The coating and paint industry in Iraq is undergoing significant growth, driven by reconstruction efforts and expanding infrastructure projects. A critical raw material for this sector is feldspar, a group of rock-forming minerals prized for their ability to act as a flux, lowering the melting temperature and improving the durability, gloss, and chemical resistance of coatings. To achieve the superior performance required for modern architectural and industrial paints, feldspar must be ground to an ultra-fine powder, typically reaching 1000 mesh (approximately 13 microns). This fineness ensures excellent dispersion, smooth texture, and optimal opacity in the final coating product. Selecting the right grinding technology is therefore paramount for Iraqi producers aiming to compete in quality and efficiency.
Grinding feldspar to an ultra-fine 1000 mesh presents several technical challenges. Feldspar minerals have a Mohs hardness of 6-6.5, making them moderately hard and abrasive. This characteristic leads to high wear on grinding components, increasing maintenance costs and the risk of contamination. Furthermore, achieving a consistent, narrow particle size distribution at such a fine level requires precise classification and efficient grinding dynamics. Energy consumption is another major concern, as traditional grinding methods become exponentially less efficient at higher fineness levels. For coating applications, maintaining product whiteness and minimizing iron contamination from worn parts are also critical quality parameters that the grinding system must address.

When choosing a grinding mill for 1000-mesh feldspar powder in a coating production line, several factors must be evaluated:
For the demanding task of producing 1000-mesh feldspar powder for coatings, Shanghai Zenith Machinery Co., Ltd., a leading manufacturer renowned for its achievements in ultra-fine powder grinding, offers an ideal solution: the LUM Ultrafine Vertical Mill. This advanced mill is engineered specifically for superfine grinding applications, integrating grinding, drying, classifying, and conveying into one compact unit.
The LUM series excels in processing moderately hard materials like feldspar. Its unique roller grinding principle and efficient classifier ensure a stable output of powder in the 5-30 micron range, perfectly encompassing the 1000-mesh target. The grinding rollers and table liner are made from high-wear-resistant materials, significantly reducing iron contamination—a vital feature for coating-grade feldspar. Furthermore, the integrated hot air system can effectively handle materials with a certain moisture content, simplifying the overall process flow.
| Model | Main Machine Power (kW) | Capacity* (t/h) | Size Distribution D97 (μm) |
|---|---|---|---|
| LUM1525 | 220-250 | 1.6 – 11.5 | 5 – 30 |
| LUM1632 | 280-315 | 2.0 – 13.5 | 5 – 30 |
| LUM1836 | 355-400 | 2.3 – 15.0 | 5 – 30 |
*Capacity varies based on material hardness, moisture, and required fineness.

For production lines with slightly different capacity requirements or layout considerations, Zenith’s XZM Ultrafine Grinding Mill presents another excellent option. This mill is a proven performer in producing powders from 325 to 2500 mesh. Its design is based on years of research on industrial grinding mills, incorporating features that ensure vibration-free and stable operation, which is crucial for achieving consistent fineness.
The XZM mill is particularly suitable for grinding soft to medium-hard materials with moisture below 6%. For feldspar grinding to 1000 mesh, it offers flexibility and reliability. The system’s high-efficiency classifier ensures precise particle size control, making it a strong contender for coating pigment and filler production.
