Abstract
The invention relates to a stator for a flotation cell to be used in the flotation of slurry-like material, such as ore and concentrate containing valuable minerals, by means of which stator the orientation of the slurry flow created by the flotation cell rotor can be controlled. The stator is composed of at least three structural elements to be installed around the rotor provided with at least one flow regulator.
Claims7
A flotation cell for use in the flotation of slurry-like material, such as ore and concentrate containing valuable minerals, the flotation cell comprising:
- a rotor mounted to rotate about an axis, and
- a stator including at least three structural elements angularly spaced apart around the rotor,
- wherein each structural element has first and second opposite ends and comprises at least two flow regulators, a supporting structure that is attached to and interconnects the flow regulators at the first end of the structural element and by which the structural element is connected to the flotation cell or to a stator fastening structure in the flotation cell, and a connecting element interconnecting the flow regulators at the second end of the structural element,
- the flow regulators of each structural element are disposed substantially parallel to each other,
- and a structural element is manufactured by separately casting the flow regulators, the supporting structure and the connecting element, assembling the flow regulators, the supporting structure and the connecting element to form the structural element, and interconnecting the flow regulators, the supporting structure and the connecting element by welding.
