Classifying Tank

Classifying Tank AR136 12x48 Twin by Superior Industries

Blend Your Material to Spec

Common in dredging or applications that require removal of lots of water, classifying tanks are capable of accepting a variable out-of-spec feed and will produce a steady in-spec output. That makes them unique as most aggregate processing machinery prefers a steady input for equally steady output.

Material enters the tank via a sloped feedbox and then is classified by specific gravity. That’s a scientific term toward a fairly simple process: large or coarse particles settle first, mediums towards the middle of the tank and fines at the end. Any silts naturally flow over the sides of the tank.

Using a system of high-pressure valves that are usually computer-controlled, the material is blended back together according to your desired spec. Classifying tanks can produce as many as two spec products and one excess product.

  • Capacities up to 950 STPH (860 MTPH)
  • Produce three uniform products from single feed
  • Stationary, skid-mounted or portable models
