AI Technical Summary
In roller kilns, long-term friction between saggers and rollers causes deviation and collisions, affecting production efficiency and posing safety hazards. Furthermore, insufficient contact area between the atmosphere and materials during sintering makes it difficult to discharge waste gas in a timely manner.
The design incorporates a concave-convex structure for the sagger and rods, ensuring a tight fit and providing a unique operating path. This guarantees a fixed spacing and air contact area between the saggers, and the groove design facilitates rapid exhaust of exhaust gases.
To avoid sagging and collisions in the sagger, improve production efficiency, ensure smooth chemical reactions, reduce safety risks, and enhance material performance.
