Multi-cylinder hydraulic cone crushers are specifically designed for secondary or tertiary crushing of high-hardness materials such as granite, iron ore, and basalt. It is widely used in mining, metallurgy, construction, chemical, and other fields. Its core feature is that it achieves automated control and efficient crushing through hydraulic adjustment of the discharge port and overload protection. Multi-cylinder hydraulic cone crushers are particularly suitable for applications requiring strict particle size distribution and continuous production, making them key equipment in modern mineral processing plants and aggregate production lines.
The multi-cylinder hydraulic cone crusher is a crushing equipment developed from the spring cone crusher. It replaces the traditional spring structure with multiple sets of hydraulic cylinders, achieving overload protection and intelligent adjustment of the discharge opening. It is particularly suitable for secondary or tertiary crushing of medium or high hardness ores, and for the medium and fine crushing stages of iron ore, copper ore, and gold ore. This equipment adopts a fixed-shaft structure design, combined with a layered crushing chamber, enabling multi-particle layered crushing. The crushed product has a uniform cubic particle size, a processing capacity of 90-1200 tons/hour, and a maximum feed particle size of 353mm, showing excellent processing results in iron ore fine crushing retrofit projects.
Compared to the single-cylinder hydraulic cone crusher, the multi-cylinder hydraulic cone crusher has a more complex structure, but its production capacity can be increased by approximately 90% when crushing hard rock, making it particularly suitable for the large-scale production needs of large mines. Through multiple sets of hydraulic cylinders for overload protection and discharge opening adjustment, it features higher crushing efficiency, more stable output particle size, and intelligent control capabilities.
Crushing Cone Section:
High manganese steel moving cone + fixed cone liner, modular design facilitates replacement of wear parts.
Multi-cylinder Assembly:
Circumferentially distributed hydraulic cylinders provide constant crushing force and support one-key reset.
Eccentric Sleeve:
It transmits power through the transmission part and drives the moving cone to make a gyratory motion. The size of its eccentricity directly affects the crushing stroke and processing capacity.
Transmission System:
Heavy-duty V-belt + reduction gear pair, transmitting greater torque.
1. High-efficiency crushing capacity: Adopting a large eccentricity and high swing frequency design, the processing capacity is 30%-50% higher than that of traditional spring cone crushers, and it is especially suitable for hard rock crushing.
2. High-quality finished aggregate: The laminated crushing chamber enables multi-particle crushing, resulting in uniform cubic particle size and a needle-like/flaky content of less than 10%, meeting the requirements for high-standard building aggregates.
3. Intelligent hydraulic system: The PLC touch screen allows for one-button adjustment of the discharge port size, and the iron overload protection device can automatically identify and discharge uncrushable objects, making the equipment safer to operate.
4. Low operating costs: The moving and fixed cones are made of high-manganese steel, and the thickened liner design extends service life by 20%. The side-disassembly structure facilitates maintenance and reduces downtime.
5. Energy-saving and environmentally friendly: The optimized cavity design reduces crushing energy consumption; the labyrinth-type sealing structure reduces dust leakage and meets green crushing operation standards.
6. Heavy-duty adaptability: Utilizing high-manganese steel composite liners, the service life is extended by 2-3 times. It can withstand greater crushing forces and maintain stable operation even under harsh working conditions.
7. Flexible configuration options: Covering various cavity types such as coarse, medium, fine, and ultra-fine, to meet the needs of different materials and production capacity.
The multi-cylinder hydraulic cone crusher operates based on the dual core technologies of “layered crushing” and “hydraulic protection.” The motor drives the eccentric sleeve to rotate via a pulley, and the moving cone, driven by the eccentric sleeve, performs a gyratory motion, forming a progressive crushing chamber with the fixed liner. After entering, the material undergoes multiple compressions and grinding processes. The hydraulic system adjusts the main shaft position in real time to control the discharge particle size (accuracy ±1mm). When uncrushable foreign objects (such as metal blocks) enter, the hydraulic cylinder automatically releases pressure to protect the main unit.

(1) Multi-cylinder models use multiple sets of hydraulic cylinders distributed around the frame, offering stronger overload protection and discharge port adjustment capabilities. When crushing hard rock, their production capacity is more than 30% higher than that of single-cylinder models. However, their structure is relatively complex, resulting in higher manufacturing costs.
(2) Single-cylinder models have a simpler structure and are easier to maintain, making them suitable for crushing materials of medium to low hardness. If you mainly crush hard rocks such as granite and basalt, a multi-cylinder model is recommended; for processing medium to soft materials such as limestone, a single-cylinder model offers better value for money.
First, the processing capacity, feed particle size, and discharge particle size requirements need to be determined. The material hardness also needs to be considered; for hard rock crushing, a higher-power motor and more wear-resistant liners should be selected. It is recommended to provide detailed production line parameters so our engineers can provide you with a precise selection solution.
Processing capacity: 90-1200 tons per hour. Please provide parameters such as raw ore hardness and output particle size requirements; we can then provide a professional selection solution.
Yes, the multi-cylinder hydraulic cone crusher can be linked with equipment such as vibrating feeders, jaw crushers, vibrating screens, and belt conveyors through a PLC control system. By setting production process parameters, the entire production line can be automatically started and stopped, material flow rate adjusted, and finished product particle size closed-loop controlled.
It is recommended to install a pre-screening device at the feed inlet and select a cavity design with an extended non-parallel zone. Our cone crusher models are equipped with a self-cleaning hydraulic system, which can operate stably in feed with a moisture content below 8%, and provide a hot air drying interface when necessary.
The main operating costs include: electricity costs, consumption of wearing parts, lubricating oil and hydraulic oil, labor costs, and maintenance costs.
