Iraq, a country rich in mineral resources, has been steadily developing its metallurgical industry. Among the various raw materials used in steelmaking and non-ferrous metal smelting, basalt plays a crucial role as a flux. Basalt, when ground to a fine powder (typically 325 mesh or approximately 44 microns), acts as an efficient fluxing agent, helping to lower the melting point of slag, improve fluidity, and enhance the removal of impurities. This results in higher metal recovery rates, reduced energy consumption, and improved overall process economics.
However, the success of using basalt as a metallurgical flux heavily depends on the quality and consistency of the grinding process. In Iraq’s challenging climate and industrial environment, reliable, energy-efficient, and high-capacity grinding mills are essential to produce the required 325 mesh (D97 ≤ 44 μm) basalt powder. This article provides an in‑depth analysis of basalt grinding technology for metallurgy flux applications in Iraq, and introduces advanced milling solutions from Shanghai Zenith Machinery Co., Ltd., a world‑class manufacturer of ore grinding equipment.

Basalt is a dark, fine‑grained volcanic rock with a Mohs hardness of 5–6 and a high content of silica, alumina, iron oxides, and alkaline earth oxides. For fluxing applications, the following specifications are typical:
Grinding basalt to such fineness is challenging due to its abrasive nature. Conventional ball mills and Raymond mills may suffer from high wear rates and low energy efficiency. Therefore, modern vertical roller mills or advanced trapezium mills are preferred for their superior performance and longer service life.
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 offers a comprehensive range of mills suitable for basalt flux production: MTW Trapezium Grinding Mill, LM Vertical Grinding Mill, MTM Medium‑Speed Grinding Mill, Raymond Mill, LUM Ultrafine Vertical Mill, XZM Ultrafine Grinding Mill, Hammer Mill, and Ball Mill.
For the specific application of basalt grinding mill for metallurgy flux in Iraq with 325 mesh, two models stand out as the most cost‑effective and technically superior choices: the MTW215G Trapezium Grinding Mill and the LM220X‑GX Vertical Fine‑powder Mill. Both are capable of producing 325‑mesh basalt powder with high efficiency, low operating cost, and exceptional reliability.
The MTW series is a flagship product of Zenith, with multiple international patents. Its compact structure, long service life, and eco‑friendly design make it ideal for abrasive materials like basalt. The MTW215G model, in particular, offers a maximum feed size of 50 mm and a final product fineness adjustable from 1.6 mm down to 0.038 mm (400 mesh). For 325 mesh production, the mill operates with high throughput and low specific energy consumption.

Key benefits of the MTW215G for basalt flux production:
The LM series vertical mill integrates crushing, grinding, drying, classifying, and conveying in one unit. It is especially suitable for large‑scale basalt flux production. The LM220X‑GX model is designed for fine powder applications with an output fineness ranging from 325 to 600 mesh (D97). Its compact footprint and high capacity make it perfect for Iraq’s industrial plants where space and energy efficiency are critical.
| Parameter | Value |
|---|---|
| Plate Diameter (mm) | 2200 |
| Capacity (t/h) | 15 – 30 |
| Output Fineness (D97) | 325 – 600 mesh (44 – 23 μm) |
| Max Feed Size (mm) | ≤ 45 |
| Main Motor Power (kW) | 560 |
| Drying Capability | Built‑in hot air system, suitable for moist raw materials |
| Classifier | Dynamic classifier with variable frequency drive |
Advantages of the LM220X‑GX for Iraq’s basalt flux:

A typical basalt grinding plant for metallurgy flux in Iraq consists of the following stages:
Both the MTW215G and the LM220X‑GX can be configured with a complete line including feeder, conveyor, dust collector, and control cabinet. Zenith provides turnkey solutions and after‑sales support globally, including in the Middle East.
Basalt is an excellent fluxing material for the metallurgical industry in Iraq, and grinding it to 325 mesh is a critical step that demands robust, efficient, and reliable equipment. Shanghai Zenith Machinery Co., Ltd. offers two outstanding mill options: the MTW215G Trapezium Grinding Mill (capacity 15–45 t/h) and the LM220X‑GX Vertical Fine‑powder Mill (capacity 15–30 t/h). Both can consistently produce high‑quality 325 mesh basalt powder with low operating costs and minimal downtime. By investing in Zenith’s advanced grinding technology, Iraqi metallurgical plants can enhance their flux performance, improve metal recovery, and achieve greater profitability.
