How to maintain vibrating screen reasonably
The vibrating screen is mining machinery equipment with a double-degree-freedom directional forced vibration property, which is widely used in the cement industry. It has lots of advantages, such as simple structure, stable work, high efficiency and low consumption. However, in the practical application, the phenomenon of unreasonable maintenance and unstable work is universal. And after a period of using, the transmission capacity for material decreases obviously. At this situation, if the maintenance is unreasonable, the normal operation of the machine will be affected seriously.
When the vibrating screen is working, under the effect of vibrator, the screen box and screen cloth will move on a circular, oval, or linear motion, which will make the material on the surface of screen disperse and move up and down. Thus, the fine particles can fall through the material layer and then expel from the sieve hole. And the bigger particles will continue to move forward under the effect of vibration. Through the careful observation to the operation process of vibrating screen, the researchers conclude the general steps for the daily maintenance of vibrating screen ---- Learn the operation state of the equipment through observing and listening. That is to say, through observing the indicator on the amplitude sign, and combining the current of the equipment operation, give a synthetic judgment for the working state of the vibrating screen. And the listening means listening to the operation voice of the working equipment to know whether exist the situation of equipment components loosing. Discover in time and dispose in time. Another thing to notice is that the internal dust of the vibrating screen should be cleaned regularly.
The loss of vibrating screen mainly reflects in the wear or fracture of the vibrating plate and the fracture of the tub bolt. Once this situation appears, the components must be changed timely. If the current value is high in the normal operation, the air gap must be adjusted to the standard value in time. What’s more, the functional components are the foundation of the whole vibrating screen. Only when those functional components develop towards the direction of high speed, high accuracy, high power and high intelligence, can the level of vibrating screen get a essential development.
