Kaolin, also known as china clay, is a soft white mineral that plays an important role in various industries. Among its most valuable uses are in calcined clay production and paper coating applications, where particle size, purity, and brightness are critical for product performance. As industrial requirements continue to rise, modern kaolin processing demands more advanced, automated, and energy-efficient grinding technologies.

In kaolin production, raw kaolin ore is first crushed, refined, and then ground into fine powder. For calcined clay, the material undergoes thermal treatment after grinding to enhance its whiteness, hardness, and chemical stability. These characteristics make calcined kaolin an ideal additive for ceramics, rubber, and high-performance polymers. In paper coating, fine kaolin powder improves paper brightness, smoothness, and printability, helping manufacturers produce high-quality coated paper with excellent gloss and ink absorption.

Traditional mills often struggle with uneven particle distribution and high energy consumption, which can compromise kaolin's physical and optical properties. To overcome these challenges, Liming Heavy Industry provides a range of professional kaolin grinding solutions, including the MTW European Trapezium Mill, LM Vertical Mill, and MW Micro Powder Mill. These machines are designed with automatic feeding systems, precision classifiers, and intelligent control, ensuring consistent product fineness and stable operation.

The MTW European Mill is ideal for medium-fineness applications such as paper coating materials, while the MW Micro Powder Mill is capable of producing ultra-fine kaolin powders up to 3,000 mesh—perfect for calcined clay production and high-end coatings. These systems integrate drying, grinding, and classification into one operation, effectively reducing material handling time and energy costs.

Automation and efficiency are key advantages of Liming's equipment. The control system automatically adjusts grinding pressure and airflow, maintaining stable output even under variable feed conditions. Built-in dust collection and noise reduction designs also ensure environmentally friendly and safe production.

With decades of experience and installations across Asia, Europe, and Africa, Liming Heavy Industry has become a trusted supplier of complete kaolin processing solutions. Its advanced grinding technology helps manufacturers achieve higher brightness, better dispersion, and lower production costs—ensuring superior performance in both calcined clay and paper coating industries.
