From CSIRO’s Process Magazine, February 2008:
Although a rake may appear to be a fairly straightforward piece of technology, when used in mineral processing facilities, the difference between a well-designed or poorly-designed rake can mean millions of dollars in scaled, damaged or poorly operating equipment.
Research is suggesting that even small changes to the size, shape, location and angle of the rake blades, and speed of the rake movement, could make a big difference.
Working through the Parker Centre for Integrated Hydrometallurgy Solutions, CSIRO researchers are exploring how variations in the size, shape and spacing of rake blades and changes in operating conditions can affect thickener performance. Read more (pdf file, page 10).
