Product Handling – Coaling Coke

Application

1-on-1 transfer with 1400 mm wide belts and a 13.5m vertical drop

Objective

• Eliminate dust emission, particle degradation, impact energy and noise level
• Improve housekeeping and safety by reducing material spillage
• Centralized loading

Challenge

The old chute system had been in place for many years and was a patchwork of steel that covered numerous points where \ material wore through the shell. Coaling cokes are highly abrasive and the maintenance on the old chute was excessive. Frequently, these repairs resulted in costly delays in ship unloading operations due to emergency patchwork that required stopping the line.
Additionally, there was a high volume of coke 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.

MCFT Solution

The engineers designed and fabricated a 1-on-1 chute that included removable hard rock liners to handle the abrasive wear of the coaling coke. This system has been in operation for several seasons with minimal maintenance required on the liners. The material flow path produces efficient material handling with little spillage of the cokes, along with minimal dust generation.

Result

The unscheduled stoppages due to emergency patchwork have ended and the facility is spending minimal time maintaining the chute and cleaning up spilled material. This provides for efficient and cost effective operation, and allows the facility to get unloaded without costly interruptions for chute repair.
