What are the features of vertical mill?2015-04-28
Vertical mill are suitable for huge capacity and fineness between 30 to 1000 mesh powder producing, widely used in grinding non-flammable and non-explosive materials under 9.3(the Moh's hardness), such as quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, especially for slag, cement clinker, zircon sand, fly ash and carborundum, coal, etc.
Series vertical mill is integrated with crushing, drying, grinding and separating. Process flow is easy. Compared with tube mill, vertical mill has many advantages. High grinding efficiency; Reducing 20-30% electricity consumption; Big drying ability; Material moisture can be 15%; Material in-size is bigger; Degree of product fineness is easier to adjust; Chemical composition is steady; No steel ball impact; No direct touch between metals; Low noise; Low wear; There is separator in mill, no need to match powder concentrator; Small cover area; Grinding rollers of vertical mill can be taken out of the mill; Easy maintain and so on.
Advantages of vertical mill:
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.
