In the screening process of graphite powder, 200 meshes are commonly used for primary selection, and 325 meshes are used for higher-precision screening. Due to the high mesh number of graphite powder, the problem of screen blocking is prone to occur during the screening process of ordinary vibrating screens, and due to graphite The special nature of the powder can not cause leakage and static electricity problems during the screening process, so only by solving these problems can the graphite powder be effectively screened.
Ultrasonic vibrating screen converts 220v, 50HZ or 110v, 60HZ electrical energy into 38KHZ high-frequency electrical energy, which is input into an ultrasonic transducer to turn it into 38KHZ mechanical vibration, so as to achieve the purpose of screening and cleaning. The modified system introduces a low-amplitude, high-frequency ultrasonic vibration wave (mechanical wave) on the screen on the basis of the traditional vibrating screen and superimposes a high-frequency and low-amplitude ultrasonic vibrator on the screen. The ultra-fine powder receives huge ultrasonic acceleration. , So that the material on the screen surface is always kept in suspension, thereby inhibiting adhesion, friction, flat drop, and other blocking factors. Therefore, in the production process of graphite powder, an ultrasonic vibrating screen can be selected for screening.
