Recently, a large gold-silver mine brought to our attention their concerns regarding site access and maintenance, highlighted during the two years of Covid travel restrictions. With estimated reserves of 6.4 million oz of gold, avoiding unscheduled downtime is an important priority.

CST supplied 5 belt weighers to the site in 2009, and have been providing service and support ever since.  
As a welcomed solution, during the February 2022 CST site visit we installed the latest MaVIS WIM3 with the latest firmware.  CST’s unique MaVIS WIM3 electronics component can be fitted to any brand of belt weigher, and enables a range of unique features.

The latest version of the system includes a unique easy access and functionality  called the Calibration Dashboard (more on this below). Further, the WIM3 Remote Care Service (RCS) provides remote weigher monitoring systems which enable expert technicians to view and address site problems without the need to travel, no matter where in the world the site may be.  This is a fast way to resolve maintenance issues and avoid costly unscheduled downtime disasters.

The WIM3 Calibration DashboardThe Calibration Dashboard (world patents in progress) is our built-in QA system that very effectively avoids calibration mistakes and incorrect parameters that may otherwise occur. All the important sub-systems which affect accuracy are monitored with respect to their ideal value, and subsequently traffic lighted to ensure all errors or faults are highlighted.

The example below shows a fault in the tachometer calibration.  The basis for the tachometer is that the radius of turning must be inside the belt thickness.  The Calibration Dashboard has saved many catastrophic problems on site due to the constant automatic monitoring of this aspect.

Each sub-system keeps a record of the last 10 values so you can see if something has gone wrong or if the unit has been calibrated correctly.

CST, with nearly 40 years of market leading innovation, are committed to being the best belt weigher company in the world by providing the most stable and most accurate products, calibration services and weighing equipment.  We are constantly researching and working closely with our customers to learn more about real day-to-day issues, and consequently provide valuable solutions for material transfer on conveyors.
