Solve the problem from the material
The direct way to solve the problem of static electricity is to eliminate static electricity. Based on years of experience, Dayong Vibration will provide you with the following solutions:
Connect the ground wire to the screen of the vibrating screen (generally use a three-dimensional vibrating screen) to export the current;
Add antistatic agent to the material before feeding;
Increase the humidity in the workshop to increase the humidity of the material. Experiments show. When the air humidity is lower than 30%, it is conducive to friction to generate static electricity. If the humidity is increased to 45%, it will be difficult to generate static electricity.

The vibration motor runs with a lack of phase, the motor is noisy, and if it takes a long time to heat up, it will burn out due to heat. The voltage connected to the motor does not match the actual one.
The bearings of the vibration motor have not been maintained for a long time, and the grease or new bearings will be replaced. The heat will be generated during operation, and the motor will burn out during sweeping and boring.
The vibration motor is controlled by frequency conversion, and it runs at low frequency for a long time. Without strong cooling air, the motor is burned due to insufficient heat dissipation.
If it is a vibrating motor, the brake cannot be opened due to failure or is not fully opened, causing the motor to burn out.
The load is blocked or the motor is burnt due to overcurrent for a long time.
Vibration motor power supply voltage is too high. If the power supply voltage is too high, the motor winding coil will be burnt due to overcurrent.
Vibration motor insulation quality is poor. Such as turn-to-turn and phase-to-phase short circuit or breakdown with the shell.
The vibration motor is overloaded. If the power supply voltage of the missing phase is too low, mechanical failure, and power allocation margin is too small, they are all manifestations of overload. The most common causes of motor burnout are power supply phase loss and mechanical failure. Motor overload, motor short circuit, grounding, poor motor lubrication, etc. cause bearing damage and cause the motor to burn out;
The load is jammed or stuck, causing the motor to be overloaded and burned.
The insulation of the motor itself is aging, the motor is exposed to moisture or water, and the ventilation system of the vibrating motor is faulty

Dayong recommends using an ultrasonic vibrating screen. Because cobalt powder is a metal powder that is relatively difficult to sieve, cobalt powder has acid solubility, magnetism, and is relatively easy to agglomerate and has relatively strong adsorption, so the general rotary vibrating sieve sieves cobalt powder. On the basis of the rotary vibrating screen, an ultrasonic system is added. The ultrasonic system solves the phenomenon of material blocking, static electricity and agglomeration, and achieves the purpose of cobalt powder screening.

1. Use tools to adjust the angle of the vibration motor exciter to increase the excitation force, increase the jumping strength of the material and reduce the cohesiveness. The smaller the angle of the exciter, the greater the excitation force.
2. Thicken the vibration motor exciter, some original vibration motor exciters are lighter and it is difficult to make the screen have a greater bounce force.
3. Some materials can be rinsed with clean water, which can dilute the materials to reduce the cohesive force of the materials.
4. The screen life of wet materials is shorter than that of dry materials, and it is more troublesome to clean when the screen is severely blocked. Therefore, more screens should be prepared and replaced in time to avoid affecting production.
5. Increase manual cleaning. Every time the three-dimensional vibrating screen is working, it will be cleaned manually in time. Usually, the screen that has not been cleaned for more than two hours is easy to dry and sticks and is more difficult to clean. The second cleaning of materials is more difficult. It is recommended to equip high-pressure water grabbing for better production occasions.
6. Add a cleaning device to the screen surface of the three-dimensional vibrating screen, and the use of brushes is more common

1. The conveying material of the linear vibrating screen is not good
These problems of linear vibrating screen are generally caused by improper installation of the vibrating motor. Under normal circumstances, during the installation of the linear vibrating screen, the vibrating screen manufacturer will have professional technicians to follow to install and debug the screen. But in the process of using the sieve machine, some parts will become loose. Then the manufacturer needs to maintain the vibrating screen regularly. If you encounter a problem that is difficult to solve, you should contact the vibrating screen manufacturer in time, and do not disassemble the screen without permission to avoid unnecessary losses!
2. The direction of discharge of the linear vibrating screen may be caused by these reasons
1 Uneven phenomenon occurs when feeding.
2 The installation foundation plane and the center of gravity of the spring support are unstable and cause displacement.
3. The position of the exciter and whether the two sides of the swing eccentric block are balanced.
4. The stiffness of the damping spring is inconsistent and damaged.
5 The weight deviation of the screen body itself is a bit large, and the center of gravity is not accurately located.

The corresponding solution: 　　
　　 1. First, choose a reliable screen when choosing a vibrating screen; 　　
　　2. Check the tension of the screen frequently; check whether the screen is compacted.　　
　　3. If it is to screen liquid, add a hopper or a buffer when there is a strong impact force.　　
　　 4. If there is material accumulation, find out the cause as soon as possible, such as adjusting the eccentric block of the vibration motor
