Jaw Crusher an overview ScienceDirect Topics
The gyratory crusher can, just like a jaw crusher, accept boulder sizes close to 1.5 m (for the largest equipment). This crusher can handle products with a Mohs hardness that is not necessarily less than 5. As is the case for jaw crushers, there is not any mutual sliding on grinding surfaces, but simply rolling of the nut on concaves.Crusher Efficiency Calculations,A jaw crusher, like 2036 in the Jaw Crusher Table here above, would be able to take the maximum 12 in. size quarry stone but it would not have the required 70 tph capacity needed. To have the needed capacity a jaw crusher like the 2042 or 2436 sizes will have to be selected overloading the secondary crusher.

Crushing Efficiency Factors Mineral Processing & Metallurgy
Toward the foregoing goal, engineers investigated the energy efficiency of crushing for less than ideal cases. In the first experiment they studied the effect of factors such as using a deep bed of particles, a situation usually present in a ball mill. The same type of slow crushing experiment described above was performed, but with a bed five or six particles deep instead of a single Influence of jaw crusher parameters on the quality of,Product quality is measured in terms of particle shape and mechanical properties. The crusher and feed parameters used are closed side setting (CSS), speed, feed rate and feed gradation. This paper presents a parameter study investigating the effect of feed and jaw crusher parameters on the quality of aggregates produced from single-stage crushing.
