The function of the observation hole on the vibrating screen

The vibrating screen observation hole is designed with some vibrating screens according to user requirements. Its function is mainly to check the movement status of materials on the screen surface and whether the screen mesh is intact. Once the material screening status is abnormal, you can check whether the screen surface is intact through the observation hole damaged.

Reasons for adding observation holes to vibrating screen

The vibrating screens used by some companies generally have a box-sealed structure. During the production process, users cannot fully understand the movement of materials on the screen surface. And whether the screen mesh is intact. After a fault occurs, it is difficult for users to find the problem and they need to inspect the equipment. We may waste a lot of time in finding and eliminating the cause of the fault, affecting production efficiency. Therefore, in the process of using the vibrating screen, the sealing structure of the user body is not good. The user can not understand the screening status of the screen surface in time, which greatly affects the product quality.

To solve these problems, EVERSUN Machinery can design the vibrating screen box, dust cover, discharge port, and reserve observation holes. because these can facilitate users to inspect the internal components of the screen machine. It can also observe the thickness of the material layer on the screen surface. And check whether there is an accumulation or screening status.

The installation position of the observation hole

We usually design observation holes at three locations: the box, the dust cover, and the discharge port. For rotary vibrating screen and linear vibrating screen, we mainly design it on the dust cover. Because it reduces the impact of the observation hole position on the sealing performance of the equipment. But there are also ones designed at the discharge port. For large swing screens, we often mainly locate the observation holes in the screen frame. This is mainly due to the high height of the model, and the design of the dust cover is not conducive to personnel checking the screen surface through the observation holes. The observation hole designed in the vibrating screen can not only reduce the equipment failure rate but also effectively control the screening quality of the product.
