Cone Crusher Ring Seal

This paper details the cone crusher ring seal, a critical sealing component installed between the adjustment ring and frame or moving and fixed cone assemblies, functioning to prevent contamination, retain lubricants, and maintain pressure balance. It outlines its composition, including the seal body (rubber with embedded metal reinforcement ring), lips/sealing edges, metal reinforcement ring, mounting features, and vent holes (in some designs), along with their structural characteristics. The manufacturing process is elaborated, covering material preparation, molding (compression or injection), vulcanization, and trimming. It also describes machining of the metal reinforcement ring, seal assembly preparation, and installation steps. Additionally, quality control measures are specified, such as material testing, dimensional accuracy checks, sealing performance testing, environmental and durability testing, and visual/defect inspection. These processes ensure the ring seal provides reliable sealing, protecting internal components and extending the crusher’s service life in harsh environments.
