U Shape Horizontal Ribbon Mixer High Precision Double Ribbon Blender

1. Mainframe Framework

   • U-shaped mixing chamber: Symmetrical streamlined design minimizes material residue and facilitates cleaning.
   • Double helical agitators: The outer helix (larger diameter) and inner helix (smaller diameter) work synergistically to create a three-dimensional mixing field.
   • Drive system: Equipped with frequency-adjustable motors, supporting 0-60rpm speed adjustment to accommodate different material properties .

2. Innovative Transmission Mechanism

   • Outer helix (clockwise rotation): Transfers raw materials from both ends to the center, generating axial flow.
   • Inner helix (counterclockwise rotation): Counteracts by pushing materials from the center to the ends, achieving shear mixing.
   • Reverse motion ratio: Typically, the outer helix rotates 1.5-2 times faster than the inner helix to balance turbulence and homogeneity .

II. Modular Design Characteristics

1. Adjustable Agitator System

   • Standard helical blades: Suitable for free-flowing powders (e.g., flour, chemical granules).
   • Toothed blades: Enhances shear force for high-viscosity materials (e.g., adhesives, silicone).
   • Digging blades: Designed for bulky materials (e.g., fractured polymers) to improve fragmentation efficiency .

2. Auxiliary Functional Configurations

   • Chopper unit: Optional dual-blade cutter operates at 1200rpm to break agglomerates.
   • Sealing system:
     • Concave top cover: Supports 0.5MPa positive/negative pressure for flammable/explosive media.
     • Quick-opening end cover: Hydraulically lifted in 30 seconds for easy cleaning.
   • Temperature control: Jacketed heating/cooling system with ±1℃ precision for heat-sensitive materials.

III. Performance Advantages (Quantitative Analysis)

IV.  Technological Development Trends

1. Intelligent Upgrades

   • In-line monitoring: Near-infrared spectroscopy (NIR) for real-time mixing analysis.
   • Digital twin: CFD simulation to optimize agitator flow fields.

2. Green Manufacturing Adaptation

   • Low-shear mode: Reduces oxidation degradation of heat-sensitive materials (e.g., vitamin C).
   • Modular cleaning: Ultrasonic-assisted systems cut water usage by 60%
