Impact of material being loaded on the belt is often the cause
of severe cuts and gouges.
The degree of impact can be
lessened to some extent by providing a cushion in the form
of rubber covered disc type or semi-pneumatic idlers, which
also tend to prevent material from crowding under the skirt
boards at the instant of impact (Fig. 26).
The use of a “Grizzly,” a slightly fanned row of bars, at the
bottom of the transfer chute reduces wear on the belt. It
distributes the impact of large lumps by allowing the fines to
fall onto the belt first to act as a cushion.
The fan shape of the
“Grizzly” in the direction of travel prevents jamming of the
lumps (Fig. 27).
A “V-slot” cut in the bottom of the chute is another very
satisfactory method of allowing fines to fall on the belt
before the lumps and thereby reducing belt wear at this
point (Fig. 28).
