The RHEWUM screening machine type WAF is a combination of direct excitated WA screen and a linear motion vibrating conveyor.
Two counter rotating unbalance motors generate a linear motion, which ensures the transport of the material. In addition, the screen cloth is excited by magnetic actuators which mechanically stimulate the high-frequency oscillations. This combination as well ensures that also for sticky material the screen cloth is kept free reliably.
This additional and innovative drive excitation combination enables a separation of material, which usually cannot be classified on linear motion vibrating screens. In this process the material is classified precisely and with high-capacity. In the range of ﬁne and ﬁnes particles with the machine type WAF much better screening results are achieved than with conventional linear motion screens.
