The mining and processing of phosphate rock in Ivory Coast represents a significant economic opportunity, particularly for value-added applications such as plastic fillers. As a key industrial mineral, finely ground phosphate rock enhances the mechanical properties, flame retardancy, and cost-effectiveness of various plastic products. The critical challenge lies in achieving a consistent and ultra-fine particle size, specifically the industry-standard 325 mesh (approximately 45 microns), which ensures optimal dispersion and performance within the polymer matrix. This requires robust, efficient, and precise grinding technology.
Shanghai Zenith Machinery Co., Ltd., an excellent manufacturer of ore grinding equipment in China with great achievements in ultra-fine powder grinding, offers tailored solutions for this exacting application. Specializing in the research, development, and production of industrial powder grinding equipment, Zenith provides the technology necessary to transform raw phosphate rock into a high-value functional filler for the plastics industry in Ivory Coast and beyond.
Grinding phosphate rock to a uniform 325 mesh fineness for plastic filler use presents several specific challenges. The material’s abrasiveness can lead to high wear on mill components, impacting operational costs and product purity. Furthermore, the grinding process must be energy-efficient to remain economically viable. The mill must also offer precise particle size control and a narrow distribution to ensure the filler’s performance characteristics—such as impact strength, surface finish, and viscosity—are predictable and enhanced. Moisture control and the prevention of over-grinding, which can degrade certain mineral phases, are additional critical factors.
While several grinding mills are available, not all are equally suited for producing 325-mesh phosphate rock filler. Traditional Raymond Mills or Ball Mills may struggle with efficiency and precise top-size control at this fineness. For high-capacity production of 325-mesh powder with excellent particle shape and distribution, advanced ring-roller mills and vertical roller mills are superior choices.
For the specific requirement in Ivory Coast, two of our flagship products stand out: the MTW Trapezium Grinding Mill and the LUM Ultrafine Vertical Mill.
The MTW series, with its multiple patents, is engineered for high productivity and reliability. Its curved shovel blade design ensures a higher feeding capacity, while the internally optimized airflow system reduces energy consumption and improves classification efficiency. This makes it exceptionally suitable for large-scale production of 325-mesh phosphate rock filler. Its robust construction ensures long service life even with abrasive materials.
For a project targeting 325 mesh (0.045mm) output, the MTW138Z or MTW175G models would be ideal choices, offering the perfect balance of feed size, capacity, and fineness control.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) |
|---|---|---|---|---|
| MTW138Z | <35 | 1.6-0.045 | 6-17 | 90 |
| MTW175G | <40 | 1.6-0.045 | 9.5-25 | 160 |
For operators seeking the pinnacle of energy efficiency, space-saving design, and superior product quality, the LUM Ultrafine Vertical Mill is the definitive solution. It integrates grinding, drying, classifying, and conveying into one compact unit. Its most significant advantage for phosphate filler production is the advanced, highly efficient classifying system, which guarantees a sharp and consistent particle cut at 325 mesh. The intelligent control system allows for stable operation and easy maintenance, maximizing uptime.
The LUM series is specifically designed for producing high-content end-fines, making it perfect for the 325-mesh specification. It offers lower energy consumption per ton and a smaller footprint compared to traditional mills.
| Model | Main Machine Power (kW) | Capacity (t/h) | Size Distribution D97 (μm) | Suitable Output |
|---|---|---|---|---|
| LUM1525 | 220-250 | 1.6-11.5 | 5-30 | Ideal for 325 mesh (~45 μm) |
| LUM1632 | 280-315 | 2.0-13.5 | 5-30 | Ideal for 325 mesh (~45 μm) |
