The Symons cone crusher is renowned for its reliable structure, stable performance, and high crushing ratio. It utilizes a conical moving cone and a stationary cone with an adjustable gap to achieve progressive crushing of materials. As an upgraded version of the spring cone crusher, it features a unique layered crushing principle and a hydraulic adjustment system, making it widely used in the secondary and tertiary crushing stages of medium-to-high hardness ores (such as granite and iron ore), while simultaneously achieving a uniform output particle size. It is particularly suitable for applications requiring strict particle size control, such as in mining plants, aggregate production lines, and metal ore processing industries.
The Symons cone crusher is an upgraded and optimized version based on the spring cone crusher. It is a core medium and fine crushing equipment for medium to large-scale mines and aggregate production. It utilizes a unique lamination crushing principle, using the gyratory motion of the moving cone to compress and grind the material, producing finished products with excellent particle shape and reasonable gradation. It is especially suitable for processing materials with medium to high hardness, such as gold, diamonds, copper, manganese, iron ore, granite, basalt, andesite, pebbles, and other minerals, rocks, or aggregates. The Symons cone crusher features a distinctive spring overload protection system, effectively handling foreign objects in the crushing chamber and ensuring long-term stable operation. It is a high-performance and reliable crushing equipment option with excellent cost-effectiveness.
Compared to other cone crushers, the Symons cone crusher uses a spring + hydraulic composite protection system, resulting in lower maintenance costs. It can be integrated into fixed production lines or mobile crushing plants, and is particularly suitable for high-quality aggregate production. By changing the liners, it can switch between various cavity types, including standard (medium crushing), medium (medium-fine crushing), and short-head (fine crushing), meeting the particle size requirements of different crushing stages. It is a robust and reliable piece of core equipment in mining and aggregate production lines.
Spring Protection Device:
Heavy-duty spring sets are evenly distributed around the machine frame to provide mechanical overload protection.
Hydraulic Adjustment Mechanism:
The position of the stationary cone is changed by rotating the adjustment ring, allowing for hydraulic cavity cleaning and flexible adjustment of the discharge opening.
Transmission System:
Composed of a horizontal shaft, gear set, and eccentric sleeve, it is responsible for converting the motor's power into the gyratory motion of the crushing cone.
Machine Frame:
Made of heavy-duty cast steel, it bears the entire weight of the equipment and the crushing force, ensuring structural stability.
1. Multiple cavity types are available: By replacing the movable and stationary cone liners, you can quickly switch between three cavity types: standard (medium crushing), medium (medium-fine crushing), and short-head (fine crushing), meeting the needs of different crushing stages.
2. Lamination crushing principle: Using a full-feed method, the material is crushed by mutual compression within the crushing chamber, resulting in a product that is mostly cubical in shape with a low content of needle-like and flaky particles.
3. High crushing ratio: Laminated crushing technology ensures a high degree of fineness in a single crushing step, reducing the amount of recycled material.
4. Spring overload protection: The mechanical iron overload protection device has a simple structure and quick response, effectively preventing foreign objects from damaging the main machine, resulting in a long average time between failures for the equipment.
5. Stable operation: The independent thin oil lubrication system ensures sufficient lubrication of the bearings, effectively extending the service life of core components.
6. Wide range of applications: the Symons cone crusher can process various hard materials, from iron ore to basalt, and is suitable for both stationary crushing production lines and mobile crushing plants, meeting the needs of mining, infrastructure construction, and many other scenarios.
The core working principle of the Symons cone crusher is the eccentric sleeve-driven gyratory crushing mechanism combined with a spring overload protection system. During operation, the motor drives the horizontal shaft to rotate, and through gears, the eccentric sleeve causes the movable cone to perform an eccentric gyratory motion. Material fed from the top inlet falls into the crushing chamber and is gradually crushed to the target particle size through the layered crushing action between the movable cone and the stationary cone liner, eventually being discharged from the bottom. The hydraulic system can adjust the discharge opening size in real time to control the product particle size.

It is primarily suitable for materials with medium to high hardness, including iron ore, copper ore, granite, basalt, and pebbles. They are widely used in metal mining, aggregate production, and other fields. While they can efficiently process softer materials, from a cost perspective, they are more recommended for hard rock crushing applications.
The advantages of Symons cone crushers lie in their simple structure, low maintenance costs, low investment threshold, and extremely high operational stability. They are particularly suitable for users who require high equipment reliability and have relatively limited budgets. They offer outstanding cost-effectiveness in medium and fine crushing applications and are ideal crushing equipment for large mines and aggregate plants.
By using the discharge opening adjustment system at the top of the equipment, rotating the adjustment ring will raise or lower the stationary cone assembly, thereby changing the size of the discharge opening.
27-1450 TPH (tons per hour). The specific capacity is affected by factors such as material hardness, feed size, cavity type selection, and discharge opening size. Specific parameters need to be adjusted based on actual working conditions.
Yes. The Symons cone crusher can be integrated into a mobile crushing plant, combined with jaw crushers, vibrating screens, feeders, and other equipment to form a complete mobile crushing production line. It is suitable for engineering projects that require flexible relocation.
We recommend a length and width of at least 1.5 times the equipment dimensions. Please refer to the equipment parameters above. The height should take into account space for lifting and maintenance; please contact our professional engineers for a customized solution.
