Basalt, a hard and dense volcanic rock rich in silica and alumina, has increasingly found its way into industrial applications due to its mechanical strength and chemical stability. One of the emerging applications is in the paper-making industry, where finely ground basalt powder serves as a high-performance filler and coating material. Producing basalt powder at a fineness of 325 mesh requires advanced grinding equipment capable of handling abrasive and hard minerals efficiently. In Oman, the demand for such fine basalt powder has grown in line with the expansion of environmentally friendly paper manufacturing processes. This article provides an in-depth analysis of basalt grinding solutions for 325 mesh applications in Oman, focusing on energy-efficient and high-precision milling technologies from Shanghai Zenith Machinery Co., Ltd.
To achieve consistent paper quality, the basalt filler must reach a uniform particle size distribution of 325 mesh (about 44 µm). This ensures smooth paper texture, optimal opacity, and improved ink absorption. Moreover, the grinding process must ensure low contamination levels and maintain the mineral’s natural whiteness and brightness. In Oman’s hot and dry climate, grinding systems also need to consider efficient cooling and dust control to ensure stable production and worker safety.
To overcome these challenges, modern mills must integrate intelligent control systems, wear-resistant materials, and efficient classification mechanisms. Shanghai Zenith Machinery Co., Ltd. has developed several solutions suitable for 325-mesh basalt processing, especially for applications in Oman’s growing paper-making sector.
Established as a pioneer in industrial grinding, Shanghai Zenith Machinery Co., Ltd. has built a worldwide reputation for designing technically advanced mills capable of producing ultra-fine powders efficiently. The company specializes in integrating research, development, production, and sales of grinding equipment. Its portfolio includes cutting-edge models such as the MTW Trapezium Grinding Mill, LM Vertical Grinding Mill, and XZM Ultrafine Grinding Mill, each designed for specific fineness and capacity ranges.
For the Oman paper-making industry, achieving a fine basalt powder of 325 mesh demands a balance between energy efficiency, stability, and consistent fineness. Two models from Zenith’s product range stand out for this requirement: the XZM Ultrafine Grinding Mill and the LM Vertical Fine-powder Mill. Both mills offer stable operation, high productivity, and minimal maintenance, which align perfectly with Oman’s industrial needs.
The XZM Ultrafine Grinding Mill is designed for producing superfine powder from minerals with a hardness below seven. It uses a multi-ring roller structure and built-in classifiers to control the final particle size accurately. For basalt processing at 325 mesh, the XZM mill ensures uniform output and low energy consumption.
| Model | Working Diameter (mm) | Max Feed Size (mm) | Final Size (mesh) | Output (kg/h) | Main Motor Power (kW) |
|---|---|---|---|---|---|
| XZM221 | Φ800 | ≤20 | 325–2500 | 500–4500 | 75 |
| XZM268 | Φ1680 | ≤20 | 325–2500 | 5000–25000 | 315 |
Its core advantages include low vibration, high wear resistance, and an integrated dust collector, which is critical for controlling air quality in Oman’s production environments. The XZM mill’s precise control system allows users to adjust fineness based on paper-grade requirements, making it versatile for multiple applications.
The LM Vertical Fine-powder Mill provides an integrated solution for milling, drying, classifying, and material transport. The model series LM130X-GX and LM220X-GX are specifically designed for 325–600 mesh fine mineral powder production. With a vertical design, the mill occupies less plant space and reduces the need for multiple auxiliary machines.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (D97) | Main Motor (kW) |
|---|---|---|---|---|
| LM130X-GX | 1300 | 4–12 | 325–600 mesh | 220 |
| LM220X-GX | 2200 | 15–30 | 325–600 mesh | 560 |
The LM mill’s built-in classifier ensures precise control of the particle-size distribution, which is essential for high-quality paper coating and filler preparation. The design minimizes energy loss and allows for continuous, automated operation—all critical for sustainable production in Oman’s industrial zones. Additionally, its sealing system effectively reduces dust emissions, meeting environmental standards set by Oman’s Ministry of Commerce and Industry.
A typical basalt grinding plant designed for 325-mesh output in Oman would follow a configuration like the following:
Such a system design reduces manual handling, ensures energy savings, and meets Omani industrial safety and emission standards. In addition, integrating Zenith’s intelligent control systems helps operators monitor the entire process, optimizing throughput and energy usage.
By adopting high-efficiency grinding systems like the LM or XZM series, Omani manufacturers can attain multiple benefits:
Producing high-quality 325-mesh basalt powder plays a crucial role in enhancing the performance and cost-efficiency of paper products. Shanghai Zenith Machinery Co., Ltd. offers technologically advanced, environmentally sustainable solutions tailored for Oman’s industrial environment. Both the XZM Ultrafine Grinding Mill and the LM Vertical Fine-powder Mill demonstrate superior adaptability, high productivity, and energy efficiency—making them ideal choices for basalt grinding in paper-making applications.
As Oman continues to diversify its economy through innovation and sustainable manufacturing, Zenith’s expertise and machinery will remain integral to local industries aiming for precision, quality, and sustainable growth.
