Banana screen is a commonly used screening equipment in mine production. It has the characteristics of small volume, light weight, high efficiency and many layers. In the production, some users will find their banana sieve material running off, do not go, no material phenomenon, very affect the production. This article shares the reason and solution of material running off in banana screen.
1. Improper installation of vibration motor
Due to the banana screen of material transport screening is through the vibration source body, that is, the vibration motor to material a good design of fixed direction of the fixed size of the vibration force pushed, therefore, when the poor feeding situation, basically can be judged as the installation Angle of the vibration motor out of the problem.
2. Equipment heavy workload, long running time
There is a limit to the amount of work that humans and equipment can take every day. People who work for a long time will get tired or even get sick, and equipment will fail. Relative to the large banana screen, due to its heavy weight, if coupled with the large batch screening work for many years, some parts of the body will be loose because of this long time of repeated vibration and strong inertia, which may lead to the change of vibration motor angle, the phenomenon of material running off.
3. Not feeding evenly as required
The instructions for banana screen repeatedly mention the requirement of uniform feeding. Because if the feed when more or less, it is easy to cause the screening accuracy is not stable, and due to the amount of material caused by the material force deviation is large, there is a material biased to the side of the problem
4. The shock absorption spring and other parts of the screen body are aging and loose
Except the vibration motor provide the main screening source power for banana screen, the existence of damping banana screen damping spring, bouncing ball, sealing apron, more or less also affect the vibration screen force and banana screen body level stability.
If a part of the aging and other problems, due to the uneven screen surface of the banana screen machine instability, resulting in the direction of the material, serious when there will even be a sudden noise, banana sieve wear serious life greatly reduced and other problems. Therefore, it is necessary to carry out regular inspection and maintenance of the equipment. In addition, the materials used for parts and components are also crucial.
