Chute Technology said its new coal and ore handling technologies, which are designed to overcome production-limiting factors at mines and bulk handling terminals throughout Australia, are proving their worth in service for Ulan Coal in New South Wales.

Ulan ChuteTechA customised transfer chute for a section of the bypass system has eliminated spillage at Ulan Surface Operations, dramatically reducing downtime. “The new chute allows Ulan Surface Operations to operate with a full feed rate of 2,000 tonnes per hour without any stoppages or blockages, so they can maximise their productivity and profitability,” said Dennis Pomfret, managing director, Chute Technology.

By contrast, the legacy arrangements were a source of multiple hours of lost production. An engineering audit by Chute Technology determined that functionality of a known trouble spot, the bypass hopper and vibratory feeder, could be replaced with a simpler transfer chute with an in-built surge capacity. The modular, asymmetric chute was designed in such a way that it could all be lifted and installed in one go, to minimise installation downtime.

Chute Technology also designed and installed an adjustable surge control baffle device to control the height of material on the conveyor belt. The device acts like a trimmer on the end of the chute, where it trims the height of material during times of surge loading, to avoid belt overloading, side spillage, and keep material heights consistent.

With such a strong return on investment and the chute already operating as designed with no downtime, Chute Technology said the project is being seen as a template for the future.

Ulan Coal operations are 100% owned and managed by Glencore.
