Kaolin processing plant is used for manufacturing kaolin clay powder for paper coating and filling, refractories, fiberglass and insulation, rubber, paint, ceramics, and chemicals.
The kaolin clay powder production process features the separation of kaolin from quartz and feldspar by dry and wet processing.
The Kaolin dry processing line is simpler and produces a lower quality product than the wet process. Dry-processed kaolin is used mainly in the rubber industry, and to a lesser extent, for paper filling and to produce fiberglass and sanitary ware. Wet-processed kaolin is used extensively in the paper manufacturing industry.
The Kaolin processing plant equipment consists mainly of: Mining equipment, crusher, roller with classifier, hydrocyclone, thickener, bleaching equipment, filter press, dryer pulverizer, bagging.
Primary crushing reduces kaolin clay size from as much as one meter to a few centimeters in diameter and typically is accomplished using jaw crusher or gyratory crushers. Rotating pan crushers, cone crushers, smooth roll crushers, impact crushers, and hammer mills are used for secondary crushing, which further reduces kaolin particle size to 3 mm (0.1 in.) or less. For some applications, tertiary size reduction is necessary and is accomplished by means of ball, rod, or pebble mills, which are often combined with air separators. Screening typically is carried out by means of two or more multi-deck sloping screens that are mechanically or electromagnetically vibrated. Pug mills are used for blunging, and rotary, fluid bed, and vibrating grate dryers are used for drying clay materials. At most plants that calcine clay, rotary or flash calciners are used. However, multiple hearth furnaces often are used to calcine kaolin.
