Non-Metallic Mineral Grinding in Nigeria: HGM Ultrafine Mill for Dolomite & Limestone Processing

13/06/2025 admin

HGM Ultrafine Grinding Mill enhances non-metallic mineral grinding in Nigeria. High output, energy efficiency & 325–3000 mesh precision.

Dolomite Non-Metallic Mineral Grinding in Nigeria

A recent success story from Nigeria’s non-metallic mineral sector demonstrates the rising demand for advanced non-metallic mineral grinding solutions. One of our clients in Nigeria successfully installed the HGM80 ultrafine grinding mill to process dolomite into high-purity powder with a D90 passing size of 40 microns. Operating at a stable output of 3.5 tons per hour, the project showcases the power of HGM technology in delivering precise, efficient, and scalable non-metallic mineral grinding results.

As Nigeria continues to explore the full potential of its abundant non-metallic mineral resources—such as limestone, dolomite, talc, and kaolin—there is a growing need for reliable non-metallic mineral grinding equipment capable of meeting both domestic and export demands. This article explores the distribution of non-metallic minerals in Nigeria, analyzes the market potential, and discusses in detail why the HGM ultrafine grinding mill is the optimal solution for local non-metallic mineral grinding and industrial mineral processing.

——Non-Metallic Mineral Grinding Resources in Nigeria——

Nigeria possesses vast deposits of non-metallic minerals, many of which are underexplored and underutilized. Key resources include:

  1. • Limestone: Abundantly found in Kogi, Edo, Ogun, Cross River, Benue, and Nasarawa states. It is primarily used in cement production but also in steel, construction, and environmental industries.
  2. • Dolomite: Widely distributed in Kogi, Nasarawa, Oyo, Katsina, and Plateau states. Used in ceramics, glass, and metallurgy.
  3. • Kaolin: Found in large quantities in Ogun, Plateau, Katsina, and Bauchi states. A vital ingredient in ceramics, paper, and paint.
  4. • Talc: Mainly located in Niger, Osun, Kogi, and Kaduna states. Used in cosmetics, plastics, and pharmaceuticals.
  5. • Bentonite: Common in Borno and Adamawa states. Essential for drilling muds and iron ore pelletizing.

Despite these resources, the country still imports significant quantities of processed minerals due to a lack of advanced local non-metallic mineral grinding and classification technology.

—Market Analysis of Non-Metallic Mineral Grinding in Nigeria—

With the Nigerian government emphasizing economic diversification and industrialization, the non-metallic mineral grinding sector stands as a key growth area. Several factors drive this opportunity:

  1. • Growing Construction Sector: Demand for limestone-derived cement and other building materials is rapidly rising.
  2. • Agricultural and Pharmaceutical Growth: Increased use of dolomite and talc in fertilizers and drugs.
  3. • Oil and Gas Industry: Bentonite plays a critical role in drilling operations.
  4. • Import Substitution Policy: Government initiatives aim to reduce dependency on imported industrial minerals.
  5. • Export Potential: Finely processed minerals have high export value, especially in West Africa.

However, most local processors use outdated technology, resulting in low productivity, inconsistent fineness, and high energy consumption. This gap presents a prime opportunity for the deployment of modern, efficient non-metallic mineral grinding mills like the HGM series.

——HGM Ultrafine Mill: The Ideal Solution for Non-Metallic Mineral Grinding——

The HGM Ultrafine Grinding Mill, developed by Shanghai CLIRIK Machinery Co., Ltd., is a state-of-the-art solution specifically designed for producing ultrafine powder (325–3000 mesh) from non-metallic mineral materials. It is renowned for its efficiency, versatility, and long-term operational reliability.

Key Features:

  1. • Wide Range of Materials: Processes more than 100 types of non-metallic minerals including limestone, dolomite, calcite, kaolin, talc, barite, gypsum, and bentonite.
  2. • High Fineness: Adjustable output size from 325 mesh (45 µm) up to 3000 mesh (5 µm), with D50 around 5–10 microns depending on the configuration.
  3. • Energy Efficiency: Compared to traditional Raymond mills and ball mills, the HGM consumes 30–40% less energy.
  4. • Large Capacity: Production capacity ranges from 0.5 to 45 tons per hour depending on model and material.
  5. • Intelligent Control: Equipped with PLC control systems for real-time monitoring and adjustment.
  6. • Compact Design: Modular design allows for easier installation and space-saving layout.
Rock Pulverizer Machine HGM Ultrafine Mill

Working Principle: HGM mill consists of a main unit, classifier, dust collector, and blower. Raw materials are fed into the grinding chamber where rollers and grinding rings pulverize them through centrifugal force. Fine particles are classified and collected through the airflow system, while coarse materials are returned for further non-metallic mineral grinding.

——Advantages of HGM Ultrafine Mill in Non-Metallic Mineral Grinding——

  1. • Adapts to Local Raw Materials: HGM is compatible with various Nigerian non-metallic minerals like limestone, dolomite, and talc.
  2. • Improves Product Quality: Achieves precise and consistent fineness, ideal for applications in coatings, plastics, pharmaceuticals, and ceramics.
  3. • Reduces Operational Costs: High grinding efficiency and low energy consumption mean lower production costs.
  4. • Supports Government Policy: Enhances local value addition, aligns with import substitution and job creation policies.
  5. • Scalability: Suitable for small to large-scale operations; modular configuration allows future expansion.

——Successful Applications of HGM in Non-Metallic Mineral Grinding——

Several HGM mills have already been deployed successfully in African countries for similar materials. In one notable case, an HGM125L mill was installed in Nigeria to process limestone into 10-micron powder used in paint manufacturing. The customer reported:

  1. • 3–4 tons/hour capacity
  2. • D50 = 10 microns
  3. • Over 35% cost savings compared to imported powder

This proves the viability of the HGM series for the Nigerian non-metallic mineral grinding context.

——Strategic Investment Tips for Non-Metallic Mineral Grinding in Nigeria——

  1. • Invest in Processing, Not Just Mining: Value is created through refinement. Ultrafine non-metallic mineral grinding increases product worth exponentially.
  2. • Choose Right Equipment: Selecting energy-efficient, high-output mills like HGM ensures profitability.
  3. • Train Local Workforce: CLIRIK provides installation, commissioning, and training support to build local capacity.
  4. • Explore Export Opportunities: With ECOWAS trade agreements, high-purity non-metallic mineral powders can be exported tariff-free to West African neighbors.

Nigeria’s wealth of non-metallic minerals holds immense promise. However, to truly capitalize on this, advanced non-metallic mineral grinding technologies must be adopted. The HGM Ultrafine Grinding Mill offers the perfect combination of precision, efficiency, and adaptability to local conditions. For Nigerian investors, industrialists, and policymakers looking to develop a globally competitive non-metallic mineral grinding sector, the HGM mill is the ideal tool to transform potential into prosperity.
