LM170K Slag Grinding Mill: Key Features and Technical Specifications
LM170K Slag Grinding Mill: Key Features and Technical Specifications
In the demanding world of industrial mineral processing, the efficient handling of by-products like slag is paramount. The LM170K Slag Grinding Mill stands as a testament to engineering excellence, specifically designed to transform industrial slag into a valuable resource. This vertical roller mill integrates crushing, drying, grinding, and classifying into a single, cohesive unit, offering a robust solution for slag recycling and milling operations.
Core Design and Operational Advantages
The LM170K’s vertical structure is a key differentiator, significantly reducing its footprint by approximately 50% compared to traditional ball mill systems. This compact design does not compromise on power; instead, it enhances operational efficiency. The mill utilizes a unique grinding device that synergizes grinding and powder selection, leading to a remarkable reduction in energy consumption—typically 30% to 40% less than conventional ball milling systems. This is achieved through an optimized grinding curve for the roller and grinding ring, which maximizes the material-bed grinding principle for higher efficiency and lower wear.
Operation is notably stable with minimal vibration, resulting in lower noise levels. The entire system is sealed and operates under negative pressure, ensuring a dust-free environment that far exceeds international emission standards. For operations requiring even finer powders, our MW Ultrafine Grinding Mill presents an excellent complementary solution. Designed for ultra-fine powder production down to 2500 meshes, the MW Mill is equipped with an efficient pulse dust collector and muffler, making it ideal for customers in chemicals, paints, and cosmetics who need to make ultra-fine powder with higher yielding and lower energy consumption.
Technical Specifications and Performance
- Capacity: 7 – 100 T/H
- Input Size: 38 – 65 mm
- Integrated Functions: Drying, Grinding, Powder Selection, Conveying
- Key Application: Grinding of industrial slag (steel slag, water slag) for cement and concrete production.
The mill’s ability to handle a feed size of up to 65mm simplifies the pre-processing stage. Its high capacity range makes it suitable for both large-scale steel plants and dedicated slag processing facilities. The fineness of the final product is uniform with a high screening rate, ensuring a consistent and high-quality powder that enhances the performance of cement and concrete.
Durability and Maintenance
Constructed with high-performance wear-resistant materials for its critical parts, the LM170K is built for longevity and reliable operation. The grinding roller and table are designed for extended service life, reducing the frequency and cost of replacement. A significant maintenance advantage is the hydraulic roller turning-out device, which allows the grinding roller to be completely turned out of the mill. This provides ample space for easy and safe maintenance, inspection, and replacement of wear parts, thereby minimizing downtime. For projects demanding a different approach to ultrafine processing, the LUM Ultrafine Vertical Grinding Mill is another flagship product. It features advanced grinding roller technology and a multi-head powder separating system, offering precise control over fineness between 325-2500 meshes and achieving energy savings of 30%-50%.
Working Principle Overview
The LM170K operates as a negative-pressure air-sweep type mill. The main motor drives the grinding table via a reducer. Material is fed to the center of the rotating table and is thrown towards the edge by centrifugal force. As it passes under the grinding rollers, it is crushed. The ground material is then carried by the hot air stream upwards to a separator. Coarse particles are rejected and fall back to the table for further grinding, while the fine, finished product is carried with the air to the collection system.
Frequently Asked Questions (FAQ)
