In recent years, the increasing importance of environmental protection and resource efficiency has driven industries across the globe to seek cleaner, more efficient technologies for power generation and water treatment. In Thailand, petroleum coke—a byproduct of oil refining—has emerged as a valuable material for industrial applications, including water treatment and desulfurization. To achieve consistent and fine grinding of petroleum coke for use in these processes, high-performance grinding systems are essential. Among the leading suppliers, Shanghai Zenith Machinery Co., Ltd. has established itself as a top manufacturer of advanced ore and industrial powder grinding equipment. With a focus on precision, sustainability, and cutting-edge technology, Zenith’s mills have been deployed successfully in projects requiring outputs between 20–30 TPH.
Petroleum coke (petcoke) is a carbon-rich solid derived from the thermal cracking of petroleum residues. Although traditionally used as a fuel, its finely ground form has proven effective as an adsorbent and filtration medium in water treatment. Ground petcoke is particularly useful in the removal of impurities, color, and residual organics in wastewater. When appropriately processed, it provides a low-cost and abundant alternative to activated carbon for certain water purification applications.
For successful application, however, the petcoke must be ground to a specific fineness and uniform particle size. This demands advanced grinding equipment capable of handling the material’s hardness and dryness characteristics while maintaining product consistency. In Thailand’s industrial water treatment plants, a grinding mill system capable of producing 20–30 TPH of finely ground petcoke has become a key operational requirement.
Petcoke’s high carbon content and abrasive nature make it a challenging material to grind efficiently. Its low volatile matter also makes dust management essential, as airborne particles may ignite under certain conditions. Consequently, grinding systems must integrate not only mechanical efficiency but also safety features, dust collection systems, and high dynamic classifiers to achieve controlled output fineness.
Another key factor is energy efficiency. Due to progressively stricter environmental regulations, Thai industries are transitioning toward sustainable production models. Selecting an energy-saving grinding system that minimizes emissions and power consumption is critical. This is precisely where Shanghai Zenith Machinery Co., Ltd. comes into play.
Based on the production capacity requirement (20–30 TPH) and material characteristics of petroleum coke, two of Zenith’s products stand out as ideal solutions: the MTW Trapezium Grinding Mill and the LM Vertical Grinding Mill. Each offers distinct advantages for processing petroleum coke in water treatment applications.
The MTW Trapezium Grinding Mill is designed for high-efficiency processing of non-flammable and non-explosive materials with a Mohs hardness less than 9.3 and humidity below 6%. Equipped with advanced European technology, it provides stable performance, precise fineness control, and low noise output. Its unique curved blade design improves material transportation efficiency, while the sealing system ensures a clean working environment, which is crucial for water treatment-related industries.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW138Z | <35 | 1.6–0.045 | 6–17 | 90 | 110 |
| MTW175G | <40 | 1.6–0.045 | 9.5–25 | 160 | 200 |
| MTW215G | <50 | 1.6–0.045 | 15–45 | 280 | 315 |
For Thai water treatment projects requiring a 20–30 TPH production rate, the MTW215G model is an optimal choice. It ensures stable throughput, fine particle control, and low power loss, meeting both quality and environmental standards.
The LM Vertical Grinding Mill represents the next generation in integrated grinding technology, combining crushing, grinding, drying, and powder selection functions into one compact system. Its vertical design minimizes plant footprint, offering a space-efficient and environmentally-friendly configuration that is perfectly suited for large-scale production facilities in Thailand.
This mill’s built-in hot air circulation system allows simultaneous drying of petroleum coke, which has low moisture content but requires stable temperature control during processing. Additionally, its high-efficiency classifier ensures uniform particle distribution—critical for consistency in water treatment media.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM130K | 1300 | 10–28 | 170–40 | <38 | 200 |
| LM190K | 1900 | 23–68 | 170–40 | <45 | 500 |
| LM220X-GX | 2200 | 15–30 | 325–600 mesh | – | 560 |
From this range, the LM220X-GX model is particularly well-suited for 20–30 TPH grinding operations. Its ability to produce ultrafine petcoke powder at 325–600 mesh levels ensures optimal chemical reactivity and filtration quality in water treatment applications.
In a recent project located in eastern Thailand, a private industrial water treatment plant adopted Zenith’s LM220X-GX vertical mill for processing petroleum coke feedstock. The primary requirement was to achieve 25 TPH of ultra-fine petcoke powder used as filtration media for industrial effluent polishing. The system achieved over 98% operational uptime, producing a consistent product with a D97 fineness of 400 mesh. The vertical design also allowed the operator to reduce the plant’s footprint by 25% compared to a traditional ball mill setup.
The integration of hot gas streams from existing plant boilers allowed the drying process to occur simultaneously, eliminating the need for a separate drying system. This created additional operational savings while reducing CO2 emissions.
Thailand’s water treatment sector continues to expand and innovate, integrating sustainable technologies to meet both production and environmental goals. Petroleum coke, once considered merely a fuel byproduct, is now being successfully repurposed as an eco-efficient filtration material—thanks in part to advanced grinding technologies. With its globally recognized expertise and comprehensive product line, Shanghai Zenith Machinery Co., Ltd. stands ready to support Thai industries in achieving cleaner, more efficient operations.
For facilities targeting a 20–30 TPH output, Zenith’s MTW215G Trapezium Grinding Mill and LM220X-GX Vertical Grinding Mill deliver unmatched performance, efficiency, and reliability, making them the best equipment choices for petroleum coke preparation in water treatment applications.
