Solution Provided | Replacement design of Feed Chute
Discipline | Mechanical, Structural Engineering
A client engaged Carnac - Project Delivery Services (Carnac) to provide detailed engineering design to replace existing discharge chutes that were at the end of their life.
The project encompassed the following:
Conveyor skirting;
Fines Discharge Chute;
Dribble Chute; and
Grizzly Screen Exciter Access Platform.
The Carnac team provided professional design solutions in accordance with the client's process, operations and maintenance requirements.
The Carnac team recommended the following:
Angle the chute walls to 70°;
Extend the rear chute wall to ~180mm from the top of the belt;
Relieve the side wall to ~310mm from the top of the belt at the head end;
Remove wear billets along the head end 1/3rd of chute;
Install Keech skirts inboard of any sealing skirts; and
Install sealing skirts at 122mm edge distance in accordance with CEMA guidelines.
DEM Modelling was used to refine the chute design and optimise conveyor loading. The real-world results correlated strongly with the conceptual modelling. The client was provided with a lower maintenance chute that also reduced downstream skirt wear.
