The Zeppelin Group As the direct successor of Count Ferdinand von Zeppelin who turned the human dream of flying into reality by building his legendary airships over a century ago, we are used to looking ahead. Constantly innovating, striving for perfection and maximum functionality in our products has turned us into the company that Zeppelin is known as today: the technology leader for handling premium bulk solids. > The industry sector of the Zeppelin Group is among the lead-ing manufacturers of plants for storing, conveying, blending, and dosing of premium bulk solids. Thanks to our...

Zeppelin has been the leader in the international market of silo construction for decades. Thanks to our own modern manufacturing and the international experience of our assembly staff and service engineers we guarantee quality of the highest level. Pulling all the strings: the central office for the industry sector is located in Friedrichshafen, Germany. Here, in the worlds largest Technol- ogy Center for pellets and powders, tests are carried out on an industrial scale. The test results are available to all subsidiaries, therefore allow- ing our clients to always be on the safe side і no...

For high demands regarding the pellet quality, the pneumatic dense phase conveying is normally used. This system is recommended especially for products susceptible to abra-sion. The dense phase conveying is more complex than the dilute phase conveying, is operated with higher pressures (up to > D e n s e p h a s e c o n v e y i n g typically 3.5 bar) and it requires more complex components regarding design and layout. However, the dense phase conveying is often the better solution for short conveying distances. > Conveying capacity Typical velocity: 3 ֖ 10 m/s Typical load: < 80 > Conveying...

For hydraulic conveying, water is used as conveying medium instead of gas.

Furthermore, smaller pipe diameters can be used even for high conveying capaci- ties, resulting in minimal pipe forces and low sound emissions. > Conveying capacity Conveying distance Long conveying distances an extremely demanding product: a...

Two special bypass systems (Overflow and Airfloat) allow the use of the gentle dense phase conveying even for fine powders. The bypass systems blow secondary air through valves into the conveying pipes at exactly defined intervals. This process ensures trouble-free dense phase conveying, a method which is preferably used for > bypass pressurespring force conveying pressureThe forces of the conveying pres-sure and the adjustable spring are balanced with the bypass pressure. If a plug passes the Overflow valve, the line pressure within the plug decreases and bypass air is injected through the...

The reliability of a complete system depends on the quality of its components You not only get field-proven products but also components designed to fit perfectly into the system ֖ for any application: for powders or pellets, for high or low pres- sures, for products with good or poor flow- ability, for standard or special applications (e.g. pipe cleaning systems). A broad range of products full of innovative and economic ideas. therefore, Zeppelin develops and produces the most important components in-house. This is the only way to guarantee process reliability for the whole plant. >...

Quality assurance Our Technology Centers are built on an industrial scale to meet our customers wide range of demands. Two separate test facilities are available at present: one for pellets and one for powders. We can provide you with tailored answers to your individual tasks, from trials on an industrial scale to special configurations that can be quickly installed. With our test facility network і unique in size, possibilities and performance we offer another element which will contrib- ute to your success: factual information on your product to help you select the best possible...
