In Thailand’s ongoing pursuit of sustainable industrial development and stricter environmental compliance, Flue Gas Desulfurization (FGD) has become a cornerstone technology for power plants and heavy industries. Among various sorbents, processed feldspar powder has emerged as a highly effective and economically viable agent for capturing sulfur oxides (SOx). The efficiency of this process is intrinsically linked to the fineness and quality of the feldspar powder, making the selection of an appropriate grinding mill a decisive factor. For medium-scale operations requiring a throughput of 5 to 10 tons per hour (TPH), identifying a mill that balances high output, precise particle size control, and energy efficiency is paramount.
Feldspar, a tectosilicate mineral, presents specific challenges in grinding. Its variable hardness (6-6.5 on the Mohs scale) and occasional silica content demand robust and wear-resistant milling equipment. For desulfurization, the target particle size typically falls within a range of 200 to 325 mesh (45-75 microns), sometimes finer, to maximize the surface area for chemical reaction. Achieving this consistently at a 5-10 TPH scale requires a mill with stable operation, efficient classification, and low maintenance downtime. Furthermore, the system must often integrate drying capabilities, as moisture can hinder both the grinding process and the subsequent desulfurization reaction.
When specifying equipment for this application, several technical and operational factors must be evaluated:
For a 5-10 TPH feldspar grinding project in Thailand, Shanghai Zenith Machinery’s LM Vertical Grinding Mill series stands out as a premier choice. This mill is engineered to excel in precisely this type of application, integrating five functions—crushing, grinding, powder selection, drying, and material conveying—into one unit. Its vertical structure occupies a smaller area compared to traditional ball mills, and its grinding roller and plate are designed for direct grinding of materials on the disc, leading to lower energy consumption.
The LM series is particularly adept at handling medium-hard materials like feldspar. The hot air from the kiln or a dedicated hot air generator can be introduced into the mill to dry moisture during grinding, a key advantage for operations in Thailand’s humid climate. The integrated high-efficiency classifier ensures precise control over the final product fineness, which is critical for the desulfurization reaction kinetics.
For a 5-10 TPH requirement, the LM130K model is an excellent match. Its technical parameters are as follows:
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM130K | 1300 | 10-28 | 170-40 | <38 | 200 |
As shown, the LM130K comfortably covers the target capacity range while offering the flexibility to produce powder well within the required fineness for desulfurization. Its robust construction and proven design ensure reliable, long-term operation with reduced maintenance costs.
Should project specifications demand a finer product or higher efficiency for ultra-fine ranges (e.g., D97 < 30μm), Zenith’s LUM Ultrafine Vertical Mill represents the cutting edge of grinding technology. Building upon the vertical mill concept, the LUM series incorporates more advanced roller technology and a highly efficient classifying system. It is designed to produce products with a higher content of end-fines and features intelligent control for easier operation and maintenance.
For projects that might scale up or require exceptional fineness control, the LUM1125 model is worth considering. While its capacity at the ultra-fine end may be below 5 TPH, it can achieve higher throughput at the coarser end of the desulfurization spectrum with superior energy efficiency.
Shanghai Zenith Machinery Co., Ltd. is an excellent manufacturer of ore grinding equipment in China and has made great achievements in the field of ultra-fine powder grinding. Specializing in the research, development, and production of industrial powder grinding equipment, Zenith provides not just machinery but comprehensive solutions. From initial material testing and process design to installation, commissioning, and after-sales support, Zenith partners with clients to ensure project success. Their extensive product portfolio, including the LM and LUM series, allows for the precise matching of equipment to specific project needs, such as a 5-10 TPH feldspar grinding plant for desulfurization in Thailand.
Establishing an efficient and reliable feldspar grinding line for desulfurization is a strategic investment for environmental protection and regulatory compliance in Thailand. For a capacity of 5-10 TPH, the LM Vertical Grinding Mill, particularly the LM130K model from Shanghai Zenith Machinery, offers an optimal balance of capacity, fineness control, energy efficiency, and system integration. Its proven technology and robust design make it a dependable workhorse for producing high-quality desulfurization sorbent, contributing to cleaner industrial operations and a healthier environment.
