Description

Technical Field

[0001] This utility model relates to the field of grading wheel technology, specifically a split-type grading wheel that is easy to maintain. Background Technology

[0002] A classifying wheel is a widely used piece of equipment in industrial production, primarily used for classifying materials to separate them into different particle sizes. It plays a vital role in various fields such as mineral processing, chemical engineering, building materials, and food processing. However, traditional classifying wheel designs have some problems and shortcomings, which may lead to low classification accuracy, rapid equipment wear, high maintenance costs, and limited applicability in practical applications.

[0003] Traditional classifiers typically employ an integral structure, with the blades and rim designed as a single unit. While this design is simple, the entire classifier needs to be replaced when the blades wear or are damaged, resulting in high maintenance costs and time consumption. Furthermore, the integral structure is more complex to install and disassemble, increasing the difficulty of maintenance.

[0004] Traditional grading wheel blades are typically fixed to the rim by welding or bolting. Replacement is cumbersome and requires specialized tools and skills, especially if the blades are worn or damaged. Furthermore, blade replacement can cause rim deformation or damage, further affecting the grading wheel's performance. Therefore, a more easily maintained, split-type grading wheel is proposed to address these issues. Utility Model Content
