As ore moves through the mill, it is important to maintain an optimal size with the resulting rock fragments. Too big and the rocks can be difficult to transport and can damage equipment. Too small and energy is wasted from over-blasting. Motion Metrics’ latest innovation, BeltMetrics, is a fragmentation analysis and empty belt detection solution that continuously analyzes rock fragment size on a mine site conveyer belt. The system uses camera monitoring on the conveyer belt to feed information through an artificial intelligence system to accurately scale and measure each rock. BeltMetrics has the ability to measure fragments smaller than one centimetre in diameter and to run 24/7, and alerts mine staff when rock size is trending away from ideal measurements. The company said BeltMetrics is an improvement on sieve analysis, the traditional method for monitoring rock size, which is time-consuming and requires rock samples to be taken off the belt.
