Precautions for three-dimensional vibrating screen

1.Uniform feeding: the feeding amount should meet the equipment processing. Too much material feeding at one time will hinder the normal movement of the material on the screen surface, which will not only easily make the screen mesh fatigued and loosen, but also greatly reduce the material handling capacity. Giving a large amount of material at one time will suddenly increase the load of the vibration motor that is running unbalanced, causing damage to the motor and reducing the life of the motor.

2.The feeding method with strong impact force must be equipped with a buffer hopper. The material directly impacts the mesh surface, which not only consumes the exciting force generated by the vibration source, but also easily causes damage to the mesh surface and screen fatigue, which affects the output and screening and filtration. quality.

3.If the screening material is corrosive, please clean it up in time after use.

4.Please watch the working net frequently to see if it becomes loose, please tighten the net again.

5.If the screen is found to be damaged, it should be stopped immediately to replace the new screen;

Comparison of advantages of ultrasonic vibrating screen and ordinary vibrating screen

The ultrasonic vibrating screen is an ultrasonic energy conversion device attached to the working surface of the ordinary rotary vibrating screen, that is, the 220V, 50Hz electric energy is converted into 30±1KHz, so as to keep the screen holes unobstructed and achieve the purpose of screening and cleaning. , more suitable for the screening of high value-added fine powder. In addition, it needs to be explained in detail that the ultrasonic vibration wave (mechanical wave) attached to the screen allows the fine powder to receive huge ultrasonic acceleration, thereby inhibiting adhesion, friction, Blocking factors such as leveling and wedging can improve screening efficiency and net cleaning efficiency.

Ordinary ternary vibrating screen can screen a variety of powdery materials, and the screening effect is good. However, when sieving some silicon carbide, brown corundum, white corundum, cobalt powder, flour, medicinal powder, etc., it can be sieved in terms of working principle, but it can not meet the requirements in terms of processing capacity and sieving accuracy. In the sieving process, the ordinary screen machine is only mechanically vibrated. When the screen of the screen machine is blocked by the mesh, the ordinary screen machine cannot solve the problem, and the output will not be improved. The ultrasonic vibrating screen can just meet this requirement.

Therefore, the advantages of ultrasonic vibrating screen and ordinary vibrating screen are as follows:

1.Different screening accuracy: due to the equipped ultrasonic screening system, the screen surface has a high-frequency and low-amplitude ultrasonic vibration wave while performing three-dimensional motion, so that the material is suspended on the screen surface at a low altitude to increase the screening accuracy. The screening accuracy can reach more than 95%, while the screening accuracy of ordinary vibrating screen is generally around 60%-70%;

2.Effectively solve the problem of blocking the net: the net cleaning device of the ordinary vibrating screen is a bouncing ball, which can clean the granular materials, but for the precision powder materials or some materials with special properties, the net cleaning effect is not obvious, and the ultrasonic vibrating screen has ultrasonic vibration. The existence of vibration waves, so the screen surface can be effectively cleaned to achieve the purpose of not blocking the screen;

3.Different output: Due to the installation of ultrasonic screening system, the output of ultrasonic vibrating screen is 2-10 times that of ordinary vibrating screen when screening powder, granule and slurry materials.
