Technical Field

[0001] This utility model relates to the field of crusher buffer bin liner maintenance technology, and in particular to a suspension bracket device for crusher buffer bin liner. Background Technology

[0002] Currently, crushers are one of the main crushing equipment in mining enterprises. Crushers are mainly used for coarse crushing of ores and rocks. The crusher's buffer bin liners, subjected to impact and erosion from ore and rock materials, frequently require replacement. Replacement necessitates cutting all welds on the fixing liner to remove the liner after its service life is limited. Then, the new liner is aligned and welded in place. During replacement, because the liner is a high-manganese steel casting, each liner has a large mass and bears the impact and wear of materials. The exposed fixing welds experience severe wear, requiring a large amount of welding. Furthermore, the confined space makes it difficult for welding and cutting fumes to dissipate, making the replacement process time-consuming and labor-intensive, significantly impacting production efficiency, reducing equipment operating efficiency, and significantly increasing the workload of maintenance workers. To improve operational efficiency and reduce labor intensity, we have implemented technical improvements to solve the difficulties in fixing and replacing crusher buffer bin liners. Based on the above, we have developed a custom-made crusher buffer bin liner suspension bracket. Utility Model Content
