VetterTec screw presses are applied to dewater media containing solids. The product is fed to the pressing section through a feed hopper. In this section, the pressing screw compresses, tumbles and works the product so that water escapes through the screen cages. At the end of the pressing section, the material falls through the discharge hopper thus leaving the press.
VetterTec screw presses are used in a wide range of applications. Predominantly, they are used for mechanical dewatering, but also to wash out soluble parts of a product. For optimal operation, each press is especially tailored to its application. To this end, either a conical or a cylindrical design can be chosen, the screw geometry is adapted, the screen perforation optimized, the drive designed etc. According to requirements, pressing tests either on the customer’s site or in a lab can be a useful supplement.
