Powder conveying and batching system

Introduction to Powder Ingredient System

The powder batching system provided by our company is an equipment system that uses powder conveying, storage, and various measuring sensors to transport, mix, and feed one or more powder materials according to the quantity, ratio, and feeding. It is a commonly used integrated equipment in the production processes of fine chemical, chemical, paint, oil, medicine, feed, daily chemical, food, pharmaceutical and other industries. It is usually an automated batching equipment system composed of DCS control related equipment modules, such as unpacking stations, conveying pipelines, storage compartments, measuring compartments, etc. For example, powder feeding control for reaction vessels, packaging ratio of finished powder products such as talc powder, resin, and feed.

Previously, production enterprises often used mechanical weighing methods or flow meters (volumetric specific gravity) for batching, which not only could not guarantee process control and had low measurement accuracy, but were also greatly affected by environment and temperature. The powder batching system includes various equipment such as raw material storage, conveying, weighing batching, dust removal, and material mixing, which make up for the deficiencies in these measurement methods, ensure the process, and reduce losses.

Performance characteristics of powder batching system

1. Stable system, strong applicability, high degree of automation, easy management, and stable product quality;

2. High precision electronic, high measurement accuracy, on-site display, easy calibration and maintenance;

3. Each unit is equipped with professional and mature material processing equipment, including automatic unpacking stations (large and small packages), various conveying pipelines (spiral, pipe chain, pneumatic conveying, bucket lifting, etc.), storage compartments (ingredient level sensors), measuring compartments (high-precision electronic scales), spiral feeders, various inlet and outlet valves (pneumatic/electric butterfly valves, gate valves, one-way valves), automatic dust removal and exhaust devices (sensor control), etc;

4. DCS system control, perfect human-machine interface, connecting and commanding various types of controllers, executing quantitative measurement or batching process control;

5. According to customer functional requirements, multiple control modes can be selected, which can be controlled by PLC, human-machine interface, microcontroller, industrial computer and other forms. It can be fully automatic or combined with semi-automatic and semi-automatic to reduce equipment investment costs;

6. System integration can be diversified and integrated, and can be perfectly matched with surrounding equipment, such as raw material equipment, factory overall dust removal system, etc., which can be planned and designed according to demand;

7. Reasonable on-site layout design, which can be configured according to user production volume and workshop environment

Functions of powder batching system

1. Control: Replace manual management and automatically control the normal operation of equipment according to the corresponding set values;

2. Display: The display can show the ingredient process, control parameters, and operating status, as well as real-time ingredient curves and tables; Both the industrial control room and the site can be equipped with displays, and touch screens can be installed for display and management on site;

3. Data: The ingredient system automatically calculates, processes, and outputs the collected signals;

4. Communication: Bidirectional data and information exchange occurs between the industrial computer, PLC, and instrument, ensuring smooth human-machine dialogue;

5. Monitoring: Detect and monitor parameters such as flow rate and cumulative quantity during the ingredient preparation process, and retrieve them at any time;

6. Printing: Data reports can be printed at any time for easy saving and querying;

7. Alarm: The upper computer alarms various parameters exceeding limits or equipment status abnormalities through visual and audio-visual signals.

Classification of Powder Ingredient Systems

1、 Semi automatic batching system - single control batching system

The single control batching system is characterized by its simplicity, practicality, and flexibility.

The form is: one control instrument controls one quantitative feeding and measuring equipment. If there are N types of materials, use N control instruments to control N quantitative feeding and measuring equipment. Each route is manually set, controlled and operated to achieve automatic batching. Widely used in industries such as feed, metallurgy, building materials, and chemical engineering.

2、 Automated batching system - constant value batching mixing system

The fixed value batching system is a system device that uses a DCS system to control the entire conveying batching system, completely replacing on-site manual operation, and combining PLC, sensors, and related hardware equipment. The human-machine interface has fast response speed, reliable performance, and precise and stable control data.

IIIAutomatic weighing and batching system

The weighing and batching system composed of weighing modules is mainly used for weighing and batching various materials (solid, liquid, gas) in industries such as chemical, feed, and electrical materials. The system can adopt various working modes such as single bucket single material, single bucket multi material, etc. Ingredient system: divided into standard and advanced types. Intuitive display of process management, capable of printing and outputting reports on product consumption, storage, and ingredients. The automatic weighing and batching system can be roughly divided into sequential batching and continuous batching.

Sequential batching is commonly used, and various materials are added to the measuring bin in the set formula order. Only one material is allowed to be added to the measuring bin at any time. The user inputs a fixed formula, and the weighing system detects and controls the data of the measuring warehouse, feeding pipelines, inlet and outlet valves, etc. to add materials according to the formula. Only one set of weighing devices is used, with a simple structure and high accuracy.

Continuous batching can be used for some non intermittent batching or process requirements that require continuous operation. Each material is weighed separately and added to the production equipment according to the set flow rate. Multiple weighing and measuring warehouses form a continuous batching system. Users can input various formulas for continuous feeding or proportional feeding, with high accuracy and fast speed.

4、 DCS system

The powder conveying and batching system has been upgraded to DCS controlled fully intelligent operation, avoiding data loss and errors. The entire system is stable and reliable, and reduces the workload of on-site operators, making it environmentally friendly, hygienic, safe, and stable.
