Cement ball mills can be divided according to discharge method grate ball mills and overflow mills, and can be divided into wet mills and dry mills according to their processing conditions. cement mill structure ball mill is mainly composed of feeding part, supporting frame, rotary part, discharge, transmission, lubricant and cooling part.
Conakry ball mill vs rod mill how to choose ball mill or rod. conakry in the ball mill there are lattice ball mill and overflow ball mill in common use named by different ore discharge structure while there are only overflow type and open type rod mill generally with the same specification the diameter of the hollow shaft at the ore discharge end is larger than that of the ball mill 3.
For overflow ball mills, the charge should not exceed 45 of the mill volumeor grate discharge mills, the charge should occupy about 50 of the mill volumeond developedelationship that can be used to determine the percent charge by volume asunction of the vertical height above the charge, he, and the radius of the mill, r, i.e.,.
Generally,aximum allowed ball size is situated in the range from8 to4. the degree of filling the mill with balls also influences productivity of the mill and milling efficiency. with excessive filling, the rising balls collide with falling ones. generally, filling the mill by balls must not exceed 3035 of its volume.
