Partition plate position control device, partition plate position control method, and table specific gravity beneficiation system provided with partition plate position control device

摘要

PROBLEM TO BE SOLVED: To enable a table specific gravity concentrator to automatically control positions of a partition plate with high precision in accordance with gold line positions, and to cope with a sudden change in gold line position by accurately estimating gold line positions from an image obtained by imaging a gold line region on an oscillation table in a table specific gravity concentration system.SOLUTION: From an image obtained by imaging with an imager 110 a gold line region on a panel 2 installed on an oscillation table 3 that disperses ore grains fed with water streams under a specific gravity, the center vector of a gold line is obtained by the least square method in an image analyzer 150 to estimate a gold line width from a standard deviation, where in accordance with estimated results of gold line positions, position control information is generated on the basis of position control parameters to control the position of a partition plate 4 with a controller 140, so that a processor 160 performs abnormal detection processing for saving the image of the gold line region where the estimated result has been obtained, and for changing the position control parameters when detecting that the estimated result of the gold line position has changed by exceeding a preset predetermine value.SELECTED DRAWING: Figure 1
