Key benefits of WEMCO attrition scrubbers

Our attrition scrubbers

WEMCO attrition cells are suitable for several applications, such as pre-treating pulps for higher flotation recovery rates and product quality, and to produce glass and industrial sands. They are also used to liberate compacted minerals and for desliming to reduce contact time by maximizing surface exposure to the solvent.

Maintenance & Services of our WEMCO Attrition Scrubbers

The experts at the FLS Minerals Testing and Research Centre help fine tune your attrition process to ensure optimal performance. Equipped with a range of testing and analysis equipment, we determine the optimal sizing, configuration, and operating practices for your application.

Operating attrition cells are supported by a global network of service centres, offering full-lifecycle technical assistance. Our service engineers travel regularly to sites for equipment inspections and audits, to supervise maintenance, and to deliver tailored training. Meanwhile, FLS spare and wear parts deliver long service life and ensure the performance of your attrition scrubbers does not degrade over time.

Frequently asked questions

FAQs on scrubbing and attrition scrubbers

Attrition scrubbing removes surface contamination, impurities, and pollutants from feed materials, balancing power and control to clean particles without degrading the product.

Attrition scrubbers benefit mining operations by cost-effectively enhancing and improving product quality. 

WEMCO attrition scrubbers work with percent solids of 65% up to 75% or even 80%, depending on the application. 

The ability to effectively scrub particles to the desired conditions depends largely on how they remain in the attrition scrubbers. This retention time is a function of the cell’s active volume and feed rate. We offer a range of models with active volumes from 1.7m3 (60ft3) to 5.7m 3 (200ft3), allowing us to design circuits with the right size and quantity of attrition cells to deliver the required retention time to achieve the required cleaning. Installed power is critical when planning the electrical layout and determining the return on investment. Finally, whether it’s a new construction or retrofit, the overall size and footprint of an attrition cell are important factors in circuit design and cost.
