Cone Crusher
When the cone crusher is working, the motor drives the eccentric sleeve to rotate through the transmission device. The moving cone rotates and swings under the force of the eccentric sleeve. The section where the moving cone is close to the static cone becomes the crushing chamber. The material is crushed by multiple squeezing and impacts of the moving cone and the static cone. When the moving cone leaves this section, the material that has been crushed to the required particle size falls under its own gravity and is discharged from the bottom of the cone.

What is a cone crusher?
A cone crusher is a mechanical device that uses continuous extrusion, bending and shearing to perform secondary or tertiary crushing on medium-hard or above materials. It is an advanced hydraulic crusher with high power, large crushing ratio and high productivity.
The core feature of a cone crusher is that a crushing chamber is formed between the eccentrically rotating moving cone and the stationary fixed cone, and the material is crushed to the required particle size through the swinging motion of the moving cone. A cone crusher is a medium-fine crushing equipment, suitable for processing various ores and rocks with medium and high hardness, and is widely used in construction, chemical industry, water conservancy, railways, highways, building materials and other fields.
In recent years, cone crushers have gradually become popular among users due to their technological innovation, convenient operation, reliability and safety.
Single-cylinder cone crusher vs multi-cylinder cone crusher
There are two types of cone crushers commonly used at present: single-cylinder crusher and multi-cylinder crusher. So what is the difference between single-cylinder cone crusher and multi-cylinder cone crusher?
1. Different equipment structure
| Single-cylinder | Single-cylinder cone crusher is similar to spring cone crusher. The main shaft and moving cone are combined together and supported by bowl-shaped tiles. Therefore, the main shaft and moving cone are equivalent to the base support, and the eccentric sleeve drives the main shaft to provide crushing force. |
| Multi-cylinder | The main shaft of the multi-cylinder cone crusher is short and thick, and its diameter can be designed to be very large. It stands directly on the frame (not in the eccentric sleeve), and is directly supported by the frame. The bearing capacity provided is higher, and the eccentric sleeve directly drives the moving cone to provide crushing force. |
The difference in the mechanical structure of single-cylinder and multi-cylinder cone crushers determines that the frame forces of the two are also different when crushing materials. The frame of the former bears tensile stress, and the frame of the latter bears weakened tensile stress. Therefore, the multi-cylinder cone crusher can be better in terms of frame structure.
2. The discharge port adjustment method is different
| Single-cylinder cone crusher | When the single-cylinder hydraulic cone crusher is operating normally, when the main shaft cylinder is filled with oil or discharged through the oil pump, the main shaft is lifted or dropped, and the size of the discharge port is adjusted. |
| Multi-cylinder cone crusher | The multi-cylinder hydraulic cone crusher adjusts the adjustment cap through the hydraulic pusher or motor, thereby driving the adjustment ring to rotate in the support sleeve (the fixed cone spiral rotates and moves up and down) to achieve the adjustment effect. The advantage is that the discharge port is easy to lock. |
3. Different feeding methods
Generally speaking, both single-cylinder and multi-cylinder hydraulic cone crushers can be fully fed. The latter has no problem in achieving full feeding with its high bearing capacity, and can use the lamination principle.
The stone is crushed in the crushing chamber and squeezed against each other at the same time. The crushing also has a shaping effect, so the discharge particle shape is very good. But it should be noted that full feeding only means that the crushing chamber is filled with materials. At this time, while ensuring the crushing efficiency, it can also ensure uniform wear.
4. Different crushing effects
| Single-cylinder cone crusher | The single-cylinder hydraulic cone crusher has high crushing efficiency, flexible and directly adjustable discharge port, better medium crushing effect, and large passing capacity. |
| Multi-cylinder cone crusher | Multi-cylinder hydraulic cone crusher is a layered crushing machine. The faster the swing speed, the better the layered crushing effect. The swing speed of multi-cylinder hydraulic cone crusher is much faster than that of single-cylinder hydraulic cone crusher. Therefore, the fine particle level of the finished product of multi-cylinder hydraulic cone crusher is high and the product particle size is more uniform. |

Cone crusher parts
The cone crusher is mainly composed of the following systems:
1. Main frame
Cast steel structure, with reinforcement ribs at heavy load parts to withstand crushing reaction force.
2. Crushing cone
Moving cone (lower crushing wall): The surface is covered with high manganese steel lining, which rotates and swings with the eccentric sleeve.
Fixed cone (upper crushing wall/rolling mortar wall): Fixed to the adjustment sleeve, forming a crushing chamber with the moving cone.
3. Eccentric drive system
Motor → hydraulic coupling → small bevel gear → large bevel gear → eccentric sleeve, driving the moving cone to rotate and swing.
4. Hydraulic/spring system
Hydraulic type: multi-cylinder or single cylinder, to achieve discharge port adjustment, iron protection, and cavity cleaning.
Spring type: traditional overload protection, simple structure, easy maintenance.
5. Lubrication and cooling system
The thin oil station circulates lubrication of the main shaft and bearings; the temperature control switch prevents high temperature.
6. Adjustment and locking device
The hydraulic nut or screw adjusts the discharge port; the locking cylinder ensures the stability of the fixed cone during operation.
Performance advantages of cone crusher
A cone crusher utilizes the “laminated crushing” principle. Through continuous squeezing, bending, and shearing between an eccentrically rotating cone and a fixed fixed cone, it crushes medium-hard or harder materials into medium or fine crushing. It offers numerous advantages in material crushing.
1. Laminated crushing, uniform particle size.
The material is repeatedly squeezed within the crushing chamber, resulting in a high cubic content in the finished product and less than 10% flakes, significantly superior to traditional impact crushers.
2. High crushing ratio, high capacity.
The crushing ratio can reach 4–10, with a single unit throughput of 30–2,000 t/h (depending on the model). The unit energy consumption is 15–30% lower than that of a jaw crusher + impact crusher process.
3. Hydraulic protection and automation.
Features include over-metal release, hydraulic cavity clearing, and automatic discharge adjustment (with an error of ≤5 mm). Automatic cone retraction and reset in the event of uncrushable material reduces downtime.
4. Long life of wear-resistant parts
High manganese steel/composite liner + optimized crushing chamber curve extend life by 30–200% and reduce steel consumption per ton by 20%.
5. Easy maintenance
All components can be disassembled from the top or side, and liner replacement takes only 2–4 hours. Centralized lubrication with thin oil and labyrinth seals prevent oil-water mixing.
6. Diverse chamber types for wide adaptability
Four interchangeable chamber types: super coarse, medium coarse, fine, and ultrafine, enabling comprehensive coverage of “coarse to fine” crushing with the same main unit.
