The ceramic industry in Oman, renowned for its rich heritage and modern manufacturing ambitions, places stringent demands on raw material quality. Among these, bentonite clay stands as a critical component, valued for its plasticity, binding strength, and green strength in ceramic bodies and glazes. To unlock its full potential, achieving a consistent and fine particle size—specifically around 150 mesh (approximately 100 microns)—is paramount. This process requires precision grinding technology that balances efficiency, product quality, and operational cost. Shanghai Zenith Machinery Co., Ltd., an excellent manufacturer of ore and industrial powder grinding equipment, offers tailored solutions that meet these exacting requirements for Omani ceramic producers.
Bentonite is an aluminosilicate clay mineral primarily composed of montmorillonite. In ceramic applications, its exceptional properties are harnessed to improve workability, dry strength, and suspension stability. A finely ground bentonite powder, such as one graded at 150 mesh, ensures uniform dispersion within the ceramic slurry, leading to enhanced plasticity for shaping, reduced cracking during drying, and improved final product density and surface finish. The grinding process must therefore not only reduce particle size but also preserve the mineral’s natural laminar structure and chemical properties, which can be compromised by excessive heat or inefficient milling.
Grinding bentonite presents unique challenges. Its natural moisture content, abrasiveness, and tendency to agglomerate demand robust yet controlled milling systems. Traditional grinding methods may lead to inconsistent particle size distribution, high energy consumption, or overheating, which can degrade the clay’s binding properties. For Omani manufacturers targeting high-value ceramic products, a grinding solution must offer:
Shanghai Zenith Machinery Co., Ltd. specializes in the research, development, and production of industrial powder grinding equipment. With deep expertise in ultra-fine powder processing, Zenith provides technologies ideally suited for transforming Omani bentonite into a premium ceramic ingredient. For the specific target of 150 mesh, two of our product lines stand out for their efficiency and reliability.
For high-capacity production of bentonite powder at 150 mesh, the MTW Trapezium Grinding Mill is an outstanding choice. This mill incorporates multiple national patents, featuring a curved air duct design that reduces airflow resistance and a internal powder separator for high-precision classification. Its geared drive system is more efficient and reliable than traditional worm gear reducers. For Omani ceramic plants requiring steady, large-volume output, the MTW series ensures the desired fineness with excellent energy savings.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) |
|---|---|---|---|---|
| MTW138Z | <35 | 1.6-0.045 (approx. 10-325 mesh) | 6-17 | 90 |
| MTW175G | <40 | 1.6-0.045 | 9.5-25 | 160 |
Note: The 150 mesh target (~0.1mm) falls comfortably within the adjustable output range of these models.
When the focus is on superior product quality, stability, and integrated processing, the LUM Ultrafine Vertical Mill is the premier option. This mill integrates grinding, drying, classifying, and conveying in one compact unit. Its advanced material bed grinding principle and efficient classifier are perfect for achieving a consistent 150 mesh fineness while minimizing over-grinding. The system’s intelligent control allows for precise adjustment and stable operation, crucial for maintaining the quality standards of ceramic-grade bentonite.
| Model | Main Machine Power (kW) | Capacity (t/h) | Size Distribution D97 (μm) |
|---|---|---|---|
| LUM1525 | 220-250 | 1.6-11.5 | 5-30 (Approx. 600-2500 mesh, adjustable to coarser sizes) |
| LUM1632 | 280-315 | 2.0-13.5 | 5-30 |
Note: The LUM mill’s classifier can be precisely tuned to produce a top-cut at 150 mesh, ensuring no coarse particles contaminate the final product.
