Our non-vibrating systems for the processing of suspensions.
SIEBTECHNIK curved-screen systems (type ZB or ZBB) are dynamic dewatering and classifying screens, even though they contain no mechanically moved parts. The system consists of a stationary housing that is fitted with a concave-curved screen cloth. The systems have been specially developed for the separation of solid materials from process or waste water and achieve optimum results at a low cost.
Material is fed pressurelessly either by static height or by external sludge pump. The suspension is fed into the feed chamber so as to ensure even charging over the entire width of the curved screen. The screen cloth slot apertures running across the direction of transport separate the liquid from the solids. Solids that are smaller than half slot width pass with the water into the underflow, so classifying the materials. The dewatered solid is discharged at the end of the curved screen. Curved screen systems and screen cloths are mostly manufactured from 1.4301 material but can, if required, also be manufactured from 1.4571 material.
