Rod Mill - an overview ScienceDirect Topics

Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.

The benefits of dry machining The Engineer The Engineer

04/10/2016  Dry machining is becoming more prevalent, in milling especially. In drilling, coolant is required because the tool has prolonged exposure to the material and fluid is essential to evacuate the chips. And dry machining in turning is rare as the cutting edge is constantly in contact with the workpiece, so without some cooling, the cutting edge will eventually fail. Milling
