How to solve the problem of vibrating screen bearing heating

          Circular vibrating screen working principle is to use a vibrating screening equipment , screening material because of its large capacity, high efficiency, simple

structure , stable and reliable , and Vibrating feeder therefore the wider application of sand making production line . In addition to the main components shaker vibration under

Beyond the number necessary to move the motor to the bearing , the bearing will have a direct impact on the quality of vibrating screen , vibrating screen bearings in use , the

temperature rise is too large, easy to make the vibrating screen bearings produce damage , affecting the use of vibrating screen . Excessive heat vibrating screen bearings are

mainly the following reasons:
1 , lubrication unreasonable , Pan feeder , or too much or too little fuel .
2 , vibrating screen bearing structure design is unreasonable .
3 , the bearing manufacturer is qualified.
4, the lubrication system is a problem .
5 , if it is a new screen, it must be process issues, circular vibrating screen sieve if it is old , stiffness , infrastructure and so on.
6 , the bearing with the bearing with a reasonable selection, fever and affect the bearing life.
7 , cement vibrating screen bearings precision problem, because domestic processing precision is not enough , so the use of three groups of large clearance bearings, these

bearings are used at the expense of increasing the noise .
8 , the focus error is too large sieve .
9 , vibrating screen bearing clearance to choose appropriate.
10 , bearing installation is correct or not , tolerances reasonable or not, electromagnetic shaker is critical fever .
Circular vibrating screen work process is to rely on power running , never load low speed and slowly increase to the conditions set rated operation . So clients commissioning

circular vibrating screen items must be checked as whether group in abnormal noise , bearing temperature shift , catch and release lubricant such as discoloration

And so on. Check the bearing temperature shaker general appearance from the housing speculation seen. But the use of the hole , the direct measurement of the bearing outer ring

temperature , more accurate. Start of operation of the bearing temperature rises gradually , without exception , typically 1 to 2 hours after stabilization . If the installation

due to bad bearings or bearing temperature

Will soar . The case of high-speed rotation , the bearing lubrication method of choice is the cause of the error .
