PARTITION PLATE POSITION CONTROL DEVICE AND PARTITION PLATE POSITION CONTROL METHOD IN TABLE GRAVITY BENEFICIATION MACHINE, AND TABLE GRAVITY BENEFICIATION SYSTEM COMPRISING PARTITION PLATE POSITION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a partition plate control device that automatically controls the position of a partition plate with high precision in adjustment to a gold line position by accurately estimating the gold line position from an image obtained by imaging the gold line position on an oscillation table in a table gravity beneficiation system.SOLUTION: In a table gravity beneficiation system 100, with respect to an image obtained by making an imaging device 110 image a gold line region on a plate provided on an oscillation table 3 that diffuses ore grains supplied with water streams, an image analyzer 150 obtains a gold line center vector by a method of least square to estimate a gold line width from a standard deviation, and a control device 140 controls the drive of a partition plate drive device 10 in accordance with estimation results, thereby positioning the partition plate 4 on the gold line position estimated by the image analyzer.SELECTED DRAWING: Figure 1
