Cone Crusher Adjustment Ring

This paper elaborates on the adjustment ring of cone crushers, a key component at the top of the fixed cone assembly that adjusts the crushing gap to control discharge material size and supports the fixed cone liner while housing safety devices. It details its composition, including the ring body, fixed cone liner mounting surface, adjustment gear teeth/threads, hydraulic cylinder ports/spring chambers, lubrication channels, sealing grooves, and locking mechanism, along with their structural features. The casting process for the ring body is outlined, covering material selection, pattern making, molding, melting, pouring, heat treatment, and inspection. It also describes machining and manufacturing processes (rough machining, stress relief annealing, finish machining, surface treatment, assembly) and quality control measures (material validation, dimensional accuracy checks, functional testing, wear resistance testing, final inspection). These processes ensure the adjustment ring provides accurate gap adjustment and reliable protection for cone crushers in demanding applications.
