Condition Monitoring for Challenging Mining Pit Conveyor Applications
As an arterial system in most mining operations, bulk conveyors must be properly monitored and maintained to avoid costly repairs, time-consuming and unsafe manual inspections, and unplanned downtime that could bring your entire process to a halt. Emerson can help minimize downtime with condition-based monitoring systems and wireless transmitters to continuously monitor critical components and provide safe and cost-effective data collection for continued conveyor operation.
Some components, such as the take-up pulley, are difficult to monitor because they travel as much as 100 feet. Wireless monitoring is ideal for this application, while online systems with tachometer inputs maybe be required for the variable speed operations on other parts of the conveyor.
