Theory of Operation
This series of conveyors differs from our standard conveyors in many ways. The trough area utilized for material conveying is only about 40 percent compared to approximately 85 percent in the standard series. This results in a larger trough housing for a particular capacity requirement.
The incline series conveyors cannot be flood or choke fed unless a by-pass inlet section of trough is used. If you are going to control feed the conveyor then your inlet must be placed far enough in front of the tail sprocket so that material is not fed directly into the sprocket area.
Figure 1 shows the control fed method by which the capacity is determined by a feeding device such as a bucket elevator, another conveyor or a process machine. The conveyor speed is adjusted so that at maximum capacity the material conveying chamber within the trough is never more than 95 percent full.
Figure 2 shows the flood fed method by which the capacity is determined entirely by the speed of the conveyor. The material conveying chamber is always nearly 100 percent full. It cannot be overfed because the bottom of the by-pass shroud does not allow excess product to enter the conveyor. This feature is very useful when used with a truck or rail dump hoppers, or when reclaiming material from storage bins. It is important to remember that when using a by-pass inlet that full capacity requires material to be fed around both sides of the by-pass shroud.
The horsepower requirements for an incline conveyor are greater than for a standard conveyor for a particular length and capacity. We strongly suggest that you always contact the factory for an actual horsepower requirement due to the many variables that need to be considered for these types of conveyors.
