What are conveyor impact beds?
In high volume heavy impact areas of a conveyor, conventional trough rollers located at the hopper location (i.e. where the material is first loaded on the conveyor) will not tend to support the belt effectively. Meaning that, given enough impact and material weight, the belt may sag between the rollers. This will increase the opportunity of the belt slipping below the skirting rubber and allowing material to spill out the sides.
To reduce the chance of material spillage and damage occurring to the trough rollers, impact bars are used. These bars help absorb and disperse the impact of the incoming material.
Impact bars are often made from a rubber/polyethylene combination, and are generally designed to be easily replaceable.
The below image shows how the impact bars support the belt between rollers. Hence reducing any chance of material spillage.
