高分子助剂在浮选精煤脱水中的应用

Study on Application of Polymer Assistant in Coal Flotation

细粒精煤的脱水一直是选煤行业未得到很好解决的问题。精煤中的水分过高 ,不仅会影响生产效率 ,增加生产成本 ,还会影响煤的热效率 ,甚至给生产带来一些安全隐患 ;本文利用高分子的表面作用 ,采用浮选精煤预处理工艺 ,可以使精煤中的水份降低 8%左右 ,效果良好。

Water content in cleaned coal could be decreased 8% by using pretreatment technology and surface action of high polymer in coal flotation.Some results in series of experiment were very good.
