Regarding elliptical vibrators WIMA separates the wheat from the chaff. Elliptical vibration screen machines are constructed with a combination of circular and linear vibrator. We generate an elliptical vibration by superposition of both basic forms – preferably electronically for fine and individual adjustment.
The unbalance exciters consist of unbalance disks which are attached on each side to a solid shaft. The out-of-balance is therefore only generated by the disks. By the outside located gravity of the unbalance disks the total weight of the exciter is strongly reduced. The reduction in weight affects a lower load of the bearing and thus results in a bearing life extension.
