Abstract: A cement clinker storage with diameter 70 meters adopts reinforced concrete silo structure and the truncated cone-shaped roof adopts double-layer spatial grid structure with bolt-sphere joints. The system selection, loads, material and design parameters were introduced and several key issues such as the horizontal load of clinker drag chain conveyor, clinker temperature, fatigue caused by vibration were discussed. The static analysis and dynamic characteristics analysis were conducted to obtain the mechanical characteristics of the large diameter silo roof structure. Points for attention in the phases of design, manufacture, installation and use were proposed.
Keywords: clinker silo roof; horizontal load of clinker drag chain conveyor; clinker temperature; equipment vibration; fatigue
