According to Jobin et al., after attrition scrubbing, the increase in fine size particles could be due to their positive correlation with the diameter of the sand introduced in the scrubber: the authors observed an increase up to 7% of fine particles for the 0.250–1 mm sand fraction and up to 10% for the 1–2 mm fraction.
The study was carried out to produce high-purity silica sand used for glass making. Generally, all grades of silica sands are comparable in their chemical composition except for iron oxide (Fe 2 O 3) content, which is slightly rigid and its concentration varies for different applications.The objective of this work was to increase silicon dioxide (SiO …

If you are headed towards frac sand production, you can acquire large industrial scale attrition scrubbers. The key to attrition scrubbing is creating a "pulp on pulp action" where the flows of sand and water (or in some cases acid-water) flow against each other, and the sand is in a way sandblasting itself and removing the clusters.

Physical separation methods are normally preferred over chemical methods, but their efficiency often fails to meet the remediation targets for various reasons. Attrition scrubbing could possibly be used to improve their effectiveness. The aim of this study was to demonstrate the usefulness of attrition scrubbing prior to a gravity separation …
Attritioning has been a method of improving mineral extraction for over 60 years, however it is only recently that an understanding of the mechanism employed and the improvement in efficiency that have been achieved.The paper will discuss these improvements and how to overcome the problems that have been raised. At present there is a dearth of …
The most important function of the attrition machine is the scrubbing of particle scrubbing of particle surfaces to remove film or coating. Application. GTEK's versatile attrition scrubber is specially developed for a vast range of applications: Cleaning of silica sand for glass making; Liberation of mineral from slime coatings;
In some deposits valuable heavy mineral quality is poor due to increased mineral surface coatings from higher slimes and more competent sand orebodies. Mineral surface coating can include silica or aluminium rich clay minerals and iron based minerals that render the final product quality off-specification, in this case specifically ilmenite and …

McLanahan Attrition Cells are optimal for industrial (frac, glass, sports) and mineral sands to meet turbidity and color test requirements. They are designed to scrub the surfaces of particulates, liberate deleterious …
Attrition scrubbing provides for excellent mixing and surface abrasion and has been used successfully, one example being to speed up the leaching dynamics of gold ores [15]. The attrition scrubber has also been employed as a suitable remediation process for contaminated soils; in this case, the process removes particles and contaminants …
In general, solids that have a low porosity such as sands will be better suited to attrition scrubbing than solids with a high porosity such as limestone's and sandstones. The structural strength of the solid phase is important as if the solid phase has a low structural strength then the solid particles may be broken up in the attrition process ...
[0003] Attrition scrubbing, specifically hydraulic shear attrition scrubbing, is a process by which particles are scrubbed by thrusting the individual particles into one another at high speeds. The friction created by the high speed collisions functions to effectively shear the undesired material, for example surface contamination, from the ...
