Q: How to choose the appropriate screening equipment for oneself correctly？
A: 1、 Determine the number and characteristics of materials: Ultrasonic vibrating screen is mainly designed for high-precision powder materials or materials that are prone to clogging. If the material mesh size is above 300 or there are screening difficulties such as easy blockage, adsorption, sticking, static electricity, and specific gravity, ultrasonic vibrating screens can be considered. For easily sieved materials with a mesh size of 300 or less, a three-dimensional rotary vibrating screen or a linear vibrating screen can be selected; 2、 Screen volume: The diameter of the sieve surface is the main criterion related to the yield. We should clearly define our own production volume, production time, and reasonable selection of production space when making choices; 3、 Material: The material of ultrasonic vibrating screen can be divided into two types: one is 304 stainless steel material in contact with the material, and the other is 304 stainless steel material for the entire machine. 4、 Screen machine accessories: The main accessories of ultrasonic vibrating screen include: ultrasonic power supply, ultrasonic transducer, and vibration motor. The vibration motor is the power source for the operation of the vibrating screen, and the quality of the motor directly affects the service life and output of the ultrasonic vibrating screen.
Q: What are the advantages of ultrasonic sieving system?
A: Mainly due to the following advantages: 1. The ultrasonic vibrating screen screening equipment adopts PID control algorithm, which is fast and accurate, ensuring that it always operates at frequency and current, greatly improving production capacity; 2. Decompose adhesive substances, reduce the amount of material on the screen, and increase the screening rate of ordinary vibrating screens by 5-20 times; 3. Accelerate the separation of agglomerates, high precision, high density, high classicality, light density, and adsorbed materials, and accelerate the screening processing capacity; 4. A unique screening system that does not require the addition of any other screen cleaning devices, and has self-cleaning functions and non clogging mesh holes; 5. The screening particle size is increased by 1% -100%, and the yield is increased by 1-15 times, meeting the screening treatment of fine particles with a mesh size of 400 or more; 6. It can clearly separate small particles with similar diameters; 7. Not changing the characteristics of screened materials, especially suitable for new materials; 8. Prevent blockage of 50-625 mesh holes and similar particles from causing blockage to the mesh holes, and extend their service life; 9. The performance of the ultrasonic vibrating screen system will not increase the operating temperature and will continue to work. It can control the temperature rise for drug, thermosetting coatings, and raw material operations; 10. Suitable for separating powders through screens ranging from 20 microns to 300 microns, it has a good screening effect on some difficult to screen materials.
Q: What screening equipment is good for screening cassava starch?
A: Ultrasonic vibrating screen is a derivative of rotary vibrating screen, which adds ultrasonic and frequency conversion devices on the basis of the original vibrating screen vibration, effectively solving the problem of mesh blockage in screening. It is a very useful fine screening machine. Improve the flattening (light contact between powder and mesh) and slip effect of low-density powder in gravity settling, improve the retention or wedging of high-density metal at the mesh, and improve the adhesion effect of electrostatic powder, thereby improving screening efficiency and quality.
Q: Which equipment is suitable for screening 300 mesh silicon micro powder?
A: Silicon micro powder screening, fine powder is the finished product, and the coarse material on the screen is generally 20-30%, not too little, so only a rotary vibrating screen can be used. In addition, if the powder is too fine, the material is difficult to screen, and ultrasonic waves need to be added.
Q: What is the reason for the small amplitude of ultrasonic sieving system? How to solve it?
A: The reason for the small amplitude of ultrasonic vibrating screen is due to: screen mesh, cable connection of ultrasonic screening system, resonance, and ultrasonic transducer. 1. The screen is not tightened or the screen is not glued during installation, resulting in a decrease in amplitude; 2. Ultrasonic screening system cable: The ultrasonic screening system is an important screening system of the equipment, and the cable connects the ultrasonic power supply and transducer. If the insulation work of the cable is not done well, it will also lead to a decrease in amplitude; 3. Resonance: Cracks or damage to the screen frame or vibration motor, resulting in frequency imbalance and reduced amplitude; 4. Ultrasonic transducer: If the grid is not locked tightly with the transducer, it can also cause a decrease in amplitude. Solution: 1. If there is a problem with the screen, check by hand whether the screen is open or tight. If it is found to be open or not tight, remove the screen and tighten it again; 2. If there is a problem with connecting cables, carefully check the insulation value of the cables and plugs. If any problems are found, they should be resolved in a timely manner; 3. Ultrasonic transducer, check the contact area between the grid and the transducer, and clean any foreign objects found; 4. Resonance issue, check the screen frame or motor. If cracks are found, immediately stop the machine and contact our relevant technical personnel for maintenance and testing.
Q: How to clean the ultrasonic sieving system?
A: 1. When cleaning ultrasonic vibrating screens, the temperature should be between 30 ℃ and 50 ℃. If it is lower or higher than this temperature, the cleaning effect cannot reach the best; 2. Cleaning ultrasonic vibrating screens requires the use of cleaning solution. The higher the viscosity and gas content of the cleaning solution, the better the cleaning effect; 3. The sound intensity of ultrasonic vibrating screen during cleaning should be between 1w and 2w/mm ² Left and right, because sound intensity is also an important factor affecting the cleaning effect of equipment; 4. When cleaning the ultrasonic vibrating screen, attention should also be paid to the location of the cleaned object and the depth of the cleaning solution. When the location of the cleaning object is relatively hidden, the depth of the cleaning solution should be adjusted appropriately to ensure that the target position can be cleaned. The cleaning work of the ultrasonic vibrating screen should be a key maintenance focus, and a plan should be formulated and strictly implemented, because the ultrasonic vibrating screen mainly screens high-quality and fine powders. Therefore, a clean operating environment can effectively improve the screening effect and accuracy, and also extend the service life of the screening machine.
Q: How to clean and maintain ultrasonic vibrating screens？
A: Ultrasonic vibrating screen can screen and process fine powders and some high-precision materials. When using it, attention should be paid to protecting the transducer. Please note the following points: 1. To avoid power overcurrent or damage to the grid and transducers, please do not turn on the power when the grid is not stretched; 2. During operation, avoid dust from entering the ultrasonic transducer; 3. Maintain stable power supply voltage; 4. To ensure that the ultrasonic transducer is not damaged, the ultrasonic vibrating screen must operate at the rated current;
Q: What is the difference between ultrasonic vibrating screen and ordinary vibrating screen?
A: 1. Different yields Why is it said that the production is different? This is because due to the installation of an ultrasonic screening internal system, the output of ultrasonic vibrating screens for screening particle capacity and powder materials is 2-10 times that of ordinary vibrating screens; 2. Materials with special properties For example, materials with special properties such as mesh adhesion, adsorption, static electricity, easy agglomeration, and light density. However, ordinary vibrating screens can effectively screen materials with low mesh sizes. Therefore, when selecting screening equipment, please choose the appropriate ultrasonic sieving system according to your own production requirements; 3. Resolve network congestion issues Compared to ordinary vibrating screens, its cleaning device is a bouncing ball, and granular materials can also be cleared. For some precision powder materials and materials with special properties, the cleaning effect is not obvious. However, the existence of ultrasonic vibrating screens can effectively clean multiple screen surfaces to achieve the goal of not blocking the screen; 4. Different screening accuracy Because it is equipped with a dedicated ultrasonic system, the screen surface undergoes three-dimensional motion while also having a high-frequency and low amplitude ultrasonic sieving system, which suspends the material at low altitude on the screen surface and increases the screening accuracy. The screening accuracy reaches over 95%, while compared to ordinary vibrating screens, its screening accuracy can only reach about 60% -70%.
