Shenyang Shilong Mechanical, with over 20 years of experience in the crusher industry, has earned a solid reputation in both domestic and global markets. Its CH440 cone crusher, as a high-performance medium-to-fine crushing equipment, integrates advanced technologies to meet the demands of complex mining and aggregate production. Below is a detailed introduction to the crusher’s advantages, functions, as well as Shenyang Shilong’s manufacturing capabilities and quality assurance.
Advantages of the CH440 Cone Crusher
Outstanding Crushing Performance
The crusher adopts the lamination crushing principle, which enables it to squeeze, bend and impact hard materials such as granite and basalt efficiently. It achieves a product cubicity of no less than 85%, ensuring uniform and well-shaped particles that fully meet the quality requirements of construction aggregates and mining processing. With a capacity ranging from 68 to 413 t/h and a maximum feed size of 215 mm for the standard model, it balances high output and crushing efficiency, adapting to large-scale continuous operation scenarios.
Reliable Hydraulic Protection & Easy Adjustment
Equipped with a hydraulic control system consisting of multiple cylinders, the CH440 realizes flexible adjustment of the discharge port and reliable overload protection. When encountering iron blocks or uncrushable materials, the hydraulic system can quickly lift the moving cone to discharge the foreign objects, avoiding equipment damage. Additionally, the hydraulic adjustment mechanism allows operators to modify the discharge port within the range of 6 - 44 mm conveniently, adapting to different particle size requirements without complicated operations.
Durable Structure & Low Maintenance Cost
Key components of the CH440 are made of high-quality materials and precision-manufactured. The moving cone body is forged from 42CrMo alloy steel, and the liner uses CR20 wear-resistant material, which significantly extends the service life of vulnerable parts. The integrated cast steel main frame with radial reinforcing ribs enhances structural rigidity to withstand strong impact during crushing. Maintenance operations such as liner replacement can be performed from the top of the equipment, minimizing operational risks and reducing downtime for maintenance.
Strong Environmental Adaptability
The crusher is equipped with a high-performance lubrication and dustproof system that effectively prevents dust from entering the internal components, ensuring stable operation in dusty mining environments. It is widely applicable to mining, metallurgy, and aggregate production industries, and can handle various hard and abrasive materials stably, showing excellent adaptability to complex working conditions.
Functions of the CH440 Cone Crusher
Medium-to-Fine Crushing of Multiple Materials
As a core equipment for secondary and tertiary crushing, the CH440 is specialized in processing hard ores, rocks, and construction aggregates. It can be seamlessly integrated into crushing production lines, cooperating with jaw crushers and vibrating screens to complete the entire process from raw material crushing to finished product screening, which is essential for projects such as stone quarries and metal mine processing.
Intelligent Operation & Control
The crusher is compatible with intelligent control functions. It can be equipped with an electronic intelligent discharge port control system to realize real-time monitoring and adjustment of the crushing process. Operators can regulate parameters according to feed conditions, ensuring the equipment operates at optimal efficiency. The matching sensors and monitoring modules also help track the running status of key components, laying the foundation for predictive maintenance.
Comprehensive Safety Protection
Beyond overload protection, the hydraulic system also supports cavity cleaning and emergency shutdown functions. The independent lubrication system ensures sufficient lubrication of bearings and transmission parts, preventing excessive wear caused by friction and reducing the risk of equipment failure. This multi-layer protection design maximizes the safety and continuity of operation.

Its business scope also extends to related fields such as cement, power stations, and petroleum, involving the production of accessories like fracturing pump housings and crankshafts, demonstrating strong comprehensive manufacturing capabilities.
Quality Assurance of Shenyang Shilong
Strict Multi-Link Quality Control
The company implements rigorous quality inspection throughout the production process. Key components such as the main frame and eccentric shaft sleeve are made of high-quality cast steel like ZG 270 - 500 and undergo heat treatment to enhance mechanical properties. It adopts advanced testing methods including coordinate measuring machine (CMM) dimensional inspection, laser scanning, ultrasonic testing (UT), and magnetic particle testing (MPT) to detect material defects and dimensional deviations, ensuring each component meets precision standards.
Reliable Component & Process Quality
Core parts of the CH440, such as the moving cone and liner, are made of high-strength and wear-resistant materials like 42CrMo and CR20. The segmented fixed cone and forged moving cone undergo precision machining and strict performance testing, which improves the equipment’s stability and service life under long-term heavy-load operation.
Comprehensive After-Sales Service Support
