High Angle Conveying, the Vital (missing) Link to IPCC Systems – 2017

Installations and recent studies have demonstrated the technical and economical advantages of high angle conveying for optimization of any IPCC system, yet that industry continues to struggle with the use of conventional solutions to achieve the high angle function.

Summary and Conclusions

The two objectives of this writing were to provide the developmental timeline of the modern sandwich belt high angle conveyors and to demonstrate their proven suitability to handle the bulk elevating (or lowering) duties of any IPCC system. The latter was the more important objective and it is supported by the former. So, are sandwich belt high angle conveyors suitable for IPCC applications? This writing has demonstrated a resounding yes when the design is pursuant to the Dos Santos development. The many installations presented demonstrate that:

  • they can handle very high conveying rates,
  • they are suitable for continuous 24/7 operation,
  • high tonnage requirements are handled by wide belts that can easily handle large, primary crushed material, and
  • conscientious design, by DSI, will ensure long life with minimal maintenance required.
     

The system is proven commercially now for more than thirty years with success in a significant IPCC system more than twenty five years ago.

End users of IPCC equipment have been disappointed by the large IPCC manufacturers who have failed to embrace the gift of sandwich belt high angle conveying - a compact, versatile, vital link to any IPCC system. Some are taking matters into their own hands and with our help they are developing their own IPCC systems with sandwich belt high angle conveyors as the vital link.
