Kaolin, which was discovered in China, has been used for millennia in the manufacturing of porcelain and fine china. Kaolin is currently used as a substantial and cost-effective pigment in various papers, ceramics, cement, and cosmetic goods. Now you might wonder, why is it shaped like a noodle? What makes it different from other types of kaolin? While the noodle version of kaolin has a long shape, its use is no different from any other type of kaolin.
In hindsight, kaolin looks to be unremarkable. The appearance of kaolin, a platy soft white clay, can disguise its adaptability and usefulness in a variety of industries. Kaolin is available in several forms, including kaolin powder, kaolin lump, and kaolin noodle, all of which are extensively treated to provide a high-quality product.
If you’re seeking additional information about kaolin, its kinds, and applications, go no further because we’ll go over all you need to know about kaolin noodles and more!
How was Kaolin Noodle Made?
Before it can be utilized in industrial operations, kaolin noodle has gone through a lengthy procedure. Because kaolinite is a mineral found in the ground, it must first be mined, generally done by water jet mining. Following that, kaolinite goes through a process known as centrifuge kaolin slurry. The sand is removed, and kaolinite may proceed to its first filtering process, which uses a 100 mesh screen by the second and third, which employ 200 and 325 mesh screens.
After being filtered, kaolinite will be purified and solidified using a high-pressure pump and filter press. This stage contains kaolin clay or a lump with a moisture content of about 33-35 percent. In this stage, you’ll also meet with a high moisture version of the noodle which consists of 33-35% moisture.
However, if you wish to have a noodle version of kaolin that possesses a lower moisture level, it will have to go through a natural drying process until the moisture level is decreased to around 12-14%. This noodle is considered to have a middle-level of moisture, unlike kaolin powder that only has around 1-4%.

To achieve that moisture level, the kaolinite must undergo another drying and milling process using a disc milling machine beforehand. The machine will destroy its noodle shape and mill it into powdery substances that you can combine and mix into a variety of industrial needs.
Without a doubt, the procedure from beginning to conclusion is lengthy. This is why selecting the correct kaolinite is critical, as you must guarantee that the kaolin noodle remains of excellent quality even after going through so many procedures.
How Do You Use Kaolin Noodle?
Similar to other types of kaolin, noodle-shaped kaolin possesses a lot of potential in terms of use cases. The reason is that it’s multifunctional, flexible, hence making it suitable for a range of industries. Wondering which industry that employs kaolin noodle in its process? Here are some of them!
1. Sanitaryware Industry
Sanitaryware, wall and floor tiles, and tableware are the most common ceramic ware forms that use kaolin. When burned, kaolin powder creates a white hue, giving the sanitaryware a beautiful and strong appearance. This enables the ceramic body to be securely shaped and handled during the shaping and firing processes.
Kaolin is also used for its casting properties, which are important in slip casting, especially in the manufacturing of safe, family-friendly sanitaryware.

Many people assume that the sole use for kaolin is in the manufacture of china. This is not the case, as its use in the paper industry much outnumbers its other applications. Kaolin, on the other hand, is still used in the production of china and other dinnerware. Its color, gloss, and hardness make it ideal for such applications.
4. Agriculture Industry
Kaolin has an aluminosilicate particle covering that is sprayed on crops right away. By interfering with feeding behavior and egg-laying, increasing mortality, visually or chemically concealing the crop, and lengthening developmental time, the film minimizes insects and disease. Kaolin has been shown to reduce the number of thrips and weevils, as well as other diseases caused by insects.
