Ball mills are different. The grinding media is unfixed steel ball, etc., which produces larger sized powder than grinding mill. the size of the discharged product can mainly be adjusted between 40250 mesh. If the size of discharged product is uneven, it is needed to equip a powder separating machine.

IIRC). Once the dial holders were replaced, the X and Y Ball screws were still the correct length. I noticed that the X ball screw came with a 2" extension section that was screwed onto the end of the shaft. That was left in place and I installed an X axis servo drive over the shaft with no spacing problems.

When Kincaid lignite was pulverized utilizing inthemill drying at product moisture content in the range of 11 to 12 percent, the comparison factor was for pulverization in the ball mill and in the hammermill. Power requirements at these conditions were kwhr/ton in the ball mill and about 17 kwhr/ton in the hammermill.
The ball mill is a very noisy machine, particularly if the cylinder is made of metal. Applications: Large ball mills are used to grinding ores prior to manufacture of pharmaceutical chemicals. Smaller ball mills are used for grinding of drugs or excipients or for grinding suspensions. Variants of Ball mill. Hardinge mill = Conical end cylinder
In the pharmaceutical industry, sometimes the cylinder is lined with rubber or porcelain. Figure 1: Ball Mill. The cylinder contains balls that occupy 30 to 50 % of the mill volume. The weight of the balls is kept constant. The ball size depends on the size of the feed and the diameter of the mill Balls are made of steel, iron, or stoneware.
