Theory and Design of Dilute Phase Pneumatic Conveying SystemsDetergent Powder Production Powder Raw Materials Conveying

This article describes the theory and calculation method for de signing dilute phase pneumatic conveying systems It is based Therefore for these materials use a solids velocity 20 less than the gas velocity V g ie V p = 08V g For fine powders solids velocity is closer to the gas velocity For these materials use a slip factor of 09 instead of 08 This value generally ranges from The traditional method for lifting solid raw materials is using elevator but in this method there are such problems as large horizontal/vertical logistics large number of workers and labor intensity poor workshop operating environment raw materials temporarily stored in the high floors which is under large civil load If conveying pneumatically by dense phase above problems can be

VAC U MAX What is Vacuum Conveying Mixing and blending in the granular and powder food

Vacuum Conveying is the process of moving bulk dry materials such as powders from place to place within a factory using suction The material is transferred in a network of tubing from the pick up point or source to the customers processThe final mixed product either remains a liquid or becomes a semi solid like dough paste or cream Mixed products are further processed by methods outside the scope of granular and powder handling Mixed products are further processed by methods outside the scope of granular and powder handling

Low velocity slug flow pneumatic conveying of bulk solidsMaterials Transfer spiralmfg

As compared to dilute phase dense phase conveying is a preferred method of conveying due to its low power consumption low erosive wear and low attrition of particlsolids for well over 100 years Common applications include loading and unloading of trucks rail cars and barges transferring materials to and from storage silos and transferring of materials to production machinery within manufacturing plants In fact pneumatic conveying of bulk materials is used more widely in industry today than any other conveying method Transporting bulk materials
