Description

Technical Field

[0001] The utility model relates to the field of crushing devices, in particular to a crushing device suitable for spodumene crystal structures. Background Art

[0002] The crystal structure of pegmatite-type aluminosilicate minerals such as spodumene, feldspar and mica is complex, and the structural unit layers are composed of aluminum oxygen octahedrons and silicon oxygen tetrahedrons. Such similar structures will lead to similar surface chemical properties of these minerals. The surface active particles are mainly aluminum ions, which makes flotation more difficult. However, there are still large differences in the crystal structure of these aluminosilicate minerals. Feldspar is a framework-structured aluminosilicate mineral, mica is a layered-structured aluminosilicate mineral, and spodumene is a chain-structured aluminosilicate mineral.

[0003] There are five common ways to crush lithium ore, including crushing, splitting, grinding and impact. Usually, several crushing methods are used in combination. In the process of ore becoming smaller, various useful mineral ions are dissociated in the process of ore particle size becoming smaller. In the crushed ore, various minerals that were originally connected together are crushed into small particles containing only one mineral. However, in mineral crushing, there are often phenomena of insufficient dissociation and over-grinding, that is, the mineral product is too coarse and the dissociation is not sufficient, and the grade and recovery rate of the selected concentrate are relatively low; the grinding product is too fine. Although the mineral monomer is fully dissociated, the fine particles produced will be adsorbed on the surface of the monomer particles, affecting the subsequent flotation process, increasing the amount of reagents used, and also reducing the grade and recovery rate of the concentrate. The existing crushing methods are prone to the disadvantages of over-grinding and insufficient dissociation.

[0004] Therefore, it is necessary to provide a crushing device suitable for the spodumene crystal structure to solve the above technical problems. Utility Model Content
