Extending the service life of cone crusher wear parts hinges on reducing ineffective wear, avoiding abnormal damage, and optimizing the stress environment. Key measures include five aspects: First, pre-treat materials—remove impurities with magnetic separators and screens, and control feed particle size/moisture to prevent blockage. Second, optimize operating parameters: limit capacity to 80%-95% of the design value, adjust crushing gaps by material hardness, and ensure uniform feeding. Third, manage the lubrication system strictly—use suitable oil/grease, replace oil every 2,000-2,500 hours, and monitor oil level/temperature. Fourth, follow operating/maintenance norms: avoid loaded start-stop, inspect parts regularly, and ensure proper installation with calibrated concentricity. Fifth, select quality parts—use high-chromium cast iron for core wear parts and alloy steel for transmission components, with optimized heat treatment and precision machining.

There are various types of cone crushers, each with its own unique characteristics. Simons cone crusher is the most commonly used one in the world. It is inexpensive, has stable performance, and has a wide range of operation and maintenance experience. However, its structure is bulky, its crushing force is small, its output is low, and its iron-passing function is unreliable. It has gradually been replaced by more advanced models. Domestic manufacturers have added a hydraulic cavity clearing function to form a composite type.

There are various types of cone crushers, including single-cylinder cone crusher, multi-cylinder cone crusher, full hydraulic cone crusher, compound cone crusher, etc. The feed size of single-cylinder cone crusher can reach 560mm, and the production capacity is 45-2130 tons/hour. The feed size of multi-cylinder cone crusher can reach 350mm, and the production capacity is 45-1200 tons/hour.

GP cone crusher has the characteristics of advanced structural design, excellent crushing capacity, excellent reliability and low production and operation cost. The hydraulic cone crusher can realize multiple functions such as discharge port adjustment, cavity cleaning, iron overload protection, etc. by lifting the moving cone with a single hydraulic cylinder; it is equipped with an electronic intelligent discharge port control system to realize more production process control and operation optimization functions. Single-cylinder hydraulic cone crusher can be widely used in various black, non-ferrous, non-metallic mines and sand and gravel industries.

The SYMONS cone crusher is a modern high-performance crusher designed and developed based on the lamination crushing principle and the concept of more crushing and less grinding, which integrates high swing frequency, optimized cavity type, and reasonable stroke, according to the needs of customers on the basis of introducing and absorbing foreign technologies.

During the use of cone crusher, due to the wear of parts in the ore crushing process, the wear will be aggravated, the equipment efficiency will decline and the service life will decline if maintenance is not carried out, so its maintenance is very important. During the maintenance, the following issues should be paid attention to:
