WDH Horizontal Ribbon Mixer

Horizontal Ribbon Mixer Explained

I. Working Principle
The core of the horizontal ribbon mixer is a U-shaped cylinder + double-layer counter-directional ribbon stirring shaft. It achieves efficient mixing through a three-dimensional composite motion of convection, diffusion, and shearing:

Axial Convection: The outer ribbon pushes material from both ends of the cylinder towards the center, while the inner ribbon pushes material from the center towards both ends, forming a strong counter-current convection cycle.

Radial Diffusion: The rotating ribbon drives the material to flow radially along the cylinder wall and shaft, quickly breaking up component gradients.

Microscopic Shearing: The discontinuous ribbon generates localized vortices and shear forces, breaking up material agglomerates and achieving uniform diffusion of trace components.

Discharge: A discharge port is located at the bottom center. The rotating outer ribbon pushes the material to the discharge port, ensuring fast and thorough unloading.

II. Equipment Introduction

Structural Components: U-shaped horizontal cylinder, double/triple-layer counter-rotating ribbon agitator, cycloidal pinwheel reducer, motor, pneumatic/manual discharge valve, jacket (optional heating/cooling), observation and maintenance door, etc.

Specifications: Common WLD series, volume 0.1–30m³, material options include carbon steel and 304/316L stainless steel (food/pharmaceutical grade).

Operating Parameters: Loading coefficient 0.7–0.9, mixing time 3–15 minutes, mixing uniformity CV value 3–4%, capable of handling materials with a 1:10000 ratio.

III. Core Features

High Mixing Efficiency: Fast speed and high uniformity, 6–10 times more efficient than ordinary mixers, suitable for materials with high proportions of variation.

Wide material adaptability: Suitable for solid-solid (powder/granules), solid-slurry (powder + small amount of liquid), and viscous/paste materials, with minimal particle breakage.

Large loading capacity and low energy consumption: High filling coefficient, low power consumption, stable operation, and low noise.

Clean discharge and easy cleaning: Large bottom opening/butterfly valve discharges materials without residue; smooth inner wall with no dead corners, meeting hygiene standards.

Strong functional expansion: Can be equipped with heating/cooling jackets, liquid spraying devices, vacuum/positive pressure structures to meet special processes.

Easy maintenance: Compact structure, few vulnerable parts, direct-drive reducer, and low failure rate.
