FIELD: mechanical engineering; metallurgy.
SUBSTANCE: invention relates to transporting systems operating with aeration of handled material and it can be used in metallurgy in transportation of alumina and fluorine salts. Proposed system consists of adjacent sections. Sections are coupled in tandem by connecting members and are separated by aircraft partition into two spaces: blow and material ones. According to invention, blow space accommodates pressure transmitter and air blower of device to deliver air into blow space of each adjacent section. Pressure transmitter is connected with input of control unit, and output of control unit is connected with device delivering air into each adjacent section. Air blowers are separated from wall of blow space by reed valves preventing reverse flow of air. Air blower consists of at least two pneumatically isolated fans arranged in casing and connected with control unit for series or parallel switching on.
EFFECT: provision of automatic rise of air pressure at increase of layer of transported material, increased capacity at transportation.
