Screw dosage system technology application

Spiral weighing and batching system is the ideal equipment for continuous batching and measuring of bulk materials, with 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 single machine and can be combined with multiple machines for automatic batching, used for continuous conveying of a variety of powdery, granular materials for dynamic measurement for the production, control and management of special industrial sites to provide accurate measurement data.

The mixer ribbon agitator consists of a U-shaped horizontal trough and a specially manufactured ribbon agitator. The agitator consists of a set of internal and external helical agitators that provide powerful lateral and radial movement of the bulk material. The ribbon rotates at approximately 350 fpm, ensuring thorough mixing in a short cycle time. Another type of agitator is our paddle design, which provides gentler mixing and is better suited for friable materials. Either agitator design can typically accommodate as low as 25% of the agitator's maximum operating capacity. Vacuum allows for faster drying and solvent recovery at lower operating temperatures. The deaerated environment also promotes better interaction between discrete particles, resulting in enhanced homogeneity and faster integration of minor additives such as flavors, fragrances, colors and APIs.

Spiral weighing batching machine is developed with the high degree of automation of modern industrial production and the increasing complexity of process control, it is integrated with automatic control technology, computer technology and communication technology, has the advantages of advanced technology, complete functionality, flexible application, reliable operation, etc., and with the increase in the degree of intelligence of the measuring instrument, it makes the control of the batching system more flexible and more powerful. It is the more ideal control system for the production process of the enterprise.

Composition and working principle of batching system

The automatic batching system includes a set of industrial PC management system, a set of PLC electrical weighing control system, and N sets of single-loop closed-loop control circuits; each closed-loop control circuit consists of screw conveyor, automatic batching system (including weighing control display, load cell, etc.), frequency converter and field control box. And leave the communication interface with the upper computer.

The material is conveyed into the hopper scale of the dosage system. The weight signal is sent to the weighing instrument. Weighing instrument will load the weight signal after arithmetic and processing to arrive at the weight of the material, respectively, in the weighing indicator display.

The configuration of the instrument is a high-performance intelligent weighing instrument. The instrument and the frequency converter control the speed of the screw conveyor to form a closed-loop control. The built-in intelligent software regulator of the weighing instrument can set high, medium and low feeding levels to ensure the accuracy of the dosage. The output of three sets of signals is used to control the frequency converter, which in turn controls the feeding speed of the screw feeder, so as to achieve the purpose of accurate dosage. Intelligent weighing meter can set the feeding quantity manually or set the proportion through the two-way communication between computer and meter.

The ICC communicates with PLC through serial port. According to the actual process of dosage process, the ICC reflects the operation status of feeding, dosage, delivery and related equipment in the form of dynamic screen. When there is an over-limit fault during operation, there will be an alarm prompt in Chinese characters and an alarm (sound and light) will be activated to alarm, or shut down, or change the warehouse, and the analysis of the control status can be made based on the operation data, and the system's dynamic dosage process will be reflected in the bar graph with different colors. According to the operation data, the industrial control machine can give the proportion or feeding quantity, and truly reflect the dosage status. In addition, the ICC is equipped with a self-developed dosage system. The dosage system also has other functions, such as shift report, daily report, monthly report, annual report and so on. It provides convenient management.
