Abstract (en)

[origin: EP1210987A2] Device for separating a sand mixture into a fine and a coarse fraction comprises a sieving drum (1) having a drive shaft (10). The sieve wall (5) is rotatably connected in its upper region so that the drive shaft protrudes against the drum in the conveying direction of the sand mixture. The shaft is a component of a connected screw conveyor (18) having a stationary housing (19) and a conveying screw (20) arranged on the shaft. The lower front wall (4) of the drum rotates on the housing of the screw conveyor. A threaded deflecting plate (9) is provided on the inner side (8) of the sieve wall. Preferred Features: The sieving drum has a larger diameter than the screw conveyor and is surrounded by a housing having a removal support for the fine fraction in the lower region and a removal support for the coarse fraction in the upper region.
