Steep angle conveying, whether by means of pocket, sandwich or bucket type conveyors, should be considered in the context of alternative layouts or equipment configurations.
Examples of different layouts are shown here which indicate why steep angle conveyors have benefits over alternative bulk handling conveyor technologies.
a. Angle of inclination
The diagram indicates the need to elevate material from the ground level to the top of a silo. Two fundamental options exist namely, utilise either a troughed / pipe - type belt conveyor or employ a steep angle conveyor.
The steep angle conveyor layout is compact, utilises the silo for support and is usually the more cost effective solution. It is however necessary to consider the application in context to the overall project. If for example, the inclined troughed conveyor depicted above was only the head-end of a long overland conveyor, then employing a steep angle conveyor as shown would probably be less attractive.
The 'systems approach' to conveyor selection is therefore extremely important, as one other factors included in this section.
