Advantages of QT4-15 concrete block making machine 

HENGDA Automatic Block Making Machines:

Our machines, with harmonic cooperation between mechanical, electrical and hydraulic machines functions, guarantee a reliable and high output production of concrete products

1. Use LG PLC control system and Touch Screen, use TOP BRAND relays and contactors:

    A. LG PLC, with great adaptability, guarantees the stability and reliability of the machine.

    B. Visualization touch screen, with easy operation;

    C. High-quality electrical components;

2. Use Frequency Conversional Control Technology, which controls the block making:

    A. Frequency Conversion Control: guarantees the precise and parallel movement between tamper head and mould   protects the products from transfiguration; increases the production rate by improving the vibrating efficiency;

    B. Controls the instantaneous start and stop of the motors, to protect the motor from over-heating caused by constant working;

    C. Power saving: 30%;

3. Use double high-dynamic Proportional/Directional Valves to automatically adjust the oil flow and pressure

    A. Buffer the hydraulic cylinder, to protect the cylinder from damage caused by inertia;

    B. Guarantee production stability;

4. 360° Multi-Shaft Rotating and Compulsory Feeding:

    A. Speedy and rotating feeding, with uniform mixing, to make sure that the density and intensity of the products are guaranteed

    B. This uniform feeding is applicable for different kinds of raw materials and moulds;

5. Use heat treatment on moulds and main parts of the machines:

    A. Heavy duty machine structure and wear resistant moulds;

    B. The hardness reaches up to HRC 52-58;

C. Greatly improves the using lifetime of the machine by 50%.
