• To change the direction of the conveyor route it
is necessary to utilise a tube bend or a redirection
station. A sprocket or a rim wheel (fig. 3a,b) can
be used for redirecting the chain in small radii.
A major fault is the usage of a sprocket wheel
while transporting bulk solids with a high filling
level. The abrasion between chain, bulk solid and
sprocket wheel is so enormous, that the conveyor
will be damaged after a short period of time (fig.
3c).
