Symons 7FT Cone Crusher Parts: An In - Depth Look
Introduction
In the realm of mining and aggregate processing, the Symons 7FT cone crusher stands as a workhorse. Its ability to efficiently break down large rocks into smaller, more manageable sizes is crucial for various industries. At the heart of this machine's functionality are its parts, each playing a distinct and vital role. Understanding these parts is essential for operators, maintenance crews, and those in the market for replacement components. This article delves deep into the Symons 7FT cone crusher parts, exploring their functions, common types, and the importance of proper selection and maintenance.
Key Components of the Symons 7FT Cone Crusher
1. Eccentric Bushing Assembly
The eccentric bushing assembly is a fundamental part of the Symons 7FT cone crusher. It consists of an outer eccentric bushing (such as part number 2214 - 7561) and an inner eccentric bushing (e.g., 2214 - 6721). The outer eccentric bushing, weighing around 485 units (the unit could be kilograms depending on the context), is designed to house and support the inner eccentric bushing. The inner eccentric bushing, with a weight of approximately 335 units, plays a key role in generating the eccentric motion that is characteristic of cone crushers.
This eccentric motion is what causes the cone crusher's mantle to gyrate within the bowl liner. As the eccentric bushing rotates, it imparts a circular - like motion to the mantle, creating a variable gap between the mantle and the bowl liner. This variable gap is essential for the crushing process as it allows the material to be squeezed and broken down in a continuous and efficient manner. The proper functioning of the eccentric bushing assembly is crucial for maintaining the correct gyrating motion of the mantle. If there is excessive wear or misalignment in the eccentric bushings, it can lead to uneven crushing, reduced efficiency, and potential damage to other parts of the crusher.
2. Bowl Liner
The bowl liner is one of the most critical wear parts in the Symons 7FT cone crusher. There are several different bowl liner part numbers, such as 4830 - 8556, 4830 - 9100, 4830 - 9472, and 4830 - 9741, among others. Bowl liners can vary significantly in weight, with some weighing as much as 3818 units (e.g., 4830 - 9100 hd bowl liner).
The bowl liner forms the stationary outer surface of the crushing chamber. As the mantle gyrates within the bowl liner, the material being crushed is forced against the bowl liner's surface. The bowl liner is designed to withstand the high - impact forces generated during the crushing process. It is typically made of high - manganese steel or other wear - resistant alloys. High - manganese steel is preferred due to its ability to work - harden under the impact of the crushing material. As the surface of the bowl liner is continuously bombarded by rocks, the steel hardens, increasing its wear resistance.
Over time, due to the abrasive nature of the crushing process, the bowl liner will wear down. When the wear reaches a certain level, the performance of the crusher will be affected. The crushing efficiency may decrease, and the quality of the crushed product may deteriorate. Regular inspection of the bowl liner's wear condition is essential, and timely replacement is necessary to ensure optimal crusher performance.
3. Mantle
The mantle is another crucial wear part in the Symons 7FT cone crusher. Part numbers like 5013 - 8101 (upper mantle), 5013 - 8201 (upper mantle), 5013 - 8601 (lower mantle), and 5013 - 8801 (mantle) represent different variations of the mantle. The mantle is attached to the main shaft and rotates eccentrically within the bowl liner.
It works in tandem with the bowl liner to crush the material. As the mantle moves closer to the bowl liner, the material between them is subjected to intense pressure, causing it to break. The design of the mantle's surface is carefully engineered to ensure efficient crushing. Some mantles may have a specific profile or texture to enhance the crushing action. Similar to the bowl liner, the mantle is made of wear - resistant materials, often high - manganese steel.
The wear pattern on the mantle is different from that of the bowl liner. The areas of the mantle that are in closer proximity to the bowl liner during the gyrating motion tend to wear more quickly. Monitoring the wear of the mantle is important as an unevenly worn mantle can lead to inefficient crushing and increased stress on other parts of the crusher.
4. Main Shaft
The main shaft (e.g., part numbers 6886 - 7804, 6886 - 7662, 6886 - 7943) is a major structural component of the Symons 7FT cone crusher. It can be quite heavy, with some versions weighing around 2815 units or even more (such as 6886 - 7943 main shaft with a weight of 3082 units).
The main shaft provides the support and rotational drive for the mantle. It is connected to the eccentric bushing assembly and rotates along with it. The main shaft must be made of high - strength steel to withstand the significant forces and torque generated during the crusher's operation. Any defect or excessive wear in the main shaft can lead to catastrophic failure of the crusher. Regular inspection of the main shaft for signs of cracks, wear, or misalignment is essential.
In addition to providing mechanical support, the main shaft also plays a role in transmitting power from the drive system to the mantle. A well - maintained main shaft ensures smooth and efficient operation of the crusher, while a damaged or worn - out main shaft can cause vibrations, reduced performance, and potential downtime.
5. Countershaft and Associated Parts
The countershaft assembly is an important part of the Symons 7FT cone crusher's drive train. The countershaft (e.g., part number 6876 - 1324) is supported by countershaft box bushings (such as 2206 - 8500) and rotates along with the pinion (e.g., 3682 - 7652).
The countershaft is responsible for transmitting power from the motor to the main shaft through a series of gears. The pinion, which is mounted on the countershaft, meshes with the large gear on the eccentric bushing assembly. As the motor rotates the countershaft, the pinion drives the large gear, causing the eccentric bushing assembly to rotate.
The countershaft box bushings are designed to reduce friction and wear between the countershaft and its housing. They are typically made of bronze or other low - friction materials. Proper lubrication of these bushings is crucial for their longevity and the smooth operation of the countershaft. If the bushings wear out, it can lead to increased friction, overheating, and potential damage to the countershaft and other associated parts.
6. Feed - Related Parts
  • Feed Cone: The feed cone (e.g., part numbers 2618 - 7681, 2618 - 8161) is responsible for guiding the material into the crushing chamber. It has a specific shape that helps to distribute the incoming material evenly around the mantle. The feed cone is designed to handle the flow of large rocks and direct them towards the crushing zone. If the feed cone is damaged or worn, it can cause uneven feeding of the material, leading to inefficient crushing and potential blockages in the crushing chamber.
  • Feed Plate: There are different types of feed plates, such as the 5598 - 7941 feed plate - 6 bolt and 5598 - 8154 feed plate - 4 bolt. The feed plate is located at the entrance of the crushing chamber and helps to control the rate and direction of the material entering the crusher. It also protects the crusher's housing from direct impact by the incoming rocks. A well - designed feed plate can improve the overall efficiency of the crusher by ensuring a consistent and proper flow of material.
Importance of Quality Parts and Maintenance
1. Performance Optimization
Using high - quality Symons 7FT cone crusher parts is essential for achieving optimal performance. When all parts are in good condition and properly matched, the crusher can operate at its designed capacity. For example, a well - worn bowl liner and mantle that are still of high quality will provide a consistent and efficient crushing action, resulting in a higher output of properly sized aggregate. In contrast, using sub - standard or worn - out parts can lead to reduced crushing efficiency, lower throughput, and a higher percentage of over - sized or undersized product.
2. Extended Equipment Lifespan
Regular maintenance and the use of quality replacement parts can significantly extend the lifespan of the Symons 7FT cone crusher. By promptly replacing worn - out parts such as bushings, liners, and bearings, operators can prevent further damage to other components. For instance, if a worn - out countershaft box bushing is not replaced, it can cause excessive wear on the countershaft and eventually lead to failure of the entire drive train. Proper maintenance also includes regular lubrication of moving parts, which reduces friction and wear, thereby increasing the overall lifespan of the crusher.
3. Safety Considerations
Faulty or worn - out parts can pose a significant safety risk in a cone crusher operation. For example, a cracked main shaft could potentially break during operation, causing the mantle to dislodge and create a dangerous situation for operators and nearby workers. By ensuring that all parts are in good condition and regularly inspected, the risk of such safety - critical failures can be minimized.

The Significance and Function of Main Shaft 68867663 / 6886 - 7663 in Symons 7FT Cone Crusher
Introduction
In the intricate world of Symons 7FT cone crushers, the Main Shaft 68867663 / 6886 - 7663 stands as a linchpin, playing a multifaceted and indispensable role. This shaft is not just a simple component; it is the backbone that enables the crusher to function efficiently and effectively in the demanding environments of mining and aggregate processing. Understanding its significance, construction, and maintenance requirements is crucial for ensuring the long - term performance and reliability of the Symons 7FT cone crusher.
Physical Characteristics and Construction
The Main Shaft 68867663 / 6886 - 7663 is a substantial component, typically fabricated from high - strength steel alloys. The choice of material is not arbitrary; it is a result of careful engineering considerations. High - strength steels are selected for their ability to withstand the extreme forces and torques that the main shaft experiences during the crusher's operation. These forces can include the massive impact of large rocks being crushed, the continuous rotational stress, and the vibrations generated by the machine.
The shaft often has a precisely machined surface. The smoothness of the surface is not merely for aesthetic purposes but is essential for reducing friction and wear. When the shaft rotates at high speeds within its bearings, a rough surface could cause increased friction, leading to overheating, premature wear of the shaft and bearings, and ultimately, a reduction in the efficiency of the crusher. The diameter and length of the Main Shaft 68867663 / 6886 - 7663 are designed to match the specific requirements of the Symons 7FT cone crusher. A shaft that is too thin may not be able to withstand the forces, while a shaft that is too thick could add unnecessary weight and inertia, affecting the overall performance of the machine.
Function in the Symons 7FT Cone Crusher
Power Transmission
At its core, the Main Shaft 68867663 / 6886 - 7663 is responsible for power transmission. It serves as the link between the drive system of the cone crusher, which could be an electric motor or a diesel engine, and the crushing mechanism. As the drive system rotates, it imparts torque to the main shaft. The shaft then transfers this rotational energy to the mantle, which is an integral part of the crushing chamber. The mantle, attached to the main shaft, gyrates within the bowl liner, creating the necessary motion to crush the incoming material. Without a properly functioning main shaft, the power generated by the drive system would not be effectively transferred to the crushing components, rendering the crusher inoperable.
Support for the Mantle
The main shaft also provides crucial support for the mantle. The mantle is a key wear part of the cone crusher that directly interacts with the material being crushed. It is constantly subjected to high - impact forces as rocks are squeezed and broken between the mantle and the bowl liner. The Main Shaft 68867663 / 6886 - 7663 holds the mantle in place and ensures that it maintains the correct alignment within the crushing chamber. Any misalignment of the mantle, which could be caused by a damaged or worn - out main shaft, can lead to uneven crushing. Uneven crushing not only reduces the quality of the final product but also places additional stress on other parts of the crusher, such as the bowl liner and the eccentric bushing assembly.
Contribution to the Eccentric Motion
In a Symons 7FT cone crusher, the eccentric motion of the mantle is what enables the efficient crushing of materials. The Main Shaft 68867663 / 6886 - 7663, in combination with the eccentric bushing assembly, is responsible for generating this eccentric motion. As the main shaft rotates, the eccentric bushing, which is mounted around the main shaft, causes the mantle to move in an elliptical or circular - like path within the bowl liner. This variable - gap motion between the mantle and the bowl liner allows the material to be gradually crushed as it moves through the crushing chamber. The accuracy and consistency of this eccentric motion are highly dependent on the integrity of the main shaft. A bent or damaged main shaft can disrupt the eccentric motion, leading to inefficient crushing and potential damage to other components.
Maintenance and Inspection
Regular Visual Inspections
To ensure the continued proper functioning of the Main Shaft 68867663 / 6886 - 7663, regular visual inspections are essential. Maintenance crews should look for signs of wear, such as scratches, grooves, or pitting on the surface of the shaft. These marks could indicate that the shaft is experiencing excessive friction or that foreign objects have entered the crusher and come into contact with the shaft. Cracks are another critical issue to watch for. Even a small crack in the main shaft can quickly propagate under the high - stress conditions of the crusher, leading to catastrophic failure. Visual inspections should also include checking the alignment of the shaft. If the shaft appears to be misaligned within its bearings, it could be a sign of bearing wear or damage, which can also affect the performance of the main shaft.
Lubrication
Proper lubrication is a cornerstone of maintaining the Main Shaft 68867663 / 6886 - 7663. The shaft rotates within bearings, and without adequate lubrication, the friction between the shaft and the bearings would increase significantly. This would not only lead to increased wear of the shaft and bearings but also cause overheating. High temperatures can weaken the material of the shaft and bearings, reducing their lifespan. Lubricants used for the main shaft should be of high quality and suitable for the operating conditions of the cone crusher. They should be able to withstand the high loads, temperatures, and contaminants that are present in the crusher environment. Regular lubrication intervals should be established based on the manufacturer's recommendations and the actual operating conditions of the machine.
Vibration Analysis
Vibration analysis is a valuable tool for monitoring the health of the Main Shaft 68867663 / 6886 - 7663. When the main shaft is operating properly, it should produce a consistent and relatively low - level vibration. However, if there are issues such as misalignment, bearing wear, or internal damage to the shaft, the vibration pattern will change. By using vibration sensors to measure the vibration levels and frequencies of the main shaft, maintenance personnel can detect potential problems early. For example, an increase in vibration frequency could indicate bearing wear, while an irregular vibration pattern might suggest a crack or misalignment in the main shaft. Early detection through vibration analysis allows for timely maintenance or replacement of the main shaft, preventing unexpected breakdowns and costly production losses.
Importance in Overall Crusher Performance
Efficiency
The Main Shaft 68867663 / 6886 - 7663 has a direct impact on the efficiency of the Symons 7FT cone crusher. A well - maintained and properly functioning main shaft ensures smooth power transmission and consistent eccentric motion. This results in efficient crushing, with a higher throughput of properly sized aggregate. In contrast, a faulty main shaft can cause energy losses in the form of increased friction, vibration, and misalignment. These energy losses not only reduce the efficiency of the crusher but also increase its energy consumption. For a large - scale mining or aggregate processing operation, even a small decrease in crusher efficiency can translate into significant financial losses over time due to increased energy costs and reduced production output.
Product Quality
The quality of the crushed product is also closely tied to the performance of the Main Shaft 68867663 / 6886 - 7663. An evenly worn and correctly aligned main shaft allows the mantle to move in a consistent manner within the bowl liner. This consistency in motion ensures that the material is crushed evenly, resulting in a more uniform product size distribution. If the main shaft is damaged or misaligned, the mantle may not move properly, leading to uneven crushing. This can result in an increased percentage of over - sized or undersized particles in the final product, which may not meet the required specifications for various applications such as construction materials.
Equipment Longevity
The Main Shaft 68867663 / 6886 - 7663 plays a crucial role in determining the overall longevity of the Symons 7FT cone crusher. By providing reliable power transmission and support for the mantle, a healthy main shaft helps to distribute the forces evenly throughout the crusher. This reduces the stress on other components, such as the bowl liner, eccentric bushing, and bearings. On the other hand, a failing main shaft can cause a domino effect of component failures. For example, if the main shaft misaligns, it can put excessive stress on the bearings, causing them to wear out prematurely. This, in turn, can lead to further misalignment and damage to other parts of the crusher. By investing in proper maintenance and timely replacement of the Main Shaft 68867663 / 6886 - 7663 when necessary, operators can significantly extend the lifespan of the entire cone crusher.
Conclusion
The Main Shaft 68867663 / 6886 - 7663 is a vital and complex component within the Symons 7FT cone crusher. Its physical characteristics, functions in power transmission, support for the mantle, and contribution to the eccentric motion are all critical to the crusher's operation. Regular maintenance, including visual inspections, proper lubrication, and vibration analysis, is essential for ensuring its continued performance. The main shaft's impact on crusher efficiency, product quality, and equipment longevity cannot be overstated. In the competitive and demanding industries of mining and aggregate processing, a well - maintained Main Shaft 68867663 / 6886 - 7663 is not just a component but a key to the success and profitability of the entire operation.
