## Abstract

A discharging device for mills, comprising: a conduit (10), structured so as to be connected to a discharge opening (3) of a mill (1); a bend (11) disposed along the conduit (10), which defines a curve of the conduit (10); a regulating device (12) associated to the bend (11) and predisposed for varying the position of the bend (11) so as to vary at least a height thereof.

## Claims

### Claim 1

A discharging device for mills comprising:
a conduit (10), which is configured to be connected to an outlet opening (3) of a mill (1); a bend (11) disposed along the conduit (10), which defines a curve of the conduit (10); a regulating device (12) associated to the bend (11) and predisposed for varying the position of the bend (11) so as to vary at least the height thereof;
wherein the regulating device (12) is configured for rotating at least one intermediate stretch of the conduit (10) comprising the bend (11) about an axis of rotation (X);
wherein the axis of rotation (X) is aligned with the outlet opening (3) of the mill (1).

### Claim 2 (depends on 1)

A discharging device according to claim 1, wherein the regulating device comprises a circular-arc shaped guide (13), which is concentric with the axis of rotation (X).

### Claim 3 (depends on 2)

A discharging device according to claim 2, wherein at least one portion of the conduit (10) is slidably associated to the guide (13).

### Claim 4 (depends on 1)

A discharging device according to claim 1, wherein the regulating device (12) comprises an actuator, associated to the intermediate stretch of the conduit (10) comprising the bend (11), so as to rotatingly activate the intermediate stretch about the axis of rotation (X).

### Claim 5 (depends on 1)

A discharging device according to claim 1, comprising a separator (14) which is arranged to allow separation of solid objects from a fluid flowing along the conduit (10).

### Claim 6 (depends on 1)

A discharging device according to claim 1, wherein a separator (14) comprises a container placed in communication with an initial stretch of the conduit (10).

### Claim 7

A mill for the grinding of a substance comprising a substantially cylindrical-shaped casing (1) and rotating about an axis of rotation (X); an inlet opening (2) being concentric to the axis of rotation (X); an outlet opening (3) being concentric to the axis of rotation (X); wherein the mill further comprises a discharging device;
wherein the discharging device comprises a conduit (10), which is connected to the outlet opening (3); a bend (11) disposed along the conduit (10), which defines a curve of the conduit (10); a regulating device (12) associated to the bend (11) and predisposed for varying the position of the bend (11) so as to vary at least the height thereof;
wherein the regulating device (12) is configured for rotating at least one intermediate stretch of the conduit (10) comprising the bend (11) about the axis of rotation (X);
wherein the axis of rotation (X) is aligned with the outlet opening (3).

### Claim 8 (depends on 7)

A plant for the grinding of one or more substances, comprising two or more mills (1) according to claim 7, which are connected in parallel to an inlet manifold (A).
