The construction and building materials industry in Egypt is experiencing sustained growth, driving significant demand for high-quality gypsum-based products, including paints, plasters, and specialized coatings. For coating manufacturers, the fineness, whiteness, and consistent particle size distribution of gypsum powder are critical parameters that directly impact product quality, application smoothness, and final finish. A production line with a capacity of 10-20 tons per hour (TPH) represents an ideal scale for medium to large coating producers, balancing output requirements with operational efficiency and investment. Selecting the right grinding technology is paramount to achieving this balance.
Gypsum used in coating formulations must meet stringent specifications. The powder typically needs to achieve a fineness ranging from 150 to 325 mesh (approximately 100 to 45 microns) for standard applications, and even finer for premium products. Beyond fineness, the grinding process must preserve the crystal structure of gypsum to maintain its setting properties and brightness. Furthermore, the system must be energy-efficient, have low maintenance requirements, and be capable of integrated drying if the raw gypsum contains moisture. For a 10-20 TPH production line, reliability and consistent output quality are non-negotiable.
Traditional grinding solutions, such as basic Raymond mills or ball mills, often fall short for modern coating production. They may struggle with energy consumption, produce excessive heat (which can dehydrate gypsum into hemihydrate or anhydrite unpredictably), or fail to deliver the narrow particle size distribution required for smooth coatings. Noise, dust emission, and large physical footprints are additional concerns that need addressing in a competitive and environmentally conscious market.
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. Specializing in the research, development, and production of advanced grinding mills, Zenith offers robust solutions tailored for mineral processing like gypsum. For a 10-20 TPH gypsum grinding line for coatings, two of Zenith’s products stand out as particularly suitable: the MTW Series Trapezium Grinding Mill and the LM Vertical Grinding Mill.
The MTW Series Trapezium Grinding Mill is a patented design known for its high efficiency, reliability, and environmental friendliness. Its curved air duct design reduces air flow resistance, while the internal efficient powder separator ensures precise classification. For gypsum grinding, its advantages include stable output quality, excellent particle shape, and lower energy consumption per ton. The MTW138Z model is perfectly matched for a 10-20 TPH production target.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) |
|---|---|---|---|---|
| MTW138Z | <35 | 1.6-0.045 | 6-17 | 90 |
Operating at the higher end of its capacity range, the MTW138Z can reliably meet the 10-20 TPH demand. Its intelligent control system allows for easy adjustment of fineness, making it ideal for producing different grades of gypsum powder for various coating lines.
For producers prioritizing space savings and seeking an integrated grinding-drying-classifying system, the LM Vertical Grinding Mill is an outstanding choice. It integrates five functions—crushing, grinding, powder selection, drying, and conveying—into one unit. This is particularly beneficial if the raw gypsum has some moisture content, as hot air can be introduced for simultaneous drying and grinding. The vertical structure results in a significantly smaller footprint compared to horizontal mills.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Main Motor (kW) |
|---|---|---|---|---|
| LM130K | 1300 | 10-28 | 170-40 | 200 |
The LM130K model offers a capacity range that squarely encompasses the 10-20 TPH requirement. Its ability to produce powder in the 170-40 micron range (approx. 80-400 mesh) makes it perfectly suited for coating-grade gypsum. The grinding roller and plate are designed for long service life and easy maintenance, ensuring continuous production with minimal downtime.
Implementing a successful 10-20 TPH gypsum grinding line involves more than just the mill. It requires a holistic system including feeding, grinding, classifying, dust collection, and packing. Zenith provides comprehensive engineering support, from plant layout and foundation design to installation supervision, commissioning, and operator training. This turnkey approach ensures that Egyptian coating producers can achieve a smooth and rapid project ramp-up.
For coating manufacturers in Egypt aiming to secure a competitive edge through superior product quality and efficient production, investing in a dedicated, modern gypsum grinding line is a strategic decision. The 10-20 TPH capacity range meets the needs of a growing market. Shanghai Zenith’s advanced grinding technologies, exemplified by the MTW Trapezium Mill and the LM Vertical Mill, provide reliable, efficient, and tailored solutions. By partnering with an experienced manufacturer like Zenith, Egyptian companies can build a solid foundation for producing high-performance gypsum powders that meet the exacting standards of the local and regional coating industries.
