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 ...
General Kinematics STM-SCREEN™ Two-Mass Vibratory Screens utilize GK's proven Two-Mass, natural frequency drive design.This design is load responsive and capable of longer material retention times to work the material more. This means you can get more screening accomplished in the same footprint as your old brute force screens.
