Batch Charger Type VIBROTUBE®
The VIBROTUBE® is our new low emission, low wear charger for container glass. It fully encloses the doghouse and has dust-free encapsulation, and so has an extremely low NOx emission level. With its vibrating conveyor tubes, the batch is transported into the melting furnace virtually without contact, a process that reduces wear considerably.
The two pushers split into small portions the batch fed into the melting furnace. The larger contact area of the batch and the heat give rise to optimised melting. The pushers are driven by a servo geared motor with continuously adjustable control. This means stroke length and speed can be adjusted individually to the desired requirements.
The following benefits are distinctive features of the VIBROTUBE®:
- Complete sealing of the doghouse
- Minimisation of wear
- Perfect adjustment to production conditions
- Energy saving through optimised batch behaviour
Batch Charger Type ECD
This batch charger enables batch to be added to the melt surface without a drop height. This prevents dust from building up.
The turning motion of a pusher means specific direction control of the material flow is possible, and so uniform distribution over the melt surface.
The batch charger design is such that the doghouse is sealed. This prevents energy losses.
Batch Charger Type EVP
Its special design and use of a heat shield mean charging into relatively small openings is possible whilst retaining the doghouse seal. Thermal loss is reduced.
The capacity of the batch charger can be controlled continually or discontinually by the control signal of a glass level controller.
Batch Charger Type E
A particular sturdy and mature design, and simple maintenance, are stand-out features of the standard batch charger.
Parts coming into contact with the glass are water-cooled, or (for special requirements) can be made of special heat-resistant steel without water cooling.
For melting furnaces with wide charge openings (e.g. for flat glass furnaces), several batch chargers arranged in parallel across the overall width of the doghouse are deployed.
Batch Charger Float Glass
The deployment of several machines in one doghouse means that the batch flow can be controlled individually in terms of direction and quantity. This means optimal allocation of the melt surface is possible.
ZIPPE flat glass batch chargers can be designed for all doghouse widths.
Freely selectable fill volume of the furnace silo depending on the height available. Every individual machine can be retracted quickly in an emergency. The time overhead is only about 20 minutes for trained personnel.
The stroke length is continuously variable from 0 to 250 mm. The speed of the chute can be set separately.

Screw Charger
Screw chargers are suitable for feeding all furnace types - a doghouse is not required. For large furnaces and/or when corresponding performance is required, multiple batch chargers are arranged in parallel or opposite each other.
A particular benefit is that the furnace is completely sealed on the charger side; this is a prerequisite for furnaces heated with oxygen. But also for furnaces heated in the conventionally way, it has benefits in terms of energy savings, dust prevention and constant pressure.
Pot furnace charger
Traditional pot furnace manual feeding was mechanised years ago with the proven pot furnace batch charger. The batch charger is easy to move by hand and has a practical design. The charger tray is driven pneumatically. The benefits of the pot furnace batch charger are high reduction of dust build-up and risk of intoxication, no spillage of the molten material, more uniform fill level of the melting pot, and easier physical work for personnel.
