Fundamentals of balancing. With rotating bodies, imbalance is an omnipresent phenomenon. A typical example are rotating tools on machine tools. Because unbalance creates a centrifugal force, it increases linearly with the unbalance and squares with the number of rounds. The faster the rotor rotates, the more noticeable the unbalance.
In engineering terms there must be mass balance, what goes into a machine or process must equal what comes out of a machine or process. The result of ring-around mass imbalance is fully appreciated and understood by most floor sweepers, utility persons and mill operators, and can be mathematically described by engineers using differential calculus.

(b) We take nozzle as the system, which is a control volume since mass crosses the boundary. The energy balance for this steady-flow system can be expressed in the rate form as && & && EE E EE in out in out −= = Rate of net energy transfer by heat, work, and mass system (steady) Rate of change in internal, kinetic, potential, etc. energies ...
Electronic scales are load cell type, electromagnetic type, and tuning fork type, and all measure a standard weight in order to accurately show mass values and require calibration. Recent models have a calibration weight built-in. Models for weighing from a minimum of 30 g to a maximum of 31 kg are available, and the minimum display is from 0 ...

The hydrocyclones are one of the most unstable parts of the grinding circuit, since it relies on the efficiency of a ball mill. Therefore, measuring density in the hydrocyclone feed would be mandatory to have a more stable operation, and other points, such as cyclone underflow and overflow are also recommended for mass balance calculation.
