Description

Technical Field

[0001] The invention relates to a fluorite particle screening device, in particular to a conveying type ore dressing fluorite particle screening device. Background Art

[0002] Fluorite, also known as fluorspar, is the primary source of fluorine in industry and one of the world's 20 most important non-metallic mineral raw materials. Pure, colorless, and transparent fluorite is used as an optical material, while its vibrant luster is also used as gemstone and as a raw material for arts and crafts carving. Fluorite is also a fundamental raw material in the fluorine chemical industry, with products widely used in aerospace, aviation, refrigeration, medicine, pesticides, corrosion protection, fire extinguishing, electronics, electricity, machinery, and atomic energy. With the continuous development of science and technology and the national economy, fluorite has become a vital mineral raw material in modern industry, and many developed countries reserve it as a strategic material. Due to the different hardnesses of fluorite powder and rock powder, after primary crushing in a jaw crusher, large fluorite ore is broken into a mixture of lump rock particles, lump fluorite particles, powdered rock particles, and powdered fluorite particles. This mixture is typically further crushed into powder particles in a ball mill, and the fluorite powder is then separated from the powder particles by flotation. To do this, it is necessary to use a ball mill with large-particle ball milling function to grind the rock particles into fine powder and fine powder fluorite particles. Since the powdered rock particles and powdered fluorite particles mixed in the block rock particles and block fluorite particles can form fine powder rock particles and fine powder fluorite particles without excessive grinding, the existing practice not only reduces the working efficiency of the ball mill, but also increases the ball milling time, resulting in a serious waste of resources.
