Abstract (en)
A sieve for powder materials comprises a screen (2) which is commandably rotatable about a horizontal rotation axis (x-x). The sieve is provided with a hammer device (4) for inducing vibrations on the screen (2). During the screen rotation, a striker mass (7) moves alternatingly between two extreme endrun positions, striking alternatingly against two endrun stops (8,9) which are solid with the screen and which are located at the extreme endrun positions. At each revolution of the screen, the striker mass completes a full back-and-forth run. When the striker mass strikes the endrun stops (8,9) the screen (2) is shocked by vibrations which cause the powder materials to dislodge from perforations in the screen (2) and therefore clogging of the perforations is prevented. <IMAGE>
