Vibrating screen discharge too slow analysis and solution reference
1. If this problem occurs when the newly purchased product is used for the first time, you should check whether the screen mesh of the rotary vibrating screen is at the same level as the outlet. If the screen mesh and the outlet are not level, it will cause the rotary vibrating screen to discharge The problem of slowness arises.

2. The second case is the adjustment of the motor angle. The angle of the eccentric block of the vibration motor of the rotary vibrating screen can be adjusted to change the trajectory of the material moving on the screen surface. The smaller the angle, the faster the material will spread out ;The larger the angle, the slower the material will spread out. Generally, the motor angle is adjusted to 35 degrees to 45 degrees. If the angle is above 45 degrees, there will be a problem of slow discharge, which is suitable for screening materials with less impurities.

The solution to the slow discharge of vibrating sieve

1. Increase the weight of the two heavy hammers

2. Change the included angle of the upper and lower weights
What we need to do if the ultrasonic vibrating screen transducer is overheated?
Ultrasonic vibrating screen is a screening equipment for fine materials, which can be widely used in the screening of food, medicine, chemical industry, metal powder and other materials. However, some users reported that the ultrasonic transducer overheated during use. So what factors are causing this problem? How to solve it?

1. There is material residue at the transducer interface

The transducer is installed on the screen frame. Due to long-term operation, the interface between the transducer and the screen frame will become loose, and excessive material falling to the interface of the transducer will cause poor heat dissipation of the transducer, thereby cause the transducer to heat up.
For this problem, we can check the transducer regularly, stop it immediately for maintenance if it is loose, and clean it up immediately if there is residue.

2. The short circuit of the connecting line causes the transmission signal to be abnormal

The ultrasonic screening system is composed of a transducer and an ultrasonic power supply, and the cable is connected to the two. If the cable is damaged, the transmission power will be abnormal and the temperature of the transducer will be abnormal. For this problem, we can check the connecting wire before and after production, and replace it immediately if any damage is found;
3. Ultrasonic power problem

For the parts that provide ultrasonic waves to the transducer, the output power will be unstable when the ultrasonic power supply fails. In the long run, the temperature of the transducer will be abnormal, which will affect the screening accuracy and output. When starting the ultrasonic power supply, please check the equipment in advance to ensure normal operation;

4. Voltage instability

Both the vibrating screen and the ultrasonic system require electricity to maintain operation, so if the power supply is unstable, it will also cause the transducer to overheat. Therefore, please check the connection cables regularly during production to ensure that the cables are normal and the power supply is stable.
Reasons for the clogging of the vibrating screen
When sieving with a vibrating screen, according to the nature of the material, various forms of sieve hole blockage will occur. The main reasons for the blockage of the sieve are as follows: (1) Contain a large number of particles close to the separation point of the sieve; (2) The material has a high water content; (3) Spherical particles or materials with multiple contact points to the sieve; (4) The material itself has strong static electricity; (5) Fibrous and dendritic materials; (6) There are many flake particles in the material; (7) The woven screen wire is thick.
How to prevent the vibrating screen from blocking the holes
Because most of the material particles that need to be screened are irregular, the cause of blockage is also diverse. In order to effectively prevent the screen of the vibrating screen from clogging, measures should be taken to address the reasons for the clogging of the above-mentioned screen holes. When the material particle size is finer, the mud content is more and the sieving particle size is smaller, the water will play a decisive role in the blockage of the screen. When the moisture in the material is greater than 5, if the material is dried unconditionally, the screen surface and sieve holes should be selected. Reasonable adjustment of the screen tension is an effective method to reduce the hole blocking of the screen. The reasonable tension causes the screen to produce a slight secondary vibration with the supporting beam, thereby effectively reducing the occurrence of hole blocking.
What are the advantages of ultrasonic vibrating screen?
Ultrasonic vibrating screen converts 220v, 50HZ or 110v, 60HZ electric energy into 38KHZ high-frequency electric energy, and turns it into 38KHZ mechanical vibration, so as to achieve the purpose of screening and net cleaning. The system superimposes a high-frequency and low-amplitude ultrasonic vibrator on the screen on the basis of the traditional vibrating screen. The ultra-fine powder receives huge ultrasonic acceleration, so that the material on the screen surface is always kept in a suspended state, thereby inhibiting adhesion and friction. , flat drop, and other blocking factors, the material is discharged from the corresponding outlet to complete the screening work, especially suitable for the screening of ultra-fine materials.
Advantages of ultrasonic vibrating screen:
High penetration rate and high screening efficiency;
It really solves the screening problems of strong adsorption, easy clumping, high static electricity, high fineness and other materials;
No cleaning devices such as bouncing balls are added to avoid secondary pollution of materials, and the screen has a long service life;
Self-cleaning function, the screen will not be blocked.
How to solve the screening problem of electrostatic materials
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.
