ball and material ratio of ball mill ratio

The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size 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% ...

The selection of the right grinding jar and the correct filling level has a big impact on the grinding result. Depending on the application you have to select the correct material and amount/volume for the grinding jar and the grinding balls. A jar filling should consist of about 1/3 sample and 1/3 ball charge.

The grinding jars oscillate back and for at up to 1800 rpm(30 Hz), translating through a distance of approximately 25 mm. This causes the grinding balls to accelerate through the space inside the jar, resulting in high energy collisions between both each other and the inside walls of the jar.
