Ultrafine Air Classifier

In the process of upgrading the calcium carbonate industry toward high-end development, purity and impurity control capabilities serve as the core technical thresholds. These capabilities differentiate product grades and determine application boundaries. General industrial-grade calcium carbonate only needs to meet basic filling requirements. It also maintains a higher tolerance for trace impurities. In contrast, high-purity […]

Calcium carbonate, as the most abundant and lowest-cost inorganic powder filler, naturally exhibits strong hydrophilicity on its surface. However, it has poor compatibility with organic polymer matrices such as plastics, rubber, and coatings. Under high loading conditions, it tends to suffer from particle agglomeration, weak interfacial bonding, and reduced mechanical properties of final products. These

Calcium Carbonate Filler for Plastics (including both ground calcium carbonate and precipitated calcium carbonate) is currently the most widely used and highest-volume inorganic filler in the plastics industry. It is not merely a “supporting-role” filler, but rather a “performance modifier” that fine-tunes the properties of modified plastics. The key functions of calcium carbonate in plastics

In the production of ground calcium carbonate (GCC), grinding equipment is undoubtedly the core of the entire production line. However, many clients who are new to the calcium carbonate processing industry often have a question when selecting equipment. Since there is already a mill, why is it necessary to additionally equip it with an air

EPIC Powder sincerely invites you to attend CIBF2026. Please visit us at Booth 12T135 from May 13–15, 2026.

Together, we will gather at this

As global “plastic bans” gain momentum, biodegradable plastics represented by PLA (Polylactic Acid) and PBAT (Polybutylene adipate terephthalate) have become core materials in fields such as green packaging and ecological agriculture. However, due to challenges like high raw material costs and unstable processing performance, calcium carbonate (CaCO3)—as an abundant, eco-friendly, and low-cost inorganic mineral filler—has

Calcium carbonate is the most widely used and largest-volume inorganic mineral filler. However, its naturally hydrophilic and oleophobic surface characteristics lead to poor compatibility with organic polymer materials such as plastics, rubber, and resins. When added directly, it tends to agglomerate, which seriously affects the processing performance and mechanical properties of downstream products. Surface modification

Calcium carbonate is one of the most widely used inorganic mineral powders in the world. It is extensively applied in industries such as plastics, rubber, coatings, paper, adhesives, sealants, and building materials. In many of these applications, particle size plays a critical role in determining the final product performance. Ultrafine calcium carbonate with controlled particle

If you’re tackling the challenge of aragonite ultrafine grinding, you already know it’s not just about pulverizing calcium carbonate. Preserving that distinctive needle-like crystal structure while achieving a tight particle size distribution demands more than standard milling. In industrial mineral processing, the right combination of machinery and technique can make or break product performance—especially in
