This system combines image capturing and processing technology (ball scrap and ball charge) with an on-line digital platform for real-time estimates of the mass balance of balls in SAG mills (or Digital Twin).
The solution consists of an artificial vision system based on three embedded image processing systems.
Comprised of LIDAR depth cameras plus a 4k visible spectrum camera used to capture physical characteristics relevant for controlling both the ball mill feed inlet and ball scrap discharge at the SAG mill discharge.
Images are sent through a Wireless/lan link to a local processor for image processing and subsequent display on a DCS and/or Web platform.
The mass balance model is fed by information generated in the ball loading and scrap modules to calculate mass balance using the following formula: cumulative mass (Jb) = feed mass – discharge mass – spent ball mass.
