Crusher Efficiency Calculations
To have the needed capacity a jaw crusher like the 2042 or 2436 sizes will have to be selected overloading the secondary crusher. A grid chart or curve for the selected crusher shows that, for a 2½-in. setting, 54% of the material will pass a 1½-in. screen, or 46% will be retained (this is like Jaw Crusher capacity table above where 48% ...
