Introduction
Guangxi Hezhou Kelong Micro-powder Co., Ltd. is a Chinese non-metallic mineral and calcium carbonate producer founded in 1997 and based in Pinggui District, Hezhou, Guangxi. The company integrates mining, ultrafine powder processing, new material research and development, sales, and service, and is primarily known for producing heavy calcium carbonate and related surface-treated powder materials used in plastics, rubber, paper, coatings, inks, artificial stone, construction materials, and daily chemical products.
In the plastics industry, Kelong functions as a filler and functional powder supplier rather than a polymer resin producer. Its products are relevant to plastic compounding, cost reduction, stiffness modification, and processing performance, especially in applications requiring controlled particle size and surface treatment. The company has been described in industry listings as a national high-tech enterprise and one of China’s important heavy calcium carbonate producers, with participation in standards work and a long operating history in calcium carbonate processing.
History and Development
Kelong was established in 1997, beginning as a mineral processing enterprise focused on calcium carbonate resources in Hezhou, a region long associated with non-metallic mineral extraction and powder processing.
A major development in the company’s evolution was the expansion from basic mineral processing into ultrafine powder and surface modification, supported by milling and classification technologies such as ball mills, vertical mills, ring-roller mills, and continuous surface treatment equipment.
The company also broadened its industrial standing through standards participation and technology recognition. Public sources state that it contributed to the formulation of national and industry standards related to calcium carbonate and has been recognized as a high-tech enterprise and an engineering technology research center in Guangxi.
Business Operations and Segments
Kelong’s business model centers on an integrated chain that includes:
- Mineral resource extraction
- Raw material preparation and crushing
- Ultrafine grinding and classification
- Surface treatment / coating modification
- Sales and technical service
The company’s industrial base is located in Kelong Industrial Park in Hezhou, where it operates a large production site and mineral resource base. Public descriptions vary on scale, but sources consistently indicate that Kelong operates multiple production lines and a substantial annual output capacity for heavy calcium carbonate products.
Its business is closely tied to the calcium carbonate value chain, supplying powders for downstream processors in plastics, coatings, paper, and building materials.
Products and Technologies
Kelong’s product portfolio is centered on heavy calcium carbonate, including both ordinary and surface-treated / modified grades.
Common product categories referenced in public sources include:
- Heavy calcium carbonate
- Ultrafine calcium carbonate
- Surface-treated calcium carbonate
- Industrial ground calcium carbonate
- Transparent filling materials
- Talk / French chalk products
Technical features cited in company descriptions include:
- Closed-circuit ball mill and classification grinding
- Vertical mill and ring-roller mill processing
- Continuous surface treatment equipment
- Automatic and enclosed production systems designed to reduce dust and improve consistency
These process capabilities matter for plastics because particle size distribution, whiteness, moisture control, and surface compatibility can influence dispersion, tensile and flexural reinforcement, melt behavior, and surface finish in filled polymer compounds. That relevance is implied by the company’s focus on plastic applications and surface-treated calcium carbonate grades.
Applications and End Markets
Kelong’s products are used in several industrial sectors, with plastics being one of the major end markets.
| End market | Typical role of calcium carbonate products |
|---|---|
| Plastics | Filler, cost reduction, stiffness modification, processability support |
| Rubber | Reinforcement and formulation filler |
| Paper | Extender and brightness-related filler |
| Coatings and inks | Extender, rheology and opacity support |
| Artificial stone / building materials | Mineral filler and formulation component |
| Daily chemicals | Functional powder ingredient in selected formulations |
The company’s product descriptions also mention transparent filling materials, indicating use in polymer systems where optical performance and fine particle control are important.
Global Presence and Market Position
Kelong is positioned as a regional Chinese producer with national industry relevance in heavy calcium carbonate, rather than as a diversified multinational chemical group.
Its sales network has been described as extending beyond Guangxi to offices or sales points in Shanghai, Qingdao, Linyi, Quanzhou, Guangzhou, Shunde, Nanhai, Shenzhen, Dongguan, Guilin, and Hezhou, suggesting a distributed domestic marketing structure aimed at serving major industrial clusters in eastern and southern China.
Industry and exhibition listings identify the company as a participant in CHINAPLAS-related specialized enterprise programs, which reflects its visibility within the plastics and rubber supply chain.
Sustainability and Environmental Initiatives
Public materials indicate that Kelong has pursued environmental management and cleaner production practices, including the use of enclosed, automated processing systems that can reduce dust and intermediate contamination.
The company has also been associated with ISO 14001 environmental management certification in older public descriptions, alongside quality management and industrial compliance references. Because these claims appear in secondary company profiles rather than recent audited disclosures, they should be treated as evidence of stated management systems rather than independently verified current certification status.
For calcium carbonate producers, sustainability considerations generally include resource efficiency, quarry management, dust control, energy use in grinding operations, and product substitution effects in downstream plastics formulations. Kelong’s business model sits squarely within these sector-wide issues.
Financial Performance and Economic Impact
No recent audited financial statements were included in the available sources. However, public business records indicate that Kelong has a registered capital of 138 million yuan and maintains a significant industrial footprint in Hezhou.
The company contributes to the local economy through:
- Mining and industrial employment
- Industrial park-based manufacturing
- Local tax contribution
- Supply to multiple downstream sectors
It has also been described in industry profiles as an established enterprise with long-term manufacturing and taxpayer recognition in Hezhou’s Pinggui District.
Leadership and Corporate Governance
Public business records identify Li Qihong as the legal representative and executive leadership figure associated with the company. Other contact and sales listings reference company personnel involved in commercial operations, but no full governance structure was disclosed in the supplied sources.
The company is organized as a privately held enterprise under Chinese corporate registration, with operations spanning mining, manufacturing, and trade-related functions.
Innovation and Industry Participation
Kelong’s innovation profile is linked to ultrafine grinding, powder classification, surface modification, and mineral processing optimization.
Notable indicators of technical participation include:
- Contribution to national and industrial standards related to calcium carbonate analysis and industrial ground calcium carbonate.
- Recognition as a high-tech enterprise and a specialized industrial participant in calcium carbonate processing.
- A portfolio of patents and administrative approvals reported in third-party business intelligence listings.
These activities suggest an emphasis on process control and product consistency, both of which are important in plastic compounding where filler performance depends on particle engineering rather than only on chemical composition.
Outlook
Kelong’s future prospects are likely to remain tied to demand in plastics, coatings, building materials, and paper, with continued emphasis on fine-particle calcium carbonate grades and surface-treated formulations.
The company’s strategic relevance in the plastics sector will depend on its ability to:
- Maintain consistent particle engineering
- Improve surface treatment and dispersion performance
- Support downstream customers with application-specific grades
- Adapt to stricter expectations on dust control, energy efficiency, and resource utilization
