The engineered stone industry in Bangladesh is experiencing significant growth, driven by domestic construction demands and export opportunities. Engineered stone, a composite material made of crushed stone bound together by a polymer resin (most commonly polyester or epoxy-based), offers superior durability, design flexibility, and consistency compared to natural stone. A key component in its formulation is the filler material, which constitutes a large percentage of the product’s volume. Kaolin, a fine white clay, is an excellent filler due to its whiteness, chemical inertness, plate-like particle structure, and ability to improve the mechanical properties and surface finish of the final slab.
However, the performance of kaolin as a filler is intrinsically linked to its particle size distribution and purity. Inconsistent or coarse grinding can lead to poor resin binding, reduced strength, visible defects, and unsatisfactory surface polish. Therefore, selecting the right kaolin grinding mill is not just a matter of production capacity; it is a critical decision that impacts product quality, operational efficiency, and profitability. For many growing manufacturers in Bangladesh targeting a production rate of 1 to 3 tons per hour (TPH) of fine kaolin powder, finding a reliable, efficient, and suitably sized grinding solution is paramount.
Grinding kaolin for engineered stone applications presents specific challenges that not all milling equipment can adequately address:
Given the requirements above, traditional solutions like basic Raymond Mills or Ball Mills may fall short. Raymond Mills might struggle to achieve the necessary ultra-fine range efficiently at this capacity, while Ball Mills, though capable, often have higher energy consumption per ton and a larger footprint.
For the Bangladeshi market targeting 1-3 TPH of high-quality kaolin powder, advanced vertical grinding technology and trapezium mills offer a superior balance. As a leading manufacturer in this field, Shanghai Zenith Machinery Co., Ltd. specializes in providing such solutions. Our expertise in ultra-fine powder grinding is backed by decades of research and development, making our equipment ideally suited for demanding mineral processing applications like engineered stone filler production.
Based on the specific needs for fine grinding, system integration, and energy efficiency, we highly recommend the following two models from our product portfolio for engineered stone manufacturers in Bangladesh.
The Zenith XZM Ultrafine Grinding Mill is engineered specifically for producing superfine powders. Its unique grinding chamber design and high-efficiency classifier system make it perfect for processing kaolin to the precise fineness required for high-end engineered stone. It can easily achieve a product size between 325-2500 mesh, ensuring excellent binding and a smooth surface finish in the final slab.
For a 1-3 TPH output, the XZM221 model is an excellent match. Its compact design, combined with powerful performance, offers an ideal solution for medium-scale production.
| Model | Working Diameter (mm) | Max Feed Size (mm) | Final Size (mesh) | Output (kg/h) | Main Motor Power (kW) |
|---|---|---|---|---|---|
| XZM221 | Φ800 | ≤20 | 325-2500 | 500-4500 | 75 |
This model’s output range (500-4500 kg/h) comfortably covers the 1-3 TPH (1000-3000 kg/h) target, providing operational flexibility. Its relatively low power consumption for the output achieved translates to lower operational costs.
For operations that prioritize robust performance, high reliability, and excellent value, the Zenith MTM Medium-Speed Grinding Mill is a top contender. As an advanced successor to the traditional Raymond mill, it features a curved shovel blade that increases grinding efficiency and an improved powder separator for better fineness control. It is perfectly capable of grinding kaolin to the 1.6-0.045mm (approximately 10-325 mesh) range required for most engineered stone formulas.
For your capacity needs, the MTM100 model is highly recommended.
| Model | Ring Roll Number (pcs) | Max. Feed Size (mm) | Output (t/h) | Main Unit Motor Power (kW) |
|---|---|---|---|---|
| MTM100 | 4 | <25 | 3-8 | 37 |
With an output range of 3-8 TPH, the MTM100 can easily meet and exceed the 1-3 TPH target, offering headroom for future expansion. Its significantly lower motor power (37kW) compared to its output makes it one of the most energy-efficient choices in its class for this application.
Selecting Shanghai Zenith Machinery Co., Ltd. goes beyond purchasing a machine; it is a partnership for long-term success. We provide comprehensive support, including:
The quality of engineered stone begins with the quality of its raw materials. Investing in a precise and efficient kaolin grinding system from a reputable manufacturer like Shanghai Zenith is a strategic decision that pays dividends in product excellence, production efficiency, and market competitiveness. For Bangladeshi producers aiming for a 1-3 TPH output of premium kaolin filler, the Zenith XZM221 Ultrafine Grinding Mill and the MTM100 Medium-Speed Grinding Mill present two proven, reliable, and cost-effective pathways to achieving consistent, high-quality powder. By partnering with Zenith, you gain access to world-class grinding technology and the support necessary to optimize your engineered stone production for today’s demanding market.
