Description

Technical Field

[0001] The utility model relates to the technical field of activated alumina production, in particular to a raw material crushing device for activated alumina production. Background Art

[0002] Activated alumina is a porous alumina material that has been specially treated to have a high specific surface area, developed pores, strong adsorption capacity and high catalytic activity. Its chemical formula is generally expressed as Al2O3·nH2O (where 0<n<0.8). It is obtained by high-temperature dehydration of aluminum hydroxide (Al(OH)3). It contains a large number of pore structures inside, which give it unique physical and chemical properties.

[0003] The activated alumina production raw material crushing device is a mechanical equipment specially designed for crushing and refining the raw materials required for the production of activated alumina. These raw materials usually include aluminum hydroxide, alumina ore, secondary recycled alumina waste, etc. The crushing device uses mechanical force to grind large pieces of raw materials into fine powder with uniform particle size suitable for subsequent processing. In the production process of activated alumina, the crushing process is very important because it can increase the surface area of ​​the raw materials, which is beneficial to subsequent chemical reactions and physical modifications. The crushing device can be used to refine the raw material particles to a specified particle size range to ensure that activated alumina products with high activity and excellent physical properties are obtained in subsequent molding, drying, roasting and other steps.

[0004] However, in actual use, it is found that because the raw material crushing device usually grinds the raw material into powder at one time and grinds it to extremely fine particle size at one time, the grinding equipment needs to bear a greater load, resulting in increased energy consumption and increased wear of the equipment, resulting in excessive energy consumption and rapid wear of the equipment. Utility Model Content
