Stators or Diffusers

A stator or diffuser is an important component of a mechanical flotation cell, which surrounds the impeller and acts as an internal baffle useful in reducing pulp vortex in the cell. The tangential flow of the agitated slurry (due to rotation of the impeller) is transformed to a radial direction for effective dispersion of gas and solids in the cell tank. This reduction in the vortex flow helps in maintaining a stable pulp-froth interface, essential for flotation.

A stator consists of a number of blades arranged in a concentric circle with gaps between the blades to facilitate movement of slurry in the cell tank. A stator is usually mounted on the bottom of the cell tank surrounding the impeller concentrically from its bottom. In some cell designs the stator is fitted to the standpipe such that the stator shrouds the impeller from the top and hangs with an open space at the bottom: this is commonly known as an overhung stator.

The impellers and diffusers are moulded and coated with rubber or polyurethane for abrasion resistance.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
