The engineered stone industry in Tanzania, encompassing the production of quartz surfaces, countertops, and composite slabs, is experiencing significant growth. This high-value sector demands raw materials of exceptional purity and fineness. Quartz, the primary component, must be ground to a consistent ultra-fine powder, typically targeting 1000 mesh (approximately 13 microns), to ensure the product’s non-porosity, strength, and aesthetic uniformity. Selecting the right grinding technology is paramount to achieving this stringent specification efficiently and profitably.
Engineered stone is a composite material made of approximately 90-95% crushed quartz aggregates bound together with 5-10% polymer resins and pigments. The quality of the final slab is directly influenced by the particle size distribution of the quartz powder. Grinding to 1000 mesh offers several decisive advantages:
Therefore, the grinding mill is not just a size reduction unit but a core component defining product quality and production economics.
Operators in Tanzania face unique challenges. Access to reliable, high-capacity power, the need for robust and low-maintenance machinery, and the requirement for precise particle size control are key considerations. The ideal grinding solution for 1000-mesh quartz must possess:
As an excellent manufacturer of ore and industrial grinding equipment, Shanghai Zenith Machinery Co., Ltd. has made great achievements in the field of ultra-fine powder grinding. Our expertise in research, development, and production of specialized mills provides ideal solutions for the engineered stone industry. For the demanding task of producing 1000-mesh quartz powder in Tanzania, we highly recommend our advanced vertical mill technologies.
For the most efficient and reliable production of 1000-mesh quartz powder, the LUM Ultrafine Vertical Mill stands out as the premier choice. It represents the pinnacle of our ultra-fine grinding technology, integrating grinding, drying, classifying, and conveying into one compact system. Its unique design features multiple grinding rollers and a highly efficient S-classifier, which ensures precise particle size cuts and high yields of product in the desired fineness range.
| Model | Main Machine Power (kW) | Capacity (t/h)* | Size Distribution D97 (μm) | Approx. Equivalent Mesh |
|---|---|---|---|---|
| LUM1525 | 220-250 | 1.6 – 11.5 | 5 – 30 | 2500 – 500 mesh |
| LUM1632 | 280-315 | 2.0 – 13.5 | 5 – 30 | 2500 – 500 mesh |
| LUM1836 | 355-400 | 2.3 – 15.0 | 5 – 30 | 2500 – 500 mesh |
*Capacity varies based on material hardness and required fineness. For 1000 mesh (~13 μm D97), the LUM series can be precisely configured to achieve optimal output.
Why the LUM is Ideal for Tanzania: Its intelligent control system allows for stable operation with less skilled labor, its compact footprint saves valuable plant space, and its high grinding efficiency translates to lower energy consumption per ton of product—a critical factor for cost-sensitive operations.
For projects with slightly different capacity requirements or budget considerations, the XZM Ultrafine Grinding Mill is another proven workhorse from Zenith’s portfolio. It is widely used for superfine powder production and is perfectly capable of achieving an output fineness of 325-2500 mesh, comfortably covering the 1000-mesh target.
| 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 |
| XZM268 | Φ1680 | ≤20 | 325-2500 | 5000 – 25000 | 315 |
*Output is highly dependent on material properties and target fineness.
Advantages of the XZM Mill: It offers a robust and straightforward design known for reliable performance with minimal maintenance. Its ability to handle materials with moisture content below 6% with optional hot air intake makes it a versatile and cost-effective solution for many quartz processing plants in Tanzania.
The future of Tanzania’s engineered stone industry is bright, and its competitiveness on the global stage will be underpinned by the quality of its raw materials. Investing in the correct ultra-fine grinding technology is a strategic decision. Shanghai Zenith Machinery Co., Ltd., with its comprehensive range of grinding equipment like the high-performance LUM Ultrafine Vertical Mill and the reliable XZM Ultrafine Grinding Mill, is positioned to be a key partner in this journey.
