1、十个基本规则熟料UpdateLAFARGEDuJiangYan-ZhouXia.ZhuFang(fromHuaiBeiversion)–July03-V1.12UpdateLAFARGEDuJiangYan-ZhouXia.ZhuFang(fromHuaiBeiversion)–July03-V1.12规则一降低生料的筛余尤其是硅质筛余会降低煅烧温度和粉磨电耗。同时会有利于提高强度。关键数值？当100μm的筛余量由20%降至10%，水泥细度为350m2/kg时.每吨水泥总的研磨电耗会下降4kWh。UpdateLAFARGEDuJiang

2、Yan-ZhouXia.ZhuFang(fromHuaiBeiversion)–July03-V1.12将节省煅烧所用燃料水泥研磨电耗将生料研磨得更细一点UpdateLAFARGEDuJiangYan-ZhouXia.ZhuFang(fromHuaiBeiversion)–July03-V1.12CONTES更细的生料=节省燃料55.55656.55757.55858.58121620油(升/吨生料)>100µm筛余(%)UpdateLAFARGEDuJiangYan-ZhouXia.ZhuFang(fromHuaiBeiversion
