The optimal classification with RHEWUM vibrating screens
High performance vibrating machine type WA are used for classification of bulk material in the finest to medium grain size range. This screen type is a vibrating screen which employs direct excitation of screen mesh; thus the screen housing only takes a static function. It also preserves the building and/or the steel structure. No dynamic loads are transmitted as they are created by completely vibrating conventional screens and rigid connection to on-and off-going chutework is possible.
Vibration is imparted into the screen cloth by high speed movement of a transversally mounted rocker shaft, located beneath the screen cloth. Therefore the velocity down the screen is determined by the angle of the screen deck. Outside the screen housing rugged electromagnetic drives rock the knocker shafts, conveying the high frequent oscillation directly into the screen mesh. The electromagnetic drives create high accelerations on the screening net which are up to 15 g and more. These high accelerations guarantee also a correct screening of adhesive products. The electronic control of the vibrating heads allows infinite control of the vibrator oscillation during operation and therefore a perfect adaption of vibration amplitude to product changement. Each screen deck is individually controlled and divided into inlet and outlet sections.
RHEWUM is an independent family owned company which was founded in 1927 as „Rheinische Werkzeug- und Maschinenfabrik“.
We have been developing and manufacturing screening machines and vibrating feeders since the beginning of the 1950s.
These cover the entire field of dry and wet screening machines for a vast variety of applications for leading companies worldwide.
Optical sorting is the logical extension of our activities for the future.
Our customer’s requirements serve us as a benchmark and challenge – a continuous and economic production of well defined screening machines in reproducible qualities.
Choosing our screening and classifying technology our customers are always one step ahead of their competitors as they are able to offer the finest quality products.
