The main processes of the compound vertical mixer are batching, metering and feeding. According to the weighing requirements, the time for each material Feeder to discharge to the metering tank is controlled to control the amount of material entering the metering silo. Then, according to the material ratio requirements, the time for each material feeder to discharge to the metering tank is controlled to control the weight entering the metering tank. In this way, a weighing process is completed. Until the specified number of weighing times required for each ingredient is completed.

The weighing mixer mainly completes the process control of batching measurement and feeding. The PLC manually sets and adjusts parameters such as the number of weighing times, counterweight, ratio, and impact difference on the CRT according to the user login level preset by the operator. At the same time, the actual value and the actual value of each batching, as well as the next target value calculated by the PLC, are displayed on the CRT. In addition to the number of times weighed, the number of times to be weighed, the ratio, etc., the system also requires equipment control requirements such as batching interlock, downward interlock, and upward interlock.

Features of the weighing control system

It adopts Mitsubishi, Omron or Siemens PLC as the core, which is small in size, high in precision and good in stability.

2. It can simultaneously control multiple scales, various materials or control the output (depending on the process).

3. The batching time is intelligently controlled, with no waiting between each batching scale, which shortens the batching cycle, increases the batching speed and output.

4. The latest WINXP system platform runs faster and more stably. It features real-time dynamic production screens that display the production process. The operation is intuitive, clear, and has an automatic recovery function.

5. Powerful reporting function, capable of recording and storing a large amount of various data and creating and printing tables. It automatically compiles and prints ingredient reports after each production is completed, providing information such as date, time, report number, and actual consumption of each material. Report extraction is carried out through manual query on a PC. At the end of production, the reports are stored inside the computer and can be read an unlimited number of times, ensuring the accuracy and completeness of the production reports.

6. The operation is simple. This system has three production modes: manual, semi-automatic and fully automatic.

Unique advantages of the automatic mixing system

The PLC has a strong data processing capacity, a fast and stable sampling rate, and the batching process can fully meet the batching requirements of the process.

2. The process can be set according to the user.

3. Good reliability: The system has two control schemes (touch screen and industrial computer schemes). When one of them malfunctions, the other immediately switches to operation without affecting production, effectively preventing production loss of control in case of production failures.

4. Real-time graphic display of the production process and text display of the production process facilitate the operation of operators.

5. The text file displays production reports, formula reports, etc. (with multiple print contents for users to choose from). The powerful alarm prompt function can minimize the scrap rate to the lowest extent.

6. The discharging speed is controlled by a frequency converter to ensure that all materials are discharged within an equal period of time, guaranteeing the uniformity of the batching.
