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.
- The use of a Blade Mill, if suited for the duty of service, will be the lowest cost machine and lowest kW (HP) power choice for ore and rock washing over most other options
- McLanahan Twin-Seal Pak submerged rear bearing assembly incorporates Caterpillar Duo-Cone® seals that keep water and even the smallest particles from reaching the bearing. This is a far greater rear bearing assembly design over any competitor’s offer.
- Shafts flanged at each end to facilitate maintenance are straightened to ensure maximum wear life
- High brinnell, abrasion-resistant white iron wear shoes and paddles provide long wear life
- Shafts utilize staggered wear shoe and paddle configuration to abrade and convey material
- Wear collar at feed end protects mating shaft flanges and hardware from premature wear
