Abstract

The invention relates to a gravity separator having the following features:

a channel-like portion having a transport unit, along which a material to be classified can be transported from a feeding end to a classification chamber, a closure unit which is arranged on and/or in the channel-like portion, the closure unit can be moved perpendicularly relative to the transport direction of the material to be classified and is arranged in such a manner that it rests on the material which is transported through with at least a portion.

Claims

1. Gravity separator having the following features:

1.1 a channel-like portion (14) having a transport unit (18), along which a material (22, 24) to be classified can be conveyed from a feeding end (14z) to a classification chamber (10),

1.2 a closure unit (26) which is arranged on and/or in the channel-like portion (14),

1.3 the closure unit (26) can be moved perpendicularly relative to the transport direction (20) of the material (22, 24) to be classified and is arranged in such a manner that it rests on the material which is transported through with at least a portion.

2. Gravity separator according to claim 1, wherein the closure unit (26) rolls on the material which is transported through.

3. Gravity separator according to claim 1, the closure unit (26) of which comprises a roller-like member (28).

4. Gravity separator according to claim 1, the closure unit (26) of which is arranged at the feeding end (14z) of the channel-like portion (14) and the feeding end (14z) is configured so as to correspond to the shape of the closure unit (26).

5. Gravity separator according to claim 1, the closure unit (26) of which comprises a continuous conveyor belt (42).

6. Gravity separator according to claim 1, the conveyor belt (42) of which, together with the transport device (18), forms a guiding path for the material (22, 24) to be classified which tapers in the transport direction (20) of the material.

7. Gravity separator according to claim 1, the closure unit (26) of which is supported at least in portions in a floating manner.

8. Gravity separator according to claim 1, the closure unit (26) of which is supported so as to oscillate at least in portions.

9. Gravity separator according to claim 1, the closure unit (26) of which is constructed so as to have, on the surface thereof, freely protruding webs (30) which extend transversely relative to the transport direction and in the direction towards the material (22, 24) to be classified.

10. Gravity separator according to claim 1, the transport direction (20) of which comprises a transport belt.

11. Gravity separator according to claim 1, the closure unit (26) of which is driven in a motorised manner.

12. Gravity separator according to claim 1, the closure unit (26) of which is composed of steel.
