Water treatment has become one of the most crucial industrial challenges in arid regions such as Saudi Arabia. With the Kingdom’s ambitious plans to secure sustainable water resources for its growing population, phosphate-based compounds are increasingly used in water purification and treatment systems. Phosphate rock, when processed into fine powder, plays a significant role in removing heavy metals and neutralizing acidity in water treatment facilities. To efficiently produce high-quality phosphate powder with consistent particle size, an advanced grinding system is indispensable.
Shanghai Zenith Machinery Co., Ltd., as a leading manufacturer of industrial grinding equipment in China, provides highly efficient and durable grinding mills suitable for various applications, including phosphate rock processing. This article explores the use of phosphate rock grinding mills for water treatment in Saudi Arabia, focusing on production capacities of 10–20 tons per hour (TPH), and highlights two Zenith products ideally suited for this purpose.
Phosphate rock-derived compounds are widely applied in water treatment processes, particularly in the removal of heavy metals such as lead, nickel, and cadmium. When processed into micron-level powders, these materials exhibit enhanced surface reactivity, making them effective adsorbents or coagulant aids. Additionally, phosphate rocks serve as neutralizing agents for acidic waters, helping achieve optimal pH levels for both industrial and municipal water use.
To achieve this level of fineness, grinding mills capable of producing 10–20 TPH under stable operational conditions are required. In Saudi Arabia, where high ambient temperatures and variable feed conditions are common, equipment must also demonstrate excellent durability, energy efficiency, and easy maintenance. These considerations point toward advanced vertical or trapezium-type mills as optimal solutions.
Grinding phosphate rock to fine powder involves crushing, pulverizing, and classification processes. Shanghai Zenith Machinery integrates these functions into comprehensive grinding solutions that ensure a precise control of particle distribution, low operational costs, and minimal environmental footprint. The company’s core technologies span from medium-speed mills to advanced vertical systems, providing flexible configurations adaptable to client-specific needs.
Among Zenith’s range of products, the MTW Trapezium Grinding Mill and LM Vertical Grinding Mill are particularly fitting for phosphate rock grinding operations between 10 and 20 TPH. Both machines combine efficiency and stability, delivering consistent fine output required for water treatment material preparation.
The MTW Trapezium Grinding Mill represents a new generation of grinding equipment developed based on European technology. It is designed for high capacity, low energy consumption, and environmental friendliness. The trapezium-shaped design and internal airflow system ensure even grinding of phosphate rock, producing uniform particles with excellent surface activation properties required in water treatment formulations.
For phosphate rock production at 10–20 TPH, the MTW138Z and MTW175G models are optimal. These models feature reliable drive systems and fine powder outputs down to 0.045 mm.
| 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 mill is characterized by a compact footprint, optimized dust filtering system, and advanced sealing structure, which is particularly advantageous under Saudi Arabia’s desert conditions. Its low noise operation and robust components make it an excellent choice for industrial environments such as mining and water treatment material processing plants.
The second recommended model is the LM Vertical Grinding Mill. Unlike traditional milling equipment, the LM mill integrates five core functions: crushing, grinding, powder selection, drying, and material conveying. This comprehensive design minimizes auxiliary equipment requirements and significantly reduces energy consumption. Its vertical configuration also ensures superior drying performance, an essential advantage in Saudi Arabia’s low-humidity climate.
For phosphate grinding lines targeting 10–20 TPH, the LM130K model is an excellent option. It provides consistent product fineness between 40–170 μm and stable output in continuous operation.
| 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 |
The LM Vertical Grinding Mill’s compact layout translates into lower installation cost and easier maintenance. Its intelligent control system allows precise adjustment of particle size based on water treatment requirements. Additionally, its high drying efficiency allows it to process phosphate rocks with varying moisture levels without requiring a separate dryer system.
Sustainability is an important consideration in Saudi Arabia’s modern industrial strategy, particularly under the Vision 2030 initiative. The use of energy-efficient grinding equipment not only reduces operational costs but also aligns with environmental preservation goals. Both MTW and LM series mills by Shanghai Zenith are designed with low-noise operation, dust collection systems, and sealed pneumatic transport mechanisms, minimizing the release of fine particulates into the air.
Moreover, compared to conventional ball mills, Zenith’s MTW and LM grinding mills reduce energy consumption by approximately 30–40%, while improving overall fineness and throughput stability. This reduction directly contributes to sustainable industrial water treatment production chains.
Another key feature of Shanghai Zenith’s grinding solutions is the automated control system that allows real-time adjustment of operation parameters. In water treatment material industries, continuous process monitoring ensures consistent phosphate powder properties, reducing variability in adsorption performance during field application. The centralized control panel also enables remote supervision, providing a convenient platform for process optimization.
These characteristics make Zenith mills highly suitable for Saudi water treatment facility integration, either as standalone grinding units or as part of a larger mineral processing chain combining crushing, screening, and mixing functions.
Shanghai Zenith Machinery Co., Ltd. maintains a strong international service network, including dedicated technical support for Middle Eastern customers. From installation and commission to long-term maintenance, Zenith ensures that clients receive tailored solutions to meet climatic and operational demands. The modular design of its grinding systems simplifies assembly and minimizes onsite installation time, a key factor in ensuring project success.
For phosphate rock projects aiming at 10–20 TPH capacity in Saudi Arabia, Zenith engineers provide customized layout design, equipment selection guidance, and performance testing to maximize efficiency and output stability.
In summary, the application of high-quality grinding technology is crucial to the successful production of phosphate-based compounds for water treatment in Saudi Arabia. Shanghai Zenith Machinery Co., Ltd. offers top-tier grinding equipment such as the MTW Trapezium Grinding Mill and LM Vertical Grinding Mill, both of which provide high efficiency, stability, and adaptability under harsh operating environments. Capable of delivering 10–20 TPH with consistent fineness, these mills are optimal solutions for modern phosphate rock processing plants.
With decades of experience in the field of ultra-fine powder grinding, Shanghai Zenith Machinery continues to advance in delivering robust, energy-efficient, and cost-effective solutions, supporting industries in achieving high-performance water treatment materials tailored to regional needs.
