The mean gas holdup was 8.8%, and consequently the effective pulp volume of collection zone was 91.2%. The gas concentration on top of froth was recorded for RTD measurement of the gas leaving the cell. It was found that the mean gas residence time was around 42 s and the mixing condition for gas and pulp was similar.

Ask the Physicist!

Since "w" is constant (the ball stays in the Vslot), and "r" is increasing (the ball is moving away from the center), then "v" must also also be increasing (the rotational speed of the ball). Since "v" is a squared term in the formula f = v * v / r, then the centrifugal force "f" pulling the ball away from the center is INCREASING over time.

The impact velocity of the balls relative to the vial walls is determined from the indent size. A model correlating velocities with indent radius is described. Velocities were determined for the Spex mill ( 1.83.3 m s l) and for a new high capacity mill (2.63.8 m s l) and were found to be strongly dependent on ball size. 1.
