Products Description
Need fast, homogeneous blending of powders or powders with small amounts of liquid?
Guanjiang’s Horizontal Ribbon Mixer delivers CV<5% mixing uniformityin just 3-10 minutes. Its unique ribbon blades create a three-dimensional material movement — pushing powders from both ends toward the center and vice versa — eliminating dead zones. Available with heating/cooling jackets, CIP cleaning, and GMP-compliant finishes. Ideal for chemicals, food, pharmaceuticals, and building materials.
Key Advantages of Our Horizontal Ribbon Mixer
High mixing uniformity with coefficient of variation below 5%. Unique ribbon design forces convection, shearing, and diffusion — no dead zones, no material residue.
Full-open butterfly valve or reverse ribbon rotation empties the U-shaped trough in seconds. Large batch capacity (loading factor 0.4-0.7) for medium to high-volume production.
Cantilever or double-support shaft design for easy maintenance. Robust bearings and seals withstand heavy starts and long-term operation — low failure rate, long service life.
Optional jacket for heating/cooling, spray nozzles for liquid addition, and CIP system. Electropolished stainless steel meets GMP standards for food/pharma.

⚙️ How It Works:
The motor-driven shaft rotates ribbon blades in a U-shaped horizontal trough. Outer ribbons push material from ends toward the center, while inner ribbons push from center toward ends. This creates a three-dimensional convective motion (radial + axial) that achieves macro and micro homogeneity faster than other mixer types.
Frequently Asked Questions About Horizontal Ribbon Mixers
Q: What is the difference between a ribbon mixer and a paddle mixer?
A: A ribbon mixer uses continuous spiral blades that create both radial and axial flow — ideal for powders and achieving CV<5% uniformity. A paddle mixer uses individual paddles that create mostly radial flow — better for fragile materials or when gentle mixing is required. We offer both; choose based on your material sensitivity and required uniformity.
Q: Can I add liquids (e.g., binders, oils) during mixing?
A: Yes. The mixer cover can be equipped with spray nozzles or a liquid addition system. Liquid is injected while the ribbons are rotating, allowing even distribution for wet granulation or coating applications. This is a common use in food, chemical, and pharmaceutical industries.
Q: How do you clean the mixer between different products?
A: For non-sticky materials, manual brushing and vacuuming may suffice. For frequent changeovers or GMP environments, we offer an optional CIP (Clean-in-Place) system with spray balls that clean the trough, shaft, and ribbons automatically. Electropolished surfaces also reduce material adhesion.
Q: Can the mixer handle abrasive materials without excessive wear?
A: Yes. We offer hardfacing or wear-resistant coatings on ribbon blades and internal surfaces. The heavy-duty shaft and bearings are designed for abrasive applications like minerals, pigments, and ceramic powders. Regular gap checks between ribbons and trough ensure consistent performance.
