Wet screens | RHEWUM DFN
For many processing tasks the use of wet screens is required. The product in suspension is fed by suitable feeding systems (syphon, overflow pipe or similar) onto the screen width. The liquid used depends on the product and when passing the mesh takes along a certain amount of fines to the outlet.
Desagglomeration with RHEWUM wet screens
This process is supported by the double-frequent direct excitation of screen net which simultaneously ensures smooth transport of the coarse material. The flow forces aroused by the liquid additionally deagglomerates the material. In many cases this can be boosted by an additional watering device. Since the RHEWUM DFN wet screens does not use air jets the used liquid can be recycled after sedimentation of the solids.
The double frequency wet screens DFN with three additional wettings have proven successfully for production of clean product.
In addition, a static machine casing encloses the vibrating screening unit and thus enables fixed flange connections as well as a dust-tight screening process (FDA, ATEX).
Furthermore task case and spray systems are optionally available.
