What is a Powder screening, mixing, and pneumatic conveying? Introduction to the advantages, characteristics, and principles of the pneumatic conveying

Powder screening, mixing, and pneumatic conveyingis a kind of material conveying equipment which combines jet technology and fluidization technology.，at the start of the operation,The material and air flow form a gas-solid two-phase flow to realize continuous and stable material transportation.，is a popular Powder screening, mixing, and pneumatic conveying，It has a wide range of uses, and is often used inEnvironmental protection and cleaner production,Dust removal and essence,material handling,cut down on energy consumption,Process assistance and so on，widely used in heat-engine plant, build a ship, metallurgy, pharmaceutical factory, chemical industry and other fields。The following is to introduce the Powder screening, mixing, and pneumatic conveying:

1、Brief introduction of Powder screening, mixing, and pneumatic conveying

Powder screening, mixing, and pneumatic conveyingis a process of transporting bulk materials from one or more sources to one or more destinations by using airflow as a transport medium.。

2、Structural advantages of Powder screening, mixing, and pneumatic conveying

The Powder screening, mixing, and pneumatic conveying has the following structure

1. Bunker system

The silo temporarily stores and releases materials. The silo is usually designed as a pyramid or conical structure to facilitate the storage and unloading of materials. The design of silo needs to consider the different problems of materials in the process of storage and unloading and the flow form of materials.

2. Conveying pipeline system

The conveying pipeline is a channel for conveying materials after mixing with airflow. It is made of wear-resistant and corrosion-resistant materials to ensure that the materials will not be polluted or damaged during transportation. The diameter, shape and length of the pipeline will be designed according to the characteristics and delivery capacity of the transported materials. In addition, the pipeline system may also include some auxiliary fittings, such as valves, elbows, expansion joints, etc., for regulating air flow and pipeline connection.

3. Feeding device

The feeding device is responsible for feeding materials evenly and stably into the conveying pipeline. It is usually installed at the beginning of the system, and uses the negative pressure or positive pressure formed by the air source device to mix materials with air in a certain proportion and send them into the pipeline. Common feeding devices include rotary valves, screw conveyors, rotary feeders, screw pumps, silo pumps and Venturi nozzles. The selection of feeding device should be considered comprehensively according to the characteristics of materials and transportation requirements.

4. control system

The control system is the "brain" of the Powder screening, mixing, and pneumatic conveying system, which is responsible for monitoring and controlling the whole system. Through the control equipment such as programmable controller, the parameters such as airflow speed, feed rate and system pressure can be accurately adjusted and controlled to ensure the stable operation of the system and meet the production requirements.

5. Bunker system

The silo temporarily stores and releases materials. The silo is usually designed as a pyramid or conical structure to facilitate the storage and unloading of materials. The design of silo needs to consider the different problems of materials in the process of storage and unloading and the flow form of materials.

3、Working principle of Powder screening, mixing, and pneumatic conveying

Powder screening, mixing, and pneumatic conveyingin the course of work,Compressed air or other gases are passed through the air supply device to generate airflow, forming a certain airflow speed and pressure. Subsequently, the material is sent into the conveying pipeline through the feeding device, and under the action of the airflow, the material particles are suspended in the airflow or flow along the pipeline in groups. This gas-solid two-phase flow state enables materials to be transported to the target position along the pipeline. In the process of transportation, gas-solid separator (such as dust collector) is used to separate materials from air to ensure the quality of transported materials.，the product looks atmospheric.，it can be used in chemical plant, machine building, medicine, plastic, grain processing and other industries，It is mostly used in Multi-point transportation, Heating, cooling and drying, Mixing and classification, Reduce pollution, Process assistance, Long distance transportation and so on，can be customized according to user's needs.。

4、Functional advantages of Powder screening, mixing, and pneumatic conveying

Powder screening, mixing, and pneumatic conveyings have the following advantages.

1. High degree of automation

The Powder screening, mixing, and pneumatic conveying system can realize automatic control and remote monitoring, which improves the automation level and production efficiency of the production process.

2. Multi-point to multi-point transportation

The Powder screening, mixing, and pneumatic conveying system can realize multi-point to multi-point transportation, meet the needs of different production lines and improve the production flexibility.

3. High conveying quality

In the process of conveying, the Powder screening, mixing, and pneumatic conveying system can prevent the materials from being wetted, stained or mixed with other sundries, thus ensuring the quality of the conveyed materials.

4. High degree of automation

The Powder screening, mixing, and pneumatic conveying system is easy to realize automatic control and can be operated through the central console, which reduces the labor cost and improves the production efficiency and management convenience.

5. Material quality protection

In the process of conveying, the Powder screening, mixing, and pneumatic conveying can prevent the materials from getting wet, soiled or mixed with other impurities, thus ensuring the quality of the conveyed materials. This is especially important for some industries that require high material quality.
