水泥粉磨配料调整矿粉掺入比例的研究

Study on blending proportion adjustment of slag powder in cement grinding proportioning

生产P·O42.5优等品水泥时,通过调整矿粉掺入比例来提高磨机产量,以满足不同季节水泥市场的需求。矿粉的掺加比例直接影响水泥的价格成本、化学指标和物理性能,本文从实际生产阐述了在P·O42.5水泥生产中熟料、粉煤灰、石灰石掺量做相应调整的情况下,研究外掺矿粉从5%提高到15%,P·O42.5水泥的价格成本、化学指标和物理性能的变化。

Producing P·O42.5 superior cement by means of adjusting blending proportional of slag powder to improve mill output to meet the demand of the cement market in different seasons. The blending proportional of slag powder directly influence the cost, chemical index and physical properties of cement. Under the corresponding adjustment of clinker, fly ash and limestone content in actual production of P·O42.5 cement, the change of cost, chemical index and physical properties of cement with increasing of slag powder blending proportion from 5% to 15% were studied.
