Currently, the main flame retardants used are inorganic, organophosphorus, and organohalogen. Each type of flame retardant has its own unique properties and advantageous application areas. During the production of flame retardants, a temperature-controlled stirring device for flame retardant production is required to stir and mix the raw materials.

[0003] The existing temperature-controlled stirring device for flame retardant production uses a motor to drive the rotating shaft to drive the stirring blade to stir and mix the flame retardant production raw materials.
