<p>The device enables the user of the machinery, once the corresponding blast has taken place, automatically to distinguish the mineral content from the deads in order that the user can separate out the two components for subsequent processing, thereby avoiding dilution of the useful mineral or material in the deads. To that end, the device is constituted by an antenna (4), provided with the corresponding protective casing thereof, installed in the vicinity of the scoop (3) of the excavator, which antenna (4), via the corresponding wiring (5), is connected to a computer (6) fitted within the excavator (1), with the corresponding control display or screen (7) thereof, there being a supplemental plurality of RFID tags or radiobeacons (8) to be identified, whereby the zones where the various materials are located can be marked out by means of insertion of said tags or radiobeacons in holes or bores (10).</p> |
