  • 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.
