Shandong Juheng Environmental Protection Equipment Co., LtdFor many years, dedicated toPneumatic conveying system equipmentVarious types of pneumatic conveying tools are provided for various industries such as petroleum, cement, steel, coal yards, etc., including powder conveying, dense phase conveying, positive pressure conveying, and workshop dust removalCheng. Aluminum oxide is a high hardness compound with a melting point of 2054 ℃ and a boiling point of 2980 ℃. It is commonly used in the production of refractory materials and can ionize at high temperatures. In industrial production, alumina is mainly prepared from bauxite and boehmite, which have higher purityAl2O3 is mostly prepared by chemical methods. Aluminum oxide powder is a white solid that is insoluble in water, odorless, and tasteless. It can be used as an analytical reagent, dehydration of organic solvents, adsorbent, organic reaction catalyst, abrasive, polishing agent, and smelting aluminumRaw materials, refractory materials, etc. It can also be used to add hardness to materials such as dental cement, porcelain, paint fillers, mordants, metal aluminum, etc. It can also be used for thermal conductivity, polishing, electroplating, catalysts, etc.

The pneumatic conveying system for alumina powder, also known as the alumina powder airflow conveying system, mainly utilizes the energy of the airflow to transport granular materials along the airflow direction in a closed conveying pipeline. It has the advantages of horizontal conveying, easy operation, simple structure, and the ability to tilt at multiple anglesConveying, during the conveying process, physical or chemical operations such as material cooling, dust removal, drying, and airflow classification can also be carried out simultaneously. Compared with conventional mechanical conveying, the pneumatic conveying system for Juheng alumina powder has the advantages of high conveying speed, long conveying distance, and the ability to transport in multiple placesLoading and unloading at one location, capable of loading and unloading at multiple locations. During the conveying process of the alumina powder pneumatic conveying system, the material is conveyed in a sealed pipeline with a conveying distance of over 500 meters, good surrounding environment, and can be transported over long distances.

According to the density of alumina powder particles in the conveying pipeline and gas pressure, there are alumina powder dilute phase pneumatic conveying system, alumina powder dense phase pneumatic conveying system, alumina powder dense phase pneumatic conveying system, and alumina powder positive pressure pneumatic conveying systemAluminum oxide powder negative pressure suction pneumatic conveying system, etc., including:

1. Aluminum oxide powder dilute phase pneumatic conveying system: In general, during the conveying process of aluminum oxide powder dilute phase pneumatic conveying system, the solid content is 1-10kg/m3, and the conveying distance is generally within 300m. The material in this system is suspended in a vertical pipe and evenly distributedThe horizontal tube is characterized by a flying state, high airflow velocity, and low conveying pressure.

2. Aluminum oxide powder dense phase pneumatic conveying system: In general, the solid content of the aluminum oxide powder dense phase pneumatic conveying system is 10-30kg/m3 or the solid gas ratio is greater than 25, and the conveying distance can reach 500m or more, with a pulsating group flow in the flow stateHigh air pressure conveying, suitable for long-distance transportation, low conveying speed. Due to the high conveying pressure, the material conveying pipeline of the Juheng alumina powder pneumatic conveying system adopts wear-resistant materials and intermittent inflatable tank dense phase conveying, which can blow granular materials into the conveyingTransported through pipelines.

3. Negative pressure suction pneumatic conveying system for alumina powder: It can be used for centralized conveying from one place to multiple places, and is easier to transport materials with higher moisture content than pressure conveying. The material pipe can be equipped with one or more branch pipes, and can not only sequentially transport materials from multiple feeding pointsThe characteristics of conveying to the unloader and conveying materials under negative pressure include easy evaporation of moisture, low equipment investment, and high conveying speed. During the transportation of alumina powder material, the pressure inside the pipeline is lower than atmospheric pressure, and the material is sucked in by itself, but it needs to be discharged under negative pressure, usually negative pressureThe pneumatic conveying distance is relatively short.

4. Aluminum oxide powder positive pressure pneumatic conveying system: It can be used for dispersing and conveying aluminum oxide powder materials from one place to multiple places. Compared with positive pressure pneumatic conveying, the material is easier to discharge from the discharge port, and compared with suction conveying, the concentration and conveying distance can be greatly increasedThe suction type pneumatic conveying system has the characteristics of simple structure and low fan wear.

5. Aluminum oxide powder mixed pneumatic conveying system: It can extract materials from multiple locations, transport materials to multiple locations simultaneously, and the conveying distance is relatively long; The gas containing the material passes through the fan, accelerating the wear and tear of the fan; The entire device is quite complex.

The pneumatic conveying system for Juheng alumina powder requires few operators, high operating efficiency, and can avoid material moisture pollution or mixing with other debris. It can be operated remotely by concentrating and delivering points to one location or dispersing points from one location. According to the material of alumina powderConsideration of conveying characteristics: comprehensively consider the material characteristics such as brittleness, wear resistance, shape, density, etc. of alumina powder particles; Considering the technical and economic performance of the device, such as alumina powder material pressure delivery, dilute phase gas delivery, dense phase dynamic pressure gas delivery, etc; According to ShengConsider the technological characteristics of the production process; Consider selecting a suitable and cost-effective pneumatic conveying system based on various types of combinationsShandong Juheng Environmental Protection Equipment Co., Ltd. has been committed to pneumatic conveying system equipment, powder conveying, dense phase conveying, positive pressure conveying, workshop dust removal and other issues for many industries such as petroleum, cement, steel, coal yards, etcPneumatic conveying workerCheng。
