This batch charger consists of a fixed-mounted base and a movable upper structure with a charging hopper. If the hopper is filled by means of a vibrating chute, an electrical level sensor in the hopper is used.

A hydraulically actuated piston presses the batch with shards through the water-cooled insert attachments into the furnace. The frequency of the piston movement can be regulated by the signal of the glass level measurement or by time control.

The stroke of the piston can be set by two non-contact, adjustable limit switches.

A broken glass size of 50 mm edge length must not be exceeded. Larger pieces of glass could get between the front edge of the piston and the front edge of the squeezed transition hopper and cause increased wear.

The fine dust is extracted through a dust removal unit. After a coarse separator the dusty air also passes through several fine filters.
