Dosing and conveying screw for dry bulk materials
Efficiently manage the precise dosing and conveying of dry, powder, and pelleted materials, ensuring seamless integration into diverse production lines and boosting operational reliability.

Conveys and Doses Bulk Powders and Granulates
The DS Dosing and Conveying Screw ZSD, offered by Zeppelin Systems, is engineered for precision dosing and efficient transport of dry bulk materials across various industries, including food, chemicals, plastics, and rubber. This equipment stands out due to its stainless steel construction, ensuring durability and corrosion resistance, suitable for food-industry applications. The system uses a laser-cut screw flight design, facilitating high dosing precision through frequency converter adjustments, allowing easy adaptation to local conditions such as bulk material weight and output requirements.
Operational in both single- and dual-outlet configurations, it supports flexible integration within conveying systems for tasks like weighing, filling, or emptying vessels. The DS screw handles powders and granulates including flour, sugar, powdered milk, and even polymer and PVC granules. The robust design allows continuous, high-speed operations and includes features such as de-aeration, quick cleaning with EHEDG compliance, and lifelong bearing lubrication for minimal maintenance.
With ATEX conformity and EC type examination certification, this equipment meets stringent safety standards. Customizable options such as the inclusion of sealing gas for extended bearing life and the option for integrated speed monitoring sensors ensure that it meets specific operational demands. Whether for integrating into existing lines or forming part of new systems, the DS screw offers reliable performance for enhanced productivity.
