Buell Gravitational Inertial Classifiers

The Buell Aggregate Classifiers combine gravitational, inertial, centrifugal and aerodynamic forces to efficiently classify materials at cutpoints ranging from 50 to 200 mesh (300 to 75 microns). 

Buell is promoting a special limited time offer on new purchases; a 3 year Free replacement of component parts on Manufactured Sand Classifier systems. Additional information regarding this offer can be obtained immediately by clicking on the “Direct Contact” button above and calling or emailing Colin Nunemacher or Clarence Kreiser.

The feed material and primary air enter the top of the unit and travel downward. The air makes a 120 degree change in direction. It then exits through the vanes, carrying fine particles with it.

The coarse particles that are too heavy to make the turn fall to the bottom where they pass through the secondary air before they are discharged through a valve. Secondary air, entering below the vanes, passes through the curtain of falling particles. Those particles that are near cutpoint in size are diverted by the secondary air stream into an eddy current within the heart-shaped chamber.

Some fines are captured as they enter the unit while others are drawn from the eddy. These are carried by the exiting air to a fabric filter for final recovery. The design of the Buell gravitational inertial classifier uses air flow, gravity and directional changes to achieve material cutpoints from 50 to 200 mesh.

The Benefits of Air Washing

  • No moving parts within material flow stream
  • Internal Lining - AR Plate or Ceramic
  • Reduce loading or eliminate settling ponds
  • Lower maintenance and operation costs (pumps, dredging, belt presses, flocculants)
  • Reduce moisture and minimize asphalt costs
  • Develop additional market opportunities for minus 200 mesh material
  • Environmentally friendly
  • Complement wash plants with upstream removal of fines to reduce water use and washed products, (where required)
  • No water necessary except for dust suppression
