Abstract
A ring roller mill for grinding mineral clinker materials and the like comprises at least one grinding ring, at least one roller and at least one air outlet opening within the outer circumference of the grinding ring and air inlet openings on each side of the air outlet opening in the rotating direction of the grinding ring. The location of the air inlet and outlet openings, and respectively, relative to each other ensure that substantially lower flow rates occur in the mill at a certain volume flow rate compared to hitherto known mills. At the same time a more stable operation of the mill is ensured.
