1. The development of concrete mixing plant equipment has more than 10 years history in China, whose development process is introduction - digestion - part of domestic - all domestic - improvement.  It is common thing for the general concrete mixing plant to continuously produce 10000 cubic meters of concrete. And its key components such as hosts, screw machine, main control performance and pneumatic element have been quite stable. For instance,  the mixing blade uses the high chromium and high manganese alloy wear resistant material, and the  shaft bearing and sealing uses the unique and multiple sealing or airtight, which  greatly improve the reliability of the host.
2. The degree of automation control is higher. Since 2002, many concrete companies began to use two party hosts multiple parallel way, which improve the production capacity and reduce the waiting time of concrete transport vehicle. The control system is relatively advanced and stable, the degree of automation is generally high, which all can full automatically and long time continuous production. The operation platform and computer monitoring in the control room can vividly reflect the entire production process and the situation of each site, such as the storage condition of concrete in cement silo, aggregate storage in the aggregate bin, the conveying of concrete and the concrete discharging conditions. In this case, once some part has problem, which can be found in the shortest time, and resolved timely.
3. The controlling of all mixing plants adopts the industrial computer, which can automatically control and manual operation, the operation is simple and convenient. The dynamic panel displays the running situations of all components. The control room is equipped with air conditioning, which can ensure the electrical components durable, stable and continuously reliable performance.  The control system basically adopts two ways, one is the double control forms, and namely the system is composed of two sets of high performance industrial computer, one as the master production system, the other one as a backup machine management and monitoring system as master production machine. And the main control machine system has manual and automatic function, data between the control machine and the management machine can be shared together. When the control machine has fault, the managing machine will begin to work, which furthest ensure the continuous normal operation of system. The other is composed of the industrial computer and batching control instrument, namely the data of batching control instrument is input to the industry computer, and the signal is output through the board or PLC programmable controller, so the continuously normal operation of the system can be insured. You can also set the surveillance cameras in the host discharging port, proportioning station and other key components.
