Usage of QT12-15 Fully automatic concrete block production line :
QT12-15 block making machine is latest developed equipment product, which is a special-purpose equipment for making building block making machine. The material of this machine can be flyash, slag, gangue or the others industrial waste, river sand, gravel, cement etc. Makes different sizes of hollow blocks, porous blocks, curbstone, pavement blocks, grass blocks, slope-protecting blocks, ring-tree blocks etc. If add color machine, it can make layering blocks.

Structure of QT12-15 :
QT12-15B type block machine adopts gantry frame type structure,made by super super steel,strong and shock resistant,very reliable.The design adopts the driving type material storage mode with independent foundation,to send the material when it is needed at once.Net wave swing type of material feeding device,with good feeding effect.Cartridge type welding mold,adopts qualified manganese steel by carburizing and quenching.no transformation and no damage after using 100000times.It can make the simple production line with PL1200 batching machine,JS500or JS750 mixer,8m conveyor belt and stacker.
Features of QT12-15 Machine :
This equipment is mechanical hydraulic PLC controlled synthesis technique equipment. Its characteristic is high efficient, easy-operated and easy-maintained. Block molding mainly by hydraulic, machinery as sideline, vibrate and press to finish molding blocks. The compressive strength of all blocks more than 15 MPa, compactness is high, impermeability and freeze resistance is better, and excellent capacity of sound insulation, heat insulation, insulation.external dimensions are precise.
