Chute Design through DEM

Due to bad transfer chute design the reliability of belt conveyors not always is reflected in an increase in reliability for the overall plant. Improving the design of transfer stations requires observation and experience but increasingly it requires an improvement in the application of available technologies such as DEM.

The present requirement for higher annual throughput capacity in the iron ore industry generally demands higher design capacity and speeds for belt conveyors. Conveyor belt technology has advance to meet the demand. However the reliability of the belt conveyor at high capacity is not reflected in an increase in reliability for the overall plant.

In part this is due to the transfer chute, an increase in unscheduled downtime such as blockages and schedule downtime such as increase in maintenance requirements.

Improving the design of transfer stations requires observation and experience but increasingly it requires an improvement in the application of available technologies such as flowability technology and discrete element methodology. These technologies require test work on representative samples to determine the input data. Reliable data is required to predict outcomes such as the likely hood of blockage and predictable flow trajectory.

This article illustrates present knowledge and future potential for transfer chute design.
