Technical Field

[0001] The utility model belongs to the technical field of micro powder grinding, in particular to a crushing and grinding device for processing ultrafine aluminum hydroxide. Background Art

[0002] Aluminum hydroxide has multiple functions such as flame retardant, smoke suppression, and filling. It does not produce secondary pollution and can produce synergistic flame retardant effects with a variety of substances. It is widely used as a flame retardant additive for composite materials and has become the largest environmentally friendly inorganic flame retardant. In order to achieve a certain flame retardant level, aluminum hydroxide needs to be selected using a screening device to select ultrafine aluminum hydroxide.

The grinding assembly includes a grinding chamber, a grinding plate, a powder selection column and a powder selection barrel. The lower end of the grinding chamber side is fixedly connected with an air inlet. The air inlet grinding chamber is installed along the tangent. The grinding plate is laid on the inner wall of the grinding chamber. The powder selection column runs through the top of the grinding chamber and connects to the collection assembly. The powder selection barrel is sleeved at the lower end of the powder selection column. The side wall of the powder selection barrel is a filter screen, and an air pump is provided in the collection assembly. This application screens the particles entering the powder selection column through the filter screen, and controls the particle size distribution range of the ATH powder through screening to make the particle size more stable.

[0004] However, when the above device is in use, the powder selection cylinder is rotated to reduce the agglomeration of powder on the filter screen and increase the powder selection efficiency. However, after long-term use, the powder will still agglomerate on the filter screen. When cleaning, the grinding chamber needs to be disassembled to clean the filter screen, which is cumbersome to operate and affects the production of aluminum hydroxide micropowder.
