Transportation of fine construction materials during the manufacturing of concrete mixes is carried out by systems of pneumatic transportation. The expense and pressure of air in the systems are overstated during their design to avoid the blockage of pipelines. As a result, the energy consumption of the equipment increases. At the same time, the equipment wear is accelerated and the systems are operated on the unstable modes. Therefore, the operational reliability of such equipment decreases and the process of cleaning of the exhaust air becomes complicated. The solution of the problem of ecologically safety transportation of fine construction materials with the minimum energy consumption is given in the article. The authors developed a new type of energy saving systems of pneumatic transportation. It allows reducing overstated reserves of the air expense and pressure during the design of the systems.
