Industrial Plant Flotation Machines in Banks

Air flow is actually a direct consequence of liquid flow for a self-aerating cell such as the Wemco. For all other mechanical cells air and liquid flows are independently variable, air through adjustment of supply, and liquid by impeller speed variation. Table contains a number of derived properties of Denver and Wemco cells covering the full ranges of cell volumes. Although availability of ...

Numerical Simulations of Two-Phase Flow in a Self

Time-dependent simulations of two-phase flow in flotation machines are essential to understanding flow behavior and physics in self-aerated machines such as the Wemco machines. In this paper, simulations have been conducted for three different uniform bubble sizes (db = 0.5, 0.7 and 1.0 mm) to study the effects of bubble size on air

Precise Air Flow Measurement Improves Flotation Cell ...

The measured air flow is closely related to the air or bubble volume within the flotation tank. Therefore, measuring mass air flow rather than volumetric air flow increases the frothing process performance efficiency. Flotation cells are “aerated” with compressors or blowers and often with very little pipe straight run, which can affect the accuracy and consistency of flow meter readings ...
