Calcium Carbonate Limestone Processing Solutions
Calcium carbonate (CaCO₃) is an important inorganic compound widely found in nature, commonly known as limestone or stone powder. It mainly originates from ores such as calcite, marble, and limestone. It is a major component of animal bones and shells and is also one of the most widely used inorganic fillers in industry.
Encompassing both ground (GCC) and precipitated (PCC) forms, CaCO₃ is prized for its high whiteness and chemical stability. By utilizing our CLIRIK CLG series and its unique triangular structure, we achieve a coating ratio above 98%. This advanced technology maximizes the material’s compatibility with polymer resins, effectively increasing filler loading for you while significantly reducing raw material costs without sacrificing mechanical strength.

Process & Solutions
The definitive answer to the aforementioned industry challenges lies in our refined and systematic industrial processing. The industrial processing of calcium carbonate follows a meticulous workflow, aiming to transform natural ore into high-value-added functional powder materials.
Our comprehensive production solution covers six core stages: crushing, grinding, classifying, powder collection, modification (selective formulation), and packaging, ensuring every production hurdle is seamlessly overcome.

Stage 1:Crushing
Large pieces of calcium carbonate raw materials (such as calcite and limestone) are first coarsely crushed by a jaw crusher to control their particle size within the range of 15mm-50mm, so as to meet the feeding requirements of subsequent grinding equipment.
Stage 2:Grinding
The crushed small pieces of material are fed into the raw material silo by an elevator, and then fed into the grinding chamber of the mill by a vibrating feeder in a uniform and quantitative manner.
● Ultrafine Powder Processing: For the demand for high-end fine powders of 200-2500 mesh and above, we recommend the HGM Series Ultrafine Mill. The HGM Series Ultrafine Mill, with its multi-layer grinding ring and suspension roller design, combined with a high-precision classifier, can stably produce ultrafine powders of 2500 mesh (D97≤5μm).
● Conventional fine powder processing: For ordinary fillers of 80-325 mesh, we recommend CLRM Raymond Mill, which has a uniform particle size distribution and high sieve pass rate, making it a classic choice with excellent cost performance.
● High-end ultrafine powder processing: For high-end fillers with stringent requirements for powder particle shape and whiteness, we strongly recommend the CLUM Series Ultrafine Vertical Mill. This equipment utilizes a bed grinding principle, producing spherical powder particles with excellent flowability and high bulk density.
Simultaneously,its unique grinding structure prevents metal wear, maximizing the preservation of the material’s original whiteness and significantly enhancing the grade and performance of downstream products.
Stage 3:Classifying
The ground material is carried by airflow into a high-efficiency classifier for grading. Our equipment is equipped with a variable frequency speed-controlled impeller classifier, which can easily achieve precise cutting of different mesh sizes (such as 325 mesh, 600 mesh, 1250 mesh, 2500 mesh, and 3000 mesh) by precisely adjusting the speed.
Unqualified coarse particles are separated and returned to the main unit for regrinding, forming a closed-loop cycle to ensure uniform particle size distribution and the absence of oversized particles.
Stage 4:Powder Collecting
Fine powder meeting the required particle size is carried by airflow into a pulse dust collector for gas-solid separation. The entire system operates under negative pressure and is equipped with a long-bag low-pressure pulse dust collector, resulting in dust emission concentrations far below national standards and a collection efficiency of up to 99.9%.
The collected finished powder is then conveyed to the finished product silo via a screw conveyor or pneumatic conveying system through the discharge port.
Stage 5:Modification (Optional)
For high-end applications (such as plastic and rubber reinforcement), a continuous powder surface modification machine can be selected.
By mixing at high speed at a certain temperature and spraying in modifiers such as stearic acid and titanate, the surface of calcium carbonate is activated, improving its dispersibility, hydrophobicity, and compatibility with organic matrices, thereby significantly improving the performance of downstream products.
Stage 6:Packaging
The final product is packaged according to customer requirements. Typically, automatic baling machines are used for 25kg/bag packaging, or ton bags are used for bulk packaging. For bulk transportation needs, powder tank trucks can also be used for direct loading. A dust removal system is provided throughout the process to ensure environmental cleanliness.
