Centrifugal Slurry Pump Concentration Limit Testing and Evaluation – Expansion of FIPR 04-069-215







In the original study, tests were carried out on three different types of phosphate matrix slurries with regards to their pipeline friction, effect on pump head quantity and cavitation performance at (high) concentrations of solids around 40, 50, and 60% by weight.

Rheological tests were also carried out as part of FIPR contract No. 04-04-070 (Publication No. 04-069-215) on the fine carrier liquid component of the slurries by the University of Florida.

In this extension additional (necessary) matrix, transfer matrix, clay, sand-clay mix, and tails-type slurry models are provided as requested. These are all in the form of one Microsoft Excel spreadsheet for models with graphical output for use by mine planners to cover all phosphate mine pumping needs.
