A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding Denmark (trade named Cemax Mill). Horomill is suitable for grinding raw meal, cement and minerals, whereas Cemax Mill is mainly for cement grinding. The mill can be used for pre-grinding and finish grinding. This mill-system claims to have advantages of ball mill, roller mill and roller press in terms of reliability and energy savings.
