Industrial rotary sifter for bulk materials
Ensure precision and quality in your production line with a robust solution designed to efficiently sift and filter bulk materials, removing contaminants and verifying grain sizes for consistent end-product quality.

Screens and Verifies Bulk Material Consistency
Zeppelin Systems’ RS Rotary Sifter and TS Drum Screen are engineered-to-order screening machines that excel in quality control for bulk material processing. They utilize a robust rotary sifting mechanism and specialized drum screens to separate contaminants and verify particle size in continuous operations. Widely adopted across the food, plastics, carbon black, and rubber industries, these systems handle materials such as flour, polyethylene pellets, and tire crumb rubber with precision. The RS Rotary Sifter ensures reliable inline sifting with options to withstand up to 0.8 bars of overpressure or vacuum in pneumatic conveying lines, while both units allow for mesh customization between 0.25 mm and 8 mm. Featuring automatic drum monitoring with Screen-D-Tect and potential for in-situ cleaning, these machines are also designed in compliance with ATEX Directive 94/9/EC for operations in explosive atmospheres. The use of durable materials like polyester and VA stainless steel alongside easy maintenance access makes them an optimal choice for purity-critical and high-throughput environments, with customization options available to fit specific production line requirements.
