® Tower Mill
The tower mill is a robust, proven technology invented in the 1950s and supported by hundreds of installations in mineral concentrators worldwide The major design feature of the tower mill is a central agitator screw, the only moving machine component in contact with the slurry and steel media, which allows size reduction by attritionFor the mining industry, our semiautogenous (SAG) grinding mill uses a minimal ball charge in the range of 615 percent It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding mediaFlexible milling and grinding solutions that last |

Regrind Mills: Challenges of Scaleup Abstract
mill is filled 80% with media of the same size as final application (typically 13 mm), and agitated at 1500 RPM The mill configuration and operation discs, disc speed; media– size, media type and media filling; and mill discharge classifier – are all very similar to the full scale operation Therefore the feed particlesThe Tower mill is filled to a level with grinding media until developed power equals 80% of motor nameplate rating In a 3356kW(450hp)Tower mill, this amounts to about a 18m (6ft) depth of steel media out of a total Tower mill body height of 59 m (195 ft) Efficiency of the Tower mill depends on aTower mill and its application to fine grinding
