When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of
Rod mills commonly use steel rods with a diameter of 50-100mm as the grinding medium, while ball mills use steel balls as the grinding medium. The difference in the grinding body is the main...
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.
Product Structure. Rod Mill principle. (1) Rod mill is usually selected in order to prevent over-grinding in gravity or magnetic separation plant of tungsten tin and other rare metals mine; (2) In two stages grinding, the capacity of rod mill in the first stage grinding is larger than that of ball mill; (3) In some cases, rod mill can replace short

Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill.
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency 
The rod mill can grind any ore rock from ≤25 mm into 0.075 mm.Capacity : from 0.62 t/h to 180 t/h flexible.Please click for full details. Rod mill is grinding equipment, which is similar to ball mill. The difference between rod mill and ball mill is that the former is
Ball Mill Is The Key Milling Equipment After Material Has Been Crushed 1. The ball mill can grind various materials and produce ore pulp. 2. It can be divided into wet and dry grinding method. Usually we adopt the latter. 3. It is full of high efficiency, less friction
