The commercially viable and industry accepted alternate is a grate discharge trunnion supported mill or a grate discharge shell supported mill using pulp lifters. The only way to eliminate the problem of flow-back and carry-over of slurry and pebbles is by optimizing the design of the discharge arrangement.
Outokumpu can provide you with high-aspect or low-aspect AG/SAG mills to meet any milling requirement.

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 ...

1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.
FIG. 1 illustrates a shell supported grinding mill 1 according to one exemplary embodiment of the invention. The grinding mill 1 may be any type of mill suitable for grinding, such as a Ball mill, an Autogenous (AG) mill, a Semi-Autogenous (SAG) mill, a Pebble mill or a Rod mill, and is mainly used for grinding ore material.
SAG Mill Horsepower — Drive Power. When the normal operating horsepower has been defined. It can be related to a design drive horsepower. If the mill operating horsepower is defined as "net at the shell", then the appropriate losses for trunnion bearings, pinionshaft bearings, and gearing must be accounted for to compute …
