Asphalt is a high-quality pavement material widely used in highway and municipal road construction. In the asphalt production process, heating is a key procedure to guarantee asphalt quality and ensure subsequent mixing performance.
At present, pulverized coal has become the core fuel for modern asphalt mixture production. With the gradual depletion of coal resources in China, coal processing and utilization are transforming toward refinement and high efficiency.
Against this backdrop, clean coal powder preparation projects strictly comply with national policies on green development and energy conservation. They effectively extend the value of the coal industrial chain, promote the efficient utilization of clean energy, and strongly support the long-term, eco-friendly and sustainable development of asphalt production and related industries.
As a global manufacturer of grinding equipment, SBM has always adhered to technology-driven development. Through continuous R&D investment and technological iteration, it provides comprehensive solutions for clean coal powder preparation.
The company boasts a professional R&D team of nearly 100 people and has established a sound R&D and innovation system. With years of technical accumulation and market verification, it has developed two mature process route solutions tailored to different raw material characteristics and product requirements. Both adopt industry-leading technical equipment to ensure the reliability and economy of system operation.
Application of LM Vertical Mill Technology in One-Step Process
For application scenarios where the raw material moisture content is ≤15%, SBM has launched a one-step process solution based on the LM Vertical Coal Mill. This process innovatively integrates drying, grinding and classification functions into one, significantly simplifying the process flow and reducing investment costs and operational energy consumption.
Technical Advantages of Complete LM Vertical Coal Mill System
1. Leading Technology & High Integration
Adopting an integrated design with a streamlined and efficient process flow, the LM vertical mill combines crushing, drying, grinding, powder selection and conveying into a single unit, eliminating the need for multiple separate devices. It features a compact and reasonable layout, supports outdoor installation, and greatly saves floor space and preliminary planning costs.
2. Convenient Operation & Maintenance, Controllable Operating Cost
The equipment is simple and easy to operate. It is equipped with an automatic forced thin oil lubrication system to provide automatic lubrication and protection for key components such as grinding rollers. Fitted with a hydraulic roller tilting device, the grinding roller can be flipped out of the mill via the hydraulic system during maintenance, which greatly expands the maintenance space, reduces maintenance difficulty and workload, and effectively lowers long-term operating costs.
3. High Automation & Stable Operation
The complete system is equipped with a full automatic control system, enabling remote operation and one-click start-stop. It also has complete interlock protection functions, which reduces labor intensity, ensures stable and safe equipment operation, and delivers easy operation with low failure risk.
4. High Efficiency & Environmental Compliance
The entire pulverizing production line operates in a negative-pressure sealed mode and is equipped with an explosion-proof plenum pulse dust collector, achieving zero dust emission. It features low noise and low energy consumption, with all environmental indicators meeting the latest national environmental protection standards, helping enterprises realize green production.
5. High Productivity & Outstanding Drying Capacity
Compared with traditional grinding equipment, the LM vertical mill delivers higher grinding efficiency, larger output and lower energy consumption. Hot air can be directly introduced into the mill interior to efficiently dry raw coal with incoming moisture up to 15%, keeping the finished coal powder moisture below 1% and fully meeting the fuel quality requirements of asphalt mixing plants.
6. Comprehensive Safety Protection & Standard Compliance
The system is fully equipped with five-stage safety and explosion-proof measures to eliminate potential safety hazards in the pulverizing process from the source. Its design strictly complies with relevant national and industrial specifications, ensuring safe and reliable operation and providing solid support for enterprise safe production.
After years of in-depth cultivation, SBM has always been committed to researching clean coal powder preparation technology, continuously iterating products, providing customized process solutions for different application scenarios, and helping numerous enterprises achieve success.
