The screw batch charger is mounted on a movable cart. If the mixture is filled directly from the furnace day hopper in the charging hopper, the feeding hopper may serve as a transitional piece between the furnace hopper and charging machine. The mixture can also be transported via a screw conveyor or a vibrating chute, etc. and fed into the charging hopper.

On request, an electrical level sensor can be installed in the batch hopper, which forwards the signal to a dry contact. This contact can be used to control the screw conveyor or vibrating chute. The funnel spreads the mixture evenly over the screw. A water-cooled insert pipe and a screw conveyor are placed in the furnace wall and transport the batch into the furnace.

An insulated fixing ring which is installed at the pipe of the batch charger seals the opening within the furnace wall.
