23. Reloading -
cleaning system.
• head pulley slippage • belt tensions need to be adjusted
• excessive reloading at
the tail section
• loading problems, velocity of the
material is too high, see Section
4.6.
24. Spillage. • excessive reloading at
the tail section
• loading problems, bi-directional
loaders require a special design -
contact Hi Roller engineering
• loading problems, control gate
not properly installed, see Sec-
tion 4.6.
• loading problems, flow of mate-
rial is not directed down the back-
plate of the loader - see Section
4.6.
• loading problems, flow of mate-
rial is not evenly flowing down the
loader backplate - see Section
4.6.
• loading problems, straight down
flow of material - see Section 4.6.
• plugging tail section • loading problems, many factors
will cause spillage - see Section
4.6.
25. Splice failures. • mechanical splice is
wearing out prema-
turely
• belt speed and pulley diameter
specifications must be followed -
contact Hi Roller engineering
• belt tensions are important to
normal splice life - check for
proper belt tensions
• splice protector / wiper cleats
must be installed to reduce wear
on the splice - see “Belt Squaring
& Cutting” on page 42
26. Splice protector /
wiper cleats.
• cleaning system not
working well
• splice protector / wiper cleats
must be installed on all convey-
ors with all types of splices
• splice protector / wiper cleats
must be installed to protect and
clear the return bottom pan
27. Start-up problems. • belt frozen down • moisture must be eliminated
• head pulley slippage • poor head pulley lagging - new
lagging needs to be installed
• belt tensions are too loose
