Forced mixerGood mixing quality, strong overload capacity, discharge without segregation, high production efficiency, can adapt to a variety of performanceConcrete mixingCommercial concrete mixing equipment is generally used forced mixer。But its structure is more complex, the use cost is higher。The forced mixer is divided into several forms: double horizontal shaft, single horizontal shaft, single vertical shaft and planetary type，Double horizontal shaft mixer has good mixing performance，High production efficiency，well-adapted，Prominent structural features，Good reliability，Very suitable for commercial concrete production;Single horizontal shaft mixer and single vertical shaft mixer due to their structural characteristics and adaptability，The application in commercial concrete mixing equipment has become less and less: the application of planetary mixers is not common，Most common in imported equipment。

Electronic control system of commercial concrete mixing equipment

国内Concrete mixing plantThe electronic control system has a variety of forms, mainly in the following three control methods。

(1) Distributed microcomputer control: This form of control is widely used in the early design of mixing stations。The core of the control system is a programmable controller, and the upper level computer is only used for printing management reports, and the function and role of the computer are not obvious。With the wide application of commercial concrete, mixingConcrete mixing plantThe functional requirements are becoming more and more complex, and the application of this form of control is very difficult。

(2) Centralized microcomputer control: This form of control will computer control and management functions are concentrated in a computer, the task is relatively heavy, and the statistics of the report data in the production process can not be synchronized, can not statistical data at any time, measurement by human factors interference too much。For example, the preparation of measurement control programs, the accuracy of signal amplifiers and A/D boards will affect the measurement accuracy。

Centralized dual microcomputer control: This form solves the interference of human factors in measurement。A dedicated batching control instrument is used, and the production control and management functions are placed in two computers without interfering with each other, and the production control and report statistics are carried out simultaneously, and the management computer can also be used as a production backup machine, providing a network interface with the upper-level computer。
