该水泥厂建于1958年,根据历年粉尘浓度测定情况,平均粉尘浓度为7.6~304.16mg/m~3,最高为1440mg/m~3,粉尘中游离SiO_2含量:生料为5.37~15.45%,熟料为1.58~4.6%;分散度:粉尘粒径在5μm以下者占89.59~90.47%。对453名水泥
The cement plant was built in 1958. According to the determination of dust concentration over the years, the average dust concentration is 7.6 ~ 304.16mg / m ~ 3 and the highest is 1440mg / m ~ 3. The content of free SiO_2 in dust is 5.37 ~ 15.45% Clinker 1.58 ~ 4.6%; Degree of dispersion: dust particle size below 5μm accounted for 89.59 ~ 90.47%. For 453 cements
