4、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. Air source device

The air source device is the power core of the Powder screening, mixing, and pneumatic conveying system, which provides the airflow power needed for transportation. Common air source equipment includes roots blower, compressor, centrifugal blower and water ring vacuum pump. These devices can generate stable airflow and provide sufficient power for the transportation of materials.

5. 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、Powder screening, mixing, and pneumatic conveying application

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

1. Reduce pollution

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

2. Process assistance

In some production processes, Powder screening, mixing, and pneumatic conveyings are not only used for conveying materials, but also as part of the process. For example, in the chemical and pharmaceutical industries, the Powder screening, mixing, and pneumatic conveying system can cooperate with other equipment to realize process operations such as mixing, grading, drying and cooling of materials, and improve production efficiency and product quality.

3. material handling

Powder screening, mixing, and pneumatic conveying system is widely used in conveying all kinds of powdery, granular and small block materials. These materials include, but are not limited to, cement, fly ash, grain, plastic particles, ore, pulverized coal, pharmaceutical powder, etc. Through the pipeline system, these materials can be efficiently and continuously transported from one place to another, greatly reducing the complexity and cost of manual handling and mechanical transportation.

4. Dust removal and purification

The Powder screening, mixing, and pneumatic conveying system is usually equipped with a dust collector to collect and treat the dust generated in the transportation process to keep the production environment clean and hygienic.

5. Adapt to complex environment

The Powder screening, mixing, and pneumatic 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 pneumatic conveying pipes can be flexibly arranged according to the actual situation of the production site, which makes the configuration of factory equipment more reasonable.

Powder screening, mixing, and pneumatic conveying

Powder screening, mixing, and pneumatic conveyingthe advantage is Materials are transported by closed pipelines.，No dust leakage, environmental protection and pollution-free, fully sealed and pollution-free transportation.、The conveying system is closed, which can prevent the materials from being affected with damp, soiled and mixed with other sundries in the conveying process, and ensure the conveying quality of the materials.、In the conveying process, various technological operations can be carried out at the same time.、The materials concentrated from several points can be sent to one place or sent to scattered points from one place.、Can realize the transportation of materials in a closed pipeline.，Can effectively prevent moisture and sundries from polluting materials, fully sealed and pollution-free transportation.，Mainly using the dynamic pressure and static pressure of air, the material particles are suspended in the airflow or transported in groups along the pipeline.，widely used in logistics, plastic, building material, cast, chemical plant and other fields。
