Ribbon Blender
The Ribbon Blender is an industrial mixing device utilizing counter-rotating helical ribbons to achieve homogeneous blending of powders, granules, and viscous materials. It is widely applied in pharmaceuticals, food processing, and chemical industries.
Core components
Primary Ribbon: Outer diameter Φ800–3000 mm, clockwise rotation for outward material dispersion.
Secondary Ribbon: Counter-clockwise rotation for axial material convection.
Drive System: Variable-frequency motor (7.5–55 kW) + planetary gear reducer (gear ratio 25:1–50:1).

Selection Guide
Procurement Decision Framework
Define Application Requirements
| Parameter | Critical Questions |
|---|---|
| Material Type | Powders, granules, or viscous pastes? |
| Batch Size | 0.5–12 m³ (select fill factor 60–75%) |
Cost-Benefit Analysis
Capital Cost
Carbon steel: 1,000–4,000
Stainless steel: 2,000–50,000
Lifetime Cost
Energy savings: 8,000–15,000/year (IE4 motors + VFD).
Maintenance: 20% lower vs. paddle mixers due to fewer moving parts.
Safety Warnings
Explicit warnings and compliance references align with industrial regulatory requirements.
| Safety Warnings | Condition | Required Action |
|---|---|---|
| Overload Prohibition | Material bulk density >1.2 g/cm³ | Reduce fill rate to 50% |
| Static Control | Grounding resistance <4 Ω (combustible dust) | Maintain IEC 60079-0 compliance |
| Emergency Stop | Vibration exceeds 7.1 mm/s (RMS) | Trigger immediate shutdown |
Maintenance Protocol
Logical sectioning and bullet points enhance scanability for engineers and maintenance personnel.
Operational Procedures
Pre-Start Checklist: Verify ribbon-to-shell clearance ≥5 mm (feeler gauge measurement).
Lubrication: Replace gear oil (VG320) in reducer every 500 hours; inject NLGI 2 lithium grease into bearings monthly.
Wear Monitoring: Repair via hardfacing when ribbon thickness loss exceeds 10% (AWS A5.18 ER70S-6 welding wire).
Shutdown Maintenance
Execute Lockout-Tagout (LOTO) after power cutoff.
Dynamic balancing: Residual unbalance ≤2.5 g·mm/kg (ISO 1940-1 G6.3 grade).
