Description

Technical field [0001] The invention relates to an online ore particle size detection device, in particular to an ore particle size online detection device based on graph image algorithm analysis technology. Background technique [0002] The inside of the ore is composed of useful minerals and gangues. Beneficiation is to crush and screen the ore through a crusher to fully dissociate the useful minerals and gangues. The method of beneficiation is limited by the particle size of the ore. The gangue is not dissociated and cannot be sorted, and the fine ore particles are still difficult to control with the current beneficiation method. [0003] At the same time, crushing and screening have the following effects on production technical indicators: the crushing process will be accompanied by materials that have been crushed or not fully dissociated. Because of insufficient dissociation, the grade and recovery rate of the selected concentrate are low. Too fine will cause more fine parti...
