What Are The Effects Of Different Layers For Rotary Vibrating Screen
Rotary vibrating screens, also known as circular vibrating screens, can be used in single or multiple layers. Some customers want to use the rotary vibrating screen for 4-layer or 5-layer screening, but the manufacturers of rotary vibrating screens generally recommend that customers use a maximum of 3 layers and 4 outlets. Fan machine, why is that? The suggestion of the rotary vibrating screen manufacturer is not unreasonable. From the conscientious merchants, the maximum is 3 layers. Of course, there are also merchants to make money to meet the requirements of users, and the 4th or 5th floor is really as good as the merchant promised. Use it? Today, the editor of the rotary vibrating screen manufacturer will explain to you the influence of the layer structure of the rotary vibrating screen on the machine:
1. The principle of rotary vibrating screen
The rotary vibrating screen uses a vertical vibrating motor as the excitation source, and the central vibration force transfers the vibration force upwards in order to force the material to rotate and jump, so as to achieve the purpose of sieving powder; the rotary vibrating screen is a high-precision fine The powder screening machine has low noise and high efficiency. It takes 3-5 minutes to quickly change the screen. The fully enclosed structure is suitable for screening and filtering particles, powder, mucus and other materials. After the rotary vibrating screen is started, its power device, namely the eccentric masses with different phases at the upper and lower ends of the vibrating motor, generates a composite inertial force due to the high-speed placement. This inertial force forces the vibrating body of the screen machine to make a revolving motion. Continuous reciprocating movement under the action of the ground, drives the screen surface to periodically vibrate, so that the material on the screen surface moves along with the screen box in a directional and active movement, during which the material smaller than the screen surface aperture falls to the lower layer through the screen hole , Becomes the under-screen material, the material larger than the screen surface aperture is discharged from the discharge port after continuous jumping motion, and finally the screening work is completed. The motion trajectory of the vibrating body of the rotary vibrating screen is a complex three-dimensional curve in space. The projection of this curve on the horizontal plane is a circle, and the projection on two vertical planes is two identical ellipses. In actual application, by adjusting the relative phase of the eccentric blocks at the upper and lower ends of the vibrating motor, the movement trajectory of the material on the screen surface can be changed to achieve different screening purposes.
2. More layers, the vibration frequency is too small and amplitude is too large
Rotary vibrating screen manufacturers generally recommend that users install 1-3 layers of screens, that is, the manufacturer recommends no more than 3 layers. According to many years of production experience and user feedback, it is concluded that the vibration frequency of materials exceeding three layers is low and the amplitude is too high. Large, the penetration rate is not as high as the fineness of 1-3 layers. The biggest drawback is that the more upward the torque is, the greater the torque will be. The lower part of the vibrating disc will slip or break, and the upper part will turn in a circle. What is more serious is the vibration of the bottom screen frame and the vibration of the porous support ball plate.
Xinxiang Dayong reminds you that when buying a rotary vibrating screen, you should communicate with the manufacturer's technology carefully. Don't blindly ask for more layers.
