## Abstract

An apparatus comprises a vertically extending receiving hopper (1) having a guide funnel (2) in the bottom part thereof. A disk (3) having at least one discharge opening (4) is mounted between them. Above the discharge opening (4) is mounted a cut-off member (9) with a possibility of vertical and horizontal movement and has its surface extending in parallel with the disc (3) surface.

## Claims

### Claim 1

An apparatus for metering bulk materials comprising a vertically extending receiving hopper (1) having a guide funnel (2) in the bottom part thereof and at least one disk (3) with at least one discharge opening (4) extending along a substantial distance of a disk radius, the disk mounted for rotation about a vertical axis, between the hopper (1) and guide funnel (2); a cut-off member (9) arranged immediately above the discharge opening (4) of the disk (3), the cut-off member 89) is arranged vertically movable in relation to the disk and for horizontal movement with the disk and has a surface extending in parallel with the surface of disk (3).

### Claim 2 (depends on 1)

An apparatus according to claim 1, wherein the cut-off member (9) comprises a plate mounted on an arm (8) movably connected to the disk (3).

### Claim 3 (depends on 2)
