At Minera Centinela the ore that feeds the primary crusher is of the exotic type with a high content of fines and clays, which results in a ROM (run of mine) feed grain size curve of 80% under 1 inch. In addition to the above, when the mineral has a humidity of more than 5.5%, the crusher is jammed as a result of the adherence to the walls of the feed hopper and compaction of the material, generating suspended load. In addition to the above, the material entering the crusher chamber adheres to the walls causing restrictions in the discharge flow. Both conditions generate operational discontinuity, reduced plant performance, risky conditions for the people in charge of cleaning, and damage to the facilities.
