McLanahan - Blade Mills Brochure

Blade Mills, also known as Aggregate Conditioners, scour, abrade and break down water-soluble silts and deleterious clays from contaminated ores, coarse rock or sand feeds. They are most often placed ahead of wash screens to improve screening efficiencies or in front of other wash equipment to improve the Sand Equivalency (SE). Despite being very similar in appearance to Coarse Material Screw Washers, Blade Mills process material differently. For instance, all material that enters the box, must exit through the discharge opening as there is no overflow weir. Without an overflow weir, material must be discharged into another piece of process equipment and cannot be put on a conveyor belt.
