The Glaß & Wolff dosing gate is a locking flow-regulating gate. Flow-regulating gates are predominantly installed in deep channels below the base. The cross-section of the flow aperture changes with the lifting drive, whereby the flow rate can be regulated.
The secondary engine is necessary in order to prevent clogging of the open flow surface with large quantities of beet. The gate is set into a small oscillating motion through a special joint, connected to the lifting drive. Blockages in front of the gate are prevented by means of a special displacement bracket.
The simple construction of the gate duct means that the depth is unlimited. The motor and joint units are built on the channel wall for easy access.
