In modern industrial production, circular motion vibrating screen has become an indispensable and important equipment with its unique performance and wide application. It is like a tireless craftsman, accurately screening all kinds of materials, providing a solid guarantee for the smooth production process.
The principle of circular motion vibrating screen
The working principle of circular motion vibrating screen is based on the theory of circular motion and vibration in physics. Driven by the motor, the screen box produces a specific frequency and amplitude of circular motion, so that the material is constantly tumbling and jumping on the screen surface. This kind of movement can effectively make the materials of different sizes and shapes separate quickly and realise accurate screening.
Its structure design is delicate and reasonable. The sturdy frame supports the whole screen box, which ensures that it remains stable under high-speed vibration. The screen mesh is the core component of the vibrating screen, which is made of high-quality material with the characteristics of wear-resistant, corrosion-resistant and high strength. Different specifications of the screen mesh can be replaced according to the actual needs to meet the screening requirements of various materials. The driving device provides strong power for the vibrating screen to ensure that it can run continuously and stably.
Advantages of Circular Motion Vibrating Screen
Circular motion vibrating screen has many significant advantages. Firstly, it has high efficiency screening capacity. Due to the use of circular motion, the movement of materials on the screen surface is more adequate, and the screening efficiency is greatly improved. Whether it is fine powder or large particles, it can be accurately separated in a short time. Secondly, it has good adaptability. It can be applied to a variety of materials with different properties, such as ores, coal, chemical raw materials, food and so on. Meanwhile, it can also be customised according to different production requirements to meet specific screening needs. In addition, the circular motion vibrating screen is simple to operate and easy to maintain. Low noise and energy consumption during the operation of the equipment meet the requirements of environmental protection.
Application of Circular Motion Vibrating Screen
In practical application, circular motion vibrating screen plays an important role. In the mining industry, it is used to screen and classify the ore and improve the grade and quality of the ore. In the coal industry, it can separate the impurities and gangue in coal to ensure the purity of coal. In the chemical industry, it is used for fine screening of chemical raw materials to ensure stable product quality. In the food industry, it can remove impurities and foreign matter in food to ensure the safety and hygiene of food.
With the continuous progress of science and technology, circular motion vibrating screen is also in constant innovation and development. The application of new materials and manufacturing process makes the performance of vibrating screen more superior and longer life. The introduction of intelligent technology makes the operation of the vibrating screen more convenient and the degree of automation is higher. For example, the state of the screen mesh and the flow of materials are monitored in real time by sensors, and the vibration frequency and amplitude are automatically adjusted to achieve the best screening effect.
Circular motion screen may encounter some problems in the process of use, the following are common problems and solutions:
一. Screen clogging
Problem performance:
The material is piled up on the screen mesh and can not pass through the screen holes normally, resulting in a decline in screening efficiency.
Solution:
1.Check the particle size distribution and humidity of the material. If the particle size of the material is not uniform or the humidity is too large, it is easy to cause clogging. The material can be pre-treated, such as crushing and drying, to improve the screening performance of the material.
2.Adjust the vibration parameters. Appropriately increase the amplitude and frequency of vibration, so that the beating of the material on the screen mesh is more violent, which helps to prevent clogging.
3.Clean the screen mesh regularly. Use special cleaning tools, such as brushes, high-pressure water guns, etc., to remove the clogging on the screen mesh in a timely manner.
二. Abnormal vibration
Problem performance:
The vibrating screen appears to vibrate violently, shake or make too much noise and other abnormalities during operation.
Solution:
1.Check whether the installation is firm. Make sure that the various parts of the vibrating screen are installed correctly and the ground bolts are tight and reliable. If the installation is not firm, it will cause the vibrating screen to shake during operation.
2.Check the motor and transmission. Problems such as motor failure, loose or worn belts may lead to abnormal vibration. Check the running status of the motor, adjust the tension of the belt, and replace the damaged parts if necessary.
3.Balance adjustment. If the centre of gravity of the vibrating screen is not balanced, it will also cause abnormal vibration. The centre of gravity of the vibrating screen can be balanced by adjusting the position of the counterweight block.
三. The output decreases
Problem performance:
The output of the screened material is obviously lower than expected.
Solution:
1.Check whether the screen mesh is damaged. Damaged screen mesh will cause some materials to pass through directly without screening, thus reducing the output. Replace the damaged screen mesh in time.
2.Analyse the material characteristics. If the fluidity of the material is poor, sticky or the density of accumulation is too high, it may affect the output. Corresponding measures can be taken, such as adding flow aids and reducing the humidity of the material.
3.Adjust the feeding speed. Too fast feeding speed will lead to the accumulation of materials on the screen surface, affecting the screening effect. Reasonable control of feeding speed to ensure that the material can be evenly distributed on the screen surface.
四. Parts wear
Problem performance:
The bearings, gears, springs and other parts of the vibrating screen are worn out, affecting the normal operation of the equipment.
Solution:
1.Regular inspection and maintenance. Regular inspection of the vibrating screen, timely discovery of worn parts and replacements. At the same time, lubricate and maintain the equipment to reduce the wear and tear of parts.
2.Select quality parts. When buying vibrating screen, choose reliable quality parts to improve the durability of the equipment.
3.Operate the equipment correctly. Avoid overloaded operation, frequent starting and stopping of the equipment to reduce the wear and tear of the parts.
In short, the common problems of circular motion screen should be analysed and dealt with in a timely manner to ensure the normal operation of the equipment and the screening effect. At the same time, regular maintenance of the equipment to extend the service life of the equipment.
Factors affecting the screening effect of circular motion vibrating screen:
一. The nature of the material
1.Particle size distribution
If the range of material particle size is wide, large particles may prevent small particles from passing through the screen holes, resulting in lower screening efficiency. According to the particle size distribution of the material, it is necessary to choose the appropriate aperture of the screen mesh.
For materials with very fine particles, they may adsorb or stick to each other on the screen mesh due to static electricity and other reasons, affecting screening. Measures such as adding anti-static agent can be taken to improve.
2.Humidity
High humidity materials are easy to bond into a ball, blocking the sieve holes, reducing the screening efficiency. Before screening, the material can be dried to reduce the humidity.
Humidity may also affect the fluidity of the material on the screen surface, when the humidity is too high, the fluidity of the material becomes poor, which is not conducive to screening.
3.Density
Different densities of materials on the screen surface of the movement state will be different. Denser materials may be easier to penetrate the screen under vibration, but may also cause more wear and tear on the screen.
The mixture of materials with large density difference may appear stratification phenomenon in the screening process, which affects the screening effect.
二. The parameters of the equipment
1.Vibration frequency and amplitude
Higher vibration frequency and amplitude can make the material jump more violently on the screen surface, increase the contact opportunity between the material and the screen, and improve the screening efficiency. But too high frequency and amplitude may also lead to material splash, equipment damage and other problems.
According to the material characteristics and screening requirements, the vibration frequency and amplitude should be reasonably adjusted. 2.
2.Screen aperture and shape
The aperture of the screen directly determines the size of the material that can pass through the screen. Too small aperture may lead to low screening efficiency, too large aperture can not achieve the required screening accuracy.
The shape of the screen will also affect the screening effect, such as square holes, round holes, long holes, etc. for different materials and screening requirements.
3.Equipment inclination angle
The inclination angle of the circular motion vibrating screen will affect the flow speed and residence time of the material on the screen surface. When the inclination angle is large, the material flow speed is fast, the residence time is short, and the screening efficiency may be reduced; when the inclination angle is small, the material flow speed is slow, and the residence time is long, which is conducive to improving the screening accuracy, but it may reduce the handling capacity.
三. The operating conditions
1.Feeding speed
Feeding speed is too fast will make the material pile up on the screen surface, affecting the screening effect; feeding speed is too slow may reduce the processing capacity of the equipment. The feeding speed should be reasonably controlled according to the screening capacity of the equipment and the characteristics of the materials.
2.Feeding mode
Uniform feeding can make the material on the screen surface distribution more uniform, improve screening efficiency. Adopt suitable feeding device, such as vibrating feeder, can achieve uniform feeding.
Avoid feeding materials directly impacting the screen, so as not to damage the screen and affect the screening effect.
3.Maintenance
Regular maintenance of the equipment, clean up the screen, check the wear and tear of parts and replace them in time to ensure the normal operation of the equipment and screening effect.
Keep the equipment clean to avoid material residue and impurity accumulation, also help to improve the screening effect.
In a word, circular motion vibrating screen occupies an important position in modern industrial production with its advantages of high efficiency, stability and adaptability. It is an indispensable and powerful assistant in industrial production, and has made great contributions to improving production efficiency and ensuring product quality. It is believed that in the future development, the circular motion vibrating screen will continue to play its advantages, constantly innovate and progress, and bring more surprises and value to industrial production.
