This apron feeder was installed in a Botswana diamond mine and was completely designed in-house by our team. Its purpose is to break the fall of rocks before they are conveyed to the crushers. The drive components were are selected from Caterpillar. The slats were designed and cast to allow smooth gliding around the curves and also to facilitate moderate sealing. The drive-end shaft featured a tapered shrink fit coupling with the gearbox. A pleasant characteristic of this design was how quiet it operated compared to conventional machines of the same kind.
