Indonesia’s rapidly expanding industrial sector, particularly in paints, coatings, and anode production, has created a significant demand for high-quality, finely ground petroleum coke (petcoke). As a key filler and conductive agent, petcoke’s performance is heavily dependent on its particle size distribution, fineness, and purity. For production lines targeting a capacity of 1 to 3 tons per hour (TPH), selecting the right grinding technology is paramount to achieving consistent product quality, operational efficiency, and cost-effectiveness. This article explores the specific requirements for petcoke grinding in coating applications and presents an optimal milling solution.
Petroleum coke, a carbonaceous solid derived from oil refinery coker units, presents unique challenges for grinding. Its characteristics vary from soft to moderately hard, and it often contains volatile components. For coating production, the material must be ground to a very fine powder, typically ranging from 200 to 800 mesh (D97). The grinding process must ensure:
For the 1-3 TPH capacity range in Indonesia’s coating industry, traditional solutions like Raymond mills may lack the necessary fineness control, while ball mills can be less energy-efficient for ultra-fine grinding. The most advanced and suitable technology is the Vertical Grinding Mill. This system integrates multiple processes—drying (if needed), grinding, classification, and conveying—into a single, space-saving unit.

Vertical mills operate on the principle of bed grinding between rollers and a rotating table, which is highly efficient. An integrated dynamic classifier immediately separates fine particles from coarse ones, sending the coarse material back for regrinding. This closed-circuit system ensures a consistent, narrow particle size distribution, which is ideal for coating-grade petcoke.
Shanghai Zenith Machinery Co., Ltd., an excellent manufacturer of ore and industrial grinding equipment, has made significant achievements in ultra-fine powder technology. For a 1-3 TPH petroleum coke grinding project in Indonesia, we highly recommend our LM Vertical Grinding Mill series, specifically the LM130K model from our Vertical Mineral Mill line.
This mill is engineered to excel in precisely such applications. Its integrated design is perfect for medium and small-scale production, offering remarkable energy savings of 30-50% compared to traditional ball mills. The grinding roller and plate are made from wear-resistant materials, significantly reducing the risk of iron contamination—a crucial factor for coating quality. Furthermore, the mill’s intelligent control system ensures stable operation and easy maintenance, which is vital for plants in Indonesia.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM130K | 1300 | 10-28 | 170-40 (80-400 mesh) | <38 | 200 |
As shown in the table, the LM130K offers a capacity range that comfortably encompasses the 1-3 TPH target, with significant headroom for future expansion. Its ability to produce powder from 170 down to 40 microns (approximately 80 to 400 mesh) makes it perfectly suited for coating production requirements.
For projects demanding even finer product or exceptional particle shape, Zenith’s LUM Ultrafine Vertical Mill represents the pinnacle of grinding technology. It is particularly suitable for producing high-value additives where superior fineness and distribution are non-negotiable.
| Model | Main Machine Power (kW) | Capacity (t/h) | Size Distribution D97 (μm) |
|---|---|---|---|
| LUM1125 | ~160 | ~1.5-4 | 5-30 (500-2500 mesh+) |
The LUM series achieves an extraordinary fineness level (D97 from 5 to 30 microns), making it a future-proof choice for premium coating formulations.
Implementing a Zenith LM Vertical Mill for a 1-3 TPH petcoke grinding line in Indonesia brings multifaceted benefits:
