白土矿物超细磨中助磨剂的研究

对某地白土矿超细磨助磨剂的研究结果表明，四种表面活性剂的助磨效果顺序是石油磺酸钠＞ＴＦ２７９＞三乙醇胺＞油酸钠。当石油磺酸钠用量为０．１５５％时，其－５００目产率可由７６．５％提高到８４．９％，增量为８．４％。ＮａＯＨ、Ｎａ２ＣＯ３和六偏磷酸钠三种无机盐对白土矿物亦有一定的助磨效果，当碳酸钠加入量为０．１５％时，其－５００目产率增加了７．４％。助磨剂能明显提高粉磨效率。

Study on grinding aids in ultra-fine grinding of argil mineral

Study results on grinding aids in ultra-fine grinding of somewhere argil mineral show that the effectiveness sequence of four surfactants is sodium oil sulfonate>TF 279 >tricthanolamine >sodium olcate. The yield of -500 mesh mineral can inercased by 8. 4 %, from 76. 5% to 84. 9%,at the consumption of sodium oil sulfonate 0. 155 %. some grinding cffectiveness can also be obtained in grinding argil mincral by using sodium hydroxide,sodium carbonate,sodium hexametaphosphate as grinding aids. The yield of -500 mesh mineral can increased by 7. 4% at the consumption of sodium carbonate 0. 15%. Grinding cffectiveness can be evidently incrcasedby using grinding aids.
