Gold wire region imaging device in table specific gravity mineralizer and control method thereof, and table specific gravity concentration system with gold wire area imaging device

摘要

PROBLEM TO BE SOLVED: To acquire stably and surely a clear image of a gold wire area on an oscillation table in a table gravity concentrator.SOLUTION: An oscillation timing of an oscillation table in a table gravity concentrator is detected, and operation of an imaging device installed over a board provided on the oscillation table is controlled based on its detection output, and a gold wire area on the board is imaged at a timing near a stop position where oscillation speed of the oscillation table becomes slowest.SELECTED DRAWING: Figure 1
