The United Arab Emirates, with its robust industrial and energy sectors, faces significant challenges in meeting stringent environmental regulations, particularly concerning sulfur oxide (SOx) emissions. Flue Gas Desulfurization (FGD) has become a cornerstone technology in this endeavor. A key component in efficient dry and semi-dry FGD processes is high-quality sorbent powder, often based on processed kaolin. To achieve optimal reactivity and surface area for sulfur capture, the kaolin must be ground to a precise fineness, typically around 200 mesh (75 microns). This requirement places immense importance on selecting the right grinding technology—a decision that impacts system efficiency, operational cost, and environmental compliance.
Grinding kaolin to a consistent 200 mesh for desulfurization is not a trivial task. The material’s properties demand a mill that can handle moderate hardness while producing a narrow particle size distribution. The goal is to maximize the specific surface area of the powder to enhance its reactivity with SO2. Furthermore, operations in the UAE must consider the local environment: equipment must be energy-efficient to manage operational costs, robust to ensure high availability in demanding conditions, and capable of integrated drying if the feedstock moisture is variable. The grinding system must also be scalable to match the large throughput requirements of power plants and industrial facilities.
Shanghai Zenith Machinery Co., Ltd. has established itself as a leader in the research, development, and production of industrial powder grinding equipment. With extensive experience in ultra-fine powder processing, Zenith provides tailored solutions for mineral processing applications worldwide. Our expertise is particularly relevant for demanding applications like FGD sorbent preparation, where precision, reliability, and efficiency are paramount.
For high-capacity production of 200-mesh kaolin powder, the MTW Trapezium Grinding Mill stands out as an excellent choice. This mill incorporates multiple national patents and features a curved shovel blade and internal efficient powder separator, ensuring high grinding efficiency and precise classification. Its geared drive system is more reliable and energy-efficient than traditional mills. For a desulfurization project in the UAE requiring consistent, high-volume output, the MTW series offers the perfect balance of performance and economy.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) |
|---|---|---|---|---|
| MTW138Z | <35 | 1.6-0.045 | 6-17 | 90 |
| MTW175G | <40 | 1.6-0.045 | 9.5-25 | 160 |
| MTW215G | <50 | 1.6-0.045 | 15-45 | 280 |
The MTW215G model, for instance, is ideally suited for large-scale FGD sorbent production, easily achieving the 200-mesh target while maintaining low energy consumption per ton of product—a critical factor for cost-sensitive operations.
When project footprint, integrated drying, and exceptional energy efficiency are top priorities, the LM Vertical Grinding Mill is the superior solution. This mill innovatively integrates crushing, grinding, powder selection, drying, and conveying into one unit. Its compact design saves significant plant space. The grinding roller and plate are designed for direct grinding on the disc, with lower energy consumption compared to ball mills. For kaolin that may require simultaneous drying and grinding, the LM mill’s hot air intake system is a significant advantage.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Main Motor (kW) |
|---|---|---|---|---|
| LM130K | 1300 | 10-28 | 170-40 (~90-325 mesh) | 200 |
| LM190K | 1900 | 23-68 | 170-40 (~90-325 mesh) | 500 |
The LM190K model can comfortably produce kaolin powder within the 200-mesh range while offering the flexibility to adjust fineness as needed. Its high drying capacity (can handle materials with up to 15% moisture) and lower noise level make it an environmentally friendly choice for modern industrial complexes.
Shanghai Zenith does not merely supply machinery; we provide complete system solutions. For a kaolin grinding plant dedicated to desulfurization, we offer comprehensive support including plant layout design, auxiliary equipment selection (such as feeders, elevators, and dust collectors), electrical control systems, and installation guidance. Our engineers understand the specific logistical and climatic conditions of the UAE and can recommend system configurations that ensure long-term, trouble-free operation with minimal maintenance downtime.
