Spring Cone Crusher

Spring cone crusher is a type of cone crusher that utilizes a spring mechanism to reduce material size by compressing it between moving pieces of steel, known as mantles or concaves, and a stationary piece called the bowl liner.


Spring cone crushers are capable of processing a wide range of materials, including:
 

1. Hard and Abrasive Materials: Spring cone crushers can effectively crush hard and abrasive materials such as granite, basalt, quartzite, and various types of ores.
2. Medium-Hard Materials: They are also suitable for processing medium-hard materials like limestone, dolomite, and sandstone.
3. Soft and Non-Abrasive Materials: While primarily designed for harder materials, spring cone crushers can also handle softer and less abrasive materials such as gypsum, coal, and clay.
4. Recycled Materials: Depending on the design and configuration, spring cone crushers may also be used to process recycled materials such as recycled concrete and asphalt.
5. Aggregates: Spring cone crushers are commonly used in the production of aggregates for construction and road building applications. They can crush various types of aggregate materials to produce uniform-sized particles for use in concrete, asphalt, and other construction projects.
6. Mining Ores: In mining operations, spring cone crushers are utilized to crush ores and minerals to extract valuable metals and minerals such as copper, gold, iron ore, and nickel.
7. Industrial Minerals: They can also process industrial minerals like talc, kaolin, and silica sand, among others.

 

Structure of Spring Cone Crusher

1. Frame: The frame of the spring cone crusher provides structural support and houses the other components of the crusher. It is usually constructed from heavy-duty steel or cast iron to withstand the forces generated during crushing operations.
2. Main Shaft: The main shaft is a long, vertical shaft that extends from the top to the bottom of the crusher. It rotates within the eccentric bushing, transmitting the crushing motion to the mantle.
3. Eccentric Sleeve / Bushing: The eccentric sleeve, also known as the eccentric bushing, is mounted on the main shaft. It rotates with the main shaft, causing the mantle to gyrate within the concave.
4. Mantle and Concave: The mantle is a stationary outer shell that is mounted on the main shaft and gyrates within the concave. The concave is a stationary inner surface that is shaped to create a crushing chamber. Material to be crushed is fed into the top of the crushing chamber and is crushed between the mantle and concave as the mantle gyrates.
5. Crushing Chamber: The crushing chamber is the space between the mantle and concave where the crushing action takes place. It is typically shaped to promote efficient crushing and maintain a uniform product size.
6. Spring System: The spring system consists of several springs arranged around the main shaft. These springs provide the force necessary to maintain a constant gap between the mantle and concave, allowing for adjustment of the crusher's setting.
7. Adjustment Mechanism: Spring cone crushers are equipped with mechanisms for adjusting the crusher's setting to control the size of the crushed material. This adjustment mechanism may be manual or hydraulic, depending on the specific design of the crusher.
8. Drive System: The drive system of a spring cone crusher typically consists of a motor and a belt or chain drive that transmit power from the motor to the main shaft, causing it to rotate.

 

Spring Cone Crusher Working Principle

Spring cone crushers are commonly used in secondary and tertiary crushing stages in aggregate production, mining operations, and recycling applications due to their reliable performance, high efficiency, and relatively low operating costs compared to other types of cone crushers.

1. Crushing Chamber: The material to be crushed enters the top of the cone crusher's crushing chamber, which is lined with concaves or mantles.
2. Crushing Action: As the mantle gyrates within the concave, the material is crushed between the mantle and the concave. The spring mechanism helps to maintain a consistent gap between the mantle and concave, ensuring uniform crushing.
3. Spring Mechanism: In a spring cone crusher, the spring system plays a crucial role in maintaining the gap between the mantle and concave. This allows for the adjustment of the crusher's setting to achieve the desired product size.
4. Discharge: Once the material reaches the desired size, it exits the crushing chamber through the bottom opening.

 

Advantages of Spring Cone Crusher

Spring cone crushers are widely used in various industries due to their unique advantages:
 

1. Reliable Operation: The spring mechanism ensures stable and consistent performance, providing reliable operation even under heavy loads.
2. Adjustable Setting: The spring system allows for easy adjustment of the crusher's setting to control the size of the crushed material. This flexibility makes spring cone crushers suitable for a wide range of applications.
3. High Efficiency: Spring cone crushers are known for their high efficiency in crushing operations. The combination of the spring mechanism and the crushing chamber design promotes efficient crushing of materials, resulting in higher productivity.
4. Cost-Effectiveness: Compared to other types of cone crushers, spring cone crushers often offer lower operating costs. The simplicity of their design and fewer moving parts contribute to reduced maintenance requirements and overall operational expenses.
5. Versatility: Spring cone crushers can be used in various crushing stages, including secondary and tertiary crushing, making them versatile for different applications in industries such as mining, quarrying, and construction.
6. Safety Features: Many spring cone crushers are equipped with safety features such as overload protection and hydraulic adjustment systems, which enhance operator safety and protect the crusher from damage.
