The powder pneumatic conveying system can adopt pneumatic conveying and mechanical conveying methods, which are often used in conjunction in the system. Pneumatic conveying can be positive pressure conveying or vacuum negative pressure conveying, and positive pressure conveying can be dense phase conveying or dilute phase conveying.

粉體氣力輸送設備廠(chǎng)家告訴我們：一般的組成設備都包括“倉泵、料倉、空氣壓縮機（或者是羅茨風(fēng)機、真空泵等）、管道、各種自動(dòng)閥門(mén)、旋轉卸料閥、螺旋輸送機（或提升機）、傳感器、破拱裝置、伴氣管道、氣吹裝置、自動(dòng)控制系統等。”

The manufacturer of powder pneumatic conveying equipment tells us that the general components of the equipment include "silo pumps, silos, air compressors (or Roots fans, vacuum pumps, etc.), pipelines, various automatic valves, rotary discharge valves, screw conveyors (or elevators), sensors, arch breaking devices, gas tracing pipelines, air blowing devices, automatic control systems, etc

粉體氣力輸送可以進(jìn)行長(cháng)距離的集中或分散輸送，高壓或低壓容器的供料輸送，并基本能做到定量輸送，便于生產(chǎn)管理。輸送時(shí)不受氣候和管路周?chē)鷹l件的影響，并可以避免輸送物受潮、污損、混入異物，沒(méi)有粉塵飛揚，便于保護產(chǎn)品質(zhì)量和衛生，工作環(huán)境好。

Powder pneumatic conveying can be carried out for long-distance centralized or dispersed conveying, as well as feeding and conveying in high-pressure or low-pressure containers, and can basically achieve quantitative conveying, which is convenient for production management. When conveying, it is not affected by the climate and surrounding conditions of the pipeline, and can avoid moisture, dirt, and foreign objects from being mixed in. There is no dust flying, which is easy to protect product quality and hygiene, and the working environment is good.

適應范圍大，粉末狀、粒狀、顆粒不大的塊狀、片狀物料，如水泥、面粉、谷物和樹(shù)脂切片等都可采用粉體氣力輸送。粉體氣力輸送可以滿(mǎn)足某些物料在輸送過(guò)程中的特殊要求，如氮氣、二氧化碳保護等。

It has a wide range of applications, and powder, granular, and small block and sheet materials, such as cement, flour, grains, and resin chips, can all be transported by powder pneumatic conveying. Powder pneumatic conveying can meet the special requirements of certain materials during the conveying process, such as nitrogen and carbon dioxide protection.

不過(guò)使用粉體氣力輸送設備也是有一定的缺點(diǎn)的，比如應用程序受到限制。粉體氣力輸送系統只能用于運輸，與其它固體物料輸送設備相比，粉體氣力輸送系統功率損耗比較大。

However, using powder pneumatic conveying equipment also has certain drawbacks, such as application limitations. The powder pneumatic conveying system can only be used for transportation, and compared to other solid material conveying equipment, the power loss of the powder pneumatic conveying system is relatively large.
