摘要：
A method for pneumatically conveying material through a conveyor conduit comprises automatically interposing into the conveying operation cleaning phases in which no material is introduced into the conduit, to remove material previously deposited in the conduit. Apparatus has a timing means which rhythmically interrupts the introduction of material, and the strength of the air flow in the cleaning phases can be greater than that of the air flow during the conveying phases.
