During the exploitation of minerals in open pit mines, the blasting operation is carried out to fragment and facilitate the loading and hauling to the crushing plant Occasionally, fragmentation is not complete and oversize ore are generated and exceed the maximum granulometry allowed by primary crushing.
In the Andina Division, Codelco oversize ore with a size greater than 1160 mm must be reduced by hydraulic rockbreakers before feeding the primary crusher which interfere with the continuity of the crushing process and causing production issues.
For this reason, a search for technological solutions is required to detect oversized ore on the shovels and/or in the mining trucks, prior to feeding to the primary crusher
