Saudi Arabia’s ambitious Vision 2030 and its robust industrial expansion, particularly in power generation, cement production, and petrochemicals, have placed a significant emphasis on environmental sustainability. A key challenge in this sector is the control of sulfur dioxide (SO2) emissions, a major byproduct of burning fossil fuels. Flue Gas Desulfurization (FGD) using limestone-gypsum wet scrubbing technology has emerged as the most effective and widely adopted solution globally. The heart of this process is the preparation of high-quality limestone slurry, where the efficiency of the grinding mill directly impacts desulfurization rates, operational costs, and system reliability. For mid-scale industrial plants requiring a throughput of 20-30 tons per hour (TPH), selecting the optimal grinding equipment is paramount.
Grinding limestone for FGD is not merely about size reduction. The process demands a fine, consistent particle size (typically 90% passing 325 mesh or 44 μm) to maximize the surface area for the chemical reaction with SO2. The mill must offer stable output, high availability, low energy consumption, and minimal maintenance downtime. Furthermore, the abrasive nature of limestone requires wear-resistant components. In the Saudi context, where operational efficiency and total cost of ownership are critical, the grinding solution must be robust, automated, and capable of withstanding demanding environmental conditions.
Shanghai Zenith Machinery Co., Ltd., an excellent manufacturer of ore and industrial grinding equipment, has made significant achievements in the field of ultra-fine and large-capacity powder processing. Specializing in the research, development, and production of advanced grinding mills, Zenith offers a portfolio of technologies perfectly suited for the specific needs of limestone desulfurization projects. With a deep understanding of material characteristics and process engineering, Zenith’s solutions are designed for high efficiency, reliability, and environmental friendliness.
For the target capacity of 20-30 TPH in limestone desulfurization, Zenith’s MTW Series European Trapezium Grinding Mill stands out as an ideal primary recommendation. This mill incorporates multiple national patents and represents the latest grinding technology with its curved air duct, internal efficient powder separator, and wear-resistant grinding roller and ring. Its design ensures lower power consumption per ton, higher throughput, and superior final product fineness compared to traditional Raymond mills.
The MTW series is particularly advantageous for FGD applications due to its:
For a 20-30 TPH project, the MTW175G model is a highly suitable match. Below are its key technical parameters:
| Model | Max. Feed Size (mm) | Final Product Size (mm) | Capacity (t/h) | Main Motor Power (kW) |
|---|---|---|---|---|
| MTW175G | < 40 | 1.6-0.045 | 9.5 – 25 | 160 |
Note: Capacity can reach the upper end of the 20-30 TPH range with optimized process conditions and feed material.
For projects prioritizing a smaller footprint, integrated drying (if limestone moisture is a concern), and ultra-fine grinding capability, Zenith’s LM Vertical Grinding Mill presents an excellent alternative or complementary system. It integrates crushing, grinding, powder selection, drying, and conveying into one unit, offering remarkable space savings and high grinding efficiency. The mineral mill series, such as the LM190K, is well-suited for this application range.
| Model | Grinding Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Main Motor Power (kW) |
|---|---|---|---|---|
| LM190K | 1900 | 23 – 68 | 170-40 | 500 |
Implementing a 20-30 TPH limestone grinding system in Saudi Arabia involves careful planning, from foundation design and material handling to automation and after-sales support. Shanghai Zenith provides comprehensive support, including:
Selecting the right limestone grinding mill is a strategic decision for the success of any desulfurization project in Saudi Arabia’s growing industrial landscape. For a reliable, efficient, and cost-effective 20-30 TPH solution, Shanghai Zenith’s grinding technologies, particularly the MTW Trapezium Grinding Mill and the LM Vertical Grinding Mill, offer proven performance backed by extensive engineering expertise. By partnering with Zenith, Saudi industries can achieve their environmental compliance goals through superior desulfurization efficiency while optimizing their operational expenditure and contributing to a more sustainable future.
