In Bangladesh, the engineered stone industry has been growing rapidly thanks to rising demand for high-quality decorative and construction materials. One of the key raw materials in engineered stone production is feldspar—a mineral that provides the necessary hardness, durability, and aesthetic appeal to artificial stone surfaces. To achieve the desired quality, feldspar needs to be ground into fine powder before being used in manufacturing. This is where a reliable feldspar grinding mill becomes essential, particularly for operations running between 10–20 tons per hour (TPH).
Shanghai Zenith Machinery Co., Ltd., a leading manufacturer of industrial grinding equipment from China, plays an important role in supporting this industry. With years of expertise and advanced technology, the company has supplied numerous grinding systems across Asia, including Bangladesh. Their equipment is known for its durability, energy efficiency, and precision, making it ideal for feldspar processing in engineered stone production lines.
Engineered stone, sometimes referred to as artificial or composite stone, is produced by blending finely ground minerals such as quartz, feldspar, silica, or marble with resins and pigments. Feldspar serves multiple functions in this mixture:
To ensure consistent quality, the particle size of feldspar must be tightly controlled. The final powder is typically required to have a fineness below 45 microns. Therefore, the grinding process determines the final surface properties and stability of engineered stones.
Bangladesh’s engineered stone factories generally require grinding systems that balance moderate capacity (around 10–20 TPH) with consistent fineness and low operational costs. Local conditions—such as varying feldspar hardness, humidity, and power supply—demand flexible, efficient grinding equipment. Additionally, environmental regulations increasingly require dust-free operations and lower energy consumption, putting further emphasis on advanced mill designs.
Among the available options, the MTW Trapezium Grinding Mill and the LM Vertical Grinding Mill from Shanghai Zenith Machinery Co., Ltd. have proven to be two outstanding solutions for feldspar grinding applications in Bangladesh.
The MTW series is a new generation of grinding equipment that adopts European technology. It offers high efficiency, precise particle control, and an environmentally friendly operation. For feldspar processing in the 10–20 TPH range, the MTW138Z model is particularly suitable.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW138Z | <35 | 1.6–0.045 | 6–17 | 90 | 110 |
| MTW175G | <40 | 1.6–0.045 | 9.5–25 | 160 | 200 |
The MTW Trapezium Mill’s optimized internal airflow and advanced separator help achieve consistent fineness while reducing energy consumption. Its efficient trapezium-shaped grinding roller configuration enhances the contact area between the roller and ring, increasing throughput and ensuring stable product quality.
For customers seeking vertical integration of multiple processes—crushing, drying, grinding, and material conveying—the LM Vertical Grinding Mill is an ideal solution. Especially in regions like Bangladesh where space and power utilization are critical, LM series mills integrate efficiency with compact design.
| 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 |
The LM Vertical Grinding Mill’s design allows simultaneous drying and classification, enabling operators to produce feldspar powder with moisture content below 1%. Its intelligent control system continuously adjusts grinding pressure and airflow, ensuring optimum efficiency. Moreover, the vertical structure minimizes plant footprint—an important advantage in Bangladesh’s industrial zones.
Both the MTW and LM series mills from Shanghai Zenith embody the company’s dedication to integrating multiple technologies into single efficient systems. Key advantages include:
By integrating these features, feldspar producers in Bangladesh can achieve a highly consistent product suitable for high-end engineered stone applications while enhancing profitability and sustainability.
Several engineered stone factories in Bangladesh have adopted Zenith’s grinding systems for feldspar powder preparation. In these cases, the mills operate in continuous production, supplying fine feldspar powder in the 10–20 TPH range with excellent particle uniformity. Feedback from customers highlights remarkable enhancements in production stability, energy savings, and product brightness. The improved powder quality has directly contributed to better-looking, more durable engineered stone slabs for both local consumption and export.
