1. Overview

The Vertical High Speed Mixer is a high-performance mixing system designed for heating, cooling, and uniform blending of PVC, plastic granules, and chemical powders.
It integrates hot and cold mixing stages in one unit, ensuring rapid and efficient processing while maintaining consistent quality.

Widely used in plastic compounding, masterbatch production, polymer modification, chemical, and food industries, it improves productivity and product stability.

2. Working Principle

The mixer operates through a two-stage hot and cold mixing process:

• Hot Mixing Stage: High-speed blades generate frictional heat to soften and disperse additives uniformly. Temperature control prevents thermal degradation.

• Cold Mixing Stage: The material is cooled using circulating water, stabilizing it and preventing moisture absorption or agglomeration.

• Discharge: The cooled, homogenized mixture is ready for extrusion, granulation, or molding.

3. Operating Process

1. Preparation: Ensure the machine is clean, water supply connected, and electrical system ready.

2. Feeding: Load PVC resin, stabilizers, colorants, and additives into the hot mixer.

3. Hot Mixing: Set the speed and temperature. Mix until uniform.

4. Cooling: Transfer to cooling mixer; reduce temperature quickly.

5. Discharging: Release the cooled mixture for downstream processing.

6. Cleaning & Maintenance: Clean the chamber and blades after each batch.
