The solutions are designed to protect pinions and trunnions and prevent failure in these harsh operating conditions – helping you improve reliability and safety while reducing maintenance and operating costs.
Autogenous mill and semi-autogenous mill
While AG mills operate without a ball charge, SAG mills use a grinding media charge of normally 3 % - 12 % for comminuting the feed material. The maximum feed size is between 200 mm and 500 mm. The AG/SAG mill is normally installed upstream of a tube mill operating in closed circuit with hydrocyclones.

What's the Difference Between SAG Mill and Ball Mill
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
