粉体气力输送系统可以采用气力输送和机械式输送方式，这两种方式在系统中经常会配套使用,气力输送可以是正压输送，也可以真空负压输送，正压输送可采用密相输送也可以采用稀相输送。

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 use dense phase conveying or dilute phase conveying.

粉体气力输送设备厂家告诉我们：一般的组成设备都包括“仓泵、料仓、空气压缩机（或者是罗茨风机、真空泵等）、管道、各种自动阀门、旋转卸料阀、螺旋输送机（或提升机）、传感器、破拱装置、伴气管道、气吹装置、自动控制系统等。”

The manufacturer of powder pneumatic conveying equipment tells us that the general composition equipment includes "bin pump, material bin, air compressor (or Roots blower, vacuum pump, etc.), pipeline, various automatic valves, rotary discharge valve, screw conveyor (or elevator), sensor, arch breaking device, gas tracing pipeline, air blowing device, automatic control system, etc."

那么粉体气力输送都有哪些优缺点？下面就带大家一起来进行了解一下！

So what are the advantages and disadvantages of powder pneumatic conveying? Now let's take everyone to learn more!

粉体气力输送可以进行长距离的集中或分散输送，高压或低压容器的供料输送，并基本能做到定量输送，便于生产管理。输送时不受气候和管路周围条件的影响，并可以避免输送物受潮、污损、混入异物，没有粉尘飞扬，便于保护产品质量和卫生，工作环境好。

Powder pneumatic conveying can be used 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 mixed in the conveyed material. There is no dust flying, which is easy to protect product quality and hygiene, and the working environment is good.

适应范围大，粉末状、粒状、颗粒不大的块状、片状物料，如水泥、面粉、谷物和树脂切片等都可采用粉体气力输送。粉体气力输送可以满足某些物料在输送过程中的特殊要求，如氮气、二氧化碳保护等。

Suitable for a wide range of applications, 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.

不过使用粉体气力输送设备也是有一定的缺点的，比如应用程序受到限制。粉体气力输送系统只能用于运输，与其它固体物料输送设备相比，粉体气力输送系统功率损耗比较大。

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 with other solid material conveying equipment, the power loss of the powder pneumatic conveying system is relatively large.
