Product Details:

Product Brief

The KR-743 vertical dual-temperature high-speed blender is a standalone compounding unit dedicated to PVC resin dry blending, masterbatch homogenization and multi-additive plastic premixing. It integrates self-friction hot mixing and water-circulation cooling functions into one compact framework. High-speed impellers create strong three-dimensional vortex shear to fully disperse stabilizers, lubricants, colorants and fillers, while the built-in cooling barrel rapidly lower material temperature to eliminate agglomeration and volatile gas residues.
This series covers lab mini volumes to large industrial batches, fully configurable for profile extrusion, pipe production, cable compounding, coating powder and food powder processing lines. Equipped full PLC interlock safety control and pneumatic automatic discharge structure, it is widely adopted by plastic manufacturers, color masterbatch factories, polymer R&D labs and chemical raw material enterprises.

Core Unique Advantages

  1. High-Shear Multi-Angle Stainless Impeller Assembly
    Custom multi-layer mirror-polished mixing paddles with variable tilt angles generate 360° cyclic material flow inside the barrel, eliminating dead mixing zones. Thickened wear-resistant alloy blades resist abrasion from carbon black, calcium powder and mineral fillers; interchangeable paddle sets support small lab batches and heavy industrial formulations without cross-contamination.

    2.Dual Temperature Independent Regulation System

    Two optional heating modes: pure friction self-heating or auxiliary electric heating for low-filler materials. The matched cold mixing barrel adopts spiral water channel design for uniform rapid cooling, preventing hot PVC powder from clumping and moisture reabsorption after mixing. Separate PID modules precisely monitor hot/cold barrel temperatures to avoid polymer thermal degradation.

    3.Full Pneumatic Automated Operation Framework

    Pneumatic lifting sealing cover with double-layer silicone sealing strips blocks dust overflow and volatile leakage during high-speed stirring. Horizontal air cylinder quick discharge outlet realizes fully automatic material unloading without manual shoveling; transparent visual observation window allows real-time monitoring of mixing status without stopping the unit.

    4.Imported Sealing & Bearing Configuration

    All rotating shaft positions adopt PTFE composite sealing rings and anti-dust bearings imported from Europe, effectively blocking fine powder penetration into transmission components. Long service cycle without frequent seal replacement, drastically cutting daily maintenance downtime for continuous production lines.

    5.Central PLC Safety Interlock Control Cabinet

    Independent electrical control cabinet integrates speed adjustment, temperature monitoring, timing mixing and fault alarm functions. Multiple safety interlocks: cover opening power cut, motor overload protection, overtemperature automatic shutdown and emergency stop button, avoiding misoperation risks for workshop staff. All mixing process parameters can be stored and recalled for consistent batch quality.

    6.Modular Customizable Capacity Series

    Complete model spectrum from 5L lab small test machine up to 800L mass production model, supporting manual small discharge and large pneumatic discharge two structures. Frame size, motor power and cooling water pipeline layout can be customized to match extrusion, granulation and coating production line layout demands.

Standard Complete Mixing Operation Flow

  1. Pre-Operation Inspection

    Check cooling water pipeline connectivity, seal cover tightness and control cabinet circuit; clean residual powder inside mixing barrel to avoid batch cross-color pollution.

  2. Raw Material Feeding

    Open pneumatic cover, sequentially add PVC base resin, stabilizer, lubricant, pigment and inorganic fillers according to formulation ratio, then lock the sealed lid automatically.

  3. High-Speed Hot Mixing Stage

    Start main motor, high-speed paddles generate friction heat to disperse all additives evenly. PLC monitors real-time material temperature; automatically trigger transfer once preset mixing temperature and time are reached.

  4. Circulation Cooling Stabilization

    Hot material flows into the cold mixing barrel, spiral water channels rapidly lower powder temperature to safe storage temperature, removing residual low-molecular volatiles to prevent material agglomeration.

  5. Automatic Discharging

    Activate pneumatic discharge cylinder, fully empty cooled homogeneous powder into transfer hoppers for downstream extrusion, granulation or tableting procedures.

  6. Post-Batch Cleaning

    Wash barrel inner wall, paddles and discharge outlet with compressed air; replace sealing strips regularly for long-term stable operation.
