| Not long ago, Shanghai zenith company expert on | | | | The fine powder comes out with the airstream, |
| the basis of former grinding mill design anew | | | | and is gathered by the dust catcher of the |
| type of grinding mill-vertival roller mill. | | | | system. The powder gathered is the final product |
| Vertical roller mill is on purpose to grind mining | | | | of roller mill. |
| materials in the fields of metallurgy, building | | | | 4) In the process of the contact of airstream , |
| materials, chemistry, mining and so on. It can grind | | | | the materials are dried to meet the clients' need |
| the non-flammable and non-explosive mineral | | | | at the proper moisture. Through the |
| materials with the Moh's hardness lower that scale | | | | adjustment of the angle between the separator |
| 9.5 such as quartz, feldspar, calcite, talcum, barite, | | | | and the leaf of wind's direction (not suitable to the |
| fluorite, rare earths, marble, ceram and so on. | | | | small type of vertical mill), and also the speed of |
| Vertical Roller Mill Working Principle: | | | | the separator rotor, it can reach the proper |
| 1)The motor dives the grinding table to turn | | | | fineness of the materials. |
| through the speed reducer. At the same time, | | | | Compared with other grinding mills, vertival roller |
| hot air comes into the roller mill from the air inlet. | | | | mill has many advantages: |
| The materials fall down the centre of grinding | | | | (1)The time materials stayin the machine body is |
| table from the feeder. | | | | short ,which can reduce the repeating grinding and |
| 2)Because of the centrifugal force, the materials | | | | have a stable quality. |
| move to the edge of grinding table from the | | | | (2)The adjustable dry air temoeture,and high |
| centre | | | | drying ability ,energy-saving |
| 3).The materials are crushed by the grinding roller | | | | (3)The non-direct contacting equipment installed on |
| when they passes the groove on the grinding | | | | the roller shells and the grinding liner can avoid the |
| table. The crusher materials continue to move to | | | | damage compact and strong shaking. |
| the edge of the grinding table until they are taken | | | | (4)The grinding roller and the liner adopts the |
| away by the airstream. Then the bigger materials | | | | high-quality materials ,which can reduce the |
| fall down the grinding table and the process of | | | | abrasion and increase the service life . |
| crushing continues. When the materials in the | | | | (5)The whole seal of the equipment makes the |
| airstream pass the separator on the top of the | | | | system work in a negative environment with no |
| mill, the materials fall down the grinding table from | | | | dust leaking and a clean environment. |
| the taper filler under the force of guide leaf blade. | | | | |
