Rotary Drum Granule Mixer: High-Efficiency Equipment for Granular Material Blending

In the production processes of food, pharmaceutical, chemical, and feed industries, uniform mixing of granular materials is crucial for product quality and consistency. The Rotary Drum Granule Mixer, with its advantages of simple structure, stable operation, and high mixing uniformity, is widely used in various granular material processing production lines, delivering reliable performance across diverse industrial applications.

Working Principle & Design

• Tumbling Action Mixing:
  The drum rotates at an optimal speed (typically 15-25 RPM) causing granular materials to cascade and tumble in a three-dimensional mixing pattern. This gentle action ensures thorough blending without material degradation or segregation.

• Cylindrical Drum Design:
  The horizontal cylindrical chamber provides maximum mixing volume efficiency. Internal baffles and lifters can be customized to enhance mixing action for specific material characteristics and improve blend uniformity.

• Variable Speed Control:
  Precision speed control allows optimization for different material densities, particle sizes, and mixing requirements. Lower speeds prevent attrition of fragile materials while higher speeds accelerate mixing of dense products.
