Copper smeltery middle return material processing system and technology

Abstract

The invention discloses a copper smeltery middle return material processing system and a technology, the system comprises a coarse crushing device and at least two fine crushing devices; a tail end ofthe coarse crushing device is provided with the at least two fine crushing devices, and a discharge end of the coarse crushing device is connected with a feeding end of a first fine crushing device of the at least two fine crushing devices; each of the at least two fine crushing deices is orderly arranged end to end, the discharge end of the fine crushing device located at a front side is connected with the feeding end of the fine crushing device located at a rear side; the discharge end of the last fine crushing device of the at least two fine crushing devices is connected with the feeding end of a vibrating screen, and a discharge port of the vibrating screen is connected with a feeding port of a grinding device. The system and the technology provided by the invention can continuously and stably process a high-rigidity and high-malleability middle return material of a copper smeltery, and after being processed, the middle return material can be directly used as a furnace burden to be returned back to a smelting system, thus, the system and the technology provided by the invention have the advantages of being environmental-friendly, low-investment, highly automatic, and so on.

Description

technical field [0001] The invention relates to the technical field of copper slag treatment, in particular to a copper smelter intermediate return material treatment system and process. Background technique [0002] In recent years, copper production has grown rapidly. In 2019, my country's copper production was 9.784 million tons. At present, 80% of the world's copper production is produced by fire method, which will produce a large amount of blowing slag and refining slag. Due to the high copper content of blowing slag and refining slag, returning to the smelting system is the best treatment process. However, the particle size of the returned material will seriously affect the normal production of the smelting system. [0003] Most of the traditional copper smelters in my country are equipped with a converter blowing process, which can coarsely crush the intermediate return materials such as refining slag, bottom copper, chute shell, etc., and then add them to the conver...
