From Ore to Quality Crafting: Liming Grinding Mills Propel the GCC Industry to a New Level

Ground Calcium Carbonate (GCC) is a powdered material processed and produced from raw materials such as calcite, marble, limestone, dolomite, chalk and shells via milling equipment. As an excellent filler, GCC features high whiteness, easy colorability and stable chemical properties. With its notable cost advantages, stable and controllable components, and strong functional adaptability, it is widely used in various scenarios of production and daily life. From commonly used tissues and cartons to coatings required for house decoration, GCC plays an indispensable role in a diverse range of industries.

Applications of GCC Powder

Known as the "cornerstone material" of industrial production, GCC powder demonstrates its dominant strength in four key sectors: papermaking, coatings, rubber and plastics. It acts as an invisible driver for various industries to solve challenges related to cost, performance and efficiency.

Beyond these sectors, GCC powder is also widely used in non-woven fabrics, silicone sealants, construction and other industries. From daily necessities to engineering construction, it is ubiquitous and underpins the quality upgrading of diverse industries.

Grinding as the Key to Unlocking the Quality Code of GCC Powder

As a material widely used in various industrial sectors, GCC’s performance is determined by several key technical indicators, which directly influence the application performance of ultra-fine calcium carbonate.

From natural ore to industrial filler meeting industry standards, GCC powder undergoes four core processes: mining, crushing, grinding and collection. Grinding is the critical link that converts the advantages of GCC powder into practical application value. Only by precisely controlling the grinding process can GCC powder be applied in a tailor-made manner across different sectors, embodying its core value as a fundamental industrial material.

The precise implementation of the grinding process cannot be achieved without professional grinding equipment with strong adaptability and stable performance. Based on nearly 40 years of R&D experience in grinding machines, Liming Heavy Industry deeply integrates process logic with equipment innovation. The GCC powder produced by its series of grinding machines boasts high whiteness, uniform particle size distribution, high activation degree and low impurity content. It covers the production scenarios of finished powder with different fineness levels, meeting all types of demands of manufacturing enterprises in their diversified development and full industrial chain layout.
