Description

Technical Field

[0001] The utility model relates to the technical field of magnesium chip production, in particular to a magnesium chip crushing device. Background Art

[0002] Magnesium chips usually refer to the powder state of single magnesium. It is a silvery white powder with metallic luster. It is an active metal and flammable when wet. It produces strong white light and high heat when burning. It reacts with water or moisture to release hydrogen, releases a lot of heat, and causes combustion or explosion. It reacts violently with chlorine, bromine, iodine, sulfur, phosphorus, arsenic and oxidants, and is dangerous to combustion and explosion. Magnesium chips are mainly used as reducing agents, flash powder, lead alloys, and desulfurization agents in metallurgy (when used as desulfurization agent raw materials in the metallurgical industry, the magnesium chips are coated with a layer of passivation agent on the outside to prevent oxidation of magnesium chips). In addition, it is used in organic synthesis, lighting agents, etc. It is mainly produced by electrolytic molten magnesium chloride and electrolytic molten dehydrated carnallite. Ball mills are generally used for the production of magnesium powder and magnesium-aluminum alloy powder. That is, the raw materials are first milled into chips and added into the ball mill, and become powder under the impact of steel balls. However, during the crushing process, it generates a lot of dust under the impact of steel balls, which causes environmental pollution. In addition, through the continuous impact of steel balls, due to the uncertainty of the movement of steel balls, the particle size of magnesium powder is uncontrollable, affecting the crushing quality of magnesium powder. For this reason, we proposed a magnesium chip crushing device. Utility Model Content
