The Sweco Hydrocyclone Systems provide an economical and effective method for removing solid particles in the 4 to 100+ µm range from slurries. Hydrocyclones typically make finer separations than are practical with screening separators and at significantly higher capacities, says the company. In many applications, cyclones can be used in place of decanting centrifuges, providing the desired results at lower cost, adds the company. Hydrocyclones are supplied in either an open-manifold or a packed-vessel configuration. Manifolds (radial or linear orientation) utilize 2-, 4-, 5- or 10-in. dia. cyclones while packed-vessels contain either 1- or 2-in. dia. cyclones. Both configurations can process feedrates from 10 to 3,000 gal/min, depending on the size and number of cyclones in the system. — Sweco, a business unit of M-I LLC, Florence, Ky.
