Ultrasonic vibrating screen introduces a low amplitude and high frequency ultrasonic vibration wave (mechanical wave) on the screen mesh based on the traditional vibrating screen to improve the screening performance of ultra-fine powder. It is especially suitable for users of fine powder with high added value.

1.Ignition of transducer vibrator: ceramic materials are broken, which can be checked with naked eyes and megger. Generally, as an emergency treatment measure, individual damaged vibrators can be disconnected without affecting the normal use of other vibrators.
2. Ultrasonic vibrator is affected with damp: the plug connected to the transducer can be checked with a megger, and the basic situation can be determined by checking the insulation resistance value. Generally, the insulation resistance is required to be greater than 5 megohms. If the insulation resistance value cannot be reached, the transducer is generally affected with moisture. You can put the transducer into the oven and set it at about 100 ℃ for drying for 3 hours or use a hair dryer to remove moisture until the resistance value is normal.
3. Degumming of the transducer: the transducer adopts the double assurance process of cementation and screw fastening, which generally occurs; Generally, if the transducer is used at full load for 10 years, there may be abnormal noise in the use and daily maintenance of the vibrating dewatering screen;
4. After use: Clean up after each use

Advantages of screening effect: the use of wooden grids does not affect the characteristics of the materials, and does not affect the quality of the materials during the screening process. Due to the characteristics of some materials, the use of iron grids will affect the characteristics of the materials, and the use of high-quality wood for wooden grids ensures that the characteristics of the materials remain unchanged and the product quality is guaranteed.
　　Cost advantage: The use of wooden grids for linear screens will greatly reduce manufacturing costs. Compared with the iron frame grid, the manufacturing cost can be reduced by 10%. As far as small and medium-sized users are concerned, the saving of procurement costs is the increase of gross production value;
　　Maintenance advantage: The wooden grid has a great advantage in follow-up maintenance. Due to the use of high-quality wood, users can rest assured in terms of durability, and subsequent maintenance and replacement are easier. Due to the previous advantage, you can consider storing several more sets of net racks, and you can directly replace the whole set of net racks when you need to replace them, which ensures the efficiency of production.

1. Insufficient tension of the screen causes the screen to vibrate greatly, which usually breaks or damages along the edge of the screen or the frame.
2. The quality of the screen is unqualified. Generally, the screen has an upper sieve layer (sub-network) and a lower load-bearing layer (parent network). The two layers are required to be tightly attached. If the tensioning process of the screen is poor , When the force layer at the bottom is tightened, the sieve layer is not tightened, and the throwing force of the material is greatly reduced during work, which affects the efficiency of the small fraction.
3. If the material stays on the screen for too long or too much time, the tension of the screen will be damaged, and the bag will eventually appear.

In the daily screening process, static electricity is generated due to the friction between the material and the screen, and static electricity makes the material clumps difficult to penetrate the screen, and it can also cause harm to the human body. So how to deal with the static electricity generated during the screening process? After many years of experience in the production of vibrating screens by our company, we believe that the following points are desirable to effectively handle static electricity in the screening process:

First, connect the ground wire (that is, the wire) on the screen to lead the current.
Second, add antistatic agent to the material before sieving.
Third, the materials go through a series of measures such as drying before screening.
Fourth, the materials are dried, high temperature and other measures before sieving.

The dust-free feeding station is a new type of feeding machine equipment, which is mainly used to manually open the bag to pour the material into the dust-free feeding station equipment, remove the dust through the filter element, and use the screw conveyor or the negative pressure dust collector to automatically suck and transport the feeding after the blanking. The dust particles generated in the process of unloading avoid the dust flying of traditional feeding methods. The dust-free feeding station is widely used in food, new energy lithium batteries, chemical industries and other industries.
The equipment can be applied to a variety of production processes. It can be used as a single powder feeding and unloading device, or it can be connected to various types of conveying equipment such as spirals and negative pressure vacuum feeders to realize dust-free conveying and feeding. It is environmentally friendly in the Xi Jinping era. The preferred feeding equipment in large environments.
Equipment advantages of dust-free feeding station:
1. The equipment has simple structure, convenient operation and low maintenance cost
2. Automatic control, safe and stable
3. Dust-free unloading, prevent dust from flying, safe and civilized production
4. It can be equipped with vibrating screen, iron remover, vacuum feeder and other equipment for integrated use.

In the production process of the linear vibrating screen, the material is concentrated on the screen surface and does not move. What is the cause? How to solve this problem?
Insufficient tension of the screen: When the linear screen is produced for a long time, the material will hit the screen during feeding, which will loosen the screen and cause the material to concentrate on the slack position of the screen. For this problem, the status of the screen can be monitored at all times during production. Once the screen is found to be loose or damaged, it should be shut down and replaced immediately;
Motor excitation force is asymmetry: The power source of the linear screen is provided by two horizontal vibration motors. When there is a problem with the motor, the material will not move. For this problem, check whether the motor phase angles are the same, whether the eccentricity of the eccentric blocks of the two motors are the same and whether the motor turns;
Damping spring problem: The four corners of the linear screen are supported by four damping springs. On the one hand, this device plays a supporting role, and on the other hand, it also plays a role in the tilt angle of the screen box. Once there is a problem with the spring, it will cause the material to run off or not to walk. For this problem, the spring can be checked regularly. Once the spring is found to be broken, please stop the machine for replacement and adjustment immediately.
The above is the problem and solution of the material staying on the screen surface during the production of the linear vibrating screen. Linear vibrating screen, as a screening equipment with simple structure and large output, can be widely used in food, medicine, chemical, metallurgy and other industries
