Analysis of the working principle of the vertical mill

The working principle of the vertical mill is based on the compression and shearing forces between two grinding rollers, which are driven by a motor to rotate at a high speed. The material to be ground is fed into the center of the grinding table, where it is crushed and ground by the grinding rollers.

Here is a step-by-step analysis of the working principle of the vertical mill:

1. Material feeding: The raw material is fed into the center of the grinding table through a chute or elevator.

2. Grinding table rotation: The grinding table rotates at a constant speed, driven by a motor, and the material is spread out evenly across the table surface.

3. Grinding roller operation: Two grinding rollers, located above the grinding table, rotate in the opposite direction at a high speed. The material is crushed and ground by the compression and shearing forces between the grinding rollers and the grinding table.

4. Material separation: The ground material is carried by the air flow generated by the grinding rollers and is transported to the classifier located at the top of the vertical mill. The fine material is separated from the coarse material and is collected in the cyclone separator.

5. Final product collection: The final product is collected in the bag filter or other dust collection device.

Here is a table summarizing the working principle of the vertical mill:

| Step | Description |

|------|-------------|

| Material feeding | The raw material is fed into the center of the grinding table through a chute or elevator. |

| Grinding table rotation | The grinding table rotates at a constant speed, driven by a motor, and the material is spread out evenly across the table surface. |

| Grinding roller operation | Two grinding rollers, located above the grinding table, rotate in the opposite direction at a high speed. The material is crushed and ground by the compression and shearing forces between the grinding rollers and the grinding table. |

| Material separation | The ground material is carried by the air flow generated by the grinding rollers and is transported to the classifier located at the top of the vertical mill. The fine material is separated from the coarse material and is collected in the cyclone separator. |

| Final product collection | The final product is collected in the bag filter or other dust collection device. |

Please note that this working principle is only for reference and may vary depending on the specific model and manufacturer of the vertical mill. It is recommended to consult with a qualified technician or manufacturer for a proper diagnosis and repair.
