Kaolin calcining rotary kiln technology of low energy consumption, high yield, product by dehydration, stable performance, used in papermaking and coating industries, products listed since calcined kaolin ultrafine technology mature, domestic advanced. It represents the development direction of ultra-fine calcined kaolin.

Kaolin Rotary Kiln Technology

Kaolin Rotary Kiln is an important equipment in the production of kaolin, the general requirements of rotary kiln temperature to reach more than 950. Alias: Kaolin Rotary Kiln kaolin calcining kiln. At the same time can also be used for alumina calcining kiln, kiln kiln, Zinc Oxide Magnesium Oxide. Kaolin has a high degree of whiteness, soft and easy to disperse in water. With good plasticity and high adhesion, excellent electrical insulation properties, good acid soluble and low cation exchange capacity, good fire resistance and other physical properties.

Internal heated rotary kiln temperature (950 DEG C to 1050 DEG C) superfine kaoline calcining technology, mature, domestic advanced, on behalf of the ultra-fine calcined kaolin technology development direction. The calcination technology of low energy consumption, high yield, product by dehydration and decarbonation whitening and stable performance.

Calcined kaolin has become a paper, ceramics, rubber, chemicals, coatings, medicine and national defense industries, such as the necessary mineral raw materials. The kaolin application areas are more extensive and some high-tech fields began to make extensive use of kaolin as new materials, high temp porcelain parts even atomic reactor, aerospace, aircraft, and spacecraft, with kaolin made.

Application of Kaolin Rotary Kiln

Kaolin in the paper industry, there are two main areas, one is in the paper (or copy paper) process used in the filler, and the other is in the process of surface coating used in the paint.

Rotary kiln calcined kaolin is a widely used method for producing special kaolin products. It has 4 calcination temperature range:500~700℃、925℃、1000℃、1400℃.Calcined at different temperatures, the resulting product applications are different.Only elimination of hydroxyl group from calcined kaolin used as cable plastic and rubber sealing ring filler; by 1000 ℃ calcined kaolin can behalf of Tio2, as a paper filler;by 1300 ~ 1525 ℃ calcined kaolin refractory products used as fillers, optical glass crucible inner lining.

Working principle of Kaolin Rotary Kiln

On the one hand, it is the burning equipment, which produces heat in the combustion of coal, while the heat transfer equipment, and the heat of the material absorbs the gas to be burnt. In addition, sometimes the conveying equipment, the raw material from the feed end to the discharge end. And fuel combustion, heat transfer and raw material must be reasonably fit to make fuel combustion heat energy in the raw materials by rotary kiln rotary kiln in raw materials, to achieve the purpose of high yield, high quality, low consumption.

A, using the most advanced hydraulic gear at home and abroad.

B, the metering plunger pump with high measuring accuracy.

C, high precision speed control valve and contact type graphite block sealing device and other domestic advanced technology.

D, convenient operation, reliable use.

E, stable thermal system, improve the operation rate of equipment.

F, compared with the same specifications, operating rate increased by 10%, the yield increased by 5%-10%, heat consumption decreased by 15%.
