Our Product

Background Image

Red Clay

Red Clay Powder is a finely processed natural mineral material derived from iron-rich clay deposits. Its distinctive red coloration is primarily attributed to high concentrations of iron oxide (Fe₂O₃), which also contributes to its chemical stability and durability. The material is mechanically processed through drying, crushing, grinding, and sieving to achieve uniform particle size distribution suitable for industrial and commercial applications.

White Clay

White Clay Powder is a finely processed natural mineral derived from high-purity kaolin clay deposits. Its white to off-white color is due to the very low iron content, resulting in a clean and stable composition. The material is processed through drying, crushing, grinding, and sieving to produce a consistent particle size distribution suitable for industrial use. It is commonly used in ceramics, paper coating, paints, rubber, and cosmetics due to its fine texture, chemical stability, and mild absorbent properties.

Limestone

Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO₃) in the form of the mineral calcite. With a high CaCO₃ content, this product is classified as high-grade limestone, making it highly suitable for heavy industrial applications such as cement manufacturing, steelmaking flux, production of quicklime, and as a filler in the chemical, paper, and paint industries. Its consistent composition, excellent purity, and reliable physical properties ensure stable performance across demanding processes, supporting efficiency and quality in large-scale industrial operations.

Silica Sand

Silica Sand is a granular material composed primarily of silicon dioxide (SiO₂), derived from high-quality natural quartz deposits. With a purity level of SiO₂ reaching 99.5%, this product is classified as high-purity silica sand, making it highly suitable for demanding industrial applications such as glass manufacturing, foundry casting, and chemical processing. Its uniform particle size distribution, low impurity content, and excellent chemical stability ensure consistent performance, supporting efficiency and high-quality output across various industrial processes.

Dolomite

Dolomite Powder is a finely ground natural mineral composed primarily of calcium magnesium carbonate (CaMg(CO₃)₂). It is widely used in agriculture, construction, metallurgy, water treatment, and various industrial applications due to its high neutralizing value and well-balanced calcium–magnesium content. Its consistent quality, fine particle size, and chemical stability enhance its effectiveness in improving soil conditions, strengthening construction materials, and supporting efficient industrial processes. These characteristics make dolomite powder a reliable and versatile solution for a wide range of commercial and industrial needs.
