Cone Crusher

Yuexin Machinery's cone crushers have a wide range of applications, easily handling the crushing needs of various medium-hard and higher hardness ores such as granite, basalt, and iron ore. Whether it's the coarse crushing of high-hardness rocks or the medium-fine crushing of medium-hardness ores, it demonstrates strong crushing capabilities.

Compared to traditional crushers, the cone crusher has particularly outstanding performance advantages. It not only has a large crushing ratio, efficiently crushing large pieces of ore to the required particle size, but also produces products with superior particle shape, regular particle shape, and reasonable gradation, meeting subsequent production requirements without additional shaping processing. In terms of efficiency and cost control, this equipment also performs exceptionally well, increasing production efficiency by over 30% compared to traditional equipment. It significantly shortens the operating cycle and increases output capacity. Simultaneously, operating costs are reduced by 20% through optimized energy consumption design and reduced wear on vulnerable parts, effectively lowering production inputs for enterprises.

Product Feature And Application

The core advantages of the cone crusher lie in its breakthroughs in both crushing efficiency and intelligent control. It employs an advanced layered crushing principle, where ore undergoes multiple compressions and grinding processes upon entering the crushing chamber, resulting in a more thorough and efficient crushing process far exceeding that of traditional crushing equipment. This crushing method not only significantly increases production capacity but also optimizes finished product quality, producing aggregates with regular cubic particle shapes and less than 5% needle-like and flaky content, meeting high-standard production requirements without the need for additional shaping.

The cone crusher excels in durability and adaptability to various working conditions. Its core wear-resistant components—the crushing wall and the jaw wall—are made of high-chromium alloy and strengthened through a special heat treatment process, improving wear resistance by 50% compared to ordinary components. This design significantly extends the service life of wear parts, reduces the frequency of equipment downtime for component replacement, and substantially lengthens the maintenance cycle, effectively controlling overall operating costs. Simultaneously, it possesses exceptional environmental adaptability, capable of stable continuous operation in complex conditions ranging from -20℃ to 50℃. Whether in frigid regions or hot and humid environments, it maintains stable crushing performance without requiring frequent adjustments or maintenance.

Thanks to its superior comprehensive performance, the cone crusher's applications cover multiple core industries, making it a core piece of equipment for large-scale crushing production. In the metal mining sector, it is perfectly suited for the secondary and tertiary crushing stages of various metal ores, such as copper, iron, and zinc ores. In the construction aggregate processing sector, it can efficiently process raw materials such as granite and limestone, producing sand aggregates that meet construction standards. In the large-scale infrastructure sector, whether it's the crushed stone processing required for high-speed rail and highway construction or the raw material preparation for water conservancy projects, its high capacity and low loss advantages comprehensively meet the efficient and large-scale crushing needs of different industries.

Production Details

1. Crushing Chamber Details: Showcasing the internal structure of different chamber types (standard chamber, short-head chamber), illustrating their adaptability to different process requirements of "coarse crushing, medium crushing, and fine crushing," and visually demonstrating the crushing path of the ore within the chamber.

(Standard Chamber): Demonstrating the internal structure of a standard chamber cone crusher. The crushing chamber space is relatively large. After the ore enters from the top, it undergoes preliminary crushing in the larger gap area between the moving and fixed cones. The crushing path is relatively "coarse," suitable for coarse and medium crushing processes, capable of handling larger ore particles, providing a foundation for subsequent crushing stages.

(Short-head Chamber): The short-head chamber has a smaller crushing chamber gap. After entering, the ore is repeatedly squeezed and ground in a more compact space, resulting in a "fine" crushing path. It can crush the ore into smaller particles, suitable for fine crushing processes, producing finished aggregates with better particle shape and lower needle-like and flaky content.

By comparing these two chamber types, one can intuitively see how the cone crusher achieves efficient grading and crushing of ore according to different process requirements of "coarse crushing, medium crushing, and fine crushing."

2. Hydraulic System Details: Close-up shots of the hydraulic cylinders and control valve groups explain the working principles of "automatic chamber clearing, overload protection, and discharge port adjustment," highlighting the equipment's intelligence and safety.

Automatic Chamber Clearing: When the crushing chamber needs cleaning due to material blockage or machine shutdown, manual entry into the dangerous chamber is unnecessary. After the operator issues the clearing command, the solenoid directional valve in the control valve group switches the oil circuit, and hydraulic oil is quickly injected into the cylinder, pushing the piston to rapidly descend the moving cone, instantly widening the gap in the crushing chamber. Simultaneously, the one-way throttle valve controls the oil flow rate, preventing the moving cone from descending too quickly and impacting the equipment. After the blocked material is discharged, the accumulator releases pressure, the hydraulic oil flows back, and the moving cone smoothly resets. The entire process is completed automatically, ensuring personnel safety and improving chamber clearing efficiency.

When uncrushable materials such as iron blocks are mixed into the ore used for iron protection, the pressure inside the hydraulic cylinder rises sharply due to the compression of the moving cone. At this time, the pressure sensor in the control valve assembly quickly detects the abnormal pressure signal. When the oil pressure exceeds the set threshold (usually 5MPa), the one-way valve quickly opens, allowing hydraulic oil to flow into the accumulator and compress the internal ammonia gas. The cylinder then drives the moving cone downwards, increasing the discharge port and allowing the iron blocks to be discharged smoothly. After the iron blocks are discharged, the ammonia gas in the accumulator applies reverse pressure, causing the hydraulic oil to flow back, and the moving cone slowly resets under the buffering effect of the one-way throttle valve. This process requires no manual shutdown, and the relief valve provides secondary pressure relief in case of excessive pressure, providing double protection to prevent equipment damage due to overload.

For discharge port adjustment, if the discharge particle size needs to be adjusted, first, the pressure of the locking hydraulic cylinder is unloaded through the control valve assembly, loosening the sawtooth thread of the fixed cone. Then, the control valve pushes the hydraulic cylinder to rotate the adjusting ring, causing the fixed cone to rise or fall through the threaded transmission. When the discharge opening needs to be reduced, the control valve assembly pumps hydraulic oil into the lower part of the cylinder, pushing up the moving cone; when the discharge opening needs to be increased, some hydraulic oil is discharged to lower the moving cone. Changes in the oil level in the tank reflect the size of the discharge opening, and the dimensions can be accurately read using a scale. After adjustment, the shut-off valve is closed to seal the oil circuit and maintain a stable discharge opening. This adjustment method eliminates the need to disassemble the equipment, achieving precise and efficient control of the discharge particle size, adapting to different process requirements, and demonstrating the advantages of intelligent operation.
