摘要:
对比棒磨和球磨条件下,黄磷尾渣-0.075 mm、-0.045 mm所占百分比与磨矿时间的关系,确定球磨为合适的磨矿方式;在球磨方式下,考察磨矿时间对黄磷尾渣的粒度特性和比表面积的影响;基于Rosin-Rammler-Bennet(RRB)分布方程建立模型,结果证实黄磷尾渣磨矿特性符合RRB分布. 黄磷尾渣超细粉的特征粒径(De)和比表面积对混凝土强度都呈现出先增大后减小的趋势,混凝土强度(凝结时间1 d)最大值在特征粒径为59.76 μm,比表面积为530.15 m2/g,黄磷尾渣掺量为25%时出现,为27.429 MPa.
Abstract:
The relation between the mass fraction of yellow phosphorus slag particles with -0.075 mm, -0.045 mm and the grinding time in the rod milling and the ball milling was investigated,indicating the ball milling being a better grinding method. Then,effects of the grinding time on characteristic particle size and specific surface area of yellow phosphorus slag were also studied in the ball mill. It was found that the size characteristics of slag were consistent with the Rosin-Rammler-Bennet (RRB) distribution through the model constructed by RRB distribution equation. As the characteristic particle size (De) and specific surface area of yellow phosphorus slag increases,the concrete strength increases firstly and then decreases. The maximum strength of 27.429 MPa (setting time 1 d) could be achieved when De,specific surface area and mixing amount of yellow phosphorus slag are 59.76 μm,530.15 m2/g and 25%,respectively.
