Flotation Machines

NewCell Technology

WHY IT WORKS – Direct feed to the rotor eliminates feed by-pass of the high shear zone, thereby reducing the size and number of cells required in a concentrator.

70% savings in Opex.
60% less retention time required.
60% savings in Capex.

Features

A direct feed into the high shear zone of the rotor/stator.

A rotor design that pumps feed into the cell via internal draft tube.

A cell design which eliminates the need for suspending solids.

We bring flotation machines to the industry that incorporate our latest developments in rotor design.

The benefits such as improved recoveries, reduction in power, and wear are now available to existing concentrators with our simple retrofit design.

During the past years we have investigated the design of current forced air floation machines and form this research combied with the application of fluid dynamics we have developed a superior flotation rotor.

Our F1 rotor offers improved pulp circulation, better solids suspension, and increased air dispersion. Our laboratory tests showed a much faster float when compared to an established rotor design and the plant trial has improved the recoveries by 3%.

Benefits

As there is no by-pass of the high shear zone the need for multiple cells is eliminated.

With current cells a lot of energy is required to keep the solids moving and limiting sanding – this is not the case for the NewCell.

The expensive civil infrastructure will no longer be required for the installation of these cells. The self-feed pumping feature will mean that if more than one cell is used, they can be on the same level.

A direct result of much less energy being required, is a reduction in turbulence in the cell and therefore higher recoveries will result.

Typically, 70% of the overall cost of running a conventional flotation plant is power consumption. The NewCell concept requires 30% of the motor power for each cell and requires half the number of cells.
