Claims15
A device for dosing, or weighing, or dosing and weighing bulk material comprising at least one bulk material shut-off element, the bulk material shut-off element being operable by at least one electromechanical actuator, wherein the operation of the bulk material shut-off element is an opening or closing or opening and closing thereof, said bulk material shut-off element being a pivoting flap and being operatively connected to at least one load cell, so that a weight of accumulated bulk material can be determined with the flap in a closed position, and
- wherein the electromechanical actuator comprises:
- an electric motor,
- control and drive electronics assigned to the electric motor, and the electromechanical actuator comprises capacitors, which are configured and arranged to act as a buffer that bridges peak power demand when actuating the actuator.
