The paper-making industry has witnessed a significant transformation over the past decade, driven by the growing demand for eco-friendly and high-quality raw materials. One of the innovative materials now gaining traction in paper production is granite powder. Used as a filler and coating material, ground granite enhances paper durability, brightness, and smoothness. This article provides an in-depth look at the application of granite grinding mills for paper making in Turkey, with a focus on achieving a production capacity of 10–20 TPH (tons per hour). It also introduces suitable grinding solutions offered by Shanghai Zenith Machinery Co., Ltd., a leading manufacturer of industrial powder grinding equipment in China.
Granite, a hard igneous rock, is primarily composed of quartz, feldspar, and mica crystals. When ground into micro or nano-sized powders, these minerals create a filler that improves the brightness, opacity, and printability of paper. In Turkey, one of the largest paper production markets in the Middle East and Europe, the shift towards mineral-filled paper has increased the need for efficient and energy-saving grinding mills capable of processing granite into ultrafine powders.
The target fineness of granite powder for paper-making applications typically ranges from 325 mesh to 1250 mesh, depending on the desired paper quality. To meet this requirement, industrial producers rely on advanced grinding technologies that ensure fine particle size distribution, stable operation, and reduced production costs.
Turkey’s industrial paper producers demand stable, reliable, and high-throughput grinding equipment that can deliver the following performance specifications:
To meet these criteria, advanced grinding mills integrating drying, grinding, classifying, and conveying functions have become the optimal solution. Among them, products by Shanghai Zenith Machinery Co., Ltd. have proven highly suitable for this industrial application.
Shanghai Zenith Machinery Co., Ltd. is a globally recognized manufacturer of industrial grinding and crushing equipment. The company specializes in research, development, and production of powder grinding mills tailored for materials such as ores, minerals, coal, slag, and non-metallic stones including granite. With decades of expertise, Zenith’s products are widely applied in metallurgy, cement, chemical engineering, paper making, and energy sectors.
Notably, Zenith has achieved remarkable success in the field of ultra-fine powder grinding. The company’s MTW Trapezium Grinding Mill and LM Vertical Grinding Mill are particularly well-suited for producing high-quality mineral powders for paper manufacturing.
Considering the requirements for granite grinding for paper making in Turkey, two of Zenith’s mills stand out as optimal solutions: the MTW Trapezium Grinding Mill and the LM Vertical Grinding Mill. Each offers distinct advantages depending on the user’s operational priorities.
The MTW Trapezium Grinding Mill is an advanced grinding equipment developed by Zenith using European technology. It combines traditional Raymond mill principles with innovative system upgrades, making it highly efficient for medium-hard or non-flammable materials like granite. Its precision classifier, smooth transmission system, and integrated design ensure uniform granularity and low energy consumption.
| 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 |
For a 10–20 TPH capacity requirement, the MTW175G model is particularly recommended, as it allows for precise size control and high stability, perfectly suiting medium-level paper-making filler production lines.
Alternatively, the LM Vertical Grinding Mill is ideal for enterprises that require integration of multiple processes, including drying and fine powder selection. It supports continuous production and superior energy efficiency, especially beneficial in humid conditions or for factories looking to reduce operating costs. Furthermore, the vertical layout minimizes floor space and facilitates simplified system maintenance.
| 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 |
| LM190K | 1900 | 23–68 | 170–40 | <45 | 500 |
The LM130K model can achieve 10–28 TPH, making it an excellent choice for medium-sized granite grinding operations in Turkish paper factories. Its integrated grinding-drying-classifying system ensures stable, long-term operation with minimal energy waste.
The general process for producing granite powder for paper fillers involves the following stages:
This workflow guarantees consistent output quality. When using Zenith’s mills, the energy efficiency can improve by up to 30% compared with traditional Raymond mills, while maintenance time is reduced by as much as 50%.
With the rapid advancement of the Turkish paper-making industry, the need for reliable high-capacity grinding solutions is on the rise. The application of MTW Trapezium Grinding Mill and LM Vertical Grinding Mill from Shanghai Zenith Machinery Co., Ltd. provides a robust solution for granite powder processing. These machines combine technical sophistication, operational stability, and environmental protection to deliver maximum profitability for industrial users.
Whether the goal is to produce fine mineral powder for paper filler or to integrate a complete grinding and drying system, Zenith’s technology ensures sustainable operation and consistent product quality. For paper mills and mineral processing enterprises in Turkey targeting 10–20 TPH granite powder production, these solutions offer proven performance and measurable operational efficiency.
Shanghai Zenith Machinery Co., Ltd. remains dedicated to innovation, quality control, and customer satisfaction, establishing itself as a leader in the global mineral grinding industry.
