Design and Operating Principle of the Spiral Concrete Mixer

1. Mixing Chamber

🔹 Made of wear-resistant steel and covered with replaceable protective plates.
🔹 Equipped with special spiral blades rotating in opposite directions.

2. Spiral Mixing Mechanism

🔹 Blades arranged on a spiral trajectory ensuring multi-flow mixing.
🔹 Generates turbulent movement that provides fast and uniform mixing.
🔹 Minimal wear of mixer components thanks to optimized blade inclination angle.

3. Drive System

🔹 Powerful electric motor with gearbox providing stable and uninterrupted operation.
🔹 High power enables mixing even dense and stiff mixtures.

4. Discharge Mechanism

🔹 Special sealed gate that prevents material losses.
🔹 Option for adjusting the discharge speed of the finished concrete.

5. Automatic Control System

🔹 PLC controller for programming mixing parameters.
🔹 Touchscreen display for monitoring speed, time, temperature, and humidity.
🔹 Remote control via mobile app or PC.
