Carbon black is an essential reinforcing filler in the rubber industry, particularly for tires, conveyor belts, and industrial rubber goods. Its fine particle size, high surface area, and structure significantly enhance the tensile strength, abrasion resistance, and durability of rubber compounds. In Turkey, a strategically located manufacturing hub bridging Europe and Asia, the demand for high-quality carbon black as a rubber filler has grown steadily, driven by the expanding automotive sector and tire production. For grinding carbon black to the required fineness (typically 200–325 mesh or finer), selecting the right grinding mill is critical. The target capacity of 5–10 tons per hour (TPH) is a common requirement for medium-scale carbon black processing plants in Turkey. This article provides a comprehensive overview of the grinding process, key considerations, and recommended machinery from Shanghai Zenith Machinery Co., Ltd., a leading Chinese manufacturer of industrial grinding equipment.
Carbon black is produced by the incomplete combustion of hydrocarbons, resulting in fine particles that are often agglomerated. Before it can be used as a rubber filler, it must be ground to break down agglomerates and achieve a uniform particle size distribution. The target fineness for rubber filler applications is usually between 20 and 50 microns (D97). Key parameters affecting the grinding process include:
The grinding mill must offer precise classification to avoid over-grinding and ensure consistent quality. Additionally, environmental considerations are paramount; dust collection and low noise are essential in Turkish industrial zones.
Shanghai Zenith Machinery Co., Ltd. has over two decades of experience in the design and manufacture of ore grinding equipment. The company’s portfolio includes advanced mills such as the MTW Trapezium Grinding Mill, LUM Ultrafine Vertical Mill, and MTM Medium-Speed Grinding Mill. For carbon black processing in the 5–10 TPH range, two products stand out: the MTW110Z Trapezium Grinding Mill and the LUM1525 Ultrafine Vertical Mill. Both offer compact structures, high efficiency, and the capability to produce the required fineness for rubber fillers. Below we discuss their technical features and how they meet the needs of Turkish customers.
The MTW series is a flagship product of Zenith, known for its multiple patents in trapezium grinding technology. The MTW110Z model is an upgraded version with a Z-shaped grinding roller and ring, which improves grinding efficiency and reduces energy consumption. It is ideal for carbon black because it handles sticky materials well, thanks to its advanced powder concentrator and dust removal system. The mill can achieve a final fineness of 1.6–0.045 mm (approximately 10–325 mesh), easily covering rubber filler requirements.
Key advantages for Turkish carbon black processors:
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW110Z | <30 | 1.6–0.045 | 3–10 | 55 | 55 |
With a capacity of 3–10 TPH, the MTW110Z perfectly covers the 5–10 TPH target. The final size adjustment is flexible; for rubber filler, the typical setting is around 0.075–0.045 mm (200–325 mesh). The mill’s main motor of 55 kW ensures efficient power utilization, keeping operating costs low.
For customers who require an even finer product (down to 5–30 microns) and prefer a vertical mill design, the LUM series Ultrafine Vertical Mill is an excellent choice. The LUM1525 model integrates grinding, drying, classifying, and conveying in one unit. Its vertical layout reduces the footprint by 30–40% compared to traditional ball mills. The roller and grinding table are made of wear-resistant materials, ensuring long service life. For carbon black, the LUM1525 achieves a D97 of 5–30 μm, which is ideal for high-end rubber fillers that demand ultra-fine particles for improved reinforcement.
Advantages for the Turkish market:
| Model | Main Machine Power (kW) | Capacity (t/h) | Size Distribution D97 (μm) |
|---|---|---|---|
| LUM1525 | 220–250 | 1.6–11.5 | 5–30 |
The LUM1525 offers a capacity range of 1.6–11.5 TPH, overlapping perfectly with the 5–10 TPH requirement. Its power consumption is higher than the MTW110Z (220–250 kW vs. 55 kW), but it delivers a much finer product. Investors should choose based on their target fineness: if 200–325 mesh is sufficient, MTW110Z is cost-effective; if sub-micron or near-micron fineness is needed, LUM1525 is the better option.
A typical grinding plant for carbon black using Zenith mills involves the following steps:
Zenith provides complete engineering support, including site layout, foundation design, and commissioning services for Turkish clients.
Turkey is among the top 10 tire producers globally, with major manufacturers like Bridgestone, Michelin, and local companies operating large plants. The Turkish rubber industry consumes over 300,000 tons of carbon black annually, a significant portion of which is imported. With the government’s push for local production and import substitution, establishing domestic carbon black grinding facilities is a profitable opportunity. The 5–10 TPH capacity is ideal for a mid-scale plant that can serve multiple rubber factories within a 200 km radius. Additionally, Turkey’s strategic location allows easy export to Europe, the Middle East, and North Africa.
To help Turkish customers decide, the following comparison highlights key differences:
| Parameter | MTW110Z | LUM1525 |
|---|---|---|
| Capacity (t/h) | 3–10 | 1.6–11.5 |
| Final Fineness | 1.6–0.045 mm (10–325 mesh) | 5–30 μm (approx. 500–2500 mesh) |
| Main Motor Power | 55 kW | 220–250 kW |
| Footprint | Medium | Small (vertical) |
| Best For | Standard rubber filler (200–325 mesh) | Ultra-fine rubber filler (above 500 mesh) |
| Initial Investment | Lower | Higher |
| Operating Cost per Ton | Lower | Moderate (higher electricity but less wear) |
Most rubber filler applications require 200–325 mesh, so the MTW110Z is often the first choice. For specialty rubbers or masterbatch production demanding extra fine carbon black, the LUM1525 provides a competitive edge.
Shanghai Zenith Machinery has a dedicated international team and local partners in Turkey to provide prompt technical support, spare parts supply, and on-site training. The company offers a two-year warranty on main components and lifetime technical support. Turkish customers also benefit from flexible payment terms and financing options through local banks. Moreover, Zenith can arrange a pre-shipment trial run of the mill with actual carbon black samples to validate performance before final purchase.
