The invention discloses a high-temperature fire-proof material granulating method, which is characterized in that: first the material enters the material
distributor, to be forced by three horizontal wing-shape mixing lodicules and
vertical mixing shovel to make frequency variable speed-adjustable circle motion, therefore, the material can writhe by the shearing forces in
horizontal and vertical directions to attain uniform material; wherein, the set granulating condition comprises: time: 800-1000s; temperature: 40-50Deg. C; and when reaching said condition, opening the vacuum valve, to adjust the pressure in -0.06-0.08MPa, and the mixing lodicules and
shovel granulate in variable speed again, and vacuuming the gas of mixed material to improve the density more, reduce the hole rate and improve eth size and uniformity of particles.
