10 10 Classification (Top) Hydroseparators (Middle) WEMCO screw classifier (Bottom) Hydrosizer

11 11 Hydroseparators A heavy duty machine which separates solids into fine and coarse fractions in the range of 5 to 200 μm. Used in a wide range of applications where a large pool area is required and the oversize or coarse fraction does not have to be thoroughly dewatered or washed in one operation. Cyclones that are used in the chemical industry typically have a continuous underflow discharge but they can also have accumulator tanks on the underflow for applications where the feed solids concentration is very low. Krebs offers cyclones that can make separations from approximately 10 microns and larger. Bowl desiltors Consist of a comparatively shallow flat bottomed tank or bowl, equipped with rakes. It is used to recover relatively fine sand overflowing the washing unit in several industries. Bowl diameters are up to 15 m and separations range from 45 to 150 μm. Machines are mainly used in steel plant scrubber cleaning systems to remove grit and in some applications to scalp off oversize solids before thickening. (Top) Rake classifiers (Bottom) Curved screens Hydrosizers Hydraulic up flow classifiers for producing a range of high quality solids fractions. Classifiers with up to nine connected classifying chambers. Slurry flows through the sizer longitudinally, from pocket to pocket with coarse to fine solids separation occurring in the direction of flow. Rake classifiers Rectangular classifier tank with inclined channel, equipped with reciprocating raking mechanism which transports the settled solids towards the upper discharge end. Solids are dewatered and, if necessary, washed by addition of wash liquid. Screw classifiers WEMCO Classifier is designed to settle and dewater relatively coarse particles from high volume, low percent solid streams. The special design of this unit also permits it to hydraulically transfer surges in flow of up to m³/h of wastewater without overflowing. Curved screens Feature uniformly slotted concave wedge wire screen surfaces for separation or classifying of solids in suspension. Continuous tangential feed either by gravity via an overflow weir, or pressure fed - depending on application and separation cut. Ideal for high capacity, fine separation of fibrous, non-abrasive solids in food and pulp and paper processing. Krebs cyclones The Krebs Cyclone is a low cost, free vortex centrifugal device used for separating solids from solid/liquid suspensions. Krebs Cyclones are used to concentrate feed slurries to centrifuges and filters in order to increase their capacity or to permit the use of smaller machines of lower horsepower. In many chemical process applications, cyclones may be used in place of centrifuges, filters, gravity settlers, or other more expensive solid/liquid separation devices.
