What's the Difference Between Ball Mill, Rod Mill and SAG Mill?
Rod mill：The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low with a light degree of over-crushing.

Overflow vs. Grate Discharge Ball Mills: What's the Difference?
Overflow ball mills are designed so that the ground product overflows out of the mill. The overflow expels the ground material because of the slurry flow out of the mill. On the other hand, grate discharge ball mills have a grate wall at the discharge end, which holds the larger particles while the fine slurry is allowed to pass through.
