Many industries, particularly material processing, mining, food, and chemical, all utilise vibrating screens to effectively classify and separate materials. Generally, vibrating screens are comprised of numerous screen surfaces to ensure that materials can be separated by size, shape, and density. These screening elements may be flat or slightly curved depending on the type of vibrating screens. They can likewise come in metallic or nylon wire mesh, metal sheets with perforations, and other form factors.
Vibrating screens normally work by allowing materials of different sizes, shapes, and density to enter the screen surface. Some parts of these materials will then be in contact with the said surface, forming a material layer that will be loosened during the movement of the screens. Small particles are subsequently sent to the lower layer, separating them from the rest of materials that are larger in size. The vibrating process continues until coarse and fine-grained materials are separated accordingly.
With the proper use of vibrating screens, they can easily yield results that can be helpful to various industries. To maximise vibrating screen efficiency, here are some rules that you may want to follow.
Choose the Right Screen Media
The type of screen media that is being installed for vibrating screens can affect their overall performance and efficiency. While a lot of businesses turn to the same media when it comes to their vibrating screens, their purposes and applications vary. Therefore, you must choose a screen media that could yield great results without any compromises in terms of vibrating screen’s service life.
Increase the Screening Area
Another rule that can increase the vibrating screen efficiency is to manage the number of products on the screen surface. If the materials on the screen surface have reached about 80% of the screen’s capacity, then the efficiency of the vibrating screen has already reached its peak. Keeping the volume of materials at or below this percentage would increase the screening area, improving efficiency along the way.
Optimise the Feeding Process
One more effective rule to make vibrating screens efficient is to optimise your feeding process. The materials that will be fed onto the screening equipment should be spread as widely as possible. This way, the maximum width of the screen, as well as the total screening area, can be significantly maximised. Additionally, the materials should not be segregated beforehand to avoid any inconsistencies.
Look Out for the Correct Angle
Some industries utilise vibrating screens with large dip angle. While these vibrating screens allow faster movement of materials on the screen surface, the overall efficiency of the screening process remains low. One rule to remember when it comes to the angle of your vibrating screen is to sustain its angle at around 15°, ensuring that the materials will be screened effectively.
