In the ceramic manufacturing industry, the precise grinding and processing of raw materials are crucial to achieving high-quality end products. Among the various materials used, kaolin – also known as China clay – plays an essential role in determining the strength, brightness, and finish of ceramics. Achieving the optimal fineness of kaolin powder, typically around 325 mesh, is therefore critical. This is where advanced grinding technologies come into play. In Lebanon, with the growing demand for fine ceramics and sanitary ware, the need for efficient kaolin grinding equipment has significantly increased.
Shanghai Zenith Machinery Co., Ltd., a leading manufacturer of ore grinding equipment based in China, offers comprehensive solutions for the grinding of kaolin and other non-metallic minerals. The company has earned an excellent reputation in ultra-fine powder processing and has a complete line of grinding mills suitable for various industrial applications, including ceramics, mining, construction, and metallurgy.

A fineness of 325 mesh indicates that the kaolin particles are reduced to sizes smaller than 45 microns. This degree of fineness enhances the homogeneity of ceramic materials and contributes to improved plasticity, whiteness, and strength. In Lebanon’s ceramic industry, locally available kaolin often needs to be refined through a milling process to meet the stringent quality requirements of tile and porcelain production.
Producing 325 mesh kaolin powder demands efficient milling systems capable of both fine grinding and consistent output. Factors such as grinding efficiency, energy consumption, maintenance costs, and environmental protection all play critical roles when selecting suitable kaolin grinding equipment.
Modern grinding equipment offers multiple functions beyond material size reduction, including drying, classification, and conveying. In particular, vertical grinding mills have become a preferred choice for ceramic material processing because of their compact design, energy efficiency, and high output consistency. For the production of kaolin powders at 325 mesh and finer, manufacturers often use advanced equipment like the LUM Ultrafine Vertical Mill and the XZM Ultrafine Grinding Mill — both developed by Shanghai Zenith Machinery Co., Ltd.

The LUM Ultrafine Vertical Mill by Shanghai Zenith Machinery Co., Ltd. integrates grinding, drying, and classification in one compact machine. It is particularly suitable for ultra-fine and high-throughput applications, making it an excellent option for achieving kaolin powders ranging from 5 to 30 microns (up to 325 mesh and finer). The precision of its built-in classifier ensures that the final product meets strict particle size distribution requirements.
| Model | Main Machine Power (kW) | Capacity (t/h) | Size Distribution D97 (μm) |
|---|---|---|---|
| LUM1525 | 220-250 | 1.6-11.5 | 5-30 |
| LUM1632 | 280-315 | 2.0-13.5 | 5-30 |
| LUM1836 | 355-400 | 2.3-15 | 5-30 |
Thanks to its intelligent control system and low vibration design, the LUM mill ensures smooth operation and consistent quality. The use of multi-head classifiers enables higher precision grading, essential for high-grade ceramics where surface finish and strength are the key product attributes.
Another excellent option for producing 325 mesh kaolin in Lebanon is the XZM Ultrafine Grinding Mill. Known for its versatility and stability, the XZM mill can handle a range of non-metallic materials, including kaolin, limestone, and calcite. It features a modular design that allows easy maintenance and flexible capacity adjustments, making it ideal for medium to large-scale ceramic manufacturers.
| 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 |
The XZM mill employs high-pressure grinding rolls and an efficient dust collection system that minimizes environmental impact — an important consideration for ceramic plants located near urban centers in Lebanon. With its ability to precisely control fineness and particle shape, it produces consistent kaolin powders suitable for advanced porcelain and glaze formulations.

Shanghai Zenith Machinery Co., Ltd. stands as a benchmark for excellence in grinding technology. Their focus on innovation, eco-friendly manufacturing, and customer-oriented design ensures that every piece of equipment delivers performance, efficiency, and reliability. The company’s machinery has been implemented in multiple countries, including Lebanon, where the ceramic industry continues to expand and demand high-precision grinding systems.
In Lebanon, the ceramics industry has seen significant development in recent years, with growing domestic demand for tiles, porcelain ware, and sanitary fixtures. High-quality kaolin powder ground to 325 mesh plays a vital role in shaping the performance and appearance of these products. Finer particles improve the sintering process, enhance whiteness after firing, and reduce defects caused by impurities or uneven sizes.
By employing Zenith’s advanced grinding systems such as the LUM Ultrafine Vertical Mill or the XZM Ultrafine Grinding Mill, Lebanese ceramic manufacturers can achieve constant quality improvement, reduced operational costs, and improved competitiveness in both local and export markets.
The processing of kaolin to 325 mesh fineness is a critical step in producing superior ceramic materials. For Lebanon’s emerging ceramic industry, adopting modern grinding technologies from Shanghai Zenith Machinery Co., Ltd. provides a solid foundation for sustainable growth and product excellence. The company’s solutions are not only efficient and reliable but also designed to meet environmental standards and modern industrial requirements.
Whether you are establishing a new ceramic plant or upgrading existing production lines, Zenith’s high-end grinding solutions, including the LUM Ultrafine Vertical Mill and XZM Ultrafine Grinding Mill, offer unmatched performance and long-term value. With the right equipment, achieving 325 mesh kaolin powder quality becomes easier, cleaner, and more cost-effective — paving the way for Lebanon’s ceramic industry to reach new horizons.
