2015 Building Construction!!! China Famous Hollow Block Machine for Sale QT4-25

1.  Simple introduction for QT4-25 concrete block making machine 

A. QT4-25 machine is semi-automatic newly developed, it adopts entire table vibrating ,mould vibrating ,and head pressing and vibrating ,so the products are even in density and high in strength.

B. The unique power -driven dosing and feeding device and powerful material distributing mechanism ensures the good quallity of all kinds of block products and the higher productivity ,so it can reduce the labor intensity better.

C. Compared to traditional product, it can sve more than 20%  of electric power .

Raw material Crushed stone, sand, cement, dust and coal fly ash, cinder, slag, gangue, gravel, perlite, 

and other industrial wastes.

Great Markets

Concrete blocks, paving stones with or without face mix, garden and landscaping 

products, slabs, edgers, curbstones, grass blocks, slope blocks, interlocking blocks, etc.

2. Advantages for our QT4-25 concrete block making machine 

A. The steel is national standard No.45 steel, the best in our country.

B. The welding is the best welding technology, anti-wear, aseismatic, anti Moist.
C. The mould is high temperature carburizing heat treatment through 900 Degrees Celsius.
D. Guide column: four guide column, use overlong guide design, the surface is chrome-plated, have good anti-wear and high anti-distortion, long service life.
E. Multi-function: exchanged moulds can produce solid bricks, hollow blocks and porous block can make all kinds of blocks.
F. Under the vibration platform there are two Super motors to drive the vibration box to vibrate and the up mould also has one motors to vibrate, so the forming way is vibration, so the blocks are of higher strength and compactness of uniform.

3. Kinds of bricks can be produced by QT4-25
