Nov 27, 2017· The length-diameter ratio of rod and ball mill drum should be around 5. The ratio between the length of rod bin and the effective diameter of the mill should be between 1.2 and 1.5. The rod length is about 100 mm shorter than the rod bin, so that steel rods can be arranged in parallel to prevent cross and collision. (4) Gravel mill.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T

ball mill length and diameter ratio-mining equiments supplier. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
