Transfer Detail

The transfer handles 10,000 tph of pellets from a Great Lakes ship unloading operation that feeds to a stacking conveyor.


Time had taken its toll on the old chute, which was worn out from years of service, and the maintenance time for repairing and patching was excessive. Additionally, taconite pellets were spilling out of the chute, resulting in extra clean-up costs and lost material. Additionally, there was a high volume of pellets spilled on the ground. This caused a severe safety hazard since the pellets are spheres and pose a fall hazard to personnel walking on them. Because of this, the facility had excessive housekeeping costs to ensure the area around the chute was kept in a suitable condition.

Tasman Warajay Solution

Designed with Tasman Warajay Technologyâ„¢, a new chute was supplied that allows for the full CEMA flow of material throughout the full luffing and slewing ranges of motion. The lining system for the new chute is designed to provide extended wear life with the hard rock lining system from Tasman Warajay.


This facility is spending very minimal time maintaining the transfer chute and cleaning up spilled material around it. This provides for efficient and cost effective operations and allows the facility to get ships unloaded without costly interruptions for chute repair.
