ABSTRACT:
A method and apparatus for classifying particles which essentially comprise a circular chamber with first and second ends. A high pressure inlet is mounted tangentially to the side of the circular chamber and a high pressure outlet is, likewise, mounted tangentially to the chamber. A low pressure inlet and outlet are mounted to the end of the chamber. The second end is adjustable toward or away from the first end. When a high pressure fluid is communicated to the high pressure inlet and high pressure fluid is removed from the high pressure outlet, a certain portion of the high pressure will be moving toward the low pressure outlet. The particles to be separated are injected axially into the chamber. If the particles are of sufficient weight, they will move by centrifugal force to the high pressure outlet. The remaining particles will move because of the drag created by the fluid moving from the high pressure inlet to the low pressure outlet to separate the heavy particles from the light particles. Movement of the end plate will change the drag force thus changing the particle size separation.
