The invention provides a cement admixture for cement admixture technology field, which is characterized by the following weight percentage: material accelerant 1.5 ~ 2.5%, 0.5 ~ 1.5% trace element additives, carrier 97.5 ~ 98.5%. This invention adopts the above scheme, compared with the existing technology for shaft kiln production can save more than 18% coal amount; cement increased to more than 30%; raw materials burning, burning, easy to wear fusible cement, reduce production costs and increase economic benefits. The utility model can be used in the rotary kiln to increase the yield of raw materials by more than 20%, and reduce the sintering temperature so that the mineral can be formed at low temperature, and the energy consumption can be saved by more than 25%. Alternative mineralizer and crystal, eliminated shaft kiln production in gypsum and fluorite is used as mineralizer containing SO emissions decrease 2 and fluoride, conducive to environmental protection. The utility model has the advantages of convenient use, easy matching, easy burning, easy grinding, and no knot, which can stop the accidents of shaft kiln spraying, complete combustion, less waste gas and favorable environment protection. The obvious effect of the utility model is that the heat consumption is reduced, the raw meal is easy to burn, the exhaust gas pollution is reduced, and the mixing quantity of the mixed material is increased, and the cement is easy to grind, and the labor intensity of the staff is reduced. The output of main console is improved, the production cost is lowered, and the economic benefit is improved.
【技术实现步骤摘要】
本专利技术属于水泥外加剂
,适用于现代立窑、回转窑等窑型的生料外加剂及应用。
技术介绍
目前,立窑普遍用石膏、萤石作矿化剂,煅烧产生的废气中含有氟、SO2,污染空气,在煅烧过程中易死结、挂边,抽心,并易发生喷窑事故,并且生料的易烧性不高,生料配煤量高,浪费能源。
技术实现思路
本专利技术的目的提供一种减少污染、在煅烧过程中不死结,不挂边,不抽心,杜绝立窑喷窑事故发生,提高生料的易烧性,降低生料的配煤量,提高立窑产质量、回转窑的外加剂及应用。本专利技术是由下列重量百分比的物质组成的助燃剂2.4~3.0%,微量元素添加剂1.7~2.3%,载体95.0~95.6%。每吨水泥生料掺入本外加剂的重量百分比为0.8~1.5%。由于本专利技术采用上述方案,其中助燃剂属化工类产品,用氯化钙,主要是帮助燃烧,促使高温熔融,降低煤耗,改善生料易烧性,提高成熟率,有利于矿物的形成及新矿物阿利尼特的生成。防止结窑及立窑喷窑事故。烧出的熟料对混合材有激活作用,可有效提高混合材的掺量,降低生产成本,提高经济效益。微量元素添加剂属化工类产品,用硼酸钠,可补充有助于煅烧的微量元素,增加活性,起到引气助熔作用,使生料易烧,从而降低游离氧化钙及烧失量的百分含量,加速矿化物的生成及转化,有效提高产品质量。载体属矿物质,它是冶炼选矿废弃的铅锌微粉,工业利用一是变废为宝,二是补充有利于煅烧的微量元素,掺入后生料易烧,煅烧易熔,熟料易磨。按照设计的配料方案把各种原燃材料准确计量配料,均化后投入到φ500mm×500mm的统一试验小磨中制得合格的全黑生料,然后人工成球,水份为14.5~15.5% ...
【技术保护点】
水泥统用生料外加剂,其特征在于是由下列重量百分比的物质组成的:助燃剂2.4~3.0%,微量元素添加剂1.7~2.3%,载体95.0~95.6%。
