Vietnam has emerged as a significant hub for glass manufacturing in Southeast Asia, driven by the steady growth of construction, automotive, and consumer goods industries. Among the key raw materials used in glass production, perlite—a naturally occurring volcanic glass that expands when heated—plays an essential role. To achieve the required fineness suitable for glassmaking, perlite must undergo efficient grinding. The choice of a high-quality, reliable grinding mill is vital to ensure both productivity and product consistency.
Shanghai Zenith Machinery Co., Ltd., a renowned manufacturer of industrial grinding equipment in China, offers advanced solutions for perlite processing, helping glass manufacturers achieve output capacities between 5–10 tons per hour (TPH) with precision and efficiency.
Perlite is an amorphous volcanic rock that expands up to 20 times its original volume when heated rapidly. This characteristic makes it suitable as a lightweight aggregate in building materials and as a flux in glass production. In the glass industry, perlite functions as a fluxing agent, reducing the melting temperature of silica and enhancing the clarity and homogeneity of the final product.
To make perlite suitable for use in glass manufacturing, it must be ground to fine powders—commonly between 80 to 400 mesh. The grinding process directly affects the reactivity of perlite during melting and the quality of the produced glass. Therefore, a robust grinding system capable of stable, uniform, and energy-efficient production is indispensable.
The Vietnam glass market increasingly demands perlite with a capacity range of 5–10 TPH due to the medium-scale glass production operations prevalent in the region. Several local companies aim to reduce dependency on imported raw materials by developing in-country perlite processing facilities. In such settings, flexible grinding systems that can handle varying feed sizes and moisture contents are crucial.
Shanghai Zenith Machinery Co., Ltd. provides multiple models perfectly suited for these requirements. Two recommended solutions for perlite grinding to support 5–10 TPH in glass manufacturing are the MTW Trapezium Grinding Mill and the LM Vertical Grinding Mill.
The MTW Trapezium Grinding Mill from Shanghai Zenith Machinery Co., Ltd. combines European technology and rigorous engineering to deliver energy-efficient, cost-effective, and high-performance perlite milling solutions. Designed for medium capacity production lines, it ensures excellent grinding stability even when processing abrasive volcanic materials like perlite.
Key features include:
The table below summarizes the key technical parameters of suitable MTW series models for achieving 5–10 TPH output in perlite grinding.
| 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 |
| MTW110Z | <30 | 1.6–0.045 | 3–10 | 55 | 55 |
| MTW138Z | <35 | 1.6–0.045 | 6–17 | 90 | 110 |
The MTW110Z model is particularly suitable for achieving 5–10 TPH perlite grinding capacity for medium-scale glassmaking operations in Vietnam. It provides a balanced combination of efficiency, reliability, and simplicity in maintenance.
For factories requiring higher automation and integration, the LM Vertical Grinding Mill is another powerful solution from Shanghai Zenith. It integrates crushing, grinding, drying, and classifying into a single machine, minimizing auxiliary equipment cost and space occupation—a particularly valuable advantage for local enterprises with limited plant area in Vietnam.
Highlights of the LM Vertical Grinding Mill include:
| 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 |
For a production target between 5–10 TPH, the LM130K model can be adjusted to operate within the lower end of its capacity range, ensuring high product quality and consistent performance while leaving operational room for production expansion.
