Precipitated Calcium Carbonate Plant

Customizable Capacity Wide Product Application EPC Project

What is the precipitated calcium carbonate? Precipitated calcium carbonate (PCC) is a calcium carbonate powder produced through chemical processing. It is white and odorless, with an average particle size of only 2–3 μm, a whiteness of 92%–95%, and high purity. Its sedimentation volume (2.4–2.8 mL/g) is greater than that of ground calcium carbonate (GCC) (1.1–1.9 mL/g), which is produced through mechanical grinding. It is a widely used inorganic filler in industrial applications.

AGICO has extensive experience in offering precipitated calcium carbonate plants (PCC plants) with customized output. We provide turnkey solutions covering equipment manufacturing, installation, commissioning, and after-sales service, delivering customized solutions that are cost-effective, intelligent, and energy-efficient to meet each customer’s specific requirements.

Why Choose To Build A Precipitated Calcium Carbonate Plant?

Large market demand: The global market for calcium carbonate reached approximately USD 21.35 billion in revenue in 2025 and is projected to grow to nearly USD 24.75 billion by 2032. A single Tesla Model 3 can consume up to 7.2 kg of precipitated calcium carbonate in its manufacturing process. Cost-effective: Precipitated calcium carbonate is primarily produced from natural limestone, making it significantly less expensive than chemical raw materials such as resins and titanium dioxide. It is an important option for downstream manufacturers seeking to reduce costs. For example, adding 30% calcium carbonate to plastic products can reduce production costs by as much as 22%. Environmentally friendly: Government support for sustainable materials is driving the industry’s growth. As a green mineral material, precipitated calcium carbonate is achieving increasing market penetration. In addition, some manufacturers have implemented tailings recycling systems, raising resource utilization rates to as high as 98% and further enhancing the sustainability of their projects.

Precipitated Calcium Carbonate Manufacturing Process

Step 1: Calcination: Limestone and fuel (such as coal) are fed into a rotary kiln or shaft kiln, where they are calcined at a high temperature of approximately 900–1,100°C to decompose the limestone into quicklime and carbon dioxide.

Step 2: Slaking: Quicklime is thoroughly mixed and reacted with water in a slaker to produce lime milk. The slaker is typically equipped with agitation and heat-retention functions to ensure the reaction is complete.

Step 3: Carbonation: The CO₂ generated during calcination is introduced into the lime milk, where it reacts to form calcium carbonate and water. Reaction conditions, such as temperature, concentration, and agitation speed, can be controlled to regulate the crystal structure and particle size of the calcium carbonate.

Step 4: Separation, Drying, Grinding, Packaging: After the carbonation, the slurry is dewatered, filtered, and washed to remove water and soluble impurities. It is then sent to a dryer for drying. The dried calcium carbonate may contain some agglomerates, so it is ground and sieved to obtain a final product with a uniform particle size before being packaged.

Highlights Of AGICO Precipitated Calcium Carbonate Plant

AGICO delivers more than just equipment. We provide complete solutions, from raw material analysis to the final product. From process design and equipment selection to installation, commissioning, and operator training, we offer comprehensive turnkey project services to ensure your plant is up and running quickly and efficiently.

By optimizing the design and operating parameters of the carbonation system, we can customize products with specific crystal morphologies, such as cubic, spindle-shaped, and needle-like crystals, to meet the diverse requirements of downstream industries, including paper, plastics, and rubber manufacturing, helping you enter higher value-added markets.

Our solution integrates environmental sustainability into every stage of the production process. From the high-efficiency dust collection system used in the lime slaking stage to the water recycling system for process water, our process design minimizes dust emissions and water waste to the greatest extent possible.

Our carbonation system significantly improves carbon dioxide utilization efficiency and shortens the reaction time, thereby reducing electricity and steam consumption. In addition, our continuous dryer and vertical mill are designed to minimize thermal and electrical energy consumption per unit of product, helping you reduce long-term operating and energy costs.
