At present, there are many questions with the vibrating screen. The main parts of the vibrating screen are replaced frequently. Especially the sieve plate and the sieve frame part, however, when there is a problem in one of the components, the screening effect of the entire vibrating screen will be affected. When the sieve plate is used for too long, the sieve hole will be seriously damaged. Wear, once the screen holes are worn, the entire screening work will be affected, so the product size will be inflexible and the production cost will be relatively high.

The structural strength of the material can not meet the requirements. At present, there are still many gaps in the research on materials between China and foreign countries, so that the life of domestic high-frequency vibrating screen is generally lower. At present, the life of domestic high-frequency vibrating screen is generally 3 to 5 years, while that of foreign countries is about 8 years, resulting in an increase in production costs and a waste of resources.

In the design process, due to the lack of understanding of the structural strength of each component, it is easy to cause stress concentration in production, resulting in side plate, supporting beam, sieve plate and other fracture phenomena, affecting the normal production activities.
The reliability is relatively poor, which is mainly manifested in the high failure rate of the key components such as screen frame, vibration exciter and so on. Because the vibrating screen works in several links of the washing process system, these failures will certainly cause the whole process system to stop.
