Dosing, Feeding, Discharging – Rotary Airlocks by Zeppelin Systems Keep Bulk Materials in Motion

Rotary airlocks from Zeppelin Systems ensure safe feeding into pneumatic conveying systems, relieve subsequent components under silos, and take on dosing tasks.

The broad range of airlocks 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 airlocks cover a wide range of uses beyond typical pressures and temperatures, and models with crushing functions or quick cleaning options are also available.

Main Advantages at a Glance:

• High Purity and Less Waste: The optimized inlet and outlet geometry gently transports the bulk material through the airlock.
• Lower Energy Costs and Gas Consumption: Due to the optimal and individually adjusted gaps between the rotary airlock and the casing, the airlocks operate extremely energy-efficiently.
• Long Service Life, Extended Maintenance Intervals, and Low Repair Costs: Unique and durable sealing systems ensure long-lasting performance.

In addition to the examples provided, our airlocks 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!

Food and Beverage

Typical applications include the feeding and discharge of flour and sugar in pneumatic conveying systems. Our airlocks 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.

Plastics

With our airlocks, 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 airlock 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 airlocks are designed with high to very high torque capacities to ensure a crushing function.

Chemistry

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.

Rubber & Tire

In tire manufacturing, in addition to base materials like carbon black and silica, many other additives are used. Zeppelin airlocks 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 airlocks with closed rotary airlocks are used.
