The present invention relates to a method and to an arrangement for controlling the flow of crushed material from a hopper or like storage tower, the outflow opening is adjusted by adjusting the position of a swing gate (6). In accordance with the invention, the swing gate (6) is adjusted to a partially or fully open position, in dependence on the flow characteristics of the material in the hopper, and this set position of the gate is then maintained during the whole of the material discharge process and the speed of a variable speed conveyer belt (9), located at a short distance beneath the lower defining surface of the gate (6) in the fully open position of the gate, is varied in order to control the outflow of material. |
