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 ...

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 2) content to at …

A standard Denver Attrition Scrubber employing double-opposed-pitch propellers was used. Attrition scrubbing cleaned by abrading the sand particles with each other, rubbing away surface layers of iron minerals and clay. The scrubbed sand was deslimed by decantation through a 200-mesh screen. Table 2--Results of attrition scrubbing tests.

Attrition scrubbing experiments were carried out using a WEMCO 1L lab-scale attrition scrubber with a constant impeller speed of 1000 rpm. Clean low iron silica sand in size range of 2360 µm – 850 µm was used. In this study, the pulp density of 70 wt% with 10 wt% ratio of spent LIBs to silica sand media is used. The attrition time then ...

When an aggressive scrubbing is needed to remove tough, heavy clays from sand-sized particles, an Attrition Cell is the machine for the job. They are specifically designed to remove tough, high plasticity clays from materials less than ½" (12mm). Keep in mind, though, that an Attrition Cell is not a sizing or classifying device.

The attrition scrubber is also called attrition cell, attrition tank, or attrition machine. It is used to scrub the pulp with a concentration of 65-70% and to scrub the mud and fine sand on the ore. Dispersing the slime in ores to remove the impurities on the ore surface can create conditions for subsequent mineral processing and is an important part of the mineral processing production line.
