Sepor’s Cyclone Test Rig is designed for laboratory testing of classifying various solids in a slurry. It is equipped with a 2 inch Krebs Urethane Cyclone, a new, larger 283 liter sump (75 gallons), a 1-1/2 x 2 slurry pump with a 7.5 HP/220, 380 or 440 V/3 Ph/50-60 Hz TEFC motor, a frequency inverter for variable speed of the pump, pinch valve to regulate flow, internal piping and valves to circulate the slurry through the cyclone from the sump or to re-circulate the slurry, and a pressure gauge to monitor the pressure drop across the cyclone. All equipment is conveniently mounted on a sturdy structural steel frame with swivel castors for mobility.

The Gmax 2 inch cyclone has a typical separation range for particles of 15 microns in size. Typical applications for these cyclones are to dewater sol- ids in slurries, concentrate solids – especially when no solids exist in the slurry smaller than 15 microns, or to classify solids in slurries in the particle size range of 15 to 35 microns, with the large particle size going to the high % solids underflow and the fine particle sizes and most liquid going to the overflow. See cyclone performance table on following page.

The cyclone test rig uses Krebs. The Kreb cyclone’s results may be scaled up for process use, as they are manufactured for mineral and other industry applications. The cyclone test rig will operate cyclones ranging from 1/2 inch up to 4 inches. The volume of slurry required to produce desired separation ranges from 1.5 GPM @ 100 Feet of Head (1/2″) to 80 GPM @ 80 Feet of Head (4″). The pump and sump capacity would be too small for cyclones larger than 4″. Roughly, the particle separation size range for these sizes of cyclones is 0.5 through 82 microns. Custom cyclone test units may be designed for larger cyclones.
