Nowadays most semi-autogenous mills incorporate a sensor that measures the overall noise level generated by the mill in motion. In some industrial plants, this signal is used as control variable to limit the mill operating speed and/or the feed flow rate. To this effect, it is important to be able to discriminate between the noise level ...
Other articles where autogenous mill is discussed: mineral processing: Grinding: Autogenous mills operate without grinding bodies; instead, the coarser part of the ore simply grinds itself and the smaller fractions. To semiautogenous mills (which have become widespread), 5 to 10 percent grinding bodies (usually metal spheres) are added.

Autogenous mill is a type of grinding equipment that crushes material by mutual impact, grinding and peeling effect among material grains. In 1880, cylindrical grinding mill was invented. In 1899, it was used at a gold mine. Since then, it was discovered that autogenous grinding of ore is possible. In 1932, the world's first Φ7.3 m × 0.9 m ...

Fig. 1 - Semiautogenous mill rail liner Whether the mill is to be fully autogenous (FAG) or semiautogenous (SAG), there are some basic design concepts to remember. Abrasive slurry racing or "washing" on the mill shell cylinder and ends must not be allowed . Catas trophic damage to structural elements can result.
Close circuiting autogenous and semi-autogenous mills is an energy efficient way of grinding and a number of operations have utilised this in the design of their comminution circuits. Owing to the large flow of slurry through the mill that results from operating this way the grates and pulp lifters have to be designed to cope. However, the literature has …
