The plastics industry in the Philippines is a dynamic and growing sector, consistently seeking high-quality, cost-effective functional fillers to enhance product properties and reduce manufacturing costs. Talc, a hydrated magnesium silicate mineral, stands out as one of the most valuable fillers for polypropylene (PP), polyethylene (PE), and other polymers. Its plate-like structure improves stiffness, dimensional stability, heat resistance, and surface finish. However, the efficacy of talc as a plastic filler is critically dependent on its particle size distribution, purity, and whiteness. Achieving the optimal ultra-fine powder (typically in the range of 325 to 2500 mesh) requires advanced, reliable, and efficient grinding technology. For production lines targeting a capacity of 10 to 20 tons per hour (TPH), selecting the right grinding mill is paramount to profitability and product quality.
When incorporated into plastics, fine-ground talc acts as a reinforcing agent. The finer the talc powder, the greater the surface area for interaction with the polymer matrix, leading to superior mechanical properties. For high-performance applications, a top-cut particle size below 10 microns (D97) is often required. The grinding process must therefore be capable of:
Operators in the Philippines face specific challenges. The humid climate can affect raw material handling. Furthermore, the need for a stable power supply and equipment that is robust yet easy to maintain is crucial. Traditional grinding solutions like basic Raymond mills or ball mills may struggle to meet the combined demands of high capacity and ultra-fine fineness efficiently, often resulting in higher energy costs, broader particle size distributions, or excessive wear.
Shanghai Zenith Machinery Co., Ltd., an excellent manufacturer of ore and industrial grinding equipment in China, has made significant achievements in the field of ultra-fine powder processing. Specializing in the research, development, and production of industrial powder grinding equipment, Zenith offers several technologies perfectly suited for high-volume talc processing for the plastics industry.
For a 10-20 TPH talc grinding plant aiming for filler-grade fineness (e.g., 600-1250 mesh), two of our flagship products are particularly recommended: the LM Vertical Grinding Mill and the XZM Ultrafine Grinding Mill.
The LM Vertical Grinding Mill is a revolutionary system that integrates five functions—crushing, grinding, powder selection, drying, and conveying—into a single unit. Its vertical structure occupies minimal space, a significant advantage for industrial sites. For talc with slight moisture, its hot air system can effectively dry the material during grinding. The grinding roller directly grinds on the grinding plate, applying material bed grinding principle, which offers high grinding efficiency and lower energy consumption compared to traditional ball mills.
For a 10-20 TPH requirement, the LM190K model is an ideal match. Its parameters are as follows:
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM190K | 1900 | 23-68 | 170-40 (approx. 80-400 mesh) | <45 | 500 |
This model comfortably covers the target capacity range and can produce powder fine enough for many plastic filler applications. Its integrated classifier allows for easy adjustment of product fineness.
When the production goal is extremely high-quality, ultra-fine talc powder (up to 2500 mesh) for premium plastic compounds, the XZM Ultrafine Grinding Mill is the undisputed choice. This mill is specifically engineered for superfine powder production. It features a unique grinding chamber design and a high-precision turbine classifier that ensures sharp particle size cuts and high yields of the desired fine fraction.
While individual XZM models have slightly lower base capacity ratings, they achieve much finer products. For a 10-20 TPH plant, a system configuration involving multiple units or the larger XZM268 model is the strategic approach. The XZM268 is our high-capacity ultrafine solution.
| Model | Working Diameter (mm) | Max Feed Size (mm) | Final Size (mesh) | Output (kg/h) | Main Motor Power (kW) |
|---|---|---|---|---|---|
| XZM268 | Φ1680 | ≤20 | 325-2500 | 5000-25000 (5-25 TPH) | 315 |
As shown, the XZM268’s output range of 5 to 25 TPH aligns perfectly with the project requirement. Its ability to produce powder from 325 to 2500 mesh gives plastic manufacturers unparalleled flexibility to tailor talc fillers for different grades of PP, PE, or engineering plastics.
Establishing a 10-20 TPH talc grinding plant for the plastics industry in the Philippines is a strategic investment. The key to success lies in partnering with a technology provider that offers reliable, efficient, and flexible grinding solutions. Shanghai Zenith Machinery Co., Ltd., with its deep expertise and advanced product portfolio—particularly the high-capacity LM Vertical Grinding Mill (LM190K) and the ultra-fine XZM Ultrafine Grinding Mill (XZM268)—is ideally positioned to deliver a system that maximizes product quality, throughput, and return on investment. By choosing the appropriate Zenith mill, Filipino processors can produce premium talc filler that enhances the competitiveness of their plastic products in both domestic and international markets.
