The tower mill is a robust, proven technology invented in the 1950's 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 attrition.

Introduction. The TowerMill® was developed in Japan in the 1950s, by the Tower Mill Corporation, for applications in fine and ultrafine grinding, and it was the first vertical mill used in the mineral industry (Stief et al., 1987).The Vertimill™, manufactured by has basically the same principle of operation and was introduced in the 1990's (Kalra, 1999).
