| In this paper the mechanism and operation process of preparing porous glass material by means of filling method that is an improved method of traditional filling method in the high-speed mixer are studied. Then the operation conditions including granulating conditions and sintering conditions are carefully studied. It turns out that the time of granulating, amount of water added during granulation, granulating time directly determine the success of granulation for glass beads and the sintering temperature and sintering time of beads have great effect the quality of porous beads. These effects are discussed in detail and the relationship between the factors is studied thoroughly.A high-speed mixer was employed as granulation equipment for the first time and the effects to the granulation in this machine was researched systematically. As showed by the experimental results, high-speed mixer is advantageous for the stable formation or growth of pre-sintered glass beads, and it can partly guarantee the desired results of sintering. Furthermore, the shape of product is uniform, pores with relatively large size are evenly distributed, and the strength and porosity are all improved to a certain extent. The preferred ranges of operation variables are presented on the basis of quantities of experiments. The suitable operating conditions are determined based on large number of conditional experiments. In granulation step, water content is 41-42%, granulating time is 3-6 minutes; in sintering step, sintering temperature is about 750℃ and the time is 2 hours. With those conditions, good quality carrier beads with pore size range 20012μm, porosity above 42%, strength above 13MPa can be obtained in quantities.Furthermore, for scaling-up of this innovative process, it is necessary to set up a granulation model for the specific experimental conditions. A Population Balance Method (PBM) here was used for modeling this system which was expected to...
