4 1.2.4 主要建设内容、规模 1、新增 3.213 米球磨机水泥粉磨生产线二条，形成年产 120 万吨生产能力； 2、部分辅助生产设施：中控室、配电站等； 3、土建工程需建筑厂房和设备基础、料库基础。 1.2.5 产品方案 本项目通过在原有生产工艺基础上，进行技术改造，建设 120 万吨年的水泥粉磨站，形成 120 万吨年的的水泥生产能力(其中 42.5 强度等级 75 万吨、32.5 强度等级 45 万吨、散装水泥达 70 以上)。 1.2.6 工艺技术方案 1.2.6.1 工艺方案选择 一、粉磨方案选择 目前国内水泥粉磨站通常采用的工艺技术方案有：方案一辊压 机+高细磨；方案二高细磨+高效选粉机。 该公司通过对国内许多水泥生产厂家的调研与比较分析，并根 据企业的实际情况， 、认为采用方案二比较合理，其理由是： 1、方案一投资规模较大，一台辊压机需 500 万元以上，而方

5 案二则比较低，一台高效选粉机包括土建在内仅需 70 多万元。 2、方案二的系统产量比较稳定，尽管采用方案一的系统台时 产量也可达到 9 0 吨以上，但工艺流程较为复杂，操作维护要求高， 系统稳定性较差，运转率较低。而方案二的系统台时产量 42.5 的水 泥可达 85 吨以上，生产 32.5 水泥的台时产量可达 90 吨以上。采用 球磨机配新型高效选粉机，因其具有耐用、可靠、适应性强、操作 维护简便、投资省等优点，仍是水泥粉磨系统首选方案，由于采用 了高效选粉机，也使粉磨效率较以往有所提高，鉴于上述情况，本 项目水泥粉磨采用 3.213m 球磨机、高效选粉机组成的闭路粉磨 系统，以生产 42.5 水泥台时 85 吨计算单线系统年产量可达 61.2 万 吨；以生产 32.5 水泥台时 90 吨计算单线系统年产量可达 64.8 万吨。 3、方案二粉磨系统装置的能耗低。方案一的一台辊压机需配电 机功率为 600kw，而方案二高效选粉机的功率只有 350 kw，这对于 企业十分有利，同时企业还通过少用峰电多用谷电的办法，节能效 果显著，可使得粉磨站的总体效益得到提高。 4、该企业采用的主要原材料：一是旋窑厂生产的熟料，一般在 产品出厂时都经过二次细碎，其细度小于 10mm；二是混合材料粉煤
