Abstract
A tubular belt conveyor is supported by a plurality of support frames, some of which comprise a fixed roller and a pressing roller which is biased by compression springs to get close and away with respect to the fixed roller. Between the two rollers, narrow space is formed through which the forward belt is elliptically deformed so that the conveyed materials may be compressed. Particularly, with a steep slope, the materials thus solidified by the rollers can be easily carried by the tubular belt conveyor without slipping down.
