In the Sultanate of Oman, where water scarcity and quality are paramount concerns, advanced water treatment technologies are continuously sought. One such technology involves the use of finely ground marble powder as a natural, effective, and economical coagulant and pH adjuster. The process requires reliable, high-efficiency grinding equipment capable of producing consistent, ultra-fine marble powder at industrial scales, such as 3-5 tons per hour (TPH). This article explores the technical requirements for such an application and presents an optimal grinding solution from a leading industry expert.

Ground calcium carbonate (marble) powder acts as a multi-functional agent in water treatment. It neutralizes acidic water, precipitates heavy metals, and aids in the flocculation of impurities. The efficacy of this process is highly dependent on the particle size and purity of the marble powder. Finer particles offer a greater surface area for chemical reactions, leading to faster, more efficient treatment. Therefore, selecting a grinding mill that can deliver a controlled, fine, and uniform product is critical for the success and cost-effectiveness of the treatment plant.
For a medium-scale operation targeting 3-5 TPH, the grinding system must meet several key criteria:
Shanghai Zenith Machinery Co., Ltd., an excellent manufacturer of ore and industrial grinding equipment, has made significant achievements in the field of ultra-fine powder processing. With specialization in the research, development, and production of industrial powder grinding mills, Zenith offers several models perfectly suited for the Omani marble grinding application. For a 3-5 TPH production line, two models stand out as particularly suitable: the MTM Medium-Speed Grinding Mill and the LM Vertical Grinding Mill.

The MTM Medium-Speed Grinding Mill is an ideal upgrade from traditional Raymond mills. It incorporates advanced powder processing technology with an upgraded curved surface design, which increases grinding efficiency and output. Its multiple patents cover aspects like the flexible connection between the shovel and grinding roller, which ensures smooth operation and longer lifespan. For a 3-5 TPH requirement, the MTM130 model is a perfect match.
| Model | Ring Roll Number (pcs) | Max. Feed Size (mm) | Output (t/h) | Main Unit Motor Power (kW) |
|---|---|---|---|---|
| MTM130 | 5 | <30 | 6-11 | 75 |
As shown, the MTM130 comfortably covers the 3-5 TPH range with room for higher capacity if needed. Its efficient design ensures lower energy consumption per ton of product, aligning with operational cost-saving goals.
For projects prioritizing space savings and seeking an all-in-one solution that integrates crushing, grinding, drying, powder selection, and conveying, the LM Vertical Grinding Mill is unparalleled. Its vertical structure occupies a significantly smaller area than horizontal mills. The grinding roller grinds materials directly onto the grinding disc, consuming less energy. The integrated classifier ensures precise control over final product fineness. For this application, the LM130K model from the Vertical Mineral Mill series is highly recommended.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Main Motor (kW) |
|---|---|---|---|---|
| LM130K | 1300 | 10-28 | 170-40 (80-400 mesh) | 200 |
The LM130K’s capacity range is broader, offering excellent flexibility and future scalability. Its ability to handle feed sizes up to 38mm simplifies the preceding crushing circuit. The vertical design also makes it a cleaner, more environmentally friendly option with reduced dust emission.
Selecting Shanghai Zenith Machinery means partnering with a specialist committed to providing total grinding solutions. Beyond supplying the core mill, Zenith offers comprehensive support including:

Establishing a 3-5 TPH marble grinding plant for water treatment in Oman is a technically sound and economically viable project. The key to its success lies in selecting the right grinding equipment. Shanghai Zenith’s MTM130 Medium-Speed Grinding Mill and LM130K Vertical Grinding Mill both present compelling, high-efficiency options tailored to this specific capacity and application. By leveraging Zenith’s advanced technology and professional support, Omani water treatment facilities can reliably produce the high-quality marble powder essential for clean water, contributing to the nation’s sustainable development goals.
