ABSTRACT:
A conveying device (1) for granular material (2) to be transported has a conveying line (3) which is connected to a suction appliance (7). Along the conveying line (3) is an induction coil (8), which is connected to a control device (10) for a discharge flap (13). By means of the latter, metal particles (2') are separated from the material (2) via a discharge opening (23). The discharge flap (13) and the discharge opening (23) lie inside a separator container (9') of a metal separator (9) through which runs the conveying line (3). The conveying line (3) also has inside the separator container (9') an inflow opening (31) through which the air passing into the container (9') during separation of the metal particles (2') can flow back into the conveying line (3). Since the separator container (9') is directly connected to the conveying line (3), a bypass line can be dispensed with so that a simple and inexpensive line guidance is achieved. Futhermore, the discharge flap (13) does not need to be sealed, and a high conveying capacity and consequently a high efficiency of the device (1) is ensured.
