Capital Cost Of A Ball Mill Calculation Pdf. Calculate and select ball mill ball size for optimum grinding or three stages of crushing and screening a rod mill and some or all of the work of a ball mill because of the range of mill sizes available agsag milling can often be accomplished with fewer lines than in a conventional rod millball.
More DetailsRod 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.
More Details2012-5-15The ball impact energy on grain is proportional to the ball diameter to the third power 3 E K 1 d b. 3 The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding wetdry. None of the characteristics of the material being ground have any influence on K 1.
