(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 notice;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)使用电子和成比例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）采用多轴旋转和强制进料，这大大提高了块的密度和强度，并减少了馈电时间;

(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-HRC61.

（8）模具的寿命不低于100万倍。Further more information & pictures about this production line, please contact with our company.Qunfeng Machinery.
