ABSTRACT:
A two-mass heavy duty vibratory machine has a frame in the form of a box-like cage in which a working member, such as a screen, is received. In one embodiment of the disclosure, the frame is resiliently mounted on a stationary support surface and the working member is resiliently suspended from the frame. In another embodiment of the disclosure, the working member is resiliently mounted on the stationary support surface and the frame is suspended from the working member. In both embodiments, an exciter is mounted on the frame at a location outside the frame and spaced from the working member.
