近几年来,水泥立磨终粉磨工艺因其流程简单、单位电耗低等显著特点,引起国内水泥企业的重视,逐渐得到应用。但采用立磨终粉磨工艺生产的水泥,其性能是否会逊色于辊压机+球磨机联合粉磨系统生产的水泥,是困扰企业是否推广采用立磨终粉磨水泥技术的一个关键问题。2012年5月,我公司下属一家采用立磨终粉磨工艺的水泥粉磨工厂投产运行,通过对其水泥样品的粒度分布、形貌特征和物理性能的分析检测,并与公司内装机产能占据70%左右的辊压机+球磨机联合粉磨工艺所生产的水泥样品进行了试验比较,以期为立磨终粉磨工艺在公司内部的推广应用提供依据。 相似文献

我厂是辊压机、高效选粉机和球磨机组成的半终粉磨流程,就辊压机在整个粉磨中所起的作用,可以认为是半终粉磨或部分终粉磨。但从另一角度看辊压机生产半成品,球磨机生产成品,二者联合生产产品,也可称为联合粉磨。流程图见图1,系统主机参数见表1。 相似文献

Solid solutions of diphosphates of zinc and copper and of zinc and cobalt were synthesized from mixtures of pure diphosphates at temperatures up to 1000°C. Their X-ray diffractometry patterns varied continuously from one end member to the other. Solid solutions of orthophosphates of composition Zn3−x Cox(PO4 )2, with x = 0.4–1.6, were formed at temperatures up to 950°C; all exhibited the structure of γ-Zn3 (PO4 )2. Solid solutions of orthophosphates of composition Zn3−x Cux (PO4 )2 exhibited more-complex behavior. At 1000°C and copper contents of 20–80 mol%, a phase that is related to Cu3 (PO4 )2, termed here the "ε-phase," predominated. At 850°–950°C and in the region from 20 mol% to ∼33 mol% of copper, the solid solutions (the "η-phase") adopted the structure of graftonite. At 800°–900°C and 10–15 mol% of copper, the solid solutions exhibited a new structure (the "δ-phase"), which we found to be related to the mineral sarcopside. At temperatures 950°C, the solutions that contained 5–15 mol% of copper (the "β-phase") had the structure of β-Zn3 (PO4 )2, whereas at 800°–850°C, solutions with 5 mol% of copper (the "-phase") exhibited the structure of γ-Zn3 (PO4 )2. Attempts to synthesize Cu+ ZnPO4 and Cu+ Cu2+ Zn3 (PO4 )3 were unsuccessful. 相似文献

Gel permeation chromatographic (GPC) and thin-layer chromatographic (TLC) studies of polystyrene, polybutadienes (BR), and their copolymers (SBR) have been carried out. GPC primarily separates them on the basis of molecular size, and TLC, on the basis of composition. Methods of obtaining absolute molecular weight distributions for BR and SBR based upon variations of the Strasbourg Universal Calibration procedure are described. In particular, [η]–M relationships in both the GPC solvent (THF) and in a second solvent (toluene) were used; in addition, results of statistical mechanical calculations for \documentclass{article}\pagestyle{empty}\begin{document}$\overline {s^2 }$\end{document} (based on the assumption of negligible steric hindrance and freely rotating bonds) were applied. An experimental comparison of these methods was carried out, and use of the [η]–M relationships for both solvents was found to give satisfactory results. The predictions of the statistical theory were too low. A detailed study of polymer–solvent–gel interaction in the GPC unit was made through investigation of ternary phase equilibrium in the (polystyrene)–THF–(polymer) system. The polymers studied included BR and SBR with varying styrene contents. Experimental techniques for TLC separations of BR, SBR, and polystyrene according to the composition are described. 相似文献
