Abstract:
1. A method of vacuum-pneumatic transportation of bulk materials of high mass concentration comprising pneumatically transporting the bulk material through a transporting pipeline from an original zone with atmospheric pressure into a receiving zone, creating a vacuum in the receiving zone maintaining a stable concentration in mass in the transporting pipeline by fluidization materials wherein vacuum in the receiving zone is created by alternate actions of impulses from at least two vacuum receiver, wherein each of said at least two receivers is connected to a continuous vacuum source connected by pipes with quick-acting valves to the receiving zone in such a manner that while a vacuum impulse is acting from one of the receivers on the receiving zone, each of the said at least two receivers synchronously disconnects from continuous vacuum source during the time of the vacuum impulses and another of said at least two receivers is connecting to the continuous vacuum source.
