Feb 14, 2018 To separate the mill dust from the ball mill media, put a round 20-mesh screen into the mouth of a bucket that is the right size to hold it. A screen-type colander that is about 20-mesh works, too. The screen should be firmly attached to the frame of the colander. Carefully open the ball mill jar and gently pour its contents into the screen.

The influence of mill speed and pulp density on the

The influence of mill speed and pulp density on the

The pulp weight in the mill is obtained by subtracting the mill weight during the test from the empty mill weight, including the ball charge, at the start of the test. The pulp volume of the pulp in the mill is then calculated using the mill discharge density (before dilution) obtained during the sampling.
