When it comes to controlling suppliers, 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 in a pressure range up to 1 bar(g).

Zeppelin Systems offers two differently operating samplers that differ in how the sample is taken: either the bulk materials are extracted discontinuously/batch-wise from a container or downpipe, or the sampling is continuous. All samplers are available in different sizes and can also be used at higher temperatures and pressures.

Your Main Advantages at a Glance

• High Purity: All surfaces that come into contact with the bulk material are made of stainless steel
• Flexible Installation Position: The sample can be taken from a stationary or moving column of bulk material. With the GC type sampler, a sample can even be taken from a pneumatic conveying system in a pipeline.
• Long Service Life, Extended Maintenance Intervals, and Low Repair Costs: Unique and durable sealing systems ensure a long operational lifespan.
• Standardized products with a short delivery time.

Food and Beverage

Typical applications include steering bulk material flows such as flour, sugar, and salt in downpipes or pneumatic conveying systems. Various bulk materials in the animal feed sector and other applications are also directed using the diverters. Special attention is given to good cleanability and minimal material carryover:

• Seals made of plastic therefore have the appropriate food-grade certification.
• In the food industry, all product-contacting surfaces are generally made of stainless steel.

Kunststoffe

Plastic powders and granules, such as polyolefins, compounds, and engineering plastics, are conveyed and redirected into different directions using diverters. To ensure this happens as gently as possible without abrasion, Zeppelin Systems offers interesting variants:

• For high-quality powdered or granular bulk materials, various sealing options are available.
• Shock-free Internal Contours prevent unwanted material stresses that could cause abrasion in the form of powder or angel hair.
• Generally, the interior rotors in pipe diverters feature a stainless steel pipe insert. The flange necks of the pipe diverter housings can also be equipped with stainless steel pipe inserts upon request.
• Additional weatherproof covers, with or without heating, allow the use of pipe diverters even at extremely low ambient temperatures.

Chemie

In this industry, handling powders, which can range from easily to difficultly flowable and often abrasive bulk materials, can be challenging. However, Zeppelin Systems offers numerous solutions to safely guide even the most demanding products in the right direction.

• For very abrasive bulk materials, inflatable seals are available.
• In certain applications, additional purge gas units prevent powdered, abrasive materials from settling between the interior rotor (rotor) and housing in the sealing area.
• For highly abrasive materials, diverters with hardened stainless steel pipe inserts or diverters with ceramic lining are also available.
• The sticking of very sticky bulk materials, such as pigments, can reliably be prevented with flexible hose diverters.
• When using seals on the inside of the housing, all three pipe outlets can be sealed simultaneously. This also prevents reverse pressure on the non-activated pipe outlet.

Gummi & Reifen

In tire manufacturing, the base materials are typically carbon black and silica, along with possible additional additives. Zeppelin diverters ensure reliable bulk material redirection in pneumatic conveying lines with bypass systems. There are various options available:

• For tire carbon blacks, aluminum castings, hard-coated as standard, are used for the diverter housing and interior rotor (rotor), which significantly reduces the adhesion of carbon black.
• Typically, gland packing seals are used as static seals on the interior rotor.
• For highly adhesive technical blacks (pigments), flexible hose diverters are also used
