Method and system for conducting ore presorting based on hierarchical arrayed intelligent sorting

A method for conducting ore presorting based on hierarchical arrayed intelligent sorting, comprising:

• acquiring parameter information of ores to be processed, and determining, according to the parameter information, the number of intelligent sorting devices and a sorting hierarchy structure of a plurality of intelligent sorting devices for hierarchical arrayed intelligent sorting, wherein the sorting hierarchy structure comprises at least two sorting hierarchies, and each of the sorting hierarchies comprises at least one intelligent sorting device;
• determining, according to the sorting hierarchy structure of the plurality of intelligent sorting devices, a granularity hierarchy structure for conducting multi-hierarchy granularity processing on the ores to be processed, wherein the granularity hierarchy structure comprises at least two granularity hierarchies;
• associating each sorting hierarchy in the sorting hierarchy structure with a corresponding granularity hierarchy in the granularity hierarchy structure to form a multi-hierarchy ore processing structure comprising at least two processing hierarchies;
• and
• conducting ore presorting on the ores to be processed based on the multi-hierarchy ore processing structure so as to acquire ores that meet a predetermined granularity;
• the sorting hierarchy structure of a plurality of intelligent sorting devices for hierarchical arrayed intelligent sorting comprises a first sorting hierarchy, a second sorting hierarchy and a third sorting hierarchy;
• and the granularity hierarchy structure comprises a first granularity hierarchy, a second granularity hierarchy and a third granularity hierarchy;
• cyclically conducting primary crushing and primary sieving on the ores to be processed by using crushing processing of the first granularity hierarchy to acquire ores within a first crushing granularity range and ores within a second crushing granularity range;
• conducting sorting on the ores within the first crushing granularity range by using each intelligent sorting device in the first sorting hierarchy to acquire waste, primary concentrates and primary middlings;
• cyclically conducting secondary crushing and secondary sieving on the primary middlings and the ores within the second crushing granularity range by using crushing processing of the second granularity hierarchy to acquire ores within a third crushing granularity range and ores within a fourth crushing granularity range;
• conducting sorting on the ores within the third crushing granularity range by using each intelligent sorting device in the second sorting hierarchy to acquire waste, secondary concentrates and secondary middlings;
• cyclically conducting third crushing and third sieving on the secondary middlings by using crushing processing of the third granularity hierarchy to acquire ores within a fourth crushing granularity range and ores within a fifth crushing granularity range;
• conducting sorting on the ores within the fifth crushing granularity range by using each intelligent sorting device in the third sorting hierarchy to acquire waste and third concentrates;
• and
• the second sorting hierarchy and/or the third sorting hierarchy comprise/comprises a plurality of intelligent sorting devices connected in parallel.
