Kaolin crushing plant is the fine grinding process,hard kaolin in the process of wet superfine grinding,solid concentration is the main factors affecting the grinding efficiency and slurry rheological property.when the concentration is 30% to 50%,the slurry viscosity with the increase of concentration of exponential rule,grinding efficiency,yield value rises with the concentration increased,slurry by the transition of fluid expansion and trigger.after anionic dispersant was added,the slurry viscosity decreased significantly.reduce the viscosity to improve slurry flow,it is necessary to improve the grinding efficiency.
Kaolin resources distribution: kaolin resources are rich, ore deposits are widely distributed in China, the country has 16 provinces have output, but mainly distributed in the southeast coastal area. East China, central south region for 80% of the total reserves proved reserves in jiangsu, zhejiang, fujian, jiangxi, hunan, guangdong and other provinces, in sichuan, guizhou, yunnan, hebei and liaoning provinces. Across the country, including ceramic clay, kaolin deposits, a total of more than 200 but large deposit less, more for medium and small. Main deposit: suzhou, jiangsu province, sichuan XuYong, wenzhou, zhejiang, guangdong, liaoning dandong Ann, maoming, zhanjiang, fujian series, minqing, deep, hunan hengyang, hengshan, liling, shanxi datong, jingdezhen in jiangxi province, shaanxi los south, zibo in shandong province and the Tibet yambajan deposit. More than 60 countries across the world in the production of kaolin. The United States, China, Britain, Russia, Brazil is the world's superpower kaolin resource and production, 68% of the world kaolin proven reserves.
Kaolin crushing plant is kaolinite by artificial hand picking,according to level classification,with the jaw crusher coarse crushing to 10mm below,enter the ultrafine grinding mill to 2500 mesh. To make in the process of abrasive particle size stability control, need to feed concentration, feed flow rate, grinding medium, dispersant, grinding time and several parameters to control them.
