Screw belt mixer for dry materials
Achieve uniform mixing of bulk dry materials with variable speed control, ensuring precise blending for optimal product consistency while preventing contamination through a sealed design that eliminates oil leakage into the mixing area.

Blends and Mixes Bulk Materials Efficiently
The Screw Belt Mixer SBM/SBM-K is a robust solution for industries such as rubber, food, plastics, and chemicals, designed by Zeppelin Systems. It efficiently blends bulk materials with densities between 0.5 and 0.7 g/cm³ using a ribbon blender mechanism within a stainless steel hopper. The mixer operates with no internal sealing elements, minimizing contamination risks, while the flat-drive motor with reinforced bearings accommodates high axial and radial forces. Optional variable speed control ensures adaptable mixing speeds for batch or continuous operations, creating an upward and downward flow for thorough 3D mixing.
This equipment is ideal for producing uniform rubber compounds, granola clusters, and high-performance coatings. Its design facilitates easy cleaning via a side-mounted inspection door, and the oil-leak indicator prevents contamination within the mixing area. Integrated with standard load-cells or support frames, the SBM/SBM-K offers seamless integration into existing production lines. Custom options, such as material and rotor speed configurations, ensure flexibility to meet specific project requirements, while maintaining energy efficiency and reliability across various applications.
