Working principle and application characteristics of vibrating screen

I. Overview of the vibrating screen

The vibrating screen is a high-precision fine powder screening machine with low noise and high efficiency. It takes 3-5 minutes to change the net quickly. It is fully enclosed and suitable for screening and filtering of particles, powder and mucilage. The vibrating screen is made up of an upright motor as an excitation source. The upper and lower ends of the motor are equipped with an eccentric weight to convert the rotary motion of the motor into a horizontal, vertical, and inclined three-dimensional motion, and then transmit this motion to the screen surface. . Adjusting the phase angle of the upper and lower ends can change the trajectory of the material on the screen surface.

Second, the working principle of the vibrating screen

The basic principle is to convert the rotary motion of the motor into a horizontal, vertical, and inclined three-dimensional motion by the weight of the weight of the motor shaft installed on the upper and lower ends of the motor shaft, and then convey this motion to the screen surface. Changing the phase angle of the upper and lower weights can change the direction of travel of the material. Pay attention to the presence or absence of abnormal noise, whether each group of collars is locked, whether there is any abnormality in vibration, and whether the current is stable. Electrical protection devices should be installed.

Third, the application of the vibrating screen

The larger the particles, the faster the sedimentation. For particles smaller than a few micrometers such as viruses or proteins, they are in a colloidal or semi-colloidal state in solution, and it is impossible to observe the sedimentation process by gravity alone. The smaller the particles, the slower the sedimentation, and the more severe the diffusion phenomenon. Therefore, it is necessary to use a centrifugal machine to generate a strong centrifugal force in order to force these particles to overcome the diffusion to produce a settling motion. Various types of powder industry. Any particle, powder or mucus can be screened within a certain range.

Fourth, the characteristics of the vibrating screen

High efficiency, exquisite design and durability, any powder and mucus can be screened. Easy to change the screen, easy to operate, and easy to clean. The mesh is not blocked, the powder is not flying, and it can be sieved to 500 mesh or 0.028 mm. The unique grid design, the screen is used for a long time, the screen change is fast, and the screen can reach up to 6 layers. Impurities and coarse materials are automatically discharged and can be operated continuously. Low energy consumption, easy maintenance and no foundation installation.
