Strategies for Managing Multiple Loading Points
When a conveyor belt is loaded at multiple points along its length, it's crucial to carefully position the skirtboard at these loading points. The skirtboard at subsequent loading points should be designed to allow previously loaded material to pass freely without being pushed off the belt by the skirtboard or chute steel of the next loading point. 
Since it's challenging to ensure that material is loaded evenly and centrally onto a conveyor with multiple loading points, some plowing and spillage of material are likely unavoidable. This fugitive material increases operating and cleanup costs and can lead to premature equipment failures. Therefore, incorporating continuous skirtboards is a recommended practice.
When loading points are close together, it's generally better to use a continuous skirtboard between these points and to use a deeper trough angle than usual, rather than using individual skirtboards at each loading point.
Another effective approach for situations with multiple load zones is the installation of an air-supported conveyor. Air-supported conveyors are particularly suited for multiple load zones because they require only a centered load, unlike traditional skirtboards or skirt seals.
