日本神户钢铁厂发明以粉煤灰为主要原料,用水粘结造粒,置于移动火格子上,自然烧结成陶粒的方法。在粉煤灰中混合微煤粉等粉末材料,加水拌合,经过制粒后从料斗底口落在火格子上,火格子上有无数小孔,火焰通过格子可烧到上面的生陶粒层上。火格子做成运输带状,循环移动。生陶粒从运转机械的这一端落上火格子后,随着火格子移动到另一端时已经烧成,并 Japan’s Kobe Steel Co., Ltd. invented fly ash as its main raw material, bonded with water and pelletized, placed on a moving fire grid, and naturally sintered into ceramic pellets. Mixing powdered materials such as micro-pulverized coal in fly ash, adding water and mixing, after granulation, falling on the fire plaid from the bottom of the hopper, there are countless holes in the fire grid, and the flame can pass through the grid to burn the above ceramic granules. On the floor. The fire plaid is made into a transport belt and moves in a circular motion. After the raw ceramsite falls from the end of the machine to the fire grid, it is already fired as the fire plaid moves to the other end.
