The tubular drag conveyor consists of a tube with a line with (plastic) disks set on it moving inside the tube. The disks are not tightly fitted in the tube; they move with a relatively high linear speed and set in motion the material and the air inside the transporter. This results in fluidization of the transported product ensuring its delicate transport in conditions similar to pneumatic transport. The advantage of the conveyor is a high efficiency of transport, no need to adjust dust removal and a small area required for conveyor installation.
