Products Description
In china,the best Kaonlin flint clay comes from zibo city, with good whiteness and luminosity.
For the Kaonlin flint clay, the standard raw materials contains 38% Alumina at least. After calcination, the content of Alumina is about 44% and Ferrum is less than 2%. It has stable composition, uniform texture, compact structure, shell shaped and white cross section, and is used to produce high-quality clay refractory.
Flint clay is a mixture of alumina and silicate. The main chemical components are Al2O3 and SiO2, and the impurities are mainly alkaline, ferrum, titanium oxides, and some organic compounds. The main mineral is kaolin.
All kinds of oxides play the role of help melting, which will reduce the refractoriness of raw materials. Therefore, the lower the impurity content, especially the lower content of sodium and Potassium Oxide, the higher the refractoriness is. The closer the ratio of Alumina is to the theoretical value , the higher the purity of pyrogem is. The refractoriness of high-quality Kaonlin flint clay can reach 1750 ℃.

Products Advantages
After calcined at high temperature, pyrogem has the characteristics of stable volume, high strength and low water absorption. The indexes to measure the sintering degree of pyrogem generally include true specific gravity, bulk density, porosity, water absorption, shrinkage, etc. The water absorption is less than 5% and the bulk density is more than 2.55g/cm3.
Products Applications
Kaonlin flint clay is used in the production of high-grade refractory materials, ceramics, aluminum silicate refractory fiber production and military industry.
Products Production Process
The first stage: the broken large pieces of Kaonlin flint clay are transported to the raw material warehouse by special vehicles, and then the materials are sent to the jaw crusher by forklift/manual for crushing until they are smaller than the feed size of the grinding mill.
The second stage: the Kaonlin flint clay crushed by the crusher is lifted by the elevator to the storage hopper. The material is discharged from the storage hopper and then the feeder evenly feeds the host machine.
The third stage: During the grinding process, qualified products are screened by the screening system and then enter the collector through the pipeline. After collection, they are discharged through the discharge valve to become the finished product. Unqualified products fall into the main machine and are re-ground.
The fourth stage: The purified airflow of the finished product flows into the blower through the residual air duct above the dust collector. The air path is circular. Except for the positive pressure from the blower to the grinding chamber, the airflow in the other pipelines flows under negative pressure, ensuring indoor hygiene. Better conditions
