Crusher Efficiency Calculations
Crushing & Screening Plant Assessment Example. Quarry rock of 12 in. maximum size is to be handled in a two-stage crusher plant at the rate of 70 tons per hour. The maximum size of output is to be 1½ in., and separation of materials over 1 in. size and the minus 1 in. in the output is required. Select a jaw crusher like those included in this ...
Screening Theory and Practice
Screening Theory and Practice 30. Following these calculations for the group between 12m and 14m, the "% Feed in Overs" is 10.3 ∙ 0.386 = 4.0. The "% Feed in Unders" is 6.8 ∙0 .614 = 4.0. The reconstructed feed is 4% + 4% = 8%, and the Fractional Efficiency is thus 4÷8 ∙ 100 = 50%, for both overs and unders.

Cone Crushers (Parts of a Cone Crusher) Explained
Crushing action is produced by the oscillation or throw (opening & closing) between the moving mantle liner, mounted on the cone, and the stationary concave liners mounted within the upper casing of the crusher. The mantle and concaves form the working surfaces of the crusher, as this is where the crushing action occurs.
