Till now, our automatic block making machine is available with QT4-15B series, QT4-15C series, QT6-15 series, QT6-15B series, QT8-15 series, and QT10-15 series. It has been certified by CE, SGS, TUV, and the like. Our machine has been approved by Bureau Veritas, TUV CERT.


1. Mainframe
The automatic block making machine applies the high-strength structural steel and special welding technique for its mainframe. The firmness of the mainframe allows the whole machine to come with good rigidity and vibration resistance.
2. Guide Pillar
The guide pillar of this machine applies the ultrastrong special steel. By virtue of the chromate plated treatment, it perfectly resists torsion and abrasion. Additionally, the four guide pillars together with the ultra-long guide bearing make the pressure head and mould move accurately. This moving system adopts the special device that is good for lubrication, thus avoiding abrasion.
3. Material System
The crane of the material machine is controlled by the hydraulic system. That its hopper is connected to the crane by the rubber spring, can offer favourable damping effect while preventing the vibration compaction of the remained materials. In the system, the hopper is equipped with a door which can help realize the uniform material distribution.
4. Material Distributing System
In this system, the material storage and distribution are independent from each other. The material receiving in the material box is accurately controlled. Under the function of the powerful centrifugal force, the material is speedily and evenly distributed.

2. How does Automatic Block Making Machine work?

1. Screw Conveyer (Optional fitment): loading bins of the instrument for transporting Fly Ash from the silos(optional fitting) or cement hopper (optional fitting) to the Batching Plant.

2. Batching Plant: It consists of three loading bins and one weighing bin. It also contains blet conveyers to convey materials from loading bins to weighing bin. Batching and weighing is done by PLC control. We can load three different types of material into the loading bin.

3. Conveyer Belt: When the Batching plant's weighing bin trips according to the PLC control, the material comes to this conveyer belt. Then conveyer belt carried materials to the Mixture Machine. 

4. Concrete Mixture Machine: All the ingredients are mixed in this mixture machine. Mixing time and speed is controlled by PLC. The inbuilt water pump adds water to the mixer automatically, as per requirement. 

5. Block mold machine: This is key of the production line. It can press the mixed material. So it can make various hollow block, solid brick, paver brick and kerbstone.

6. Stacker: Stacker is used to lay the block automatically, which is high-efficient and labor saving.
