Research Centre utilises a WEMCO® attrition testing machine An octagonal stainless steel attrition cell mimics full scale equipment and expected hydrodynamic patterns The testing scale agitator also mimics the full scale WEMCO Attrition Scrubber design comprising three stacks of opposing pitched blades
Each of the flotation machines contained a certain amount of stagnant volume and this varied from 7% of the WEMCO machine s effective volume to 45% of the Outokumpu volume Although the concept of perfect mixing is seducing the best method to interpret the residence time distribution data is to use a multiple parameter model
Coupled with knowledge of the expected residence time this provides new insight into the flow characteristics of the individual machines that were evaluated Each of the flotation machines contained a certain amount of stagnant volume and this varied from 7% of the WEMCO machine s effective volume to 45% of the Outokumpu volume
