ABSTRACT A sieve machine, consists of a sieve box and a sieve mesh that is directly movable by means of bumpers distributed over its surface, and mounted on striker bars that are arranged beneath the sieve mesh. The striker bars project from rods oriented transversely to the direction of movement of the material to be sieved and installed so as to be fixed in a frame. The striker arms have pivot levers that are caused to oscillate through the medium of a common push rod driven by a vibrator. In order to provide for an even better match between the sieve machine and the sieve behaviour of the material to be sieved, which also provides for simpler production, a) the rods are mounted at their ends by means of elongated metal- lic plate springs (101) that are oriented along the length of the sieve mesh (2) and are arranged at least approximately at the same level as the mesh, the plate springs being secured at one end on the sieve box and on the other to a rod (4); and b) an electromagnetic vibrator (10) acting exclusively linearly and permitting adjustment by frequency and/or amplitude is used as a vibrator.
