Patent ID: 8284096

Claim:
A system to detect uncrushable metallic pieces hidden inside a mineral load directly inside a transport device to a primary crusher, the system comprising: a directionally adjustable radar that includes at least one device having electromagnetic wave emitter/receiver antennas used to scan a mineral load that is transported by the transport device; a portal through which the transport device passes, with a top section where at least one antenna device is located to face the mineral load of the transport device; a spectral generator/analyzer connected to the antenna devices that generates electromagnetic waves and analyzes the echoes of the electromagnetic waves that interact with the mineral load, distinguishing a characteristic echo produced by a metallic element hidden inside the mineral load; and a computational device that includes a digital signal processor connected to the spectral generator/analyzer to allow data to be stored in its temporal or frequency domain for further processing and to deliver information regarding the transport device check results to the user.
