ZIPPE glass batch chargers for glass melting furnaces
ZIPPE glass batch chargers for glass melting furnaces are distinguished by excellent reliability, flexibility and technically irreproachable charging properties.
Glass batch chargers for plate glass applications
The use of several machines in one doghouse allows the stream of glass batch to be directed individually both in terms of direction and volume, thus making optimum charging of the furnace surface possible.
ZIPPE float glass chargers can be configured for all doghouse widths. There are no problems in retro-fitting the chargers to existing furnaces.
This glass batch charger makes it possible to charge batch onto the melting surface while avoiding a fall and thus also avoiding dust generation.
The pusher pivots from side to side allowing good directional control of the material flow and an even addition of batch onto the melting surface.
The design of the glass batch charger allows the doghouse to be sealed, reducing energy losses.
The standard glass batch charger features a particularly sophisticated and robust design combined with easy maintenance.
Parts in contact with the glass are water-cooled but, if particularly required, can be supplied in heat-resisting special steel without water-cooling.
In the case of furnaces with wide dogholes, for example in flat glass furnaces, several chargers can be used in parallel to each other across the entire width of the doghouse.
Charging through relatively small dogholes is possible because of this charger’s special design and the use of a heat shield while at the same time sealing the doghouse. Heat loss is reduced.
The output of the charger can be continuously regulated by the control signal of a glass level gauging system; alternatively it can be regulated at specific intervals.

This pot furnace charger has succeeded in mechanising the traditional manual charging of a pot furnace. The glass batch charger can be easily moved by hand and has been well designed for its task. The charging chute has a pneumatic drive.
The advantages of the pot furnace charger are a significant reduction in dust generation and poisoning hazards, no spillage of the molten glass, a consistent level in the pot furnace and a reduction in physical work for the furnace crew.
Glass batch chargers for other applications
The batch is moved from an intermediate silo into the feeding hopper of the glass batch charger. The batch is fed into the furnace via a vibrating chute driven by an air piston vibrator. The vibrating chute can be replaced by a conveyor belt for specific applications.
The charger moves both from left to right and from front to back during the charging process. The charging rate is adjusted optimally by a glass level control unit to meet the furnace conditions.

Screw conveyor chargers are suitable for charging all types of furnaces; a doghouse is no longer necessary. Several glass batch chargers are arranged parallel or opposite to each other in the case of large furnaces or high furnace outputs.
A particular advantage is that the furnace is completely sealed on the side used by the charger; this is a pre-requisite for furnaces where oxygen is used in the heating process. But it is also an advantage in conventionally heated furnaces due to energy conservation, dust avoidance and a constant hearth pressure .
