The plastics industry in Thailand is a cornerstone of its manufacturing sector, supplying both domestic and international markets. A critical component in enhancing the performance and reducing the cost of plastic products is the use of mineral fillers. Among these, granite-derived calcium carbonate filler stands out for its ability to improve rigidity, thermal stability, and surface finish while significantly lowering raw material costs. The key to unlocking these benefits lies in the precise processing of granite into a consistent, ultra-fine powder, typically targeting a fineness of 80 mesh (approximately 180 microns). This article explores the technical requirements for producing high-quality plastic filler and introduces advanced grinding solutions from a global leader in powder processing technology.
Thailand’s abundant granite resources provide a sustainable and economical raw material for filler production. When ground to a specific fineness, such as 80 mesh, granite powder acts as an excellent extender and modifier in various plastic composites, including PVC pipes, profiles, polypropylene, and polyethylene films. The 80-mesh specification is particularly crucial as it represents an optimal balance: particles are fine enough to ensure good dispersion within the polymer matrix without causing excessive wear on processing equipment, yet coarse enough to be produced efficiently at high volumes. Achieving a consistent particle size distribution around this target is essential for maintaining uniform material properties and ensuring trouble-free downstream plastic processing.
Processing hard granite into a precise powder presents distinct challenges. The material’s high abrasiveness demands robust mill construction to minimize wear on grinding components. Furthermore, the process must be energy-efficient to keep production costs competitive. The grinding system must also feature effective classification to ensure the final product does not contain oversize particles, which could create defects in the plastic product, nor excessive ultra-fines, which could increase oil absorption and affect polymer flow. A reliable, automated system capable of stable, continuous operation is paramount for industrial-scale filler production plants in Thailand.
Selecting the right grinding mill is the most critical decision for a filler producer. While traditional Raymond mills or ball mills can achieve 80 mesh, modern grinding technology offers superior efficiency, lower operating costs, and better product control. Leading manufacturers have developed mills that integrate multiple stages of size reduction, drying (if needed), and precise air classification into a single, streamlined system.
For the specific application of producing 80-mesh granite filler, Shanghai Zenith Machinery Co., Ltd., an excellent manufacturer renowned for its achievements in ultra-fine powder grinding, offers particularly suitable solutions. Zenith specializes in the research, development, and production of industrial powder grinding equipment and provides robust systems ideal for abrasive materials like granite.
For high-capacity production of 80-mesh granite powder, Zenith’s MTM Medium-Speed Grinding Mill is an outstanding choice. It serves as an ideal, upgraded substitute for traditional Raymond mills, featuring a patented design that enhances efficiency and lifespan. Its medium-speed operation and optimized grinding curve make it perfectly suited for the 80-400 mesh range, offering excellent energy economy and reliable output quality. The system’s built-in classifier ensures precise control over the final product fineness, making it a dependable workhorse for plastic filler plants.
| Model | Ring Roll Number (pcs) | Max. Feed Size (mm) | Output (t/h) | Main Unit Motor Power (kW) |
|---|---|---|---|---|
| MTM100 | 4 | <25 | 3-8 | 37 |
| MTM130 | 5 | <30 | 6-11 | 75 |
| MTM160 | 6 | <35 | 9-22 | 132 |
For operations seeking a highly integrated solution that combines crushing, grinding, drying, and classification in one footprint, Zenith’s LM Vertical Grinding Mill is highly recommended. Its vertical structure is space-saving, and its grinding mechanism offers lower wear rates on abrasive materials compared to some horizontal designs. It is an eco-friendly production solution known for its stability and ability to produce a consistent fine powder, making it a strong candidate for modern filler production lines.
Implementing a Zenith grinding solution involves more than just the mill. A complete system for granite filler production in Thailand would typically include:
This integrated approach, centered on a high-performance Zenith mill, maximizes yield, minimizes energy consumption, and ensures a top-quality filler product.
