Crusher Efficiency Calculations - 911 Metallurgist

15/09/2014  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% passes a 1½ in. screen). The 46% of 70 tph gives the 32 tph fed to the secondary crusher shown in Figure below as a roll crusher.
