2.6m long conveyor machine
3.Block stacker machine
4.3Ton Wheeled Diesel Powered Forklift


What is the most suitable concrete mixer for QT4-20 automatic block making machine?
Henry QT4-20 can produce 900 pieces of 400*150*200mm concrete hollow bricks per hour, each brick weighs about 13kg, so it needs about 12,000kg of materials per hour. JQ500 concrete mixer can mix 500kg of materials every 2 minutes, so it can mix 15,000kg of materials every hour. Therefore, JQ500 mixer can completely meet the production needs of QT4-20 automatic concrete block making machine.
What can the conveyor machine bring to QT4-20 automatic concrete block making machine?
A conveyor machine can transport materials continuously and stably, improve production efficiency, operate automatically, and be easily controlled by switching on and off.


Why brick stacking machine is an indispensable necessary equipment for QT4-20 block making machine ?
1. The brick stacking machine can accurately stack concrete bricks through the automatic control system, which ensures the continuous and stable operation of the whole QT4-20 block machine production line. As HENRY QT4-20 is automatic machine and run quickly, once finished cement blocks are formed out , the stacking machine can stack finished wet block onto pallets to be four or five stories for carrying out by trolley .
2. Protective nets are installed on both sides of the brick stacking machine to ensure the safety of the production line and reduce potential safety hazards.
Every fully automatic concrete block machine site should be equipped with a forklift.
1. The forklift can quickly transport the stacked concrete bricks to the designated location.
2. The forklift is flexible, and it can not only transport bricks, but also undertake various handling operations on the construction site.
3.henry forklift is powerful and stable, which greatly reduces the damage of concrete bricks during transportation.

What steps are needed to operate QT4-20 automatic concrete block making machine?
1.Pour the prepared sand, cement, stones, water and other materials into JQ500 mixer, stir for 2 minutes, and then open the discharge exit of the mixer to off load mixed concrete material onto conveyor machine .
2. Concrete materials are transported to the hopper of the QT4-20 block-making machine by a 6m-long conveyor machine.
3. The concrete hollow brick is formed under the strong vibration force and extrusion of the QT4-20 concrete block-making machine.
4. After the concrete hollow bricks are molded and remolded, they are automatically stacked by a Henry stacker machine , and then the concrete bricks are transported to the designated position for curing outside by forklift driven by workers.
yes, the HENRY QT4-20 concrete hollow block machine will produce colorful paving bricks by reset the hydraulic system and adding one set of hydraulic oil route, and setting the parameters into the PLC system. Meanwhile, we will provide the color material feeding equipment in order to feed colorful pigment onto paver top surface
In the beginning, QT4-20 was matched with two 3kw vibration motors, which was the standard vibration force and was strong enough. Later, some customers felt the vibration force was too small, especially for producing hollow and porous bricks with relatively small wall thickness. The vibration force was often not enough, so we increased the vibration motor to 5.5kw.
Yes, the concrete foundation is needed because QT4-20 has a lot of vibration. First, to avoid the position shifting when the machine vibrates, and second, to reduce the noise generated when vibrating, customers need to pour the concrete foundation to fix the machine, according to the foundation drawing provided by Henry.
