Rotary sifter for bulk material preparation

Ensure precise material preparation and protect downstream processes by integrating high-performance rotary sifting for effective separation and size reduction in continuous operations.

The RS Rotary Sifter from Zeppelin Systems is a robust solution designed for the efficient sifting and separation of bulk materials such as flour, starch, and plastic pellets across industries including food, plastics, and chemical processing. This equipment stands out with its compact design and dual-bearing construction, which ensures longevity and low vibration during continuous high-speed operations.

Employing a customizable sifter drum, available in mesh sizes from 0.25 mm to 8 mm, it efficiently removes foreign materials and optimizes particle size distribution. The RS Rotary Sifter integrates seamlessly into both pressure and vacuum pneumatic conveying systems, operating effectively under conditions ranging from -0.4 bar to 0.8 bar overpressure.

Fabricated with food-grade materials and certified compliant with EHEDG guidelines, it particularly excels in food industry applications, maintaining product safety and quality. Its automatic sifter drum monitoring feature (Screen-D-Tect) provides real-time detection of wear, preventing production disruptions. The optional ATEX-compliant version is suitable for hazardous areas, ensuring operational safety.

Maintenance is straightforward, with easy access for cleaning and drum replacement, minimizing downtime. Engineered for durability, the RS Rotary Sifter is an essential technology for ensuring product quality and process efficiency in demanding industrial environments.
