【摘要】 通过对水泥生料中fSiO2含量和粒度分布情况的测定,结果表明:生料率值相近时,当fSiO2含量相近,细度越粗,生料易烧性越差;当fSiO2细度分布相近,含量越多,生料易烧性越差;粒径<45μm的fSiO2含量对生料易烧性基本没有影响。更多还原

【Abstract】 The content and particle size distribution of free silica in raw meal was measured, the results showed that with a similar modulus value of raw meal and content of free silica, the coarser the raw meal. The worse the burnability of raw meal; while with a similar particle size distribution of free silica, the more free silica, the worse burnability of raw meal; and the effect of the fSiO2 could be ignored, if the free silica with particle size were less than 45μm.更多还原
