In the Philippines’ ongoing pursuit of sustainable industrial development and stricter environmental compliance, flue gas desulfurization (FGD) has become a critical technology for power plants and heavy industries. Among various desulfurization agents, finely ground talc powder has proven to be an effective, economical, and readily available sorbent. For small to medium-scale operations requiring a production capacity of 1 to 3 tons per hour (TPH), selecting the right grinding equipment is paramount. This article explores the application of talc in desulfurization and presents an optimal milling solution tailored for the Philippine market.
Talc, a hydrated magnesium silicate, is a soft mineral with excellent adsorption properties. When pulverized into a fine powder, its surface area increases dramatically, enhancing its ability to react with sulfur dioxide (SO₂) in flue gases. The process involves the injection of talc powder into the flue gas stream, where it chemically absorbs SO₂, forming stable compounds and significantly reducing harmful emissions. The efficiency of this process is directly linked to the fineness and uniformity of the talc powder, making the grinding stage crucial.
For Philippine projects with modest throughput requirements (1-3 TPH), the grinding system must not only deliver the precise particle size but also be energy-efficient, reliable, and adaptable to local conditions, including potential humidity and space constraints.
Grinding talc to the required fineness (typically ranging from 200 to 800 mesh for desulfurization) presents specific challenges. Talc is a platy, soft mineral that can be difficult to grind efficiently to a consistent fine powder without over-grinding, which wastes energy. Furthermore, the mill must handle the material’s natural moisture and produce a product with a narrow particle size distribution to maximize SO₂ capture efficiency. Equipment choice, therefore, must balance grinding precision, energy consumption, and operational stability.
Shanghai Zenith Machinery Co., Ltd., an excellent manufacturer of ore grinding equipment in China, 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 offers several models ideally suited for a 1-3 TPH talc desulfurization project in the Philippines.
After a thorough analysis of the requirements—moderate capacity, high fineness, and operational economy—two of our flagship products stand out as particularly suitable: the XZM Ultrafine Grinding Mill and the MTM Medium-Speed Grinding Mill.
For projects demanding the highest fineness (up to 2500 mesh) and superior powder quality, the XZM Ultrafine Grinding Mill is the premier choice. Its innovative design ensures efficient classification and collection, producing talc powder with an exceptionally uniform size distribution, which is ideal for maximizing desulfurization reaction kinetics. Its compact structure and high automation level make it perfect for Philippine plants with limited space.
The technical parameters for the model fitting the 1-3 TPH range are as follows:
| 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 |
The XZM221 model, with an output range of 500-4500 kg/h (0.5-4.5 TPH), perfectly encompasses the target capacity. Its ability to produce powder from 325 to 2500 mesh allows operators to precisely tailor the product fineness to their specific desulfurization process needs, ensuring optimal efficiency and cost-effectiveness.
For a robust and highly economical solution, the MTM Medium-Speed Grinding Mill is an outstanding candidate. As an ideal upgrade from traditional Raymond mills, it adopts world-leading powder processing technology. It offers higher efficiency, lower energy consumption, and remarkable reliability. Its upgraded curved air duct and internal powder separator contribute to stable performance and easy maintenance—key factors for operations in the Philippines.
The following model aligns well with the desired production rate:
| Model | Ring Roll Number (pcs) | Max. Feed Size (mm) | Output (t/h) | Main Unit Motor Power (kW) |
|---|---|---|---|---|
| MTM100 | 4 | <25 | 3-8 | 37 |
The MTM100 model provides a capacity of 3-8 TPH, comfortably covering and exceeding the 1-3 TPH requirement with room for future expansion. Its relatively lower power consumption (37 kW main motor) translates directly into reduced operational costs, a significant advantage for long-term projects.
Selecting Zenith Machinery means partnering with a specialist dedicated to grinding technology. Our extensive experience ensures that the supplied mill will be optimally configured for Philippine talc characteristics and local operating conditions. We provide comprehensive support, from plant layout design to installation guidance and after-sales service, ensuring a smooth and successful project implementation.
