Description

Technical Field

[0001] The utility model relates to the technical field of hydrometallurgy, in particular to a selective material crushing system. Background Technique

[0002] In recent years, with the rapid economic development, industries such as mining, metallurgy, chemical engineering, and new energy manufacturing have great development prospects. Among them, hydrometallurgy is to contact the valuable metal components in ores, concentrates, or other materials with leaching agents and dissolve them in solutions or precipitate them as new solids to achieve the purpose of metal separation, enrichment, and extraction. Due to the different properties of materials such as hardness, moisture content, and size, direct leaching will greatly affect production efficiency and the recovery rate of valuable metals. In order to improve the production efficiency and resource recovery rate of enterprises and reduce the loss of machines, crushers, grinders, etc. have been widely used in the front-end processing of materials.

[0003] According to a solid waste crushing device disclosed in the patent with the publication number CN220835814U, a driving structure, a moving structure, and a cleaning structure are provided, which can clean the solid waste residues adhering to the crushing rollers. This application not only improves the efficiency of subsequent crushing of solid waste by the crusher but also reduces the generation of pungent odors, which is more beneficial to the health of workers. However, the above solution uses one-stage crushing treatment. For materials with high hardness and compressive properties, they cannot be fully crushed. After crushing, there are still many large-particle materials, which need to be manually selected and crushed again, resulting in repeated crushing work, low crushing efficiency, high energy consumption, greatly reducing the service life of the crusher, and finally directly affecting the metal recovery efficiency.

[0004] And the patent with the publication number CN117181420B discloses a decoration waste sorting and crushing system, including a sorting device and a crushing device. The sorting device includes a conveying mechanism, a wind selection mechanism, and a magnetic separator. The crushing device includes a primary crusher and a secondary crusher. The secondary crusher includes a housing, a main shaft, and a grinding head, and a movable ramming plate is arranged on the grinding head. However, it must be linearly processed through the primary crusher and the secondary crusher in sequence. In actual situations, if the material to be processed has low hardness and high moisture content, the primary crusher can achieve the crushing requirements, and using two-stage crushing will cause waste and affect efficiency. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a selective material crushing system. For materials with low hardness and high moisture content, the crusher is directly used for treatment, while for materials with high hardness and large particle size, a two-stage crushing treatment of first crushing and then pulverizing is adopted. This selective crushing method not only improves work efficiency but also reduces the blockage of materials in pipelines, shortens the reaction time of subsequent hydrometallurgy, and improves the metal recovery rate.

By controlling the forward and reverse rotation modes of the fourth conveying unit 6, the materials can be directly controlled to enter the leaching reaction tank 8 that needs to be fed, which is simple, convenient, and saves manpower and material resources.

[0039] Working process and principle:

[0040] Coarse crushing mode: Control the third conveying unit 5 to move above the first conveying unit 3, pour the materials to be processed into the feed port of the coarse crushing unit 1. After the materials are preliminarily screened by the grid 7, they are crushed into coarse crushed materials with a particle size of about 2 cm by the coarse crushing unit 1, and then enter the leaching reaction tank 8 corresponding to the coarse crushed materials through the third conveying unit 5, the magnetic separator 9 for impurity removal, the second conveying unit 4 and the fourth conveying unit 6, waiting for subsequent processing.
