Heavy calcium carbonate, referred to Ground Calcium Carbonate, is made by grinding natural carbonate minerals such as calcite, marble, limestone. The shape of heavy calcium carbonate is irregular, the particle size difference is large, and the particles have a certain edge, the surface is rough, the particle size distribution is wide, the particle size is large, the average particle size is generally 1~10μm.
Heavy calcium carbonate, also known as ground calcium carbonate, is a common inorganic compound with calcium carbonate (CaCO3) as its main component. The following is a detailed introduction to heavy calcium carbonate:
Physical properties: It is a white powder that is odorless and tasteless. It has a relatively high density, usually between 2.7 and 2.9 g/cm3. It is insoluble in water and ethanol and is stable in the air. Its particle shape is diverse, depending on the processing method. Generally, there are spherical, cubic, flake - like shapes, etc. The particle size can be processed according to different application requirements, ranging from a few microns to tens of microns.
Chemical properties: It is chemically stable under normal temperature and pressure, but it will decompose into calcium oxide and carbon dioxide at high temperatures. It can react with acids to form corresponding calcium salts and carbon dioxide. For example, it reacts with hydrochloric acid to form calcium chloride, water, and carbon dioxide.
Dry process: Natural calcium carbonate ores (such as calcite, marble, etc.) are made into heavy calcium carbonate products of different fineness through crushing and grinding processes. First, the raw ore is initially crushed by coarse - crushing equipment such as jaw crushers, and then it enters grinding equipment such as Raymond mills for grinding. Finally, products of different particle sizes are obtained through classification equipment. The dry process is simple and has a low cost, but the fineness and surface properties of the products are relatively poor.
Wet process: After the ore is crushed, water and dispersants are added for wet grinding to obtain a calcium carbonate slurry, and then the product is made through filtration, drying, and other processes. The wet process can obtain finer products with better surface properties, but the production process is more complex and the cost is higher.
Plastic industry: As a filler, it can improve the hardness, rigidity, heat resistance, and dimensional stability of plastic products and reduce costs. At the same time, it can also improve the processing performance of plastics, such as improving fluidity and demoulding properties.
Rubber industry: It is used in rubber products to increase the volume of rubber, reduce costs, and improve the hardness, wear resistance, and tear resistance of rubber.
Coating industry: It is an important filler in coatings, which can improve the hiding power, gloss, weather resistance, and stability of coatings. In latex paints, it can improve the whiteness and texture of coatings.
Paper industry: As described in detail before, as a filler and coating pigment, it can improve the opacity, whiteness, smoothness, and other properties of paper and reduce costs.
Ink industry: It is used in inks to adjust the viscosity, fluidity, and drying properties of inks, improve the hiding power and gloss of inks, and make printed products more vivid and clear in color.

Our Advantages
We have our own mine in Hubei Province, which endows us with the following advantages:
Stable Raw Material Supply: Owning our own mine ensures a stable supply of raw materials for calcified substances. This helps to avoid production interruptions caused by issues such as fluctuations in the raw material market and supply shortages. It guarantees the smooth progress of production plans and maintains a stable product output, enabling us to better meet customer needs and enhance customer satisfaction.
Controllable Raw Material Quality: Our company can directly manage and monitor the mining process of the mine, and strictly control the quality of raw materials. We are able to select appropriate ore grades and qualities according to production requirements, ensuring that the mined ore meets the high standards of our products. This provides a solid foundation for producing high-quality calcified substance products and helps to enhance the market competitiveness of our products.
Cost Advantage: Obtaining raw materials from our own mine reduces intermediate procurement links and lowers procurement costs. Moreover, in the long run, a stable raw material supply also enables our company to take the initiative in cost control and avoid the risk of cost increases due to fluctuations in raw material prices, thereby improving the company's economic benefits and profitability.
