Why is the crossbeam of sand vibrating screen fragile?
The crossbeam of sand vibrating screen lies in the upside of vibrating sieve frame to support vibrator, which is the main crossbeam of vibrating screen. Box-type vibrator is very popular in manufacturing vibrating screen field recent years. Generally there is a firm crossbeam on sand vibrating screen adopting to box-type vibrator. This vibrating screen is widely used in coal preparation plant at present. Some users often asked us about “why is the crossbeam of sand vibrating screen always fragile?”.LZZG can give you easy and general answers about this question.
Firstly we need to understand the crossbeam is a structural part in sand vibrating screen that bears complex forces. The main effect is to support vibrator and offer sand vibrating screen exciting force. Therefore, when designing the crossbeam of vibrating screen, designers not only need to think about force strength but also reason force in structure. Now many vibrating screen manufacturers designed the crossbeam of vibrating screen only by measuring and copying in present market, so these machines is easy to break down. If the design of vibrating screen is not professional, it’s useless to produce vibrating screen by using the best raw materials.
Secondly manufacturers should produce sand vibrating screens according to the design drawing and should focus on the following points.
It is necessary to use the specified welding rod for welding.
According to the requirements of the design drawing, weld the prototype frame of vibrating screen accurately and inerrably.
The geometrical frame of vibrating screen should be guaranteed by reasonable process.
Having heat treatment according to the requirements of the vibrating screen design drawing.
In addition, users should pay more attention on the reasonable maintenance for the crossbeam of vibrating screen in using. The upside of the crossbeam of sand vibrating screen installs the vibrators that are connected by bolts. If these bolts are loose, the crossbeam of sand vibrating screen will be influenced doubt. The maintenance crossbeam of vibrating screen is to check the tightness of bolts between crossbeam and vibrator. In general, to check the bolts of sand vibrating screen every week.
