Professional introduction and detailed manufacturing process of Symons 7ft cone crusher:
Professional introduction:
The Symons 7ft cone crusher is a commonly used crushing equipment. It is suitable for crushing various materials such as ores and rocks of different hardness. It has the advantages of large crushing ratio, high production efficiency, and uniform product particle size. Its working principle is that through the swinging motion of the moving cone, the materials are crushed by the actions of compression, bending, and impact in the crushing cavity.
This crusher usually consists of parts such as a frame, a transmission shaft, an eccentric sleeve, a moving cone, a fixed cone, and a lubrication system. The eccentric sleeve drives the moving cone to perform a swinging motion around a fixed point. The moving cone sometimes approaches and sometimes moves away from the fixed cone, thereby realizing the crushing of materials.
Manufacturing process (general steps):
1. Design and planning: According to the performance requirements and technical specifications of the crusher, conduct detailed design and planning to determine the size, shape, and material of each component.
2. Material selection: Select high-strength and wear-resistant materials such as alloy steel to ensure the durability and stability of the crusher.
3. Casting or machining: Manufacture main components such as the frame, moving cone, and fixed cone. This may involve casting processes to obtain complex shapes; or through machining processes such as turning, milling, and grinding to achieve precise dimensional and surface quality requirements.
4. Eccentric sleeve manufacturing: The eccentric sleeve is a key component for realizing the movement of the moving cone and requires high-precision machining.
5. Transmission shaft production: Ensure that the transmission shaft has sufficient strength and precision to transmit power.
6. Installation of wear-resistant liners: Install wear-resistant liners on the surfaces of the moving cone and fixed cone to reduce wear and extend service life. The liners are usually made of special wear-resistant materials.
7. Assembly: Assemble each component, including installing the transmission shaft, eccentric sleeve, moving cone, fixed cone, etc., and ensure the fitting precision and smooth movement between them.
8. Installation of lubrication system: Set up an appropriate lubrication system, including oil pumps, oil pipes, filters, etc., to ensure good lubrication of each part of the crusher.
9. Quality inspection and debugging: Conduct comprehensive quality inspections on the assembled crusher, including tests on dimensional accuracy, movement performance, and crushing effect. Conduct necessary debugging and optimization to ensure that the crusher meets the design requirements and performance indicators.
10. Surface treatment: Perform surface treatments such as painting to prevent corrosion and improve appearance quality.
It should be noted that Symons 7ft cone crushers produced by different manufacturers may have certain differences in specific structure and manufacturing process. In addition, the actual manufacturing process needs to strictly follow relevant standards and specifications to ensure the quality and performance of the product. When using the crusher, it is also necessary to operate and maintain it reasonably according to the specific material characteristics and production requirements to give full play to its performance and extend its service life.
In addition, the cavity shape of the crusher also has an important influence on its performance. Taking the 7-foot Symons cone crusher as an example, when the new moving cone liner and fixed cone liner form a fine crushing cavity shape, the initial parallel belt length and the tight side width of the feed inlet have certain values. After a period of use, the length of the parallel belt will gradually become longer, the tight side width of the feed inlet will become narrower, and the processing capacity will decrease. For the medium crushing cavity shape, there is a similar change rule. As the service time increases, the length of the parallel belt gradually becomes longer, the feed inlet becomes smaller, and the processing capacity will also decrease. However, the thickness of the liner is far from being worn to the size that needs to be replaced. In practical applications, according to the change rule of the cavity shape and production needs, the operating parameters of the crusher should be adjusted reasonably.
