Weighing control system in is an organic whole, storage unit, dosage unit, control unit is the three inseparable basic units, is to ensure that the flow of material dosage of the necessary conditions. The basic unit of material and conveying links in the material changes will have an impact on the flow. Batching control not only rely on the improvement of the regulating device and control software optimization to continuously improve the quality of the regulation of the dosage, but also with the dosage process is inextricably linked, only from the point of view of the dosage engineering, in order to grasp the direction of the development of the dosage control to meet the modern industrial automation of large-scale production requirements.

Weighing mixer including raw material storage, transportation, weighing batching, dust removal, material mixing and other batching equipment, involving powder and granular solids bulk materials, liquids and other materials. Weighing and batching equipment can be based on industry characteristics, production process requirements, specific material characteristics, reasonable choice of "zero" or "reduction method" and other weighing methods, with a single hopper single material, single hopper multiple materials, multiple hoppers multiple materials and other modes of operation.

The weighing and batching machine is set up in the production site with a centralized control console, the dynamic weighing instrument is installed on the console, the load cell data line installed in the lower part of the support leg of the discharge system is connected with the dynamic measuring instrument, the real-time data is uploaded to the industrial control machine of the control center by the weighing instrument through the communication line, and the formulas and control commands are downloaded to the explosion-proof electronic weighing instrument and PLC controller through the communication line by the industrial control machine of the control center;

Siemens S series PLC programmable controllers and relays are installed inside the operation console, which are responsible for controlling the starting and stopping of the automatic valves and pumps;

The weighing and mixing machine is started under the control of PLC, and different signals (fast feeding, slow feeding, unloading, etc.) are outputted to PLC at different measuring stages for direct control of external equipment by PLC;

Installation of push-button switches, etc. on the operating table to realize manual control of the above mentioned parts;

There are emergency stop buttons at the field operation place and the centralized control console, and the two emergency stop buttons are connected in series, which are used for emergency power-off treatment in case of emergency;

The equipment is equipped with a stirring motor, controlled by a frequency converter.
