Cone crusher is one of the widely used mining machinery and equipment, with the development of the market, there are many types of products at home and abroad, and the performance of each type of crusher is not the same. At present, spring cone break and hydraulic cone break are more commonly used, and hydraulic cone break is divided into single cylinder hydraulic cone break and multi-cylinder hydraulic cone break. This article mainly compares the difference and advantages and disadvantages of single cylinder hydraulic cone break and multi-cylinder hydraulic cone break, hoping to bring some help to your selection.
Single cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher the structural differences of the main engine structure, components and wear parts, and the main differences are also reflected in the following aspects:
Discharge port adjustment mode is different
Single cylinder hydraulic cone broken
During normal operation, the main shaft cylinder is injected or discharged by the oil pump, so that the main shaft is moved up or down (the main shaft is floating up and down), and the size of the discharge port is adjusted. This adjustment may cause the discharge port to be more difficult to lock when breaking hard ore.
Multi-cylinder hydraulic cone broken
Through the hydraulic push hand or hydraulic motor, adjust the adjustment cap, so as to drive the adjustment ring in the support sleeve rotation (fixed cone spiral rotation up and down), to achieve the adjustment role. The advantage of this adjustment mode is that the discharge port is easy to lock.
Iron and cavity cleaning methods are different
Single cylinder hydraulic cone crusher
When the iron is over, the hydraulic oil is injected into the accumulator and the main shaft falls. After passing the iron, the accumulator will press the oil back and the crusher will run normally. Hydraulic pump is also used when cleaning the cavity.
Multi-cylinder hydraulic cone crusher
When the unbreakable foreign matter passes through the crushing chamber or the machine is overloaded for some reason, the hydraulic safety system realizes the insurance, the discharge port increases, and the foreign matter is discharged from the crushing chamber. If the foreign matter is stuck in the discharge port, the cavity cleaning system can be used to further enlarge the discharge port and discharge the foreign matter from the crushing chamber. Under the action of hydraulic system, the discharge port automatically resets, and the machine returns to normal work.

Lubrication system comparison
Single cylinder hydraulic cone crusher
Two oil inlet, one from the lower end of the spindle into the oil, lubricate spherical bearings, spherical tiles, frame bushing, main shaft bushing, and then lubricate large and small bevel gears;
The other way enters from the end of the drive shaft, lubricates the transmission shaft bushing, and the last two ways of oil discharge from the same oil outlet.
Multi-cylinder hydraulic cone crusher
After one oil hole enters the machine from the lower part of the machine, after reaching the middle of the spindle, it is divided into three branches: the inner and outer surface of the eccentric sleeve, the middle oil hole of the spindle reaches the ball bearing, and lubricates the large and small bevel gear through the hole;
The other one is fed by the hole on the drive shaft frame to lubricate the transmission bearing. The oil return is also through the oil return hole on the lower part of the bevel gear and the oil return hole on the dust cover.
Provides comparison of breaking force components
Single cylinder hydraulic cone crusher
The single cylinder hydraulic cone break is similar to the spring cone break, so the spindle and the moving cone are equivalent to the base support, and the eccentric sleeve drives the spindle to provide crushing force.
Multi-cylinder hydraulic cone crusher
The spindle of the multi-cylinder hydraulic cone is short, its diameter can be designed to be large, and it stands directly on the frame (rather than in the eccentric sleeve), providing a high bearing capacity, and the eccentric sleeve directly drives the dynamic cone to provide crushing force.
Different applicable materials
When crushing soft ore and weathered ore, the advantages of single cylinder hydraulic cone breakage are prominent, and when crushing medium hard and high hard ore, the performance of multi-cylinder hydraulic cone breakage is more outstanding.
For the fine crushing of medium hard ore and above, under the same specifications, the multi-cylinder cone can produce more qualified products, in general, the higher the hardness of the rock, the greater the difference between single cylinder and multi-cylinder operation effect.
Operation and maintenance
Single cylinder cone crusher simple structure and reliable performance: a hydraulic cylinder, simple and compact structure, low failure rate, low production cost (the simpler the mechanical system structure, the lower the failure rate, the higher the reliability, the more stable the operation).
Multi-cylinder cone broken top or side can be disassembled, quick and convenient maintenance: all parts can be disassembled and maintained from the top or side, moving cone and top cone disassembly is convenient, no need to disassemble the mounting frame, fastening bolts, making daily replacement more convenient.
Comparative analysis of advantages and disadvantages
Advantages and disadvantages of single cylinder hydraulic cone crusher
Advantage 1: The body structure of the single-cylinder hydraulic cone crusher is simpler than that of the multi-cylinder hydraulic cone, and the parts are fewer, and the design is more beautiful from the appearance.
Advantage 2: Due to the simple structure and low manufacturing cost, the price is also lower than that of multi-cylinder hydraulic cone crusher.
Advantage 3: In the actual operation process, the equipment installation and maintenance is convenient. And from the technical point of view, the single cylinder hydraulic cone has been technically improved on the sliding bearing, and the improved equipment can adapt to higher speed, increase the swing speed of the spindle, so that the size of the finished material is more in line with the requirements, and the output is higher.
Disadvantages: The biggest disadvantage of single cylinder hydraulic cone is that it has only one cylinder, so the crushing force is relatively small, if once broken some of the texture of the hard stone, it is recommended to choose multi-cylinder.
Advantages and disadvantages of multi-cylinder hydraulic cone crusher
Advantage 1: Multi-cylinder hydraulic cone crusher for the traditional spring cone crusher part of the performance upgrade, improvement, and reasonable structure. The equipment uses multi-cylinder hydraulic technology to make the crusher break relatively large, in the case of ensuring the output standard, the energy consumption is also controlled, and the applicable stone, especially suitable for crushing hardness of not more than 300Mpa stone.
Advantage 2: Multi-cylinder hydraulic has a special crushing chamber design, and the productivity is greatly improved. The semi-automatic hydraulic adjustment of the discharge port can effectively control the particle size of the stone, and the finished material can reach the size of its own needs. So it is more economical and practical to use.
Advantage 3: Good crusher manufacturers in the manufacture of multi-cylinder hydraulic cone break, will use high strength integral casting shell, and have iron protection, safe and reliable, no matter how hard the texture of the equipment broken stone, equipment performance is very stable, and long service life.
Disadvantages: The multi-cylinder hydraulic cone crusher uses the labyrinth sealing structure, which can play a dust-proof effect, but if it is a manufacturer with low experience or a manufacturer with poor manufacturing technology, the labyrinth sealing will also have dust entering, and if the stone with more dust is broken, it may cause difficulty in conditioning the discharge port. So be sure to choose a good brand reputation manufacturers.
