Double groove grinding track. In the Polysius roller mill, the double groove grinding track increases the retention time of the material on the grind ing table. This is a particular advantage in the case of mat erial with unfavourable grinding properties and a tendency not to form a stable bed.
table. The principle of double roller pair units results in a low speed difference between roller and grinding table and thus in lower wear. The ability of the grinding rollers to move verti cally enables them to automati cally compensate for wear and maintain an optimum contact between the grinding element and the material being ground.
