The SWECO sifter can cope with demanding screening applications such as activated carbon, fertilizer, frac sand, limestone, petroleum coke, plastic pellets, PVC powder, roofing granules, salt, sugar, and more. It has the potential for 240 ft2 (22 m2) of screen area in one machine with 12 ft (3.7 m) of screen deck length.
The BigMax allows one to four separations in a single machine, depending on the desired deck configuration. The machine can feed the material at a single point or independently to each deck. Quick screen changes are possible from either end of the machine without the need to remove the ball trays. The over- and under-size material from each deck can be sampled individually.
