CALCIUM CARBONATE GRANULAR

Calcium Carbonate Granular is a high-quality material produced from carefully selected natural limestone sources in Vietnam. The limestone is mined, cleaned, crushed, and processed through modern machinery to achieve precise granule sizes with exceptional purity and whiteness. Each granule contains a high percentage of calcium carbonate (CaCO₃) and is free from harmful impurities, ensuring reliable performance in various applications.

The granular form of calcium carbonate offers significant advantages over powder forms in certain industries. Its controlled particle size allows for consistent dissolution rates, making it especially suitable for water treatment, agriculture, and processes where a gradual release of calcium is required. The granules are also easy to store, handle, and transport, with minimal dust generation — improving workplace cleanliness and reducing product loss during application.

Limestone Granular for Feed Grade

Thanks to its high whiteness and chemical stability, calcium carbonate granular is widely used in glass manufacturing as a key ingredient to improve the durability, clarity, and brightness of the final product. In the paint industry, it serves as an excellent extender and filler, enhancing opacity, brightness, and surface smoothness while also reducing production costs without compromising quality.

In agriculture, it provides a stable and effective source of calcium for soil amendment and livestock nutrition. In environmental treatment, its high alkalinity helps neutralize acidic environments and improve water quality.

With our advanced processing facilities and strict quality control, each batch of Calcium Carbonate Granular maintains uniform size, density, and chemical composition, ensuring predictable and consistent results for customers worldwide.

Packaging: Calcium Carbonate Granular is packaged following the customer’s requirements (25kg bag, Customized Jumbo bag, etc.). We also provide wrapping films and strapping belts if needed.
