Design of White Carbon Black in Pneumatic Conveying System
? ? ?White carbon black in closed transportationPneumatic conveying systemBefore designing the white carbon black pneumatic conveying system, the design conditions must be clearly defined. Although pneumatic conveying systems have some unique advantages, they must be used under certain conditions to fully exploit their strengths. Therefore, before designing the pneumatic conveying system, it is necessary to conduct research to meet the conditions of pneumatic conveying. The physical properties of conveyed materials that need to be understood in pneumatic conveying design include particle size, particle size distribution, shape, density, bulk density, suspension velocity, moisture content, moisture absorption, friction angle, flowability, fragmentation, corrosiveness, electrostatic effect, abrasion resistance, toxicity, radioactivity, etc.
? ? ?Generally, the average particle size of the material is used as the particle size of the material. But some materials contain fine powder, which is prone to moisture absorption and adhesion, causing pipeline blockage and silo arching;
? ? ? The flowability of materials is usually represented by static friction angle and internal friction angle. The smaller the static friction angle, the smaller the internal friction angle, and the better the material flowability.
? ? ? Liquidity is closely related to the moisture content of materials. Even if the moisture content of the same material is different, its flowability can vary greatly. Some materials are also very sensitive, such as urea, ammonium sulfate, saltpeter, potassium chloride, etc. When these materials come into contact with the atmosphere, they will deliquescence and dissolve due to moisture absorption, which not only affects the flow of the materials, but also forms large blocks that cannot be transported for a long time after a period of time. Therefore, when redesigning the pneumatic conveying system for moisture absorbing and agglomerated materials, the worst-case atmospheric conditions should be considered to prevent accidents in the pneumatic conveying system, and to handle particle breakage and allowable particle breakage to determine the conveying method.
