Embodiment Construction
[0018] During specific implementation, combined with figure 1 Processing flow chart.
[0019] A processing technology of magnesium hydroxide flame retardant, comprising the following steps:
[0020] 1) Feeding: Select 325-mesh brucite powder and add it to the feeding bin.
[0021] 2) Wet grinding: raw materials are automatically added from the feeding bin to the wet mixing mill for grinding. Due to the different uses of the products, the product fineness is 2000 mesh, 3500 mesh, 6000 mesh, etc. According to the different requirements of product fineness, the product adopts secondary grinding process. When the fineness is less than 3000 mesh, the primary grinding process is adopted; when the product fineness is required to be above 3000 mesh, the brucite slurry is ground by the secondary grinding process and pumped into the storage tank.
[0022] 3) Pressure filtration: The brucite slurry stored in the storage tank is pumped into two filter presses for graded pressure filtr...
