rod mills have become niche comminution devices since about 30 years ago. because of mechanical limitations on rod length and the need to have an aspect ratio for the mill that avoids tangling a potentially deadly failure for those tasked with rectifying the problem rod mills have a maximum installed power of about 2.5 mw

the reduction ratio r in rod mills varies from 2 and 20 depending on the characteristics of the ore the usual reduction ratio is about 8 according to bond 4 the reduction ratio is a function of length and diameter of the mill the optimum reduction ratio r ro can be written as. how to calculate size reduction ratio
crushers, grinding mills and pulverizers are types of grinding equipment to transform or reduce a coarse material such as stone, coal, or slag into a smaller, finer material. kicks law states that the energy is proportional to the size reduction ratio. the equation for kicks law can be written as e there are many different
wire rod, in fact if the section of the entry round bar is not constant, the low section reduction ratio in the finishing block may not be able to correct such shape defect, resulting in a poor quality which is not acceptable especially if the wire rod will be processed in a drawing lines
the reduction ratio, r, in rod mills varies from 2 and 20 depending on the characteristics of the ore.the usual reduction ratio is about 8. according to bond 4, the reduction ratio is a function of length and diameter of the mill. the optimum reduction ratio, r ro, can be written as. amit 135 lesson 8 rod mills mining mill operator training
bond proposes an optimum reduction ratio for rod mills bon 61b, p. 545. if the real ratio deviates, then w i must be multiplied by a correction coefficient equation 26 in bon 61b,p. 545. for a ball mill, if the reduction ratio becomes less than 3 target grinding of concentrates, the energy index w i must be multiplied by a given
