The ceramic industry in Thailand has experienced remarkable growth over the past decade, becoming a significant contributor to the nation’s manufacturing sector. A key component in high-quality ceramic production is the use of finely ground granite as a filler material, which enhances the structural integrity, thermal stability, and aesthetic appeal of the final product. For medium-scale operations targeting a production capacity of 10 to 20 tons per hour (TPH), selecting the appropriate grinding mill is not just a matter of capacity, but of efficiency, product quality, and long-term operational cost. This article delves into the technical considerations for grinding granite into ceramic-grade powder and explores the ideal machinery solutions for Thai manufacturers.
Granite, an igneous rock composed primarily of quartz, feldspar, and mica, is valued in the ceramic industry for its hardness and chemical inertness. When ground into a fine powder, it acts as a non-plastic material that reduces shrinkage during the drying and firing stages of ceramic production. This results in fewer deformities and cracks, leading to a higher yield of premium-grade ceramic tiles, sanitaryware, and tableware. The desired fineness for this application typically ranges from 170 to 45 microns (100 to 325 mesh), requiring a robust and precise grinding solution.
Grinding granite is an energy-intensive process due to its high Mohs hardness (around 6-7). The abrasive nature of quartz particles can cause rapid wear on grinding components, leading to increased maintenance downtime and contamination of the final product with metal residues. Furthermore, consistent fineness is critical; an inconsistent particle size distribution can lead to defects in the ceramic body. For a 10-20 TPH production line in Thailand’s competitive market, a mill must offer not only the required throughput but also exceptional wear resistance, energy efficiency, and classification accuracy.
Several types of grinding mills can be considered for this application. While traditional Raymond Mills and Ball Mills are common, modern manufacturing demands higher efficiency and lower operational costs. For a 10-20 TPH output of granite powder, vertical roller mills and advanced trapezium mills have emerged as the superior choices. They integrate multiple processes like grinding, drying, and classifying into a single unit, offering a smaller footprint and better control over the final product’s fineness.
For Thai ceramic producers seeking a reliable and efficient solution, Shanghai Zenith Machinery’s MTW Series Trapezium Grinding Mill is highly recommended. This mill is engineered with multiple national patents and is specifically designed for processing medium-hard to hard materials like granite. Its bevel gear overall drive, internal thin oil lubrication system, and arc air channel are standout features that contribute to its high grinding efficiency, stability, and long service life.
For a 10-20 TPH requirement, the MTW175G model is an ideal match. It is designed to handle a maximum feed size of 40mm and can produce a final powder ranging from 1.6mm to 0.045mm, perfectly suited for ceramic filler applications.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) |
|---|---|---|---|---|
| MTW175G | <40 | 1.6-0.045 | 9.5-25 | 160 |
Its capacity of 9.5 to 25 TPH comfortably covers the target production range. The mill’s efficient design also translates to lower energy consumption per ton of output, a crucial factor for managing operational costs in Thailand.
Another excellent option from Shanghai Zenith is the LM Vertical Grinding Mill. This mill is renowned for its compact design and its ability to integrate five functions—crushing, grinding, powder selection, drying, and material conveying—into one unit. This makes it particularly space-efficient, an important consideration for many industrial facilities.
For the specified capacity, the LM190K model is a strong contender. It offers a capacity range that aligns well with the project needs.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Main Motor (kW) |
|---|---|---|---|---|
| LM190K | 1900 | 23-68 | 170-40 | 500 |
While the LM190K has a higher starting capacity, its superior grinding efficiency and lower wear rate on grinding rollers and plates make it a cost-effective solution for high-volume, continuous operations. Its vertical structure also facilitates easier maintenance and inspection.
