Kaolin is a non-metallic mineral, a kind of clay and clay rock dominated by kaolinite clay minerals. Because it is white and delicate, it is also called white cloud soil. It is named after Gaoling Village, Jingde Town, Jiangxi Province. The pure kaolin is white, fine, soft and soft, with good plasticity and fire resistance.
Abstract. 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%.

Industrial kaolins, which encompass pure kaolin, refractory clays, and bauxitic kaolin, among others, are distinguished by their relatively high content of clay minerals from the …
Mechanical treatment of kaolins was carried out in a Planetary Micro Mill. The samples, (m = 7.5–10 g), were ground in a water suspension, using different sizes of ZrO 2 balls and the necessary grinding time, in order to produce samples with d 50 of 0.5 μm, approximately. Details of the grinding conditions are listed in Table 2.The fineness …
However, the grinding process would be neither difficult nor costly due to the low hardness of aluminosilicates (1–2 on the Mohs scale). ... Izabella, and Krzysztof Matus. 2023.
