Introduction to the advantages of environmental protection, energy saving and low cost of vertical mill
1. Environmental Protection and Energy Saving: The vertical mill operates with low vibration, minimal noise, and reduced dust emissions, creating a cleaner and more environmentally friendly working environment that meets modern sustainability standards.
2. Low Construction Cost:
(1) The vertical mill has a simplified process, reducing the floor space by approximately 50% compared to a ball mill system. This significantly cuts down on construction costs by about 70%, as it requires less space and fewer structural supports.
(2) The vertical mill integrates crushing, drying, grinding, classification, and conveying into one compact system. This makes it easy to install in open areas, further lowering construction expenses and improving overall efficiency.
3. Strong Drying Capacity: The vertical mill uses gas to transport materials during the grinding process. When processing materials with high moisture content, the inlet air temperature can be precisely controlled, allowing the final product to reach a moisture level of up to 12–15%. In contrast, traditional systems can only dry materials to around 3–4% moisture.
4. Low Operating Costs:
(1) High milling efficiency is achieved through the use of grinding rollers and a material bed, resulting in lower energy consumption. The power consumption of the vertical mill system is reduced by 40–50% compared to ball mills, especially when dealing with wet raw materials.
(2) The lining plates and grinding rollers are made from specialized materials, ensuring long service life and reducing maintenance and replacement costs.
(3) An external circulation device is included, further enhancing energy efficiency and reducing power usage.
(4) The mill can handle large feed sizes—up to 5% of the roller diameter, typically ranging from 40–100 mm—which eliminates the need for secondary crushing in many cases.
5. Stable Product Quality: The short residence time of materials inside the mill allows for easier control over particle size and chemical composition, ensuring consistent and high-quality output.
6. Easy Maintenance: Key components such as the oil cylinder, rotating arm, roller sleeve, and liner can be quickly replaced or repaired, minimizing downtime and maintenance efforts.
7. Easy to Operate:
(1) The system is equipped with an automatic control unit, enabling remote operation and simplifying daily management.
(2) A safety device prevents direct contact between the roller sleeve and the disc liner, reducing wear and avoiding excessive vibration during operation.
