[0002] Aluminum hydroxide flame retardant is a halogen-free, environmentally friendly flame retardant whose main component is aluminum hydroxide, with the chemical formula Al(OH). It not only has flame retardant properties, but also suppresses smoke, does not produce droplets or toxic gases, and is relatively inexpensive. It is the most widely used of the inorganic flame retardants and is widely used in various materials, including plastics, rubber, coatings, and textiles. Due to its non-toxic, non-corrosive properties and the absence of harmful gases, aluminum hydroxide flame retardant performs well in terms of environmental protection and fire safety.

[0003] During the production of aluminum hydroxide flame retardant, various raw materials need to be crushed so that the multiple raw materials can be mixed together and interact with each other. When crushing the aluminum hydroxide flame retardant raw materials, the operator needs to pour the raw materials into the interior of the crushing device for crushing. However, the production volume of aluminum hydroxide flame retardant is large, and during its production, the raw materials need to be continuously added to the interior of the crushing device for crushing.
