A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell. Ball mills are commonly used in single stage fine grinding, regrinding, and as the second stage in twostage grinding circuits.

The formula for critical RPM is /sqrt (mill ID media diameter). Both the ID and diameter are in inches. This is the RPM that media will stick to the walls of the jar. Typically, we shoot for about 65% of that value. For that particular jar with 1/2" media, you'd want to shoot for about 67rpm.
Features: All sizes have quickchange snapin liners This feature is especially significant when varied materials are milled and cross contamination must be avoided Using a separate liner for each material protects the product, saves cleanup time, reduces number of jars required.
The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (nonspherical, irregularly shaped and mixedsize media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58% ...

In a planetary ball mill, each jar represents a "planet". This planet is located on a circular platform, the socalled sun wheel. When the sun wheel turns, the jar rotates around its own axis, but in the opposite direction. Thus, centrifugal and Coriolis forces are activated, leading to a rapid acceleration of the grinding balls.

I ran 2 tests for 30 seconds, one test with my old PVC jar and one with the new stainless jar. The average reading over the 30s was dB on the stainless jar and dB on the PVC jar, to me they essentially sounded the same loudness but the steel one did have a slightly different metallic sound (obviously lol).
1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
