In production, Raymond Mill will inevitably encounter a variety of problems, some time ago, users have asked Xiaobian to consult the Raymond mill host has been vibrating how to do. This is one of the common faults of Raymond Mill, and it is also a problem that many users are troubled with. Today, Xiaobian will give you 15 reasons for vibration. There is always one that can solve your "immediately urgent"!

1. The grinding machine anchor bolts are loose

This phenomenon is more common, mainly because the vibration during the grinding process of the machine causes the bolt to loosen, which in turn leads to an increase in vibration. The machine should be inspected in time and the bolts tightened.

2, the foundation is not strong

The working principle of Raymond Mill is circular motion. Vibration will occur during normal working. If the installer does not tighten when hitting the foundation, the Raymond mill will vibrate greatly and the noise will be large. The solution is to reinforce the foundation.

3, the installation problem

When the Raymond mill is installed, the center line of the main drive section is not straight, and vibration occurs during the rotation. In this case, the center line should be adjusted in time.

4, the feed size is too fine or too large

If the feed particle size is too fine, the grinding roller and the grinding ring are easily in direct contact, causing noise and vibration, and the amount of return of the mill should be appropriately reduced. If the feed particle size is too large, the amount of return should be increased to fill the gap between the large particles to achieve crushing of the layer.

5, uneven feeding or less feeding

If the feeding time is too small, or the feeding is very small, the feeding amount of the grinding machine is not enough, causing the Raymond grinding to dry, that is, the grinding roller directly contacts the grinding ring, causing noise and vibration. The feed amount can be controlled by adjusting the vibrating feeder to avoid empty load operation as much as possible.

6, the material pressure is not enough, the feed has no continuity

The mill not only has certain requirements on the particle size of the feed, but also requires continuous feeding and maintains a certain material pressure. To ensure this, a steady flow device can be added to the mill.

7, the material is too strong

The mill, especially the ultra-fine mill, has a strict limit on the hardness of the material. Exceeding its working range will result in a decrease in output, a severe vibration of the main engine, and an excessively coarse stone powder. Therefore, the hardness of the material must be controlled.

8, the material in the volute is blocked

Some materials are too wet and tend to stick together at the damper, resulting in poor airflow and vibration. Always remove the blocking material inside.

9, grinding roller deformation

Long-term wear causes the shape of the grinding roller to change, the grinding roller is not round, and the grinding ring collides with the grinding ring to cause severe vibration. The grinding roller should be replaced in time.

10, analysis machine blade imbalance

Check whether the blades of the analyzer are complete. Some manufacturers save the cost in order to save trouble, and install the blades without debugging, which leads to vibration caused by unqualified production in the later stage.

11, the internal parts of the equipment are loose

The largest part of the Raymond mill is the plum blossom frame and the grinding roller. Both parts are bolted. When the equipment is running, it will generate a strong airflow inside. If these two parts are loose, the airflow will become very unstable, and vibration will occur slowly, causing noise.

12, Raymond mill host grinding chamber mixed metal objects

Due to the high speed of the central axis of the main engine, the metal objects are very hard. After being scooped up by the blade, they will collide in the grinding chamber of the main machine to cause the main machine to vibrate, and the metal objects need to be cleaned.

It should be noted that the metal objects may be brought in from the raw materials, or the parts inside the Raymond mill may fall off, such as screws or bearing balls.

13, the main engine and reducer coupling different shaft

The direct power of the main engine and the reducer is transmitted through the coupling. After the start-up is rotated, the main engine and the reducer will generate vibration and noise due to the different axes of the two couplings. Therefore, the coupling should be calibrated before starting. Coaxiality.

14. There is no gap between the main engine and the reducer coupling

During installation, there is no gap between the main engine and the reducer coupling. Pushing the thrust bearing up will also cause the vibration of the Raymond mill. The solution is to reset the center shaft and re-adjust the coupling clearance.

15, quality issues

If the Raymond mill bearing is of poor quality and the gap is large, it will cause the plum blossom frame to oscillate, which will cause vibration of the equipment.

PC Board Hot Processing

PC board hot forming is to put the board into the machine with higher temperature for a period of time to soften it, and then put it into the mold prepared in advance to cool and form. It can be used for various PC products.
