A-type rotary feeder for powder and pelleted bulk materials

Ensure precise feeding and discharging of powdered and pelleted materials in pneumatic systems with robust, customizable rotary solutions designed for optimal flow control and minimal gas leakage.

Feeds and Discharges Bulk Materials Efficiently

The A-type Rotary Feeder ZSD from Zeppelin Systems is engineered for precise feeding and discharging of powdered and pelleted materials in pneumatic and vacuum conveying systems. Designed for industries such as food, plastics, rubber, and chemicals, it operates effectively under high differential pressures of up to 1.0 bar(g). Its unique 10-chamber rotor minimizes gas leakage while ensuring robust performance with a durable ribbed cast housing. Available in multiple sizes (160–500), it offers customizable configurations including quick cleaning and flameproof options certified under ATEX 2014/34/EU. The feeder is constructed for low maintenance, featuring integrated leakage-gas nozzles and sealed shaft passages. Suitable for diverse operations, it maintains mechanical integrity across a wide temperature range (-10 to +60°C). Compliance with DIN 2501 and ANSI standards is guaranteed, making it a versatile addition to your production line.
