| description | The invention relates to a method for preparing hollow glass bead, which comprises following steps: (1) preparing natrium silicate and boron, feeding them into spray drying machine, drying with temperature being inlet air of 180-300 Deg. C, and outlet being 120-145 Deg. C, collecting powder, which is solid spherical with diameter being 5-50 um; (2) feeding said powder from upper part of high temperature main tower of hollow glass bead energy-saving furnace, the temperature of inlet air in upper part is 400-650 Deg. C, the powder falls into the first and second under action of air force from air fan and normal air force from hole in lower part of pyramidale during falling from upper section to lower section. The temperature in lower pyramidale outlet is 115-150 Deg. C. The invention is characterized by simple construction of device and convenient preparation process. |
