氣力輸送設備一般由受料器(如喉管、吸嘴、發送器等)、輸送管、風管、分離器(常用的有容積式和旋風式兩種)、鎖氣器(常用的有翻板式和回轉式兩種，既可作為喂料器，又可作為卸料器)、除塵器和風機(如離心式風機、羅茨鼓風機、水環真空泵、空壓機等)等設備和部件組成。受料器的作用是進人物料，造成合適的料氣比，使物料啟動、加速。分離器的作用是將物料與空氣分離，并對物料進行分選。鎖氣器的作用是均勻供料或卸料，同時阻止空氣漏人。

Pneumatic conveying equipment is generally composed of feeder (such as throat, suction nozzle, transmitter, etc.), conveying pipe, air pipe, separator (commonly used are volumetric and cyclone), air lock (commonly used are flap and rotary, which can be used as both feeder and discharger), dust collector and fan (such as centrifugal fan, roots blower, water ring vacuum pump, air compressor, etc.). The function of the material receiver is to feed materials to create an appropriate material gas ratio and start and accelerate the materials. The function of separator is to separate materials from air and sort materials. The function of air lock is to evenly supply or discharge materials and prevent air leakage at the same time.

風機的作用是為系統提供動力。真空吸送系統常用高壓離心風機或水環真空泵；而壓送系統則需用羅茨鼓風機或空壓機。

The function of the fan is to provide power for the system. High pressure centrifugal fan or water ring vacuum pump are commonly used in vacuum suction and delivery system; The pressure delivery system needs roots blower or air compressor.

氣力輸送設備具有防塵效果好；便于實現機械化、自動化，可減輕勞動強度，節省人力；

Pneumatic conveying equipment has good dust-proof effect; It is convenient to realize mechanization and automation, reduce labor intensity and save manpower;

在輸送過程中，可以同時進行多種工藝操作，如混合、粉碎、分選、干燥、冷卻；防止物料受潮、污染或混入雜物等優點，因而在鑄造、冶金、化工、建材、糧食加工等部門都得到應用。它的主要缺點是動力消耗較大；

In the conveying process, a variety of process operations can be carried out at the same time, such as mixing, crushing, sorting, drying and cooling; It has the advantages of preventing materials from moisture, pollution or mixing with sundries, so it has been applied in casting, metallurgy, chemical industry, building materials, grain processing and other departments. Its main disadvantage is large power consumption;

設備(主要是分離器人口)和管道(主要是彎頭)磨損較快，如果設計、施工或運轉不當，則容易造成物料沉積，以致堵塞，使輸送中斷；不宜輸送濕度大、黏性大或易破碎的物料等。

The equipment (mainly separator population) and pipeline (mainly elbow) wear quickly. If the design, construction or operation are improper, it is easy to cause material deposition, blockage and interruption of transportation; It is not suitable to transport materials with high humidity, high viscosity or easy to break.
