Under the dual drive of the 'dual carbon' goals and the ultra-low emission transformation of the steel industry, metallurgical enterprises need to achieve cost reduction and efficiency improvement through the cleaning and refinement of fuels. As the core fuel for blast furnace injection, sintering, and heat treatment in steel casting, the combustion efficiency and stability of coal powder directly affect the quality of castings and energy consumption levels.
In recent years, there has been a high demand in the industry for high-activity, low-sulfur coal powder. Relying on the technological breakthroughs of the LM series vertical mills, SBM provides high-precision, low-energy coal powder preparation solutions for steel casting enterprises. It has already served multiple steel companies, setting a benchmark for the upgrade of metallurgical fuels.
High-Standard Coal Powder Production Line: Setting a New Benchmark for Energy Efficiency
A company in Shandong plans to build a coal powder preparation project to enhance the quality of casting fuels and reduce reliance on coke. When seeking coal powder preparation solutions, they set extremely high requirements for equipment in terms of energy consumption, production capacity, safety, and environmental performance. After evaluating multiple mill suppliers, SBM LM Vertical Coal Mill, with its outstanding performance in 'ultra-fine grinding, dynamic sulfur control, and intelligent explosion prevention,' became the core equipment for the project, helping the client achieve dual control goals of reducing fuel costs and carbon emissions.
Production Material: Coal Powder
Finished Size: 200 Mesh
Application: Casting Coal Powder
Equipment: LM Vertical Coal Mill
Core Requirements of Project
Particle Size Control: Finished coal powder fineness reaches 200 mesh
Sulfur Content Control: Reduce sulfur release through grinding technology
System Safety: Full-process explosion-proof design, meeting AQ 4272-2016 "
SBM technical team conducted on-site inspections and surveyed data to design a customized solution, employing a "pre-crushing - vertical grinding - classification optimization - inert gas protection" one-step process. The intelligent system detects and adjusts parameters to achieve compliance with both coal powder activity and environmental protection indicators.
Coal Powder Preparation Process Flow
Raw coal is screened and de-ironed before being transported to the raw coal storage，after the system is started, the coal is fed into the vertical coal mill by the feeder, where it is dried and ground with hot air introduced from the hot air furnace. The coal powder is separated by the classifier with the airflow; coarse powder is returned for regrinding, while fine powder is collected into the storage by the explosion-proof dust collector. Impurities are discharged through the air ring, and the system is equipped with CO-O₂ online monitoring throughout the process. During the preparation of high-volatile coal powder, nitrogen protection and CO₂ fire extinguishing systems are linked to ensure safe production.
LM vertical coal mill is specifically developed for coal powder preparation，it integrates crushing, grinding, drying, and classification. It is suitable for various raw materials, including anthracite and bituminous coal，it features adjustable fineness, stable and efficient operation. It also innovatively incorporates a "five-level safety explosion-proof system" to achieve safety control throughout the entire process.
Advantages of LM Vertical Coal Mill
1. Integrated Design for Cost Reduction and Efficiency Improvement: The integrated structure supports outdoor layout, occupying a small area and requiring low investment costs.
2. High-Efficiency Grinding with Quality Assurance: The unique design of the grinding roller and grinding table, combined with a hydraulic automatic pressure device, enhances grinding efficiency, resulting in high single-machine capacity and excellent finished products.
3. Strong Drying Capacity with High Adaptability: The hot air system can handle raw coal with a moisture content of 15%, with stable discharge moisture below 1%, suitable for various working conditions.
4. Intelligent Operation and Maintenance for Cost Optimization: The hydraulic design for roller lifting shortens maintenance time; the thin oil lubrication system extends bearing life and reduces annual maintenance costs.
5. Safety Explosion-Proof System for Comprehensive Protection: The five-level safety protection (online monitoring, nitrogen protection, automatic fire extinguishing, anti-static design, explosion-proof structure) covers the entire process and has received national explosion-proof certification.
