The LM Vertical Roller Mill is an energy-efficient grinding equipment developed by Liming Heavy Industry. With its advanced structural design and mature grinding technology, it is suitable for large-scale grinding of non-metallic minerals, industrial solid waste, building materials, etc. The vertical mill features stable operation, low energy consumption, and simplified maintenance, meeting the needs of powder production with different finenesses.

Advantage

1. High Energy Efficiency
Advanced roller pressure technology, high grinding efficiency, energy consumption reduced by 30% to 50% compared to traditional ball mills.
2. Adjustable Product Fineness
The final product fineness (80-600 mesh) can be adjusted by changing the classifier speed or airflow.
3. Stable Operation
Hydraulic system automatically adjusts roller pressure, reducing vibration for long-term stable operation.
4. Eco-friendly and Quiet
Fully enclosed vacuum operation, dust emissions meet standards, low noise, and are environmentally friendly.
5. Easy Maintenance
Roll-out rollers for maintenance, and main parts made of wear-resistant materials ensure a long service life and reduced maintenance costs.

Working Principle

During operation of the LM Vertical Roller Mill, materials enter the center of the grinding table via the feed system and move towards the edge under the effect of centrifugal force. The rollers apply grinding pressure through the hydraulic system, while hot air enters through the nozzle to dry the materials and transport them upwards. Fine particles are selected by the classifier to form the final product, while coarse particles fall back onto the table for a new grinding cycle.
