Working Principle. D12 Lab Flotation Machine is mainly consist of the following parts lifting mechanism, machine body, stator and impeller part, inverter and control system All the parts are connected to the vertical column.The main shaft is driven by the motor to rotate in clockwise direction. The rotation speed of the impeller is controlled by the inverter.Flotation impellers would be expected to follow a similar equation, although a slightly different constant may be found. The circulation rates are very high. For example, a 14.2 m 3 cell with an impeller of diameter 0.84 m, rotating at 114 rpm, would have an internal circulation of 51 m 3 per minute, thus circulating the cell contents between.
