Kaolin is a non-metallic mineral, a clay and clay rock dominated by kaolinite clay minerals. Named after Gaoling Village, Jingdezhen, Jiangxi Province. The pure kaolin is white, fine and soft, with good physical and chemical properties such as plasticity and fire resistance. Its mineral composition is mainly composed of kaolinite, halloysite, hydromica, illite, montmorillonite and quartz, feldspar and other minerals. Kaolin is widely used in paper, ceramic and refractory materials, secondly in coatings, rubber fillers, enamel glazes and white cement materials, and in small quantities in plastics, paints, pigments, grinding wheels, pencils, household cosmetics, soaps, Industrial sectors such as pesticides, medicine, textiles, petroleum, chemicals, building materials, and national defense.
The hollow hollow shaft of the kaolin special blade dryer is densely arranged with wedge-shaped hollow pulp leaves, and the heat medium flows through the blade through the hollow shaft. The heat transfer area in the effective volume per unit is large, and the temperature of the heat medium is from -40 ° C to 320 ° C. It can be water vapor or liquid type: such as hot water and heat transfer oil. Indirect conduction heating, no air is carried away to remove heat, and heat is used to heat the material. The heat loss is the heat dissipation to the environment through the insulation of the body. The wedge-shaped blade heat transfer surface has a self-cleaning function. The relative movement of the material particles and the wedge surface produces a scrubbing action, which can wash away the adhering material on the wedge surface, so that a clean heat transfer surface is maintained during operation. The shell of the paddle dryer is of the omega type, and two to four hollow agitating shafts are generally arranged in the casing. The housing has a sealed end cover and an upper cover to prevent material dust from leaking out and fully functioning.
The heat transfer medium passes through the rotary joint and flows through the casing jacket and the hollow agitating shaft. The hollow agitating shaft has different internal structures according to the type of the heat medium to ensure a good heat transfer effect.
