Endless belt conveyor for particulate material - has upper run travelling over idle wheels and lower, return run travelling over curved garland rollers

摘要

The gravel or sand conveyor comprises an upper transport run and a return run below it forming an endless belt. It has a portion (4) forming a passage in which the top run (2) travels over one or more idler wheels (10) rotating on transverse shafts (11). The wheels extend through an oblong opening (6) in the bottom of the passage. The lower return run(3) travels over one or more free supports (14), e.g. a set of garland rollers, keeping its edges higher than its centre, thus retaining any material which drops through the opening.
