The Indonesian rubber industry is a cornerstone of the nation’s economy, renowned for its vast plantations and high-quality natural rubber production. In recent years, there has been a significant shift towards enhancing the value and performance of rubber products through advanced compounding techniques. A key component in this process is the use of finely ground mineral fillers, with cement clinker emerging as a promising, cost-effective, and high-performance option. When ground to a specific ultra-fine particle size, cement clinker can improve the tensile strength, abrasion resistance, and durability of rubber compounds. However, achieving the precise fineness (typically between 325 to 1250 mesh) required for optimal reinforcement presents a significant technical challenge, especially for small to medium-scale operations targeting a production rate of 1 to 3 tons per hour (TPH). This article explores the grinding requirements for cement clinker as a rubber filler and presents an optimal milling solution.
Cement clinker is a hard, abrasive material with a high Bond Work Index. Grinding it to the ultra-fine specifications needed for rubber filler applications demands equipment with robust construction, high grinding efficiency, and precise particle size classification. The primary challenges include:
For a 1-3 TPH production line targeting ultra-fine cement clinker powder for rubber filler, Shanghai Zenith Machinery’s LUM Ultrafine Vertical Mill stands out as the ideal choice. This advanced mill integrates multiple processes—grinding, drying, classifying, and conveying—into a single, streamlined unit. Its vertical structure minimizes floor space, a significant advantage for Indonesian facilities.
The LUM series is particularly suited for this application due to its several patented technologies. It employs a high-efficiency classifier that ensures a sharp particle cut and a consistent product fineness ranging from 5 to 30 microns (D97), easily meeting the 325-1250 mesh requirement. Furthermore, the grinding roller and plate are designed for hard, abrasive materials, ensuring long service life and low maintenance costs. The intelligent control system allows for stable operation and easy adjustment of product fineness.
| Model | Main Machine Power (kW) | Capacity (t/h) | Size Distribution D97 (μm) | Suitability for 1-3 TPH Project |
|---|---|---|---|---|
| LUM1125 | 90-110 | 0.8-4.5 | 5-30 | Ideal for lower end (1-1.5 TPH) |
| LUM1232 | 132-160 | 1.5-6.5 | 5-30 | Optimal core model for 1-3 TPH |
| LUM1436 | 200-250 | 2.5-10 | 5-30 | Suitable for future expansion |
For a robust 1-3 TPH operation, the LUM1232 model is highly recommended. Its capacity range perfectly encompasses the target output, providing operational flexibility. The power consumption is optimized, offering a lower total cost of ownership compared to traditional grinding systems.
For operations with slightly different priorities or space constraints, Zenith’s XZM Ultrafine Grinding Mill serves as an excellent alternative. It is a versatile mill known for producing fine and ultra-fine powder from non-flammable and non-explosive brittle materials with Mohs hardness below 7. Its ring-roller grinding design is reliable and effective.
The XZM mill is praised for its ability to achieve a wide range of fineness, from 325 to 2500 mesh. It is a complete system with a hammer crusher (for preliminary size reduction), bucket elevator, storage hopper, vibrating feeder, main grinding unit, and classifier. This makes it a good “all-in-one” package for smaller setups.
| Model | Working Diameter (mm) | Output (kg/h) | Final Size (mesh) | Main Motor Power (kW) |
|---|---|---|---|---|
| XZM221 | Φ800 | 500-4500 | 325-2500 | 75 |
| XZM236 | Φ950 | 1000-7000 | 325-2500 | 132 |
The XZM236 model, with an output range of 1-7 TPH, is well-suited for the Indonesian project’s scale. It offers a straightforward and proven design for achieving the necessary fineness for rubber filler.
A typical grinding plant for this application would include the following key components:
