Turkey has emerged as a significant player in the global paper and pulp industry, with its production capacity steadily increasing over the past decade. The country’s paper mills, particularly those located in the Marmara and Aegean regions, rely heavily on cost-effective energy sources to maintain competitiveness. Petroleum coke (petcoke), a by-product of oil refining, has become a preferred fuel for industrial boilers and lime kilns in paper manufacturing due to its high calorific value (typically 8,000–8,500 kcal/kg) and lower cost compared to natural gas or heavy fuel oil. However, to achieve efficient combustion and minimize emissions, petcoke must be finely ground to a specific particle size distribution—usually 200 mesh (75 μm) or finer—before being injected into burners. This makes the selection of a reliable, high-capacity grinding mill a critical decision for Turkish paper producers targeting a throughput of 20–30 tons per hour.
Petroleum coke is a hard, brittle carbonaceous material with a Mohs hardness of around 2–3, but it also exhibits high abrasiveness due to its low volatile content and high fixed carbon. Traditional grinding equipment often suffers from excessive wear, high energy consumption, and unstable product fineness when processing petcoke. Moreover, paper mills require consistent operation with minimal downtime, as any interruption in fuel preparation can lead to costly production stoppages. Therefore, a grinding mill designed for heavy-duty industrial applications with advanced wear protection, high efficiency, and intelligent control is essential.
Shanghai Zenith Machinery Co., Ltd. is an excellent manufacturer of ore grinding equipment in China, with extensive experience in the field of ultra-fine powder grinding. The company specializes in the research, development, and production of industrial powder grinding equipment and related devices. Its product portfolio includes MTW Trapezium Grinding Mill, Ball Mill, MTM Medium-Speed Grinding Mill, Raymond Mill, LM Vertical Grinding Mill, LUM Ultrafine Vertical Mill, XZM Ultrafine Grinding Mill, and Hammer Mill. For the specific application of petroleum coke grinding in Turkish paper mills with a capacity of 20–30 t/h, Zenith offers two outstanding solutions: the MTW215G Trapezium Grinding Mill and the LM190K Vertical Grinding Mill. Both machines are engineered to deliver high throughput, fine product quality, and long service life under demanding conditions.
The MTW series is a flagship product of Zenith, featuring multiple international patents. The MTW215G model is the largest in the series, designed for high-capacity applications. Its trapezoidal grinding roller and ring design create a multi-stage grinding effect that efficiently breaks down petcoke particles while reducing energy consumption. The mill incorporates an internal classifier with a high-efficiency impeller, allowing precise control of product fineness (adjustable from 80 mesh to 325 mesh). For paper mills needing 20–30 t/h of petroleum coke at around 200 mesh (75 μm), the MTW215G is an ideal choice. Its compact structure, automatic lubrication system, and sealed gearbox ensure minimal maintenance and maximum uptime. Below are the key technical parameters:
| Parameter | MTW215G |
|---|---|
| Max. Feed Size (mm) | ＜50 |
| Final Product Size (mm) | 1.6–0.045 (10–325 mesh) |
| Capacity (t/h) | 15–45 |
| Main Motor Power (kW) | 280 |
| Fan Motor Power (kW) | 315 |
| Classifier Speed (r/min) | Adjustable by inverter |
| Total Weight (t) | ≈ 62 |
The MTW215G is particularly suitable for Turkish paper mills that prefer a traditional roller mill design with proven reliability. Its ability to handle feed sizes up to 50 mm reduces the need for secondary crushing, saving both capital and operational costs.
For paper manufacturers seeking a more integrated and space-saving solution, the LM190K Vertical Grinding Mill offers exceptional advantages. The LM series combines crushing, grinding, drying, and powder selection in a single unit, dramatically reducing the plant footprint. Its vertical configuration uses a rotating grinding table and stationary rollers to grind material by compression and shear. The LM190K is equipped with a high-efficiency dynamic classifier that ensures a steep particle size distribution, critical for consistent petcoke combustion. With a production capacity of 23–68 t/h, it comfortably covers the 20–30 t/h requirement while leaving room for future capacity expansion. The mill also features an automatic control system that adjusts feed rate, grinding pressure, and classifier speed in real time, ensuring stable operation even when petcoke quality varies.
| Parameter | LM190K |
|---|---|
| Plate Diameter (mm) | 1900 |
| Capacity (t/h) | 23–68 |
| Output Fineness (μm) | 170–40 (80–400 mesh) |
| Max Feed Size (mm) | ＜45 |
| Main Motor Power (kW) | 500 |
| Classifier Type | High-efficiency dynamic |
| Drying Capability | Yes (hot gas from kiln can be used) |
The LM190K is an excellent choice for Turkish paper mills that value low noise, low vibration, and the ability to integrate drying with grinding—especially when petcoke has residual moisture from storage. Its vertical design also simplifies maintenance, as the grinding rollers can be flipped or replaced without dismantling the entire mill.
Both the MTW215G and LM190K are capable of meeting the 20–30 t/h requirement for petroleum coke grinding in Turkish paper mills. The choice largely depends on the customer’s existing infrastructure, available space, and preference for maintenance procedures. The MTW215G offers a lower initial investment and simpler operation for operators familiar with traditional roller mills. In contrast, the LM190K provides higher integration—combining drying, grinding, and classification—and delivers a narrower particle size distribution, which can improve combustion efficiency and reduce NOx emissions. Additionally, the LM series’ dynamic classifier can be fine-tuned to produce ultra-fine fractions (down to 40 μm) if the mill later needs to switch to other materials such as coal or biomass.
As Turkey’s paper industry continues to expand, the demand for reliable, high-capacity petroleum coke grinding solutions will only grow. Shanghai Zenith Machinery, with its decades of expertise and comprehensive product range, stands ready to support Turkish producers in optimizing their fuel preparation processes. Whether you choose the MTW215G Trapezium Grinding Mill or the LM190K Vertical Grinding Mill, you will benefit from robust construction, advanced automation, and proven performance in grinding abrasive materials like petcoke.
