Incline Drag Conveyors | Models | Design Features and Construction | Specifications

The incline series of Schlagel Powerflow conveyors is a continuation in our line of “En-Masse” conveyors introduced in 1970. This series is used when the normal 10 degree maximum incline of a standard series conveyor is not adequate to meet your needs.

Our incline conveyors allow a great deal more latitude in the design and layout of a bulk material handling system by enabling you to “bend” a conveyor up and over an obstacle.

You should keep in mind that while an incline style conveyor can offer a great deal of flexibility in your layout, it is better to try using our standard series of conveyors when possible. Our standard style gives you better efficiency at a lower cost and with less maintenance.

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.
