Weighing mixer is the ideal equipment for continuous batching and measuring of bulk materials, which has the advantages of simple structure, accurate weighing, stable use, convenient operation and small maintenance, etc. It is widely used in metallurgy, electric power, coal, mining, harbor, chemical industry, building materials, highway and other industries. It can be used for measuring and feeding materials and can be combined with multiple machines for automatic batching, used for continuous conveying of various powdery and granular materials for dynamic measurement, providing accurate measurement data for production, control and management of special industrial sites.

The whole automatic weighing and mixing machine is composed of industrial control machine, PLC, industrial weighing instrument, frequency converter, vibration motor, mixer, sensor, conveyor belt and other parts. The upper computer provides human-computer interaction interface, completes the control information input, data management, data display, storage, statistics and reports, etc. The upper computer adopts IPC810 industrial computer, and its main work is as follows: the host computer firstly reads a certain number of formula according to the operator's instruction, and then sends out the instruction to PLC to start the dosage according to the proportion of dosage in the formula and the sequence, so that PLC can start the specific frequency converter. Then, according to the proportion and sequence of the ingredients in the formula, it sends a command to PLC to start batching, which enables PLC to start a specific inverter. In the process of batching, the host computer of industrial control reads the status words of PLC in real time by polling, on one hand, to understand the operation status of PLC and PLC subordinate equipments; on the other hand, it reads the weighing data of the weighing instrument installed on the batching machine in real time, and according to the batching strategy, the host computer sends out the instruction of stopping batching to the PLC when the weighing is close to the set value of the recipe. When all the materials on a formula are finished, the whole dosage process is suspended, waiting for the operator's instruction. During the operation of the Batching system, PLC communicates with the host computer in real time, so as to ensure the consistency between the data displayed on the interface and the actual data on the site, the operation commands and setting parameters issued by the operator on the host computer can be sent to PLC in real time, receive the commands sent by the host computer, and control the vibration motor's starting, stopping and speeding up or slowing down through the frequency converter; write the operation status of the frequency converter into the memory data area in real time for the Read by the industrial control machine: Prepare its own various states in the form of status words for the industrial control machine to read in real time.

Dosing system is a kind of dosing equipment used in industry, control system production on the automation, usually by the computer (microcomputer) with automatic dosing algorithm software as its automatic dosing control system.

(1) The load cell uses high-precision weighing module. The weighing module is easy to install and maintain, which provides a reliable guarantee for the long-term stability of the system.

(2) The weighing instrument adopts T800 weighing instrument, and the weighing controller is characterized by high precision, high reliability and strong anti-interference ability.
