Is it better to grind cement raw materials using a ball mill or a vertical mill?
Thread Content
It is well known that vertical mills are more energy-efficient than ball mills, but their investment cost is much higher. Vertical mills have many advantages over ball mills; why then, after so many years since their introduction, have they not completely replaced ball mills? Please share your insights on aspects such as energy conservation, safety, environmental protection, investment, management and maintenance costs, and operation.
Currently, vertical mills are the mainstream, with only a few using ball mills.
Vertical mills have significant advantages in terms of energy savings and environmental protection; they consume less energy and generate less noise, and their operating costs are also low. However, they require high levels of maintenance. Although the lining plates have a long service life, the grinding heads wear out rapidly, resulting in a short replacement cycle that affects operational efficiency.
