Attrition Scrubber – Floatex Separations Ltd

Attrition Scrubbing is a process where a mineral is scrubbed by the action of one high speed slurry flow impacting on another. The advantage of this type of attrition is that as it is being provided by two slurry flows there is little wear on the machine itself. Two opposed, shaft mounted, turbine type impellers generate opposing slurry flows that provide high particle on particle impact. The ...
