1 and 2 overflow and a mass balance split for the two cyclones is used to predict the total particle size to flotation. To calculate the mass split from the two cyclones, an energy balance for the two pump circuits is used. From the energy balance, the measurements that are available are retained, and from that Equations 2 to 5 are developed.

Unbalance - The Common Cause of Vibration Premature Bearing Destruction within Rotating Machinery Equipment. Unbalance is defined as an unequal distribution of mass causing the mass axis to differ from the bearing axis. During rotation, the unequal mass along with the radial acceleration due to rotation create a centrifugal force.
