Systems of pneumatic transportation of cement and other fine materials with the minimum energy consumption

Transportation of fine construction materials during the manufacturing of concrete mixes iscarried out by systems of pneumatic transportation. The expense and pressure of air in thesystems are overstated during their design to avoid the blockage of pipelines. As a result, theenergy consumption of the equipment increases. At the same time, the equipment wear isaccelerated and the systems are operated on the unstable modes. Therefore, the operationalreliability of such equipment decreases and the process of cleaning of the exhaust air becomescomplicated. The solution of the problem of ecologically safety transportation of fineconstruction materials with the minimum energy consumption is given in the article. Theauthors developed a new type of energy saving systems of pneumatic transportation. It allowsreducing overstated reserves of the air expense and pressure during the design of the systems.Keywords: pneumatic transportation, fine materials. dust removal equipment, pape line
