In Vietnam, traditional coal powder preparation processes have long been plagued by three major pain points: unstable fineness of coal powder, excessive dust pollution and high energy consumption. They fail to comply with increasingly stringent local environmental regulations and meet the demands for high efficiency and stable operation in modern production, acting as a major bottleneck restricting Vietnam’s clean energy transition. Against this backdrop, with nearly 40 years of in-depth expertise in grinding equipment and rich global project experience, Shanghai Zenith has accurately identified industry challenges and tailored exclusive coal powder preparation solutions for Vietnamese clients, boosting the high-quality development of the local clean energy industry.

In this project, the client required coal to be ground to 200 mesh for efficient combustion. This high standard set strict requirements for equipment grinding accuracy, system stability and environmental compliance. Drawing on profound technological accumulation in the grinding industry, numerous successful global references and continuous R&D innovation capabilities, Shanghai Zenith has gained full recognition from the client, serving as the exclusive supplier of core equipment and integrated solutions to ensure the smooth implementation of the project.

The core parameters of this project are clearly defined to precisely meet the client’s production requirements. The processed material is coal, with the finished particle size strictly controlled at 200 mesh. The key equipment adopted is the Zenith LM Vertical Coal Mill, independently developed by Shanghai Zenith specially for coal powder production. As the core support of the overall solution, it balances high efficiency, environmental protection and safe operation.

To ensure the adaptability and feasibility of the solution, Shanghai Zenith conducted in-depth research on local coal characteristics, environmental policies and production pain points in Vietnam at the early stage. By overcoming the drawbacks of traditional processes, we provide a customized full-process solution centered on the LM Vertical Coal Mill. It realizes both high production efficiency and eco-friendly operation, fully aligning with Vietnam’s development trend of clean energy transition.

As the core equipment of the complete solution, LM Vertical Coal Mill addresses major industry bottlenecks thanks to its distinctive design advantages. Integrating crushing, grinding, drying and powder separation in one unit, it is highly adaptable to diverse coal materials including anthracite and bituminous coal. It stably delivers qualified 200 mesh coal powder with precise fineness control, while maintaining high operation efficiency and low energy consumption. Equipped with an innovative five-level safety and explosion-proof system, together with online monitoring and automatic fire suppression devices, the mill enables full-process safety management, eliminates dust pollution and potential hazards at the source, and thoroughly solves the inherent defects of traditional processes.

Beyond the superior performance of the core equipment, the solution features four prominent advantages to comprehensively improve customers’ return on investment and production convenience:

Outstanding Cost-effectiveness

Adopting a one-step technological process, it requires no additional drying or classifying equipment. The integrated grinding and drying design greatly simplifies procedures and effectively reduces overall project investment.

Powerful Drying Capacity

With hot air conveying, it efficiently processes raw coal with incoming moisture up to 15%, controlling final moisture content below 1% and ensuring stable coal powder quality.

Superior Explosion-proof Performance

The five-level explosion-proof system is equipped with CO-O₂ online gas analysis and automatic CO₂ dilution & fire-extinguishing system, providing comprehensive risk prevention during coal powder preparation.

High Level of Automation

The intelligent control system supports remote operation, interlock protection, real-time monitoring and early warning, greatly simplifying daily operation and cutting labor costs.

Shanghai Zenith always adheres to the philosophy of full process service and full lifecycle support, covering every stage of the project. This cooperation fully demonstrates Shanghai Zenith’s strong technical strength and comprehensive service capabilities in grinding equipment, and also serves as a vivid practice of boosting the global clean energy transition. Moving forward, with a global vision and localized services, Shanghai Zenith will continue to focus on industry pain points and strengthen R&D innovation. We will provide customized, high-efficiency and eco-friendly grinding solutions for more global clients, and advance the high-quality development of the clean energy industry worldwide.
