Afghanistan’s industrial sector is gradually expanding, with significant emphasis on sustainable raw material processing and local production development. Among the diverse industrial materials, petroleum coke (petcoke) has gained attention as a key energy and filler source. Its usage in the paper-making industry, as a fuel and additive, provides both cost efficiency and environmental benefits. However, to fully utilize the potential of petcoke, it must be processed into ultrafine powder using an efficient grinding mill system. A production capacity of 20-30 TPH (tons per hour) is an optimal scale for medium paper plants in Afghanistan, balancing output efficiency and operational cost.
Shanghai Zenith Machinery Co., Ltd., an industry-leading manufacturer from China, has achieved outstanding innovation in ultra-fine powder grinding. With a range of advanced grinding equipment such as the MTW Trapezium Grinding Mill, LM Vertical Grinding Mill, and LUM Ultrafine Vertical Mill, Zenith provides professional and environmentally friendly solutions for various industries.
Petroleum coke, a carbon-rich material from oil refining, is characterized by its high calorific value, low ash content, and consistent chemical composition. When processed into fine powder (typically under 45 microns), petcoke can serve as an energy-saving and emission-reducing substitute for coal in lime kilns used in the paper industry. Additionally, finely ground petcoke can function as a carbon additive in paper filler processing, enhancing paper whiteness and strength when combined with calcium carbonate.
Afghanistan presents unique challenges for industrial operations due to infrastructure constraints, energy supply instability, and geographical conditions. Efficient grinding facilities must therefore meet the following criteria:
Considering these factors, Shanghai Zenith Machinery recommends two specific milling solutions suitable for achieving a 20-30 TPH output in Afghanistan: the MTW Trapezium Grinding Mill and the LM Vertical Grinding Mill.
The MTW series represents an advanced generation of grinding mills developed based on European technology. It is equipped with a bevel gear drive, internal thin oil lubrication system, and arc air channel design, ensuring energy efficiency and environmental safety. This mill is particularly suitable for grinding petcoke to the fineness required for industrial paper production applications.
For a target production of 20-30 TPH, the MTW175G or MTW215G models are recommended based on their capacity range, robust mechanics, and adaptability to medium-scale installations.
| Model | Max. Feed Size (mm) | Final Size (mm) | Capacity (t/h) | Main Motor (kW) | Fan Motor (kW) |
|---|---|---|---|---|---|
| MTW175G | <40 | 1.6-0.045 | 9.5-25 | 160 | 200 |
| MTW215G | <50 | 1.6-0.045 | 15-45 | 280 | 315 |
The MTW Trapezium Grinding Mill employs high-efficiency classifiers that allow precise control of product fineness. Its design prevents material backflow and ensures consistent particle size distribution, key to achieving uniform burning properties when petcoke is used in rotary kilns. Moreover, the modular design of key components enables simplified replacement and maintenance, making it ideal for the working environment in Afghanistan.
The LM Vertical Grinding Mill integrates crushing, grinding, drying, and conveying in a single structure, minimizing floor space and eliminating the need for external drying equipment. Its versatility makes it suitable not only for petcoke but also for limestone, coal, and slag processing in paper production facilities.
For Afghanistan’s 20-30 TPH project requirement, the LM190K model is perfectly aligned in terms of capacity, energy utilization, and overall system efficiency.
| Model | Plate Diameter (mm) | Capacity (t/h) | Output Fineness (μm) | Max Feed Size (mm) | Main Motor (kW) |
|---|---|---|---|---|---|
| LM190K | 1900 | 23-68 | 170-40 | <45 | 500 |
The LM vertical mill’s drying capability allows processing of petcoke with up to 10% moisture, eliminating the need for pre-drying stages. This is crucial for Afghanistan, where environmental conditions can lead to moisture variations in the raw material. Additionally, its intelligent control system ensures optimized energy allocation, prolongs service life of grinding rollers, and guarantees low operational costs.
While both the MTW and LM series deliver exceptional performance, their selection depends on specific customer considerations:
Both systems guarantee compliance with environmental protection standards through dust collector integration and smooth airflow design that reduces emissions.
Zenith’s design philosophy revolves around efficiency and reliability. A typical petcoke grinding circuit for paper production in Afghanistan includes:
Such a configuration guarantees high efficiency, low power consumption, and continuous, automated operation, which are essential to compete in industrial-scale paper manufacturing.
Transitioning to petroleum coke powder in Afghanistan’s paper sector provides multiple advantages:
Overall, Shanghai Zenith’s grinding technology delivers a comprehensive, turn-key approach for building sustainable and economical grinding systems adapted for emerging industrial regions like Afghanistan.
For Afghanistan’s 20-30 TPH petroleum coke grinding project associated with paper making, the selection of appropriate technology is crucial.
