AI Technical Summary
Existing rotary kiln tire limit devices for cement production are prone to weld cracking and cylinder deformation during operation, affecting the stable operation of the equipment. Furthermore, traditional designs cannot effectively control the amount of tire slippage.
Two sets of positioning mechanisms are arranged in parallel and staggered along both sides of the tire. The gap between the positioning component and the side of the tire is set to form an equally divided retaining ring limit, which ensures that the tire is positioned in a reasonable position and limits the amount of deflection, thus avoiding cracking of the integral retaining ring weld.
It effectively avoids cracking of the integral retaining ring weld, ensures the stable operation of the rotary kiln system, reduces cylinder deformation and refractory material damage, and improves the reliability of the equipment's cycle operation.
