Preparation method of self-humidifying portland pozzolana cement
The invention discloses a preparation method of self-humidifying portland-pozzolana cement, and belongs to the field of portland cement, the preparation method of the self-humidifying portland-pozzolana cement comprises the steps of raw material preparation, raw material homogenization, preheating decomposition, clinker firing, cement grinding, material adding and stirring, and quality inspection and warehousing, when cement is ground, the attached type refining grinding roller is additionally arranged to assist grinding of cement clinker and improve the grinding fineness of the cement clinker, so that the mixing saturation degree of the ground fine powder and a humidifying agent is effectively improved, and the autonomous humidifying performance of portland-pozzolana cement in subsequent use is conveniently improved, so that the service life of the portland-pozzolana cement is prolonged, and the service life of the portland-pozzolana cement is prolonged. The grinding fineness of the cement clinker is improved by additionally arranging a mechanical structure, the preparation difficulty of the self-humidifying portland-pozzolana cement is effectively reduced, the technical requirements on technicians are reduced, batch production of the cement is facilitated, and the economic benefit of preparation of the self-humidifying portland-pozzolana cement is further improved.
本发明公开了一种自增湿火山灰质硅酸盐水泥的制备方法，属于硅酸盐水泥领域，一种自增湿火山灰质硅酸盐水泥的制备方法，包括生料制备，生料均化，预热分解，熟料烧制，水泥粉磨，添料搅拌，质检入库，它通过在水泥粉磨时增加贴合式细化研磨辊，以辅助水泥熟料的研磨，提高水泥熟料研磨的精细度，进而有效提高研磨好的精细粉末与增湿剂的混合饱和度，便于提高火山灰质硅酸盐水泥后续使用中的自主增湿性能，并且通过增设机械结构的方式来提高水泥熟料的研磨精细度，有效降低该自增湿火山灰质硅酸盐水泥的制备难度，降低对工艺人员的技术要求，利于该水泥的批量生产，进而提高自增湿火山灰质硅酸盐水泥制备的经济效益。
