Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ore sorting equipment, and in particular to an ore sorting equipment. BACKGROUND

[0002] Ore sorting is a core link of efficient utilization of mineral resources, and its effect directly affects the beneficiation cost, resource recovery rate and tailings treatment pressure. The conventional beneficiation process usually adopts the crushing-screening-sorting process, but there is a problem of insufficient efficiency of the classification equipment. For example, although the traditional vibrating screen has good classification effect, it has small processing capacity and the screen mesh is easy to wear, and it is difficult to cope with the scene of wide particle size distribution and complex dissemination characteristics of ore. In addition, although the artificial intelligence sorting machine based on deep learning (such as the name of the optical product) has realized the processing capacity of 150 tons / hour and the recognition accuracy of 99%, its performance depends on the uniformity and particle size consistency of the feed. The existing system usually directly visually sorts the mixed ore with wide particle size, and has the following problems: 1. Fine ore: because of its small volume and unclear characteristics, it is easy to be ignored or misjudged in mixed sorting, resulting in metal loss.

[0003] 2. Large ore: it may block the subsequent ore, resulting in missed detection; the complexity of its surface characteristics (such as texture and color) also requires higher image resolution and more complex algorithm processing, which is difficult to meet the accurate identification of large and small particles under the same visual parameters.

[0004] 3. Difficulty in equipment optimization: the blowing parameters (such as valve opening time and pressure) designed for a single particle size cannot simultaneously adapt to ores of different weights and sizes, resulting in low efficiency of the sorting actuator. SUMMARY
