(Mining mill) Autogenous mill
The autogenous mill can directly add the raw ore or the uncrushed ore in the quarry to the autogenous mill. It can grind the material to0.074mm at one time, which accounts for more than 20% ~ 50% of the total product. The crushing ratio can reach 4000 ~ 5000, which is more thanten times higher than the efficiency of the ball mill and the rod mill.

What is a Semi-Autogenous Mill?
A semi-autogenous mill is a type of grinding mill that uses grinding balls and ore or rock fragments as grinding media. The grinding is done by the impact of the rocks or ore particles on themselves or on the grinding media, thus breaking the ore into smaller particles. Semi-autogenous mills use a minimal ball charge of 6 to 15%.
