The working principle of the three-ring medium-speed mill

The three-ring medium-speed mill is a type of grinding equipment that can grind various non-metallic minerals into fine powder. Here is the working principle of the three-ring medium-speed mill:

1. The main unit drives the central shaft to rotate through a reducer, and the upper part of the shaft is connected to the plum blossom frame.

2. The plum blossom frame is equipped with several grinding rollers, which rotate around the central axis of the shaft. The grinding rollers are tightly pressed against the grinding ring by the centrifugal force generated by the rotation of the shaft.

3. The material is fed into the grinding chamber through the feeding device, and is ground by the grinding rollers and the grinding ring. The ground material is blown by the air flow generated by the blower, and is classified by the classifier.

4. The qualified fine powder is collected by the dust collector, and the coarse particles are returned to the grinding chamber for re-grinding.

Here is a table summarizing the working principle of the three-ring medium-speed mill:

| Step | Description |

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

| Step 1 | The main unit drives the central shaft to rotate through a reducer, and the upper part of the shaft is connected to the plum blossom frame. |

| Step 2 | The plum blossom frame is equipped with several grinding rollers, which rotate around the central axis of the shaft. The grinding rollers are tightly pressed against the grinding ring by the centrifugal force generated by the rotation of the shaft. |

| Step 3 | The material is fed into the grinding chamber through the feeding device, and is ground by the grinding rollers and the grinding ring. The ground material is blown by the air flow generated by the blower, and is classified by the classifier. |

| Step 4 | The qualified fine powder is collected by the dust collector, and the coarse particles are returned to the grinding chamber for re-grinding. |
