A distributor device including a distribution chute (3) that extends inside the tank at an inclined angle (alpha) with respect to the vertical direction for distributing material in the interior of the tank (2). A rotation frame (4) is rotatable around a vertical central rotation axis (L) and includes an essentially vertical inlet channel (5) extending to the interior of the tank (2). The distribution chute (3) is attached to the lower part of said rotation frame, and said inlet channel (5) opens upwardly for receiving any gravitationally moving loose material and downwardly for discharging said loose material to the distribution chute (3) and through the distribution chute further to the tank (1). A circular support frame (6) is horizontally attached to the rotation frame (4), concentrically in relation to the vertical central rotation axis. A number of support rollers (7, 8, 9) are connected to the tank (1) so that the axes (10, 11, 12) of the support rollers are positioned radiallywith respect to the central rotation axis (L). Said support rollers (7, 8, 9) are arranged in contact with the support frame (6) for supporting the rotation frame on the support rollers, and for bearing mounting the rotation frame to be rotary in relation to the tank. An actuator (13) is arranged to rotate the rotation frame (4). At least one of the support rollers (7, 8, 9) is as a support roller (7) driving the rotation frame, which support roller the actuator (13) is arranged to rotate. The distributor device includes a counterweight (22) attached to the rotation frame (4), on the oppositeside of the central rotation axis (L) in relation to the distribution chute (3). The counterweight (22) is arranged to balance the rotation frame (4).
