Nowadays, the powder industry is becoming increasingly popular, involving many industries such as building materials, pharmaceuticals, and machineryIt plays an important role in many industries, and the transportation of powders is also divided into various forms. The transportation mode can be divided into two forms: dry transportation and wet transportation, depending on the carrier being transported.

       Firstly, let's talk about the wet conveying method, which refers to the use of hydraulic or other liquid slurries to transport materials, that is, a form of conveying materials through slurries or hydraulic means, usually using pipelines to transport a mixture of granular materials and water. The dry transportation method is a form of powder transportation that maintains the dry state of the conveyed material. Dry transportation is also the most common form of powder transportation. In dry conveying, it is divided into three categories based on different transport carriers, namely mechanical transportation, container transportation, and pneumatic transportation. The first two methods use mechanical devices or transport containers respectively, while pneumatic conveying refers to the transportation method that uses air to move dry materials in pipelines. Most powder transportation chooses pneumatic conveying because of its advantages such as flexible layout, good hygiene conditions, high conveying efficiency, and the ability to effectively reduce labor intensity.

       So powder pneumatic conveying has these advantages: (1)pipelineNot occupying space on other devices,compact footprint；（2）pipelineplaceflexiblechangeableLess investment in equipmentCost savings; （3）Clean and low pollution，sealed systemAfter excellent design by the manufacturer's designerCan prevent environmental pollutionMake the entire system free of excessive dust; （4）By integrating the conveying process, there is no need to stop the original process equipment, which enables the entire process to be automated and upgraded, improving efficiencyTransportation efficiency.（5）Operators are not related to conveying capacity, personnel configuration is minimized, and management is convenient；（6）For materials with unstable chemical properties, inert gas transportation can be used.
