Abstract

A sifting machine comprises a stationary sifting basket, a rotor rotating within the sifting basket and a worm conveyor feeding into an end of the sifting basket for dosing and introducing the material to be sifted. The rotor and the worm conveyor are driven for rotation, wherein, in order to achieve an optimal rate of revolution adjusted to the desired mode of operation for both the worm conveyor and the rotor, each has its own drive device. In order to facilitate removal, the unit comprising the rotor, the sifting basket and the associated drive mechanism can be axially removed from the sifting machine housing and subsequently pivoted-out in a sideward direction via a pivot bearing.
