Description

Technical Field

[0001] The utility model relates to the technical field of screening, and more particularly to a multi-stage screening device for perlite processing. Background Art

[0002] Perlite is a natural volcanic rock widely used in construction, insulation, agriculture and other fields. During the processing, multi-stage screening devices are crucial to improving the quality and grading efficiency of perlite products.

[0003] In the existing technology, firstly, some devices are unable to finely separate materials of different particle sizes, resulting in low screening efficiency. Without multi-stage screens, the required screening accuracy may not be achieved, affecting the quality of the final product. Single-stage screening may not be able to handle large amounts of materials, limiting the improvement of production capacity. Without diversion buckets and bottom buckets, materials may directly impact the screen, accelerating the wear of the screen. Secondly, the replacement of the screen in some devices will become complicated and time-consuming, increasing downtime. The difficulty in replacing the screen will lead to increased maintenance costs because it requires more time and labor. The long screen replacement time will lead to more downtime in the production process, reducing overall production efficiency. There is no quick clamping mechanism, and manual operation may be required when replacing the screen, increasing operational risks. Utility Model Content
