The centralized feeding system is a production equipment used in industry for automatically and precisely proportioning and processing different powder or liquid materials in a certain proportion. It is usually composed of Weighing modules, weighing instruments, PLC systems and upper computers, etc., and includes various equipment such as raw material storage bodies, conveying bodies, weighing and batching bodies, dust removal bodies, and material mixtures. The batching method can be reasonably selected based on the characteristics of the industry, the requirements of the production process, and the specific properties of the materials, such as "incremental" or "subtractive" weighing methods. It has multiple working modes including single-bucket single-material, single-bucket multi-material, and multi-bucket multi-material.

The feeding system is a flexible and variable production control system software professionally developed by integrating industrial control technology and Internet of Things technology. It integrates all control points of the production process into a single control software, allowing customers to control the entire factory's production process only from the central control room. It has truly achieved a highly integrated, automated and unmanned efficient workshop. Central control data acquisition and control system: Comprehensive observation, centralized management. With PLC/DCS as the core control, the computer system is responsible for formula calculation, personnel management, data collection, query and printing, etc. The central control computer monitors and controls the on-site production situation, reflecting the operation status of each production unit in real time.

The process flow of the automated Batching system

The material enters the batching tank from the silo, and then is sent into the mixing tank from the reaction vessel. The weight is measured by the weighing module, and the speed of the frequency converter is adjusted according to the actual required flow rate to achieve normal feeding.

After being measured by the plate flowmeter, it enters the feeding box of the screw pneumatic conveying pump and is pushed forward through the feeding mechanism.

3: It enters the mixing chamber and is vaporized by the air at the fan outlet and then sent into the conveying pipeline.

During the above process, the frequency converter plays a role in quantitative flow stabilization. The flowmeter can not only accurately measure the flow rate but also detect whether the pulverized coal in the system is short of materials. The screw conveyor pump not only locks the air but also conveys the materials.

In terms of the Weighing system, advanced batching control type weighing instruments can be adopted. They can conveniently use communication methods such as ProFibus, MOD-BUS, and Ethernet to complete high-speed communication with the PLC system. They feature strong real-time performance, good reliability, and flexible configuration.

The demands of various users for weighing and batching.

Performance features of the batching equipment

The system is reliable, highly applicable, has high weighing accuracy, high automation accuracy, stable quality and is easy to manage.

The electronic weighing display design ensures high measurement accuracy and is easy to calibrate and maintain

Data processing: The batching system can automatically perform calculation and processing on the collected signals, thereby automatically controlling the normal operation of the equipment.

The communication function enables bidirectional data communication between the industrial control computer, PLC and instruments.

The monitoring function detects and monitors parameters such as the instantaneous flow rate, daily accumulation, monthly accumulation, and annual accumulation during the batching process.

The screen shows that the operating status of relevant control parameters during the batching process can be displayed through a computer monitor or weighing instrument.

Professional material handling capabilities, combined with the characteristics of users' raw material measurement, utilize various types of Feeders and inlet and outlet valves. The friendly human-machine interface can be connected to various types of controllers to perform quantitative measurement or batching process control. Multiple control mode options are available, and control can be carried out through forms such as PLC, human-machine interface, single-chip microcomputer, and industrial control computer.
