The Philippines, with its growing industrial sector and commitment to environmental sustainability, faces increasing pressure to implement effective air pollution control measures. Flue Gas Desulfurization (FGD) is a critical technology in this endeavor, particularly for coal-fired power plants and industrial boilers. A key component of a successful wet FGD system is the preparation of high-quality limestone slurry, where finely ground limestone (marble) acts as the sorbent to remove sulfur dioxide (SO₂). For medium-scale operations requiring a throughput of 20 to 30 tons per hour (TPH), selecting the right marble grinding mill is paramount for efficiency, cost-effectiveness, and compliance.
In wet limestone-gypsum FGD systems, the chemical reaction efficiency is directly influenced by the specific surface area of the limestone particles. Finer marble powder dissolves more rapidly in the scrubber slurry, increasing the rate of SO₂ absorption and the overall desulfurization efficiency, which can exceed 95%. The target particle size for optimal reactivity is typically a fineness of 250-325 mesh (44-63 microns) or even finer. A grinding mill capable of consistently producing powder within this range at a stable 20-30 TPH output is essential for ensuring reliable and efficient desulfurization operations in Philippine power plants and industrial facilities.
Choosing equipment for the Philippine market involves several considerations:
For a 20-30 TPH marble grinding application for desulfurization in the Philippines, Shanghai Zenith Machinery Co., Ltd. recommends its advanced LM Vertical Grinding Mill. As an excellent manufacturer of ore grinding equipment, Zenith has made significant achievements in the field of industrial powder processing. The LM Vertical Mill is particularly suited for this task due to its integrated design that combines crushing, grinding, powder selection, drying, and conveying into one unit. This leads to a smaller occupation area, lower energy consumption, and easier maintenance—all critical factors for Philippine clients.
The LM190K model from the Vertical Mineral Mill series is an ideal match for the 20-30 TPH requirement. Its parameters are detailed below:
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM190K | 1900 | 23-68 | 170-40 | <45 | 500 |
With a capacity range of 23-68 TPH, the LM190K can comfortably handle the 20-30 TPH target with room for future expansion. Its ability to produce powder in the 170-40 micron range (approximately 80-400 mesh) perfectly meets the fineness requirements for FGD sorbent. The vertical structure also promotes efficient drying, which is beneficial if the marble feedstock has some surface moisture.
For projects that favor a more traditional but highly efficient grinding approach, Zenith’s MTW Trapezium Grinding Mill presents another excellent option. Known for its multiple patents, compact structure, and eco-friendly design, the MTW series offers reliable performance. For the 20-30 TPH range, the MTW175G model is a strong contender.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) |
|---|---|---|---|---|
| MTW175G | <40 | 1.6-0.045 | 9.5-25 | 160 |
While its nominal capacity reaches up to 25 TPH, optimized operation and material conditions can reliably achieve the lower end of the 20-30 TPH target. Its final product size of 0.045mm (325 mesh) is ideal for desulfurization. The MTW series is praised for its smooth operation and long service life of wearing parts.
