Wear-resistant Material: The ring die is made of high-quality alloy steel using a special heat treatment process. It boasts high surface hardness and strong wear resistance, allowing it to withstand high-speed friction from feed, grain, and fertilizer granules for extended periods, thus extending its service life.

Processing Technology: Advanced CNC machining and precision boring processes ensure uniform die diameter and stable die shape, guaranteeing uniform granule forming and dimensional stability, effectively improving production efficiency.

Corrosion Resistance: The ring die surface undergoes anti-corrosion treatment to address the chemical composition and humidity changes during the drying process of organic compound fertilizers and grains, maintaining stable performance over the long term and reducing maintenance frequency.

Applications: The ring die can be widely used in various industrial equipment such as feed machinery, grain drying and storage equipment, and organic compound fertilizer production lines, meeting the pressing and forming needs of different materials.

Structural Design: A reasonable die layout and wall thickness design ensure high stability under high load operation, smooth material discharge, reduced material blockage and breakage, and improved overall equipment capacity.

Maintenance and Replacement: The ring die has a compact structure, is easy to install and disassemble, and can be quickly replaced or adjusted, reducing equipment downtime and improving production continuity and economic efficiency.

Energy Saving Performance: Precision machining and uniform die design effectively reduce frictional resistance, making the equipment run more smoothly, reducing energy consumption, and ensuring the quality of pellet forming.
