Product Description
Concrete block production machine is a kind of equipment which uses slag, fly ash, stone dust, sand, gravel, cement and others as raw material, through material proportion, stirring and high-pressure moulding to make many kinds of bricks and blocks. It is also called non-burn brick machine. That's to say, the finished brick can come into use only through drying by the solar power, no need sintering.

Our Advantages
Our interlocking block making machine , with harmonic cooperation between mechanical, electrical and hydraulic machines functions, guarantee a reliable and high output production of concrete products
Use LG PLC control system and LG Touch Screen,
   A. LG PLC, with great adaptability, guarantees the stability and reliability of the machine.
    B. Visualization touch screen, with easy operation;
   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 doubles 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%.
