摘要
研制的复合焙烧添加剂能显著提高焙烧转化率,焙烧烟气不经处理可达排放标准。与无盐焙烧工艺相比,生产成本可降低20%～25%,具有较好的经济效益。
The prepared composite additives could remarkably improve roasting conversion rate. The roasting flue gas that needn＇t be handled might come up to the emission standard. Comparing with the no salt roasting technique, the manufacturing cost of this method could be reduced 20% - 25%, and the better economical effects were obtained clearly.
