CLIRIK offers a comprehensive range of limestone crushing and grinding systems. Our technology is designed to optimize your production efficiency, significantly reduce specific energy consumption, and meet the most stringent manufacturing requirements for various limestone-based products.

Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO₃). It is formed through the accumulation of marine organisms and chemical precipitation over millions of years, resulting in a unique micro-crystalline or clastic structure. Its high chemical purity and consistent CaO content make it an exceptional precursor for fine industrial powders.

With a Mohs hardness of 3, limestone is relatively easy to pulverize while maintaining a high degree of particle uniformity. It is naturally available in colors ranging from pure white to gray. Once processed into ultra-fine powder, it exhibits high brightness, excellent weather resistance, and a low oil absorption value. These inherent properties ensure its seamless integration into various resin systems, providing essential structural reinforcement and improved surface quality for the final products.

Ground Calcium Carbonate (GCC) is produced by the mechanical pulverization of natural minerals like limestone or marble. Since it involves no chemical transformation, it retains the mineral’s original stability but features an irregular, fragmented structure.

Key Properties: High density, low oil absorption, and excellent flowability.

Industrial Value: Used as a “functional filler” in plastics, rubber, and coatings. It increases volume and hardness while allowing high loading levels to significantly reduce production costs.

Precipitated Calcium Carbonate (PCC), or light calcium carbonate, is a synthetic compound produced through a chemical carbonation process. By calcining limestone and reacting it with CO₂, manufacturers can precisely control the particle morphology to create specific shapes like spindles, spheres, or needles.

Key Properties: Ultra-high whiteness, narrow particle size distribution, and high sedimentation volume.

Industrial Value: Its microporous structure and large specific surface area make it ideal for high-end paper, specialized paints, and pharmaceuticals requiring reinforcement and superior brightness.
