The cold top batch charger is used for electrically heated furnaces.

The batch charger is manufactured in a solid welded and screwed construction and runs in two axes – x and z – through two carriages. Each carriage is driven by a frequency controlled gear motor. In this way, the vibrating feeder moves just above the glass surface in the furnace and feeds parallel batch layers on top of the surface. Initiators monitor the positions of both axes of the charging machine.

The charging machine is equipped with a batch hopper and level detectors. When the hopper is nearly empty, the charger moves automatically to a filling and docking station to be refilled.
