Achieve the strongest possible scrubbing without reduction of particle size
Controlled turbulence for effective attrition
Attrition scrubbers are used to scour particulate surfaces, removing undesired materials and breaking down clays – cleaning and desliming the particles prior to other treatment processes. It is the friction between the particles, created by turbulence and supplied by the machine’s impulsion, that provides the highly efficient cleaning action. The action does not reduce the sound particles in size, as there is no grinding of the material. The only degradation that takes place is that of soft particles, such as clays, or cemented materials.
We offer a variety of attrition cell machine arrangements, based on your specific application. Prior to making a recommendation, we test your material in our laboratory to determine your optimal attrition scrubber configuration. This ensures you receive the appropriate machine, in the correct size and with the proper quantity of cells, for your operation.
With more than 50 years of experience with attrition cells, we have units installed around the globe. Call on our experienced engineers and support staff to ensure your attrition stage delivers the most cost-efficient and effective particle scrubbing for your operation.
Applications for attrition scrubbers
Flotation – cleaning particle surfaces prior to flotation to increase selectivity.
Glass sand – removing iron oxide coating on silica sand by attrition and flotation to produce a low-iron glass sand.
Industrial sand – Scrubbing blasting sand and fracturing sand to disperse contaminating soft particles and other impurities, which are then removed by desliming. This process helps your sand product meet API standards by creating a high purity, more crush resistant silica sand that will meet your customers’ specifications.
Ores and other minerals (e.g. phosphate) – freeing impurities so they can be removed with the help of a spiral classifier or hydrocyclone.
Dissolving solids – using the attrition machine to dissolve solids, reducing contact time by continuously exposing fresh surfaces to the solvent.
