1、 The stoppage of the conveyor screw shaft rotation is generally caused by three reasons:　　1. The volume or weight of the conveyed material is too large, and the material cannot pass through the middle suspension bearing smoothly. The material resistance is too high at the middle bearing. Causing motor overload operation and shutdown. At this point, it is necessary to clean the materials in the conveyor.　　2. The resistance at the middle bearing is too high, and the seal is damaged. The material entering the bearing causes the bearing to not rotate or the bearing to be damaged.　　3. The bearing of the gearbox is burnt out.　　2、 The temperature of the gearbox bearings rises too quickly after driving, causing abnormal noise and accompanied by vibration of the motor and gearbox. At this point, the machine should be stopped quickly and the cause should be investigated in the following aspects:　　1. The bearing temperature at the output shaft of the reducer is normal, while the temperature at the input shaft is high. This is due to the loosening of the fixed components of the motor or the burning of the bearing at the output shaft of the reducer. It is necessary to loosen the coupling between the input shaft of the reducer and the motor and re calibrate and install it.　　2. The bearing temperature at the output shaft of the reducer is high. The temperature at the input shaft is normal. This is because the center of the spiral shaft has shifted or the bearing at the output shaft of the reducer has burned out, causing the first and last bearing seats to loosen. Need to loosen the coupling between the output shaft of the reducer and the screw shaft, and re calibrate and install it.　　3. The temperature at the output and input bearings of the gearbox is high. This is due to the loosening of the fixing bolts of the reducer or the burning of the bearings at both ends of the reducer. It is necessary to loosen the couplings at both ends of the reducer and re calibrate and install them.

　　The three-dimensional vibrating screen is suitable for relatively dry operating environments, as moisture or water ingress can easily cause the motor to burn out, especially when used again after several months of shutdown. So, how to implement waterproof and moisture-proof measures for the three-dimensional vibrating screen? Let me give you a brief introduction.　　1. Circulating hot air drying method:　　Make a drying chamber with insulation material (such as using refractory bricks), leaving an air outlet on top and an air inlet on the side. The air inlet is connected to the heating chamber, and a 220V electric furnace wire of about 3kW is insulated inside the heating chamber (other heating methods can also be used for the heating chamber). The heating chamber can be made of iron sheet, and a hair dryer can be used to blow hot air from the heating chamber into the drying chamber to dry the vibration motor winding. The temperature of the hot air in the drying room is controlled at around 100 ℃.　　2. Chemical desiccant water absorption method:　　Lime desiccant. The main component is calcium oxide, and its water absorption ability is achieved through chemical reactions, so water absorption is irreversible. Regardless of the humidity level in the external environment, it can maintain a moisture absorption capacity greater than 35% of its own weight, making it more suitable for low-temperature storage, with good drying and moisture absorption effects, and a lower price.　　In addition, a high-power incandescent bulb can be placed inside for drying, but be careful not to separate the bulb from the coil. The above is an introduction to some waterproof and moisture-proof methods for 3D vibrating screens. We hope it will be helpful to you.

　　One of the effective measures to protect the linear vibrating screen is the wear-resistant coating. The functions and methods of using wear-resistant coatings generally include two aspects:　　1、 Linear vibrating screens are generally easy to operate, require a large amount of work, and have high efficiency. The materials screened are usually large or hard, and long-term use may inevitably cause wear on the coating; If the degree of wear is high, the function of the coating will also fail, so wear failure is one of the main forms of failure for these wear-resistant coatings on vibrating screens. The wear failure mechanism varies for different types of coatings. But in terms of the main aspect, it is mainly due to deformation and wear caused by insufficient coating strength.　　To address this issue, we can introduce benzene rings or other rigid segments into the coating when using it; Increase the crosslinking degree and polar group content of polymers, fully utilize hydrogen bonds to enhance intermolecular forces, etc; It is also possible to increase rigidity by adding some corundum, quartz, or metal powder. Both methods have their own advantages, and we can choose to use them according to the actual needs of our customers.　　2、 The adhesion failure of the coating on the linear vibrating screen is another major reason for the failure of the wear-resistant coating.　　Ensuring that the coating does not peel off in practical applications is a key factor in the success or failure of coating applications.　　Some manufacturers use coating adhesion techniques that are unsuccessful, and the quality of the tree branches or adhesives used is poor, making them easy to peel off in water or cold conditions;　　Therefore, high-strength adhesives and improved resins should be used as much as possible to increase the content of polar groups and achieve better adhesion between the two in a straight line; The higher the viscosity of the improved coating, the stronger the coating on the linear vibrating screen, making it less likely to fall off easily. This is a great protective effect for the linear vibrating screen.

　　What should be done if the vibrating screen encounters dust during the screening process of materials? Usually, our approach is to add a dust cover, which can prevent dust leakage. But for some materials, it's not just about preventing leakage, but also about extracting dust. What should be done in this case?　　Raise the dust cover and open two holes to connect the dust removal device.　　Under what circumstances is dust removal modification necessary?　　The linear vibrating screen is mainly used to screen granular materials. During the operation of the vibrating motor, the material is subjected to this vibration force and constantly bounces on the screen surface. In this process, a large amount of dust is generated, and some dust will enter the lower screen frame through the sieve, affecting the quality of the product. Therefore, many manufacturers with high requirements for product quality choose to add dust removal devices to the vibrating screen. The customer who screens plastic particles has made adjustments to the dust cover on the vibrating screen and is waiting for the customer to install a dust removal device for use.　　What are the advantages of dust removal vibrating screen?　　The vibrating screen equipped with a dust removal device will be more accurate in screening materials, and it will also facilitate the cleaning of the vibrating screen in the future.

　　A feeder is an auxiliary equipment in the mechanized storage and transportation system of lime production enterprises. Its main function is to continuously and evenly feed processed or unprocessed materials from a certain equipment (hopper, storage bin, etc.) to the receiving equipment or transportation machinery. The vibrating feeder used in mines is used to uniformly or quantitatively supply materials from storage bins or other storage equipment to the receiving equipment, and is a device that implements automated flow operations.　　The feeder is a commonly used equipment in mining, and its simple structure, practicality, and convenience are the advantages of the vibrating feeder itself. Moreover, the vibrating feeder is continuous, uniform, and stable during use, so it occupies a very large proportion in mining equipment, and it can effectively control material flow.　　1. Everyone knows that the vibrating feeder is durable, but it must be placed in a stable location to prevent the machine from malfunctioning due to encountering foreign objects.　　2. In daily life, we need to regularly lubricate the vibrating feeder, which will reduce many unnecessary troubles during machine operation.　　3. When not in use, cover the machine with a rain cloth to prevent dust and rain.　　4. When working, special attention should be paid to the generator, which must not be too hot.

The equipment should be equipped with grounding wires and regularly inspected for grounding wires, power switches, cables, and other electrical components to ensure that they are in good working condition. If aging or wear occurs, they should be replaced in a timely manner.　　5. The main unit, motor, and fan of the airflow screening machine should be checked regularly, lubricating oil should be added regularly, and dust inside the motor should be cleaned. It should be ensured that they are thoroughly inspected once a year.　　6. The screen mesh of the airflow screening machine should be checked regularly, and any damage should be replaced in a timely manner to ensure even tension of the screen mesh.　　7. Pay attention to maintaining the condition of the electrical control box and try to avoid dust falling in, otherwise it may cause electrical components to malfunction or short circuit.　　8. It is recommended that customers establish a comprehensive daily maintenance plan for the airflow screening machine and adhere to it.

　　1. Noise source　　The noise mainly comes from the operation of gears and rolling bearings. The main source of gear noise is gear collision caused by manufacturing errors such as smooth contact. The noise radiated through the shell to the connected structure also promotes the total sound power to be increased at resonance frequency, especially for large diameter gears, whose noise pollution is more serious.　　The noise of rolling bearings is often caused by the impact of the rolling elements in the raceway and the impact and vibration of the retainer inside the bearing. Therefore, it is related to the stiffness and smoothness of the vibrator shaft.　　2. Diffusion　　Resonance diffusion. Due to resonance between the frequency of the noise source and the vibration noise caused by the excitation of the screen, crossbeam, pipe, etc. In addition, resonance occurs when the natural frequency of the component is a multiple of the operating frequency of the sieve. It can be said that there must be resonance phenomenon in the center where strong noise is generated by the mechanical vibrating screen. Related to area. The diffusion noise is proportional to the area. From the characteristics of acoustics, it is difficult for low-frequency sounds to form noise without large-scale vibrations. Therefore, many inherent vibrations of large-scale vibrations are fundamentally in the low-frequency region. From this, it can be seen that there is a relative relationship between the area of the vibrating body and the generation of noise. The sieve, as a vibrating body, generates low-frequency noise due to the large-scale vibration of components such as the sieve plate and frame.　　3. Connect　　Poor connection (looseness) can cause impact, such as the screen frame and screen mesh colliding and the screen body components becoming loose. Due to rigid connections, there is significant noise.

　　Swing screen, also known as swing vibrating screen, is a screening equipment that imitates manual screening actions. This series of equipment has good screening effect on cylindrical, elongated, and irregularly shaped materials without damaging the characteristics and shape of the materials themselves, meeting the requirements of modern people for screening materials: high efficiency and high precision. At present, swing screens are widely used in industries such as chemistry, food, medicine, and fertilizers.　　Do not stack any other debris around the swing screen machine, and the surrounding environment should also be kept clean. The price of the MSG swing screen should not be contaminated with other dust as much as possible to avoid the influence of other debris and prevent inaccurate screening of grains after screening. Before starting up and using the swing screen, it is necessary to check whether there are any debris in the machine compartment. The price of the glass bead swing screen should be cleaned to prevent different debris from mixing together and affecting the accurate screening of grains.　　Swing screens can be cleaned using bouncing balls, which is simple to use and easy to maintain. It is suitable for most granular materials, and ultrasonic cleaning is also a widely used cleaning method. It not only cleans the screen mesh, but also significantly improves production capacity. Suitable for most fine, high-yield, and difficult to screen materials, it improves work efficiency and time.　　Overall, China's swing vibration equipment is constantly improving and upgrading, and the market is showing a thriving trend. In the context of the continuous expansion of the food and drug market, domestic vibrating screen equipment should strengthen innovative technology, integrate market requirements, seize industry trends, and continuously meet the needs of more industries.
