3. QT12-15 Block Making Machine

Our company is one of the leading manufacturers of QT 12-15 automatic concrete block making machines inChina. With more than 20 years’ production experience, we can make use of various raw materials for production, such as crushed stone, sand, cement, dust, coal fly ash, cinder, slag, gangue, gravel, perlite and other industrial wastes. As the moulds are changeable, this block making machine is able to produce various kinds of hollow blocks, solid bricks, interlocking bricks, pavers, curbstones, and so on.
QT 12-15 automatic concrete block making machine is extensively used in building, road paving, square, garden, landscaping, city construction, and so forth.


Features of Block Making Machine

1. Double oil cylinder drives crank arm connecting rod system is used on feeding system. Material feeding can be quicker, more sooth and steady.
2. Motor reducing gear is used on rotation device in the feeding box.
3. Four terminal input vibrators are used on the vibration table. Special design for vibration table stand to make vibrating force equally distributed, and all products height keep accordant and forming faster.
4. VFDs motors are used to control the vibration tale amplitude and frequency to fit for different moulds and products.
5. Air suspensions are used on the mould box .Adjustable damping can reduce working noise and prolong the machine service life.
6. PLC intelligent control and man-machine interface system can do random signal analysis, fault diagnosis and parameter setting during the whole process and insure the machine keeps best working effect.
7. It adopts fully hydraulic variable frequency vibration to realize accurate and adjustable vibrating speed. This automatic concrete block making machine also overcomes the defect that the motor will be damaged after long-term work and meets different production requirements of raw materials.

4. Cement Scale

The cement scale hangs on the mixer. It buildup by hanging shelf, pull sensor, electron-steelyard and valve. It is used to scale the weight of the cement. Used for cement laden in bulk, if you use cement in bag, you can add cement by manual, no need for cement scale.

5. Water scale

The water scale hangs on the mixer. It buildup by hanging shelf, pull sensor, water tank and water pump. It is used to scale the water
6. Belt conveyor (transport mixed material to block making machine)
7. Screw conveyor (Transport bulk cement from cement silo to mixer) 8.Face feeding device (Optional, to make color paver)

9. Stacker

10.Mould
