目前,我国水泥企业使用的蓖冷机多为第二代或第三代产品,这些蓖冷机已经不能满足生产的要求,特别是回转窑提产后,更感蓖冷机冷却能力不足。主要表现为:热效率低、出料温度高、故障率上升、备品备件消耗量大,严重影响或威胁水泥窑的长期安全运转,成为烧成系统中的薄弱环节。 At present, our country’s cement enterprises are mostly used for second-generation or third-generation products, which have not been able to meet the production requirements, especially after the rotary kiln is put into production. Mainly as follows: low thermal efficiency, the material temperature is high, the failure rate increases, the spare parts consumption is large, seriously affecting or threatening the long-term safe operation of cement kiln, become the weak link in the firing system.
