EIW - Blade Mills for Rock and Sand Processing

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 are very similar in appearance to Coarse Material Washers but function much differently. The major difference is that any material and water that enters the Blade Mill must exit through the discharge opening located at the bottom of the washer tub opposite the feed end, as these units are installed at a shallow slope position of 0° to 5°. There is no overflow in this type of unit. Using a combination of paddles and flights arranged in alternating format the entire length of the shafts, they begin to scour, abrade and break down deleterious material. The shafts can have different configurations but mainly the idea is to have alternating flights and paddles. Rock, sand, or a combination of rock and sand depending on the process plant location typically discharges directly onto a washing/sizing vibrating screen or dewatering equipment.
