Calcium Carbonate (CaCO₃) Plant

Production Line Basic Information

We deliver full‑turnkey Calcium Carbonate (CaCO₃) production plant and complete set of calcium‑salt chemical production equipment for global chemical and mineral processing investors. Our production line supports both ground calcium carbonate (GCC) and precipitated calcium carbonate (PCC).

For precipitated calcium carbonate, the process adopts calcination, digestion, carbonation synthesis, filtration, drying, crushing and screening workflow. For ground calcium carbonate, it covers raw ore crushing, grinding, classification and surface modification unit. Equipped with PLC automatic control system, dust‑removal system and waste‑gas treatment facilities, the whole line realizes continuous stable production. We support customized capacity, and can produce industrial‑grade, coating‑grade, plastic‑grade and paper‑grade calcium carbonate with stable particle size and high whiteness to satisfy international market standards.

Core Production Advantages

• Stable product performance: Optimized carbonation and grading technology, precise particle‑size control, high whiteness, low impurity content, good dispersibility for downstream processing.
• High raw‑material utilization: Closed‑loop circulation process reduces material loss and residue discharge, improves comprehensive yield and cuts long‑term plant operating cost.
• Full‑automatic PLC intelligent control: Real‑time monitoring of temperature, pressure, feeding volume and classification parameters, lowers manual labor and supports long‑time continuous running.
• Multi‑product flexible production: Adjust process parameters to produce PCC precipitated calcium carbonate and GCC ground calcium carbonate; surface modification unit is optional for coated calcium carbonate.
• Environment‑friendly production: Complete dust collection and waste‑gas treatment system, low emission, meets global environmental‑protection requirements.
• Reliable anti‑wear & anti‑corrosion structure: Core grinding, calcination and reaction units adopt special wear‑resistant materials, long service life and low maintenance workload.

Main Applications of Calcium Carbonate (CaCO₃)

Calcium carbonate manufactured from our turnkey plant is widely used in multiple industries:

• Paper industry: High‑quality filler and coating pigment, improve paper whiteness, smoothness and reduce production cost.
• Plastic & rubber industry: Functional filler, enhance rigidity, wear resistance and dimensional stability of plastic and rubber products.
• Coating & paint industry: Filler for water‑based and solvent‑based paint, improve coating hiding power and weather resistance.
• Building material & adhesive industry: Raw material for putty, mortar, sealant and building composite materials.
• Chemical & daily‑chemical industry: Filler for detergent, cosmetic raw material and auxiliary agent for chemical processing.
• Food & pharmaceutical industry: Food‑grade calcium carbonate used as calcium supplement and pharmaceutical excipient.
