However, not many high Cr balls are used in primary grinding because the improvement obtained in wear resistance relative to steel, typically 25 – 30%, is not enough to offset Its higher cost. In primary ball milling, wear speed is largely independent of ball diameter and mill volume.

Finally, a cylindrical mill with a grid was used. The grid was 1 foot from the feed end of a 2- by 3-foot cylindrical mill. Balls of 2.5 inches to 1 inch were placed in the feed-end sections and 0.75-inch balls in the discharge end. The grinding was moderately better than without the grid.
Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.

Ball mills are a fundamental part of the manufacturing industry in the USA as well as around the world. Ball mills crush material into various sizes and extract resources from mined materials. Pebble mills are a type of ball mill and are also used to reduce the size of hard materials, down to 1 micron or less.

18.104.22.168 Ball mills. 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.

Skills For Adding Steel Balls In Ball Mill. After the ball mill is installed, after normal continuous operation for two or three days, check the meshing of the large and small gears. When everything is normal, add the remaining 20% steel balls. The proportion of steel balls in the ball mill is a more complicated technical issue.
