgeshaped crushing chamber between a fixed and flexible crushing jaw. In the upper suspension, the flexible crushing jaw is driven via an eccentric shaft and supported underneath by an infinitely lockable eccentric shaft. This special geometry enables ...

For primary crushing with a reduction ratio of 6 to 1. When a relatively coarse product is desired, top size usually larger than 38 mm (1 1/2") Closed Circuit Crushing System To control top size from a single crusher operating in an open circuit, material must remain in the crushing chamber until the material is reduced to top size. This results in over grinding a percentage of the product ...

Impact Crusher Reduction Ratio
Impact 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.
