What is the difference between an internal and external ultrasonic vibrating screen transducer?
Ultrasonic vibrating screen is a new type of screening equipment. The ultra-fine powder vibrating screen can screen materials up to 500 mesh or more. The output can be increased by 1-10 times. It can effectively solve static electricity, easy agglomeration, strong adsorption and light weight. Screening problems such as specific gravity are more and more popular with users. For the whole machine, every component is very important, so how should we choose the equipment that suits us?
EVERSUN machinery manufacturers explain the differences for you:
Different cleaning methods:Since the installation position of the internal displacer is in the middle of the net frame, it needs to disassemble the screen frame to clean it, and then lift the net frame to clean it.Because the installation position of the external displacer is at the edge of the grid, it is relatively convenient to disassemble and clean it;
Different installation forms：The internal displacer is directly fixed in the middle of the grid.The external displacer is installed outside the screen frame, and its extension is on the edge of the grid;
Applicable materials are different：Due to the problem of the installation position of the internal displacer, it will come into contact with the material during use, but for some conductive and corrosive materials, contact with the transducer will reduce its service life, and it will also affect the output frequency and reduce accuracy and output.The external displacement transducer is installed outside the screen machine, so there is no direct contact with the materials, so that the transducer can be effectively protected to improve the service life, screening accuracy and output.
Of course, both the built-in transducer and the external transducer have their own advantages and disadvantages, so when choosing an ultrasonic vibrating screen, choose the most suitable according to your own material characteristics.If you have any questions, please feel free to contact us at any time to customize the vibration screening equipment for your production needs.
