Graphite powder ultrasonic vibrating screen is also called graphite powder vibrating screen, graphite powder rotary vibrating screen, etc., is used to remove impurities of graphite powder grading special equipment. Graphite powder ultrasonic vibrating screen is on the rack of spin vibration sieve is a set of ultrasonic system, make the graphite powder at screen not only by the spin vibration sieve the level, tilt, and force of counterclockwise vibration on the surface of the screen, the screen surface also accepts a Gao Zhenpin low amplitude of the ultrasonic acceleration, the graphite powder on the surface of the screen always stay suspended state, Prevent adhesion, friction, horizontal drop, wedging and other blocking factors, make fine powder more easily through the screen, improve screening efficiency.
