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 ...

The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.
The plus ½" mill product was crushed in a cone crusher and returned to the mill feed along with the minus ½" plus 4 or 6 mesh fraction. Tests were run with a short mill, inside length of 26-3/8″, or diameter-to-length ratio of 2.50 to 1. The same mill was then lengthened to 48-3/8″, diameter-to-length ratio of 1.36 to 1.

gear driven mill, the motor speed is a function of the mill speed ⌽ RPM, and the gear ratio of the mill bull gear and the drive pinion. Case study No 1: Changing pinion on a fixed speed mill A common way of changing the speed of a mill that is driven by a fixed-speed motor is to change the pinion to a new design with an additional tooth.
Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These
