This paper elaborates on the Cone Crusher Hopper component, a crucial material guiding part located at the top of the crusher. Its main functions include material collection and storage, uniform distribution, impact buffering, and contamination prevention, requiring high wear resistance, structural strength, and corrosion resistance. The hopper is typically funnel-shaped or rectangular, composed of the hopper body, feed grate/screen, wear liners, reinforcing ribs, mounting flange, access door, and optional vibration device mounts, each with specific structural features and roles. For cast steel variants, the casting process involves material selection (high-strength cast steel like ZG270–500), pattern making, molding, melting and pouring, cooling and shakeout, heat treatment, and casting inspection. Most hoppers, however, are fabricated from steel plates through plate cutting, forming and bending, welding assembly, post-weld treatment, machining of mounting features, liner installation, and surface treatment. Quality control processes cover material validation, dimensional accuracy checks, weld quality inspection, structural integrity testing, liner performance testing, and final inspection. These ensure the hopper can withstand abrasive wear and impact, guaranteeing continuous and efficient operation of the cone crusher in relevant applications.

This paper provides a detailed introduction to the locking nut component of cone crushers. As an important fastening component, it is mainly used to secure key assemblies such as the main shaft, fixed cone liner, or adjustment ring. It can realize functions including secure fixation, load distribution, and maintaining the crushing gap in cooperation with the adjustment ring. Its composition and structure include the nut body, threaded bore, locking mechanism (such as locking holes, set screws, and tapered surfaces), flange or shoulder, and wrench flat faces, with each part having a specific design and function. In terms of casting process, large-sized locking nuts often use gray cast iron, ductile iron, or cast steel, going through steps such as material selection, pattern making, molding, melting and pouring, cooling and cleaning, and heat treatment. The machining and manufacturing process covers steps like rough machining, machining of locking features, finish machining, surface treatment, and assembly with locking components. Quality control includes measures such as material testing, dimensional accuracy checks, thread quality inspection, locking performance testing, and non-destructive testing, ensuring that the component has good wear resistance, anti-loosening performance, and structural rigidity in high-vibration environments, thus guaranteeing the stable operation of the crusher.

This paper provides a detailed overview of the cone crusher pinion, a critical transmission component that meshes with the bull gear to transfer motor power to the eccentric assembly, enabling the moving cone's oscillating motion. It elaborates on the pinion's functions, including power transmission, torque amplification, and precision meshing. The composition and structure are detailed, consisting of gear teeth, shaft body, bearing journals, shoulders/collars, lubrication holes, and keyway/spline, along with their structural characteristics. For large-scale pinions, the casting process is described, covering material selection, pattern making, molding, melting and pouring, cooling and shakeout, heat treatment, and inspection. For forged pinions, the machining and manufacturing process is outlined, including forging, rough machining, heat treatment, finish machining, and deburring/polishing. Additionally, quality control measures are specified, such as material validation, dimensional accuracy checks, hardness and microstructure testing, dynamic performance testing, non-destructive testing, and final inspection. These processes ensure the pinion achieves the required strength, precision, and durability, guaranteeing reliable power transmission in demanding crushing operations

This paper provides a detailed account of the cone crusher gear, a core transmission component that transfers motor power to the eccentric shaft, driving the moving cone's oscillation. It fulfills key roles in power transmission, speed regulation, and torque amplification, requiring high strength, wear resistance, and precision. The gear's composition and structure are outlined, including the gear body (alloy steel, solid or hollow), teeth (involute profile with specific parameters), bore/shaft connection, hub/flange, lubrication grooves, and webs/ribs for large gears. For large bull gears, the casting process is detailed: material selection (ZG42CrMo), pattern making, molding, melting, pouring, cooling, and heat treatment. The machining process covers rough machining, tooth cutting (hobbing or shaping), hardening heat treatment (carburizing, quenching, tempering), finish machining (grinding), and deburring. Quality control measures include material testing (chemical analysis, tensile and impact tests), dimensional checks (CMM, gear measuring center), hardness and microstructure testing, dynamic performance testing (mesh and load tests), and non-destructive testing (MPT, UT). These ensure the gear meets precision, strength, and durability requirements, guaranteeing reliable operation in heavy-duty crushing scenarios.

This paper elaborates on the cone crusher feed plate, a key component in the material feeding system located at the top of the crusher's feed inlet. It functions to guide material flow, prevent backspray, reduce impact stress, and control feed rate. The component's composition and structure are detailed, including the plate body, mounting flange or bolt holes, impact-resistant liner, baffle plates (in some designs), reinforcing ribs, and chute or inclined surface, along with their structural features. For high-chromium cast iron variants, the casting process is described, covering material selection, pattern making, molding, melting, pouring, cooling and shakeout, heat treatment, and inspection. For steel plate variants, the machining and manufacturing process is outlined, including plate cutting, bending and forming, welding of reinforcements, surface treatment, and liner installation. Additionally, quality control measures are specified, such as material validation, dimensional accuracy checks, weld quality inspection, impact and wear testing, assembly and function testing, and final inspection. These processes ensure the feed plate has high impact resistance, wear resistance, and dimensional accuracy, guaranteeing reliable material feeding and protection for the cone crusher in heavy-duty operations.

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.
