(一)概况及技术性能粉煤灰陶粒是一种性能良好的人造轻骨料。国外用烧结机焙烧粉煤灰陶粒较普遍。我国从1960年开始研究和试制粉煤灰陶粒,开始用普通立窑,后过渡到机械化立窑。于1964年底开始了用烧结机焙烧粉煤灰陶粒的科研设计工作,1966年建成了年产7万米~3、用18米~2烧结机生产粉煤灰陶粒的工厂——天津市硅酸盐制品厂。经 (A) Overview and technical performance Fly ash ceramics is a man-made lightweight aggregate with good performance. It is more common to roast fly ash ceramsite with sintering machine in foreign countries. China began researching and trial-producing fly ash ceramsites in 1960, and began to use ordinary shaft kiln, and later transitioned to mechanized shaft kiln. At the end of 1964, the scientific research and design work for sintering fly ash ceramsite with a sintering machine was started. In 1966, a factory with an annual output of 70,000 m~3 and a 18 metre to 2 sinter machine was used to produce fly ash ceramsite—Tianjin City. Silicate product factory. through
