Phosphate rock is an indispensable raw material in multiple industries, including agriculture, metallurgy, and chemical manufacturing. In recent years, the utilization of phosphate rock in the rubber industry as a filler has attracted growing attention due to its reinforcing capability, cost efficiency, and environmental benefits. In Zambia, where phosphate rock deposits are relatively abundant, the demand for high-efficiency grinding equipment suitable for producing fine phosphate powder (3–5 TPH capacity) is increasing rapidly.
Shanghai Zenith Machinery Co., Ltd., a leading Chinese manufacturer specializing in the development of industrial grinding mills, provides advanced technology and high-efficiency equipment specifically designed for phosphate rock processing. This article introduces the key considerations in phosphate rock grinding for rubber filler applications in Zambia and recommends suitable equipment models from Shanghai Zenith Machinery Co., Ltd..
The use of phosphate rock as a rubber filler improves the mechanical performance of rubber products by enhancing their tensile strength, durability, and wear resistance. Its fine particle size also allows better dispersion within the polymer matrix. Moreover, substituting part of traditional mineral fillers such as calcium carbonate or silica with phosphate rock can result in significant cost savings and sustainability benefits for local rubber manufacturing companies in Zambia.
However, to ensure the phosphate rock meets the required particle size distribution (typically 325–600 mesh) for filler applications, precise and consistent grinding performance is essential. Therefore, selecting the right grinding mill is the critical first step.
Phosphate rock is typically of medium hardness and abrasive nature, which poses specific challenges in the grinding process:
For phosphate rock grinding at a production rate of 3–5 tons per hour, Shanghai Zenith Machinery Co., Ltd. offers several suitable models that deliver high efficiency, stable output, and fine product quality. Two noteworthy options include the MTW Trapezium Grinding Mill and the LM Vertical Grinding Mill.
The MTW Trapezium Grinding Mill is a high-performance grinding system designed with advanced European technology. It integrates grinding, classification, powder conveying, and collection. Its efficient air circulation system and adjustable classifier ensure controlled particle size and high product consistency — ideal for phosphate rock used as a rubber filler.
For a target capacity of 3–5 TPH in Zambia, the MTW110 model offers optimal balance between energy consumption and production output.
| 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 |
Recommended for phosphate rock grinding in Zambia for rubber filler production.
The LM Vertical Grinding Mill integrates crushing, grinding, classification, drying, and transporting functions in one compact unit. It provides a stable and intelligent solution for fine powder processing with a small footprint and low energy consumption. The LM130N and LM130X-GX models, depending on the desired fineness and production stability, are suitable for the 3–5 TPH phosphate grinding line.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM130N | 1300 | 4–6 | 170–40 | <38 | 200–250 |
| LM130X-GX | 1300 | 4–12 | 325–600 mesh | <38 | 220 |
The LM Vertical Mill’s design allows effective drying of phosphate rock with small moisture content before grinding, making it a perfect choice for Zambian operations located in varying humidity environments.
To achieve consistent product quality, the processing workflow typically includes the following stages:
