Calcite and limestone are the two primary raw materials for producing ground calcium carbonate (GCC). While both contain calcium carbonate, calcite offers higher purity, whiteness, and consistency, making it ideal for plastics, coatings, paper, and other high-value applications.

Low-load operation is a normal condition in modern lime rotary kilns. By prioritizing kiln speed, maintaining fuel-air balance, optimizing draft control, and adopting predictive thermal management, producers can prevent ring formation, maintain high lime reactivity, stabilize emissions, and achieve efficient, reliable kiln performance even at 60–85% of rated capacity.

Liming Heavy Industry will participate in EXPONOR Chile 2026 at Booth 408, showcasing advanced grinding mills, mineral processing solutions, and EPC services for mining, cement, and industrial mineral projects across South America.

Liming Heavy Industry signed a strategic partnership with a leading Bulgarian mining and energy group, expanding its presence in Southeast Europe through localized grinding solutions, EPC services, and advanced mineral processing technologies.

In actual production, excessive oxygen levels caused by air leakage, unstable airflow, or improper combustion management can significantly amplify corrected NOx and SO₂ values, even when measured emissions appear acceptable.

Plastic masterbatch is a key material in modern plastics processing, enabling efficient coloring, filling, reinforcement, and functional modification for packaging, automotive, construction, cable, and high-performance polymer applications worldwide.

Calcium carbonate is transforming from a traditional industrial mineral into a key material for batteries, improving safety, recycling, thermal management, and energy storage performance.

After more than two decades in the mineral grinding and powder processing industry, one of the most regrettable realities I have witnessed is seeing high-quality calcium carbonate ore reduced to low-value commodity powder sold for only a few hundred dollars per ton. For years, because of its natural

Calcium carbonate is rapidly evolving from a low-cost filler into a high-performance functional material widely used in superhydrophobic coatings, construction protection, advanced textiles, marine engineering, and sustainable industrial applications worldwide.

This article analyzes the limitations of traditional lime kiln intelligent systems and introduces a next-generation expert system integrating process expertise, self-learning, and dynamic balance control for global lime industry applications.

This article analyzes the catalyst deactivation mechanism in medium-temperature and dust-laden SCR denitration systems for cement clinker production lines and introduces an in-situ thermal desorption regeneration solution using high-temperature flue gas.

Today, surface-modified calcium carbonate is no longer viewed as a simple filler. It has become an important functional material for improving product performance, optimizing processing efficiency, and supporting sustainable material development.
