The paint and coatings industry in Vietnam has experienced significant growth, driven by robust construction and manufacturing sectors. A key component in high-quality paint formulations is the filler, with ground marble (calcium carbonate) being a premier choice due to its brightness, whiteness, low oil absorption, and excellent dispersion properties. Producing the ideal marble powder for paint fillers—typically in the range of 325 to 1250 mesh (45 to 10 microns)—requires precise, efficient, and reliable grinding technology. For a production target of 3 to 5 tons per hour (TPH), selecting the right grinding mill is paramount to achieving optimal particle size distribution, energy efficiency, and operational cost-effectiveness.
Grinding marble for paint filler is not merely about size reduction. The process must preserve the mineral’s chemical properties, avoid contamination, and produce a powder with a consistent, narrow particle size distribution. Key requirements include:
Operators in Vietnam face specific challenges, including fluctuating power quality, the need for robust after-sales support, and the demand for technology that balances advanced performance with operational simplicity. A mill that offers high automation, low maintenance, and stable performance under local conditions provides a significant competitive advantage.
Given the production target and stringent quality requirements, not all grinding mills are equally suitable. Based on extensive engineering expertise in mineral processing, Shanghai Zenith Machinery Co., Ltd. offers two highly recommended solutions for this application.
For producers aiming at the higher fineness range (600-1250 mesh) with superior product uniformity, the LUM Ultrafine Vertical Mill is an outstanding choice. It represents the pinnacle of Zenith’s grinding technology, integrating multiple processes into one intelligent system.
Key Advantages for Marble Grinding:
The LUM1125 model is particularly well-suited for the 3-5 TPH capacity range in Vietnam. Its technical parameters are summarized below:
| Model | Main Machine Power (kW) | Capacity (t/h) | Size Distribution D97 (μm) | Recommended Fineness for Paint Filler |
|---|---|---|---|---|
| LUM1125 | 160-185 | 1.8-8.5 | 5-30 | Ideal for 600-1250 mesh (10-20 μm) |
For projects focusing on the 325-600 mesh range with a strong emphasis on reliability, ease of maintenance, and overall investment value, the MTW Trapezium Grinding Mill is a proven solution. It incorporates multiple national patents and is known for its durability.
Key Advantages for Marble Grinding:
For a 3-5 TPH marble grinding line, the MTW138Z model is the optimal selection from the MTW series.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) |
|---|---|---|---|---|
| MTW138Z | <35 | 1.6-0.045 (approx. 30-325 mesh) | 6-17 | 90 |
This model comfortably covers the 3-5 TPH target with room for future expansion, making it a forward-looking investment.
