摘要

首次采用蒸汽喷射研磨法对高岭土选矿厂生产的滤饼（含水量23.80%）进行了超细研磨。在研磨过程中，材料同时脱水和干燥，最终研磨的样品满足粉末产品的含水量要求<2%。研磨高岭土样品的粒度减小，粒度分布更加集中，表明蒸汽喷射研磨对高岭土的加工比传统的干法研磨更有效。此外，蒸汽喷射研磨可以提高高岭土的白度，降低样品的结晶顺序，从而在后续应用中改善高岭土的性能。

Effects of grinding and dehydration on kaolin in a steam jet mill

Steam jet milling was applied for the first time to ultra-fine grind the filter cake (moisture content 23.80%) produced by a kaolin concentrator. The material was dehydrated and dried simultaneously during grinding, and the final ground sample met the moisture content requirement for powder products of <2%. The particle size of the ground kaolin samples decreased and the particle-size distribution was more concentrated, indicating that the steam jet milling was more effective for kaolin processing than the conventional dry grinding process. In addition, steam jet milling can improve the whiteness and decrease the crystal order of the samples, thus improving the kaolin properties in follow-up applications.
