摘要
在煤的超细磨碎中,添加合适的分散剂(如单宁酸,六偏磷酸钠)将有效地提高磨煤产量和产品细度。通过动电位和流变性的测定,以及分散剂作用原理的讨论,对分散剂的助磨作用机理获得了一些认识。
The experimental results show that adding tannic acid or sodium hexam-etaphospate in the fine grinding of coal would largely raise grinding efficiency. The mechanism of the dispersants for aiding grinding is discussed in this paper, through the determination of Zeta -potential and rheological behavior.
