4.6. LOADING CONSIDERATIONS
The loader must be placed on the conveyor trunking so it will load in the same
direction of belt travel. It is at the loading point that the conveyor belt receives
major abrasion and almost all of its impact. The ideal condition is to have the
material pass from spout to belt at the same speed and direction of travel as the
belt, with a minimum amount of impact and centered on the belt.
Note:
Off-center loading is harmful to the belt, idlers, and shafting. An off-center load
will cause belt alignment problems.
Please consider:
• control gate orientation
• control flows from all spouts
• side loading problems
• high velocity and turbulent flows
• straight down flow problems
• poor loading leading to belt tracking problems
• belt speed vs. proper loading
• level/even loading problems
Y-spouts can cause side loading problems where the belt gets pushed sideways,
and leads to tracking problems. Improper loading will then reduce the capacity of
the belt.
Figure 4.4 illustrates typical side loading problems created by a Y-spout.
