| Abstract: | Experimental study on the crystallization of sand-like aluminum hydroxide was carried out in a spouted fluidized bed with a diameter of 100mm.As the main chemical and hydrodynamic factors the caustic mole ratios were controlled within 1.9 and the operating flow velocities were set 1.42×10-3,1.98×10-3 and 2.55×10-3（m/s） respectively.Their effects on the grain growth and formation of secondary crystal nucleus were obtained.The appropriate operation conditions were established for the sand-like aluminum hydroxide crystallization in the spouted fluidized bed. |
