Calculate volume capacity from length width and height User Guide. This tool will calculate the volume of a cylindrical shaped object from the dimensions of length and diameter. No conversion needed since length diameter and volume units can be selected independently so this calculator allows you to use any mixture of measurement units.

20191225The difference between ball mill and rod mill . 1. Shape and structure. The ratio of tube length to diameter of the rod mill is generally 1.52.0 and the inner surface of the lining plate on the end cover is vertical plane. The ratio of cylinder length to diameter of ball mill is small and in most cases the ratio is only slightly greater than 1.

Should be noted the productivity of ball mills depend on the drum diameter and ratio between the diameter and length of the drum. At the short ball mill grinding is a more rough and for grinding fineness a lot of material has to be returned from classifier to the mill it leads to mill overload.

20121126Rod 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.
