Self Tensioning Crusher Drive 500kW

Self-tensioning motor bases improve power transmission and belt life significantly*. This motor base relies on the Neidhart rubber spring that is pre-tensioned to store enormous amounts of energy which is gradually released as the belts lengthen after becoming worn out. A range of these self-tensioning motor bases was designed by our team and built by OST-Africa. *Courtesy of OST_Africa. Contact …

Crusher Drive

This crusher drive was the brain child of Philip Maree of OST-Africa that developed this size belt drive with self-tensioning functionality. The belt life has improved by three to five times relative to the rigid mounted motors. The design and engineering was performed by our team of engineers, inclusive of the FEA.

Floatation cell ready for commissioning

This flotation cell was designed for Bateman and was installed in a platinum mine in South Africa. This design has a unique concept that makes the install and removal of the agitator very quick without compromising the cell efficiency.

Apron feeders – Ore dump conveyors feeders

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 …
