A material management system and method manages and tracks the progress of excavated material transferred through an excavation site by a conveyer system operating in cooperation with an in-pit crusher and conveyer (IPCC). The material management system distinguishes the material dispensed into the IPCC into identified material batches. To track the identified material batches, the material management system records data regarding the conveyer speed and the conveyer distance associated with the IPCC, as well as possible other data regarding the identified material batches. The material management system processes this to track the indentified material batches along the conveyer route.

Provided are a raw material discharge device, a method of processing an electronic and electrical device component scrap, and a raw material discharging method of an electronic and electrical device component scrap, which are capable of efficiently discharging the raw material having various shapes, specific gravities and shapes in each fixed amount. A raw material discharge device including: a storage unit 1 which stores a raw material and comprising a discharge port 11 at one end; a discharge unit 2 arranged at a bottom surface 15 of the storage unit 1, which conveys the raw material toward the discharge port 11 and discharges the raw material to an outside of the storage unit 1; an adjustment unit 3 including a plurality of struts 31 extending from above to below the discharge unit 2 and adjusting an amount of the raw material to be discharged by holding a part of the raw material with the struts 31; wherein a ratio (d1/d2) of a distance (d1) between a strut 31 closest to a side surface 13, 14 of the storage unit 1 and the side surface 13, 14 of the storage unit 1 to a narrowest distance (d2) between the struts 31 in a center portion of the storage unit 1, and a ratio (H1/H2) of a height of the strut 31 closest to the side surface 13, 14 of the storage unit 1 from a floor to a minimum height (H2) of a strut 31 which is other than the strut 31 closest to the side surface of the storage unit 1 from the floor are respectively adjustable so as to prevent clogging of the raw material being discharged to the outside of the storage unit 1.
