Through experiments in a high-shear mixergranulator,the proper operation conditions,such as the amount of water added during granulation,the time for granulation,the stirring speed for granulation as well as sintering temperature and temperature holding time,for preparing the macro-porous glass beads from waste glass material are determined.It shows that under the conditions of adding 41%-42% water,granulating for 3-6 minutes,sintering at 750℃and holding the temperature for 2 hours,the glass beads with poro...
