The Mohs scale of mineral hardness is frequently used to specify hardness. A hammer mill is typically good for grinding softer materials with Mohs hardness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable

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).
