Fine Material Washer

Fine Material Washer | Superior Industries

Classify, Scrub and Dewater

Fine material is usually defined as 3/8” (9.5mm) and less. However, Superior’s fine material screw washers will accept a maximum feed of 3/4” (19mm).

In addition to minor scrubbing, the machinery is capable of removing clays, silt, and unwanted lightweight contaminants. Heavier material settles to the bottom and is augured up the tub.

As it proceeds up the incline, water drains from the material and is eventually discharged with a moisture content of 15-25%.

If you don’t have time or space to stockpile and dry this material, many producers pair with a dewatering screen to remove half of that moisture. Better yet, the Aggredry® Dewatering Washer is all processes in a single machine.

  • Single or twin screws
  • Capacities up to 1,100 STPH (1,000 MTPH)
  • Only fine screw capable of handling up to 3/4” (19mm) material

They’re the same neighbors you’d trust to babysit your dog on the weekend. Our factory-trained dealers are a local connection for sales, service and parts.

phone support

Staffed by agents born to serve others, you’re welcome to call our technical service team 24/7/365. (If you call in the middle of the night, we can’t guarantee they’re in uniform!)

replacement parts

You know the old saying…”square pegs don’t fit in round holes?” It’s often the case with knock-off parts. Genuine Superior parts are forged from the same steel as our equipment
