Swing screen is a highly acclaimed precision screening equipment extensively utilized in industries requiring the screening of fine powder materials. It boasts a versatile screen that can be easily replaced, offering utmost convenience. The enclosed structure of the swing screen ensures a dust-free screening process, making it a preferred choice among the majority of users. However, during its usage, we have encountered occasional issues regarding the overheating of bearing temperatures. To identify the underlying cause of this overheating, further investigation is required.
After conducting thorough analysis and research, it has been discovered that the bearing temperature is excessively high. This is primarily caused by the rapid increase in temperature of the bearing, leading to excessive thermal expansion of its components. Consequently, the working clearance of the bearing decreases, resulting in significant friction. Additionally, bearing overheating can also be attributed to the improper selection of lubricants, insufficient lubrication and heat dissipation, as well as contamination of the bearing's working environment. Insufficient bearing oil supply, excessive or insufficient oil injection, or contamination of the bearing oil can further exacerbate the issue, potentially causing damage to the bearing in severe cases.
It's important to address the issue at hand by taking reasonable steps. One solution is selecting the appropriate grease, which can counter high frequency transient impact stress during lubrication, thus lowering bearing temperature. Alternatively, choosing the right bearing is another option. Vibrating screens require bearings that can endure high frequency vibration loads, which are always fluctuating. Without using the proper bearings, the radial clearance of the bearing will be too small.
The screen swing mechanism has the ability to transfer material across the screen, resulting in improved productivity and a cleaner screening process. This technology is ideal for screening fine, voluminous, and challenging materials that are difficult to screen.
The reduction gear mounted on the bottom plate propels the transfer brush in rotary brush cleaning. This brush spins the net cleaning material positioned beneath the mesh, making it ideal for screening materials with a spherical, crystalline, or brittle composition.
When it comes to cleaning bouncing balls, it's important to use rubber and silicone balls that meet food grade standards. These balls are designed to jump on the punching plate located at the bottom of the screen and hit the metal mesh. This action helps to reduce the blockage of the mesh, ensuring that it stays clean and clear for optimal performance. By using these specialized balls, you can rest assured that your screen will remain in top shape and continue to function at its best.
