Hainuo concrete mixing plants adopt modularization structure design, so it is easy to install and disassembly. The plants work in high efficiency. The concrete produced is good quality. The control system adopts PLC logic program automatic control management and every process is under computer precise control. This system make the plant more security and easy to operate. The whole close mixing body, aggregate conveying system and dust cleaning system highly reduce the noises and air pollution. 1.Mixing system: There are Germany BHS, TEKA, Italy SICOMA, HAINUO (less than 2m3) twin shaft mixers for choices. It can mix the hard-ready, malleable and different compounding rate concrete. Advanced mixer structure, high wearable mixing arms and lining title, special mixing angle assure it excellent mixing function and long-life. 2.Operation control system: The whole mixing system adopts stable PLC center and computer management. There are three kind work style, automatic, semi-automatic, and manual. The industry computer controls the whole production completely. It can save many compounding rating data and show every system? operation clearly by monitor. The advanced printing system can print all kinds of report list and data. The function of the whole system is perfect and anti-jamming. The key parts are imported originally, which improve the stability and security of the system. 3.Balance system: the balance adopts direct electronics, high precision sensors. The feeding system of aggregate is equipped with four storage that balance the aggregate simultaneously. In this way, that largely shortens the compounding cycle and improves the balance precision. As for the additive, because of the important influence of to concrete homogeneousness. The farinose additive Transferred by high precision screw conveyer. The liquid additive is mixed by advanced circular mixer, which avoid lowering the quality of concrete result from precipitate. So the whole balance system is low absolute error and high precision. 4.Feeding system: The system including storage and conveying device. The position of aggregate storage and main mixer can be designed according to client? requirement. The aggregate is conveyed by horizontal belt and declined belt. As for cement storage, there are 60 ton, 100t, 200t, 300t,500t for client? choices. The cement, coal dust, farinose additive are conveyed by declined angle screw conveyer.
