  • Recycle material feeding system

QT4-15 Block Making Machine is one leading supplier in China. Guaranteeing stable and timely supply, credible quality and sincere service, our products sell well in both domestic and overseas markets. and to fulfill strictly ISO 9001:2008 and CE standard. Lontto Block Making Machine has been sell in South Africa and Malaysia,  Russian, Saudi Arabia, Chile, Peru, Uganda and so on.


  • This Construction Concrete Hollow Block Making Machine has high-efficiency and super-strong vibration system, to realize vertically synchronous vibration, frequency conversion, and braking.
  • The machine frame is made of super-strength steel and by special welding technology, the imported elements are applied widely.
  • The whole process uses a PLC control and dialogue system of human-machine interface, easy to analyze the chance signal.
  • The special loading and supply unit, the multi-line whipping forks are fixed at inside of material feed box. The whipping forks work and feed the material to mold box forcedly during the material feed box moves to up of mold box.
  • Recycle material feeding system: Economize in material for different or same density products.
  • Reliability design of The machine frame is made of super-strength steel and by special welding technology, the imported elements are applied widely, so that the stability and reliability of the machine in the long-term running are insured.
  • Hydraulic parts and seals parts on hydraulic pressure system are from Japan or Taiwan, which protects pressure discharging or leakage.
  • Multi-use; Strong performance; The many kinds of products with different form and size can be made when using the difference mold, such as wall block, honeycomb type block, roadblock and slope block
