The working principle of concrete mixing plant

Concrete mixing station mainly by the mixing host, material weighing system, material handling system, material storage systems and control systems and other five major systems and other ancillary facilities. As the building aggregate measurement and station aggregate metering compared to the reduction of the four intermediate links, and is the vertical material measurement, saving the measurement time, thus greatly improving the production efficiency, the same model, the mixing plant production efficiency ratio Mixing station production efficiency increased by one third.

The working principle of concrete mixing plant

The concrete mixing plant is divided into four parts: gravel feed, powder (cement, fly ash, expansion agent, etc.) feed, water and admixture feed, transmission mixing and storage. The working process shown in Figure 1 , The mixer control system after power-on, into the human-machine dialogue interface, the system initialization processing, including the recipe number, concrete grade, slump, the amount of production, etc. According to the weighing of the silo, Detection, output material empty or full signal, prompting the operator to determine whether to start the mixing control program. Start sand, stone belt motor feed to the metering bucket; open the fly ash, cement tank butterfly valve, start the screw motor transport fly ash , The cement to the metering bucket; open the water tank and the additive tank of the control valve so that water and admixture into the metering bucket. Metering meet the set requirements after the opening of the bucket door, the ingredients into the activated mixer mixing, to set Time to open the mixer door, the concrete into the material into the mixing car.

  1. Each cylinder, control valve and motor are operated according to the requirements of the concrete mixing process. The control of each cylinder, control valve and motor must be accurate, stable and reliable.

  2. control system with automatic, manual two modes of operation, and the relationship between each other is independent and each other constraints.

  3. system has good anti-interference ability and perfect alarm self-protection function.

  4.  through the computer communication, you can display the system working status, fault alarm.
