Attrition Scrubbers, also known as Attrition Cells, are used to liberate deleterious material and remove it from competent aggregate material. They are also proven to liberate clays, reducing product turbidity, and to break apart loosely conglomerated clusters in Frac Sand Plants.
In an integrated process utilizing both conventional Separators™ and attrition technologies, Attrition Scrubbers can be used in glass sand, frac sand, clay, and sand and gravel production, as well as in the preparation of flotation feeds and reagent washing.
Cells are typically fed material by Hydrocyclones, Separators™ or Hydrosizers™ to present the material at a high density to achieve the best scrubbing action possible. The connection between these two pieces of equipment is designed to minimize the risk of foreign objects entering the cell.
Attrition Scrubbers produce a high shear environment in which particles scrub against themselves to scour their surface and liberate deleterious materials. All internal parts are completely rubber-lined to maximize wear life and minimize time and costs of replacement parts. Attrition Scrubbers are also engineered with direct drives to eliminate maintenance upkeep of conventional V-belt drives.
To ensure safety, dilution water is added at high power draw. In the event of high draw, the motor shuts off to prevent damage to it, as well as to the gearbox and the shaft/paddles.
McLanahan Corporation is able to perform laboratory testing of samples to determine the number of cells required in the field.
In Wisconsin, press reports have called frac sand the “new gold rush,” because of its critical importance in the process using hydraulic fracturing – or fracking – to extract oil and natural gas. The state’s abundant deposits of coarse-grained quartz sand have been mined for more than 100 years, but today, oil and gas industries prize this sand that is found in the state’s countryside.
