Comminution Wikipedia

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth''s crust.

OPTIMIZATION OF COMMINUTION CIRCUIT THROUGHPUT ... …

Overgrinding was primarily caused by two effects: (1) The hydrocyclones used to close the circuit and remove fullyground particles from the circuit were preferentially returning highdensity ore particles to the secondary mills for regrinding even after they were already ground to pass the desired product size, and (2) The primary grinding ...

Comminution Circuits for Gold Ore Processing ScienceDirect

Such a circuit can counteract the effects of harder ore, coarser ore, decrease the size of SAG mill required, or rectify poor throughput due to an undersized SAG circuit. Notably, harder ore often presents itself to the SAG circuit as coarser than softer ore—less comminution is produced in blasting and primary crushing, and therefore the ...
