Cone Crusher torch ring

This paper details the cone crusher torch ring, a vital sealing and protective component situated between key assemblies like the adjustment ring and main frame, or moving cone and fixed cone. Its primary functions include high-temperature sealing (withstanding up to 150°C), preventing contamination, thermal insulation, and vibration absorption, requiring heat resistance, oil resistance, and mechanical strength. The torch ring has a composite structure, consisting of a metal framework (low-carbon or alloy cast steel) with a U/L-shaped cross-section, a sealing liner (high-temperature rubber, graphite composite, or metal-reinforced felt), retention grooves, flange edges, and optional vent holes. The metal framework is produced via sand casting: material selection (Q235 or ZG230–450), pattern making with shrinkage allowances, green sand molding, melting and pouring (1450–1480°C), cooling and shakeout, and annealing for stress relief. The machining and manufacturing process involves framework machining, sealing liner preparation, liner bonding with heat-resistant adhesive, finishing, and optional surface treatment. Quality control includes material testing (chemical composition, tensile strength, hardness), dimensional checks (CMM for accuracy), bond strength testing, seal performance evaluations (pressure and heat cycling), and visual/functional inspections. These ensure the torch ring provides reliable sealing in high-temperature, high-vibration conditions, safeguarding internal components and ensuring efficient crusher operation.

Cone Crusher Hopper

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.

Cone Crusher locking nut

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.

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.
