Rod Mill Vs Ball Mill Comparative Analysis Of :
ball mill machine has always been the main grinding equipment in wet cement production. In the early years, the rod mill was first used in cement raw meal grinding, which increased the output of the grinding section by 31%, saved energy by 27%, and reduced the consumption of grinding media by 47%.rod mills are very similar to ball mills, except they use long rods for grinding media. the rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. rod mills accept feed up to about mm ball mills and rod mills are both excellent mining machines for grinding ores into fine powders and particles. however there are some advantages to using rod mills rather than ball mills for larger mining projects including greater efficiency, better grinding performance and lower energy costs.

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 moisture. As such, when the product is sticky, rod mills are preferred over ball mills.steel rod is usually used as grinding medium in rod mill, while steel ball is used as grinding medium in ball mill. the steel balls are in point contact with each other, and the steel rod of rod mill is in line contact with each other, so their working features are obviously different.
