Description: The system is designed to grade raw cashew nuts before steaming or before feeding into the shelling section.

Working principle:

• It features a single grading drum divided into multiple sections with different mesh sizes, enabling separation into various size grades within one integrated system.
• After feeding, the material moves along the grading drum; smaller nuts fall into their respective sections, while larger nuts continue to the final discharge outlet.

Purpose:

• Ensure uniform size feeding
• Improve steaming and shelling efficiency
• Stabilize the overall production line
