Calcium Carbonate Powder Production Line

Calcium carbonate powder production line includes several machines such as crushers, dryers, grinding mills, classifiers, coating machines, and packing machines. Each stage of the production process requires specific equipment to facilitate the calcium carbonate powder production.

It is important to note that the specific machines and equipment used in a calcium carbonate powder production line may vary depending on the production capacity, desired particle size, and other factors. Additionally, the production line may also include additional stages or equipment to meet specific requirements.

Calcium carbonate manufacturing process

  • 1. Crushing Stage: The calcium carbonate raw material is crushed by primary and secondary crushers to reduce the size of the stones. Jaw crushers or impact crushers are commonly used for this stage.
  • 2. Grinding Stage: The dried calcium carbonate material is then ground into a fine powder using grinding mills. Ball mills, Raymond mills, or vertical roller mills are commonly used for grinding.
  • 3. Classification Stage: The ground calcium carbonate powder is classified into different particle sizes using classifiers. Air classifiers or vibrating screens are commonly used for this stage.
  • 4. Coating Stage: Some applications require the calcium carbonate powder to be coated with a surface modifier to improve its properties. Coating machines are used to apply a coating material onto the powder particles.
  • 5. Packing Stage: The final step is to pack the calcium carbonate powder into bags or containers for transportation and storage. Packing machines are used to fill and seal the bags or containers.

What is calcium carbonate?

Calcium carbonate(CaCO₃) is a chemical compound widely found in natural inorganic compounds such as limestone, chalk, calcite and marble. Due to its unique properties, such as its white color, calcium carbonate powder is widely used in various industries as a filler or coating pigment.

Calcium carbonate can generate quicklime through heating, while quicklime can react with water to produce hydrated lime. All these three materials have a wide range of applications in paper, glass, construction and other industries. So, it is of great economic value to build a calcium carbonate processing plant.

However, the calcium carbonate manufacturing plant consists of a complete set of machinery that needs professional design and engineering. Henan Daswell Machinery is your preferred partner, with rich experience in calcium carbonate plant project design and engineering. Besides, Daswell offers a complete set of quality equipment relevant to the ground calcium carbonate plant.

Application of calcium carbonate powder

Due to its unique properties, ground calcium carbonate powder can be used in many areas. For example, calcium carbonate powder is usually applied in paper, construction, paint, plastic, glass and other industries such as filler, adhesives, etc. For instance, in the paper industry, calcium carbonate is often used as an inexpensive filler to brighten opaque paper due to its high brightness and light-scattering characteristics.

Of course, different usages have different requirements for the finished calcium carbonate powder, while high-quality calcium carbonate with excellent whiteness has greater economic value. Several factors can affect the quality, fineness, whiteness and surface of the calcium carbonate powder.

One is the quality and properties of raw materials to be processed. Another critical factor is the grinding system, a wet or dry grinding mill, which can impact the whiteness and fineness of the end product. In line with your needs, Daswell will provide tailored turnkey solutions for your calcium carbonate manufacturing process while considering costs.
