Generally, filling the mill by balls must not exceed 3035 of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length. Optimum ratio between length L and diameter D, L D is, usually, accepted in the range 1.561.64.
The equation below shows the relationship between ball mill grinding efficiency and material fineness K d G 2 G 1 d 1 d 2 X 1 Note. K d the relative productivity of the mill G 1 amp G 2 respectively represent the mill output T h when the feed particle size is d 1 and d 2
efficiency, with a consequent increase in mill through-put. Reduction of the bypass is the main means of boost-ing the mill throughput when the modernization con- sists of replacing a classifier of an older generation. The high efficiency classifier allows an increased feed of fresh material to the ball mill by avoiding the return of fine
If your product size needed is 100 passing 45 micron, then the ball mill total discharge material will contain normally 30 of 45 micron. The rest is oversize which has to be ground again. When this load is passed to classifier you may get only 20-25 product, the bypass of 5-10 R45 comes back to mill

If using a nominal diameter value of the tool when calculating the cutting speed of a ball nose or round insert cutter, the true cutting speed, v c, will be much lower if the depth of cut, a p, is shallow. Table feed and productivity will be severely hampered. Base calculations for cutting speed based on true or effective diameter in cut, D cap.

Ball nosed cutters slow nose speed. The biggest challenge with ball nosed end mills of various kinds is slow nose speed. As you get closer to the tip, the diameter on the ball gets smaller and smaller, finally going to zero. As a result, the cutter must perform over a wide range of surface speeds and chip loads at different depths in the cut.
Ball mills are predominantly used machines for grinding in the cement industry. Although ball mills ... The productivity of the mill system as observed from the plant data is given below Parameters Month Average ... which is contributing in higher circulating load and high bypass High fines quantity in separator reject. ...
If only ball consumption is considered, the higher the hardness, the lower the consumption. But for the productivity of the ball mill, the productivity increases with the increase of the hardness of the ball in a certain range, but when the hardness exceeds a certain range, the productivity of the mill decreases.
The typical closed ball milling circuit is shown in Figure 1. The circulating load ratio is known to be an extremely important designoperating parameter, as shown in Figure 2. Figure 1. Standard Ball Mill Circuit Arrangement . Figure 2. Ball Mill Circuit Productivity vs.
