Eight Advantages Of Qunfeng QFT block Making Machine

1) Uses Germany Siemens PLC control system and Siemens Touch Screen.

A. Human-computer interface screen with easy operation;
B. Is able to set up, update and amend the production perimeters, to maximize the
production output;
C. Dynamic display of the system’s status, automatic trouble shooting and warning
D. Has advanced logical safety lock function, avoiding mechanical accidents caused by
operational mistakes;
E. Is able to troubleshoot the machinery via remote control.

2) Uses proportional electrical and hydraulic control relief valves, which automatically adjust the oil flow and pressure as per specific working requirements, to buffer the hydraulic
cylinder when working; uses integrated high-pressure and soft oil pipes, with easy installation;

3) Optimun structure of vibrating shafts, which assures vibration distributed uniformly in the range of vibrating table, thereby improves the uniformity and stability of blocks, produces better quality of product than before when using the same ratio of raw material, and effectively reduces the noise.

4) Use special design of fixing table and knock type vibration, improves the speed of making product and the accuracy of the size of product.

5) Uses multi-shaft rotating and compulsory feeding, which greatly improves the density and intensity of the blocks, and reduces the feeding time as well;

6) Heavy-duty machine frame, which uses high-intensity steel and advanced heat treatment, is wear resistant.

7) Mould frame is made with inlaid structure, and mould are processed via the procedures of carburizing, nitriding and quenching which guarantee the strength of mould core and mould surface could be HRC52-HRC62.

8)Use the fully automatic heat treatment system,the lifespan of mould is more than 100,000 times.

Introduction on QFTⅡ 5-15 block production plant

1.Cement silo(45tons): It is used to store cement or fly ash ect. powder materials, including dust remover, level indicator, flange and broken arch. There are storage capacity 45t,100t,200t and 300t for choice.

2. Screw Conveyor: It is used to conveys cement/ fly ash from cement silo to cement scale and then to mixer.

3. Cement Scale:It is used to weigh cement or fly ash.

4.Batching machine for main materials ( sand, stone ect.)-Model PL80

5. JS500 twin-shaft concrete mixer

6.QFT5-15 Block & paver Machine

7. Color/face making machine The lifting rack is controlled by oil cylinder and links to pigment hopper with rubber spring, which could reduce the vibration and save surplus pigment.

9. Automatic pallet provider

10. Mould

11. PVC pallet
