Some materials with static electricity are prone to problems such as adsorption and agglomeration when using ordinary vibrating screens. So how to use an ultrasonic vibrating screen to screen static materials? Some materials are easy to generate static electricity due to their own characteristics due to the friction between the material and the screen during the screening process. Static electricity will cause the material to clump and make it difficult to fall off the screen, which causes the difficulty of screening. Ultrasonic vibrating screen adopts advanced ultrasonic screening technology to successfully solve the screening problems of high static electricity and easy clumping, and can greatly improve the screening efficiency. Ultrasonic vibrating screen can be said to be a special screening machine for static materials! Ultrasonic vibrating screen is a derivative product of rotary vibrating screen; ultrasonic vibrating screen converts 220V50Hz or 60Hz electric energy into 37KHz high-frequency electric energy, input ultrasonic transducer, and turn it into 37KHz mechanical oscillation, so as to achieve efficient screening and cleaning. purpose. Ultrasonic vibrating screen is a traditional vibrating screen installed with a low-amplitude, high-frequency ultrasonic oscillating wave (mechanical wave) ultra-fine powder that receives huge ultrasonic acceleration, so that the material on the surface of the screen always stays in a suspended state, thereby inhibiting sticking. Screening factors such as attachment, friction, flat drop, wedging, etc., so as to solve the screening problems of strong adsorption, easy agglomeration, high static electricity, high precision, high density, light specific gravity, etc., to improve the screening of ultra-fine subdivisions Therefore, the ultrasonic vibrating screen is especially suitable for users of high-quality, fine powder. We can also connect the screen to the ground wire to lead out the current and reduce the occurrence of static electricity; we can also add antistatic agents before screening to make the screening effect better.
