vertical raw mill
The vertical mill of raw material is used for grinding cement raw material or cement clinker and other industrial materials such as construction, chemical and ceramic. It has a series of advantages, such as small volume, light weight, less land occupation, low electricity consumption, long life and so on. Therefore, it has been widely used in industrial developed countries in recent years.
Advantages
1. High grinding efficiency: save 20~30% power consumption compared with the ball mill. With the increasing of moisture content, it can save more and more electricity.
2. Strong drying capacity: dry and grind raw materials with moisture content as much as 15%.
3. Mutifunction: crushing, drying, grinding, separating and conveying.
4. Low noises and little dust: no direct contact between the grinding rollers and grinding disc, so metallic impact is avoided and its noises is 20~25 decibels lower. Totally closed negative pressure operation has employed by this vertical grinding mill, so there is no dust during the operation.
5. Low wear rate and little metallic pollution: its metal wear is only 5~10g/t
