Cone Crusher Pinion

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

Cone Crusher Gear

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.

Cone Crusher Feed plate

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.

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.

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.
