Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = 6.9Wt/Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/6.9Wt are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
Mix for 4 hours in the ballmill with brass media; 2. 75% potassium nitrate. 20% sulfur. Mix for 4 hours in the ballmill with brass media; 3. Mix the two compounds in the ballmill WITHOUT the brass media for an hour. Of course between the first and the second step the barrell and the medias must be carefully cleaned!

Ball mill balls. Ball mill balls are a type of ball used in ball mills, usually made of high-hardness materials such as steel, ceramics, hard alloys, etc. Ball mill steel balls is an important part of the ball mill, its main function is to carry out the grinding operation in the ball mill, and the material is crushed into the required size.
Ball mills can be used to further break down or refine a single material, or you can place multiple materials into a ball mill jar to mix as you pulverize -- this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes. Ball mills basically function like a mortar and pestle, but on a much larger scale.
