Surface chemistry, clean lines of attrition material and the treatment of fines significant advances in the understanding of attritioning highlighted. CITATION: Baguley, W, 2013. Attrition scrubbers, in Proceedings MetPlant 2013, pp 229-246 The Australasian Institute of Mining and Metallurgy: Melbourne .
The attrition scrubbers have two opposed axial flow propellers 100% and 150% pitch to create a high intensity impact zone between these propellers. Each particle is violently impacted with many other particle surfaces many times before discharge from the vessel. The actual scrubbing time is dependent upon residence time in the attrition scrubber.
The scrubbers are also available with a range of lining material to suit particular chemical requirements. These machines are suitable as reaction vessels in leaching plants, as the attrition effect can reduce the overall retention time required.
Description. Attrition Scrubbers Provide Intense Scrubbing Action at Densities of 70%-80% Solids. The Attrition Scrubber provides a simple, economical solution to many of today’s beneficiation problems. Many products can be made marketable by the removal of surface films, coatings or slimes.
Attrition Cell Scrubbers PHOENIX Attrition Scrubbers deagglomerate material and remove surface contaminants from sand and other granular materials. These Attrition Scrubbers feature a compact design, robust construction, high throughputs with efficient slurry mixing, and deliver factory assembled for ease of installation and relo ion.
The design and selection of drum scrubbers is an inexact science at best with little published data on selection criteria or calculation procedure. To date most scrubbers have been selected on simple criteria such as global slurry residence time rather than more rigorous criteria such as & 39;solids& 39; residence time or degree of attrition.

Single cell attrition scrubbers may be operated as batch units. Multiple cell attrition scrubber units are designed to create a continuous flow through the bank of cells. The discharge from the first cell is forced down and under the propellers of the second cell, where the flow is upward and is discharged to the top of the third cell.
