Blade Mills

Blade Mills can be used in a variety of applications and are designed to help producers begin liberating light, loamy clay or dirt from either coarse rock and/or sand before further processing.

Blade Mills resemble Coarse Material Washers in appearance but are designed for a different operational purpose. Installed at a shallow slope of 0° to 5°, Blade Mills do not use an overflow weir. Instead, all material and water introduced into the unit must exit through the discharge opening located at the end opposite the feed. This low-angle installation allows Blade Mills to achieve higher throughputs than similarly sized Coarse Material Washers. Blade Mills are commonly used in sand, aggregate, and mineral processing applications where effective breakdown of deleterious material is required prior to downstream screening or dewatering.

How Blade Mills Work

Blade Mills use a series of shafts equipped with an alternating arrangement of paddles and flights running the full length of the unit. As material and water enter the feed end, this paddle-and-flight configuration aggressively scours, abrades, and conditions the material, breaking down clays and other deleterious contaminants. Because the unit operates without overflow, both solids and water are conveyed along the washer box and discharged at the opposite end. Depending on the plant layout and material type, rock, sand, or a combination, the discharge typically feeds directly onto a washing or sizing screen or into dewatering equipment for further processing.
