How to solve the common faults of multi-functional crusher

How to solve the common faults of the multi-functional pulverizer 1.
The multi-functional pulverizer adopts the motor to directly connect the pulverizing device.
If it is not well connected during the assembly process, it will cause the overall vibration of the multi-functional pulverizer
.

1.
The rotor of the motor and the rotor of the multi-functional pulverizer are not concentric
.

You can move the position of the motor left and right, or add pads under the motor feet to adjust the concentricity of the two rotors
.

2.
The rotor of the multi-functional pulverizer is not concentric
.

The reason is that the two bearing surfaces supporting the rotor shaft are not in the same plane
.

A copper sheet can be placed on the bottom surface of the support bearing seat to ensure that the two shaft heads are concentric
.

　　3.
Part of the crushing chamber vibrates greatly
.

The reason is that the connection between the coupling and the rotor is not concentric or the quality of the crushing hammer is not uniform
.

Corresponding methods can be taken to integrate the connection between the coupling and the motor: when the quality of the hammers is uneven, each group of hammers must be re-selected, so that the error of the symmetrical hammers is less than 5 grams
.

　　4.
The original balance is destroyed, or the dynamic balance test is performed after the motor is repaired to ensure the overall balance
.

　　5.
The anchor bolts of the multi-functional pulverizer are loose or the foundation is not strong.
During installation or maintenance, the anchor bolts should be tightened evenly, and a shock absorbing device should be installed between the anchor foundation and the pulverizer to reduce vibration
.

　　6.
The hammer is broken or there are hard debris in the crushing room
.

These will cause the unbalance of rotor rotation and cause the whole machine to vibrate
.

Therefore, it is necessary to regularly check the severely worn hammer
.

When replacing, replace it symmetrically
.

　　7.
The connection between the pulverizer and other auxiliary equipment does not match
.

For example, improper connection of feeder, feed pipe, and discharge pipe will cause vibration and noise
.


2.
Bearing overheating Bearing is an important part of the pulverizer, and its performance directly affects the normal operation and production efficiency of the equipment
.

During the operation of the equipment, the user should pay special attention to the heating of the bearing and the noise of the bearing part, and the abnormality should be dealt with as soon as possible
.

　　1.
The bearing seat is uneven, or the rotor of the motor and the rotor of the pulverizer are not concentric, which will cause the bearing to be impacted by additional load, which will cause the bearing to overheat
.

In this case, stop the machine immediately to eliminate the fault to avoid early damage to the bearing
.

　　2.
Too much, too little or aging lubricating oil in the bearing is also the main reason for the bearing to be damaged due to overheating.
Therefore, it is necessary to add lubricating oil on time and quantitatively as required.
Generally, the lubricating oil occupies 70-80 of the bearing space.
Less is conducive to bearing lubrication and heat transfer
.

Bearings extend their service life
.

　　3.
The fit between the bearing cap and the shaft is too tight, and the fit between the bearing and the shaft is too tight or too loose, which will cause the bearing to overheat
.

Once this problem occurs, friction noise and obvious swinging will occur during the operation of the equipment
.

Shut down and remove the bearing
.

Trim friction areas and reassemble as required
.
