Dosing, Feeding, Discharging – Rotary feeders by Zeppelin Systems keep bulk materials in motion. Rotary feeders from Zeppelin Systems ensure safe feeding into pneumatic conveying systems, discharge bulk material under silos and containers and perform dosing tasks.
The broad range of feeders from Zeppelin Systems offers the right solution for every application. This starts with small throughputs of 2.8 liters and goes up to volumes of 400 liters, covering pressures up to 3.5 bar(g) and temperatures up to 180°C. Additionally, Zeppelin Systems offers solutions for non-standard applications. For example, our process feederss cover a wide range of uses beyond typical pressures and temperatures, and models with crushing functions or quick cleaning options are also available.
In addition to the examples provided, our rotary feeders can also be used in other industries. Feel free to contact us to discuss whether our airlocks can be applied to your specific application – We Create Solutions!
Typical applications include the feeding and discharge of flour and sugar in pneumatic conveying systems. Our rotary feeders also safely feed and discharge bulk materials in animal feed production. The sizes 160-320 feature particularly narrow gaps to reduce leakage. All plastic seals are food-grade certified.
With our rotary feeders, a wide variety of plastic powders and granules, such as polyolefins, compounds, and engineering plastics, are fed in and discharged to subsequent systems. The different variants are precisely tailored to your application. For example, there is a rotary feeder variant optimized for recycled plastics such as shreds, flakes, or film scraps. For very soft or very hard granules, an inlet variant with a spill plate is available. Our process rotary feeders are designed with high to very high torque capacities to ensure a crushing function.
In this industry, the biggest challenges lie in handling powders. For example, there are abrasive bulk materials that range from easy to difficult flowability. Special surface coatings are available to address this. Additionally, a quick-cleaning variant is offered to avoid contamination between different products.
In tire manufacturing, in addition to base materials like carbon black and silica, many other additives are used. Zeppelin Systems rotary feeders ensure optimal feeding of these materials into pneumatic conveyance systems with bypass systems and safe discharge of additives. A sealing gas system protects the bearings from ingress of bulk materials. For high pressures, high-pressure rotary feeders with closed rotary airlocks are used.
Medium pressure rotary feeder for the feeding and discharge of powders and granules in pneumatic suction and pressure conveying systems, which replaces the older rotary feeder models “A-type” & “AG/AP” with optimized features.
Through-Flow Rotary Feeder, preferably for feeding powdery bulk materials into pneumatic conveying systems, wherein the bulk material is fed directly into the conveying line without a feed shoe
High-pressure rotary feeder, preferably for the feeding and discharge of bulk materials in pneumatic suction and pressure conveying systems. The rotary feeder can not only be operated at high pressures of up to 3.5 bar(g), but can also be used as a chopping or quick-cleaning version.
Medium-Pressure Rotary Feeder, preferably for the feeding and discharge of bulk materials in pneumatic suction and pressure conveying systems
Process Rotary Feeder is mainly used for feeding and/or discharging powders and agglomerates bellow discharge vessels. Thanks to its special design, the rotary feeder allows high torques and crush agglomerates.

Dosing & Conveying screws
The dosing and conveying screws from Zeppelin Systems dose and transport bulk materials of all kinds. Additionally, they are also suitable for precise scale filling. The screws can be optimally adapted to the specific application. For example, a hygienic version with quick cleaning is available for baby food production, as well as dust-tight versions for handling powders.

Sampler
When it comes to securing the production process, or evaluating the quality of the final product, representative samples of the bulk material must be taken. Sample takers from Zeppelin Systems provide safe sampling of flowable powdered or granular bulk materials from silos, containers, downpipes, or pneumatic conveying systems. The sample can be taken under normal atmospheric conditions or within a pressure range up to 1 bar(g).
