Calcium carbonate (CaCO₃) plays a crucial role in various industrial applications, especially in the rubber manufacturing sector, where it serves as an essential filler material. The global demand for calcium carbonate is steadily rising due to its extensive use in the production of plastics, paints, sealants, and particularly rubber goods. In Nigeria, with its expanding manufacturing base and developments in the rubber industry, the demand for high-quality calcium carbonate filler has been growing fast. Selecting the right grinding mill for producing calcium carbonate powder with high purity, uniform fineness, and stable production is key to improving product quality and competitiveness.
Shanghai Zenith Machinery Co., Ltd., a leading Chinese manufacturer of ore grinding equipment, provides advanced solutions for calcium carbonate grinding and processing. With decades of experience and continuous technological innovation, Zenith has developed a complete range of grinding mills suitable for different production capacities and fineness requirements. For a calcium carbonate grinding project targeting 5–10 tons per hour (TPH) in Nigeria, Zenith offers several professional options optimized for energy efficiency and performance.
Calcium carbonate acts as a cost-effective filler in the rubber industry, enhancing the physical properties of rubber materials. It brings multiple benefits, such as improved tensile strength, gloss, and whiteness, and a reduction in production costs. In rubber compounding, finely ground calcium carbonate enables better dispersion, uniformity, and strength, which ultimately improve the durability and appearance of end products such as tires, seals, footwear, and industrial rubber goods.
In Nigeria, the local availability of limestone, which is the primary source of calcium carbonate, makes it feasible to establish localized grinding plants. However, manufacturing high-quality rubber-grade calcium carbonate requires consistent particle size distribution and controlled moisture content. This emphasizes the importance of selecting reliable and efficient grinding equipment.
These technical requirements can be met with modern grinding technologies, particularly vertical roller mills and medium-speed mills, which ensure stable operation, precise fineness control, and high output efficiency.
To achieve a production rate of 5–10 TPH, two suitable grinding systems are highly recommended from Shanghai Zenith Machinery Co., Ltd.: the MTW Trapezium Grinding Mill and the MTM Medium-Speed Grinding Mill. Both models are designed with patented technologies, energy-saving concepts, and ease of maintenance, making them ideal choices for calcium carbonate processing in Nigeria.
The MTW Trapezium Grinding Mill is one of Zenith’s flagship products, integrating advanced European technology. It’s particularly effective in producing fine and uniform powder suitable for industrial fillers such as calcium carbonate for rubber and plastic industries. Its design features high-efficiency fans, unique curved blade arrangements, and improved dust sealing systems.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW110 | <30 | 1.6–0.045 | 3–9 | 55 | 55 |
| MTW110Z | <30 | 1.6–0.045 | 3–10 | 55 | 55 |
| MTW138Z | <35 | 1.6–0.045 | 6–17 | 90 | 110 |
For a Nigerian plant targeting 5–10 TPH production, the MTW110Z or MTW138Z models are ideal. They provide high grinding efficiency, automatic control systems, and reliable performance under tropical environmental conditions. Their modular design also supports easy installation and scaling up in case of production expansion.
The MTM Medium-Speed Grinding Mill is an ideal substitute for traditional Raymond Mills. Its design integrates rolling, grinding, and air separation technologies to ensure a consistent final particle size and stable operation. This model suits medium-hard minerals such as limestone and is perfect for calcium carbonate projects within the 5–10 TPH range.
| Name | Ring Roll Number (pcs) | Max. Feed Size (mm) | Output (t/h) | Main Unit Motor Power (kW) |
|---|---|---|---|---|
| MTM100 | 4 | <25 | 3–8 | 37 |
| MTM130 | 5 | <30 | 6–11 | 75 |
For consistent fine powder with D97 between 75 μm and 45 μm, the MTM130 offers optimal performance for rubber-grade filler production. Its durable rolling structure reduces maintenance needs and increases productivity, which is critical for Nigerian operations aiming to minimize downtime and operational costs.
Shanghai Zenith Machinery’s equipment integrates intelligent control systems, ensuring optimal performance, stability, and operator-friendly functionality. Below are the key advantages offered by these mills:
When planning a calcium carbonate processing line in Nigeria, it’s essential to consider both the raw material characteristics and local environmental conditions. Zenith’s engineering team can offer complete EPC (Engineering, Procurement, and Construction) solutions that include plant design, equipment layout, and installation guidance.
With scalable solutions and reliable after-sales service, Zenith ensures every Nigerian client can achieve sustainable and profitable production of calcium carbonate filler for rubber manufacturing.
Producing high-quality calcium carbonate for rubber filler applications requires a reliable and precise grinding system. In Nigeria, where demand for rubber and industrial fillers continues to grow, partnering with an experienced equipment manufacturer is vital. Shanghai Zenith Machinery Co., Ltd. provides world-class solutions through its MTW Trapezium Grinding Mill and MTM Medium-Speed Grinding Mill—both designed to deliver high efficiency, precise fineness control, and energy-saving performance.
