### 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 mills8322 Ball mills The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter ( Figure 811) The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weightBall Mills an overview | ScienceDirect TopicsBall mill A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell A ball mill consists of a hollow cylindrical shell rotating about itshow to design a ball mill and its principle
