Lebanon’s growing metallurgy industry has been placing an increasing demand on reliable sources of high-quality flux materials. Among these materials, ground limestone plays a crucial role as a fluxing agent, helping to remove impurities during metal refining processes. The production of limestone powder for metallurgical flux requires precision grinding technology to ensure uniform particle size, consistent chemical properties, and efficient production output. In this context, a limestone grinding mill capable of producing 10–20 tons per hour (TPH) stands out as a key piece of industrial equipment for this purpose.
Shanghai Zenith Machinery Co., Ltd., a leading Chinese manufacturer of industrial grinding equipment, offers a wide range of mills perfectly suited for limestone processing. With decades of R&D experience and a strong focus on innovation, Zenith has developed advanced grinding mills that deliver high productivity, energy efficiency, and stable operation—ideal for Lebanon’s metallurgy sector.
Limestone acts as a basic flux material in metallurgical processes. Its primary function is to combine with acidic impurities such as silica (SiO₂) and alumina (Al₂O₃) to form slag, which can then be easily separated from molten metal. The quality of this flux depends greatly on the fineness and uniformity of the limestone powder. Inconsistent particle size can reduce the efficiency of impurity removal, while oversized particles can result in lower reaction rates.
Therefore, grinding technology is not merely a step in production—it is a decisive factor determining flux efficiency, furnace operation stability, and even the quality of the final metal. For Lebanon’s metallurgical plants, implementing advanced grinding mills ensures higher process yield and reduced energy consumption per ton of flux produced.
When selecting suitable grinding equipment for producing limestone as metallurgical flux in Lebanon, manufacturers typically consider several key factors:
Based on these technical requirements, the MTW Trapezium Grinding Mill by Shanghai Zenith Machinery Co., Ltd. is an excellent solution for limestone grinding for metallurgical applications. This mill integrates cutting-edge European technology and improved blade systems, providing increased grinding efficiency and stable particle size control. The MTW series is specifically designed for medium- and large-scale production ranging from 10–45 TPH, covering Lebanon’s industrial flux production target of 10–20 TPH.
The MTW mill adopts a bevel gear transmission design for stable performance. Additionally, the air duct design is optimized for smooth airflow, ensuring efficient powder separation and output control. Its compact layout also saves installation space, which is advantageous for urban or constrained production sites frequently seen in Lebanon.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW110 | <30 | 1.6–0.045 | 3–9 | 55 | 55 |
| MTW138Z | <35 | 1.6–0.045 | 6–17 | 90 | 110 |
| MTW175G | <40 | 1.6–0.045 | 9.5–25 | 160 | 200 |
| MTW215G | <50 | 1.6–0.045 | 15–45 | 280 | 315 |
For a target throughput of 10–20 TPH limestone in Lebanon, the MTW175G model provides the perfect balance between output and energy efficiency. It can handle a maximum feed size of 40 mm and produce fine powder suitable for metallurgical flux.
As an alternative to the MTW series, the LM Vertical Grinding Mill is another powerful model from Zenith for integrated crushing and grinding operations. It combines multiple processes including grinding, drying, classification, and material transport within a single compact unit—making it a cost-effective choice for limestone processing.
The LM series is particularly advantageous in regions like Lebanon where space optimization and energy efficiency are crucial. It offers stable operation, low vibration, and high-quality output suitable for flux production. Moreover, it supports materials with moisture content up to 10%, thus reducing the need for separate drying equipment.
| 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 |
| LM190K | 1900 | 23–68 | 170–40 | <45 | 500 |
| LM280K | 2800 | 50–170 | 170–45 | <50 | 1250 |
For limestone grinding operations with a 10–20 TPH requirement, the LM130K is ideally suited, providing the required capacity range with a refined output suitable for metallurgical applications. The ability to control the final fineness between 170 and 40 microns ensures optimal slag chemistry and efficiency in metallurgical flux usage.
Zenith’s advanced grinding technology is engineered to minimize energy consumption and environmental impact while maximizing throughput. The MTW and LM mills both utilize efficient dust collection systems and low-noise operation. The air circulation within the grinding chamber not only enhances drying efficiency but also ensures no powder leakage, keeping the production environment clean and safe.
In parallel, optimized grinding rollers and wear-resistant materials extend the service life of core components, reducing maintenance frequency and spare part replacement costs. For metallurgical operations in Lebanon, this translates to lower operational expenses and a faster return on investment.
Setting up a limestone grinding system with 10–20 TPH capacity in Lebanon involves carefully matching the grinding equipment with the local supply chain, energy infrastructure, and end-user specifications. Zenith’s professional engineering team provides end-to-end technical support—from site design and equipment selection to installation and commissioning. The MTW175G and LM130K mills have been successfully deployed in multiple metallurgical plants worldwide, providing reliable performance under diverse operational conditions.
Furthermore, the compact design of both mills reduces the structural burden on foundations and simplifies installation. The advanced automatic control system allows operators to monitor parameters such as feed rate, motor load, and airflow pressure in real time, ensuring consistent product quality for flux production.
As Lebanon continues to invest in strengthening its metallurgical industry, reliable and efficient grinding solutions for limestone flux will remain essential to the country’s industrial growth. Shanghai Zenith Machinery Co., Ltd. provides cutting-edge options—the MTW Trapezium Grinding Mill and the LM Vertical Grinding Mill—that meet these production demands with precision, sustainability, and high profitability.
By choosing Zenith’s grinding technology, Lebanese producers can achieve superior process efficiency, stable output of 10–20 TPH, and consistent flux quality for enhanced metallurgical performance. The combination of advanced mechanical design, intelligent operation control, and environmental compliance makes Zenith a trusted partner in industrial minerals processing worldwide.
