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

Powder screening, mixing and conveyingis a process of transporting bulk materials from one or more sources to one or more destinations by using airflow as a transport medium.，Air flow is generated by compressed air or other gases, and a certain air flow speed and pressure are formed in the pipeline. These air currents suspend the material particles in it, or transport the materials along the pipeline in a group state. In this process, the material particles are in a liquid state under the action of airflow, so as to realize the continuous and stable transportation of materials.。

1、Brief introduction of Powder screening, mixing and conveying

Powder screening, mixing and conveyingis a kind of material conveying equipment which uses the energy of airflow to convey granular or powdery materials along the airflow direction in a closed pipeline.。

2、Structural advantages of Powder screening, mixing and conveying

The Powder screening, mixing and conveying has the following structure

1. dust pelletizing system

Dust removal system is very important for the environmental protection performance of Powder screening, mixing and conveying system. It is responsible for handling the dust and waste gas generated in the transportation process to ensure that the discharge meets the requirements of environmental protection. Dust removal system usually includes dust collector, fan and discharge pipeline. According to different material characteristics and environmental protection requirements, different dust removal equipment and technical schemes can be selected.

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. control system

The control system is the "brain" of the Powder screening, mixing and 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.

4. 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.

5. 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、Powder screening, mixing and conveying use

The purpose of Powder screening, mixing and conveying is introduced as follows:

1. Environmental protection and cleaner production

The Powder screening, mixing and conveying process is carried out in a closed pipeline, which effectively prevents dust from flying and leaking, thus reducing environmental pollution and harm to employees' health. This is especially important for industries that need to maintain high cleanliness or dust-free environment.

2. Reduce pollution

The Powder screening, mixing and conveying system carries out material transportation in a fully enclosed state, which effectively reduces the environmental pollution caused by dust flying and material leakage.

3. cut down on energy consumption

Although the power consumption of the Powder screening, mixing and conveying is relatively large, the energy consumption can be reduced by optimizing the system design and selecting efficient equipment, so as to achieve the goal of energy saving and consumption reduction.

4. Adapt to complex environment

The Powder screening, mixing and conveying system can adapt to various complex environments and layout requirements. Whether in high temperature, high humidity, corrosive or flammable and explosive environment, the normal operation of the system can be ensured by selecting suitable materials and taking corresponding safety measures. In addition, the Powder screening, mixing and conveying pipes can be flexibly arranged according to the actual situation of the production site, which makes the configuration of factory equipment more reasonable.

5. Long distance transportation

The Powder screening, mixing and conveying system can realize long-distance material transportation and meet the demand of long-distance material transfer. This is especially important for some large factories or cross-regional material transportation.
