more reports to screen use Use a descending sleeve block to resist the actuator, which is installed on the inner plate of the screen box: one set of electric vibration is preferably installed on the upper support of the screen box, and the micro vibrator is used. Two special vibrators are installed on the two sides of the screen box. Small specifications of the two micro motors can be used to make the vibration force smaller by adjusting the angle of the vibration. 7.2 Screen surface and its fastening pipe
7.2.1 In order to meet the needs of large-scale and large-scale material screening and coal and stone separation, the heavy-duty vibrating screen needs to have a larger cross-sectional area and impact resistance. The trapezoidal cross-section is used as the screen bar. In order to reduce noise and improve the shock rate, it can also be used. Open.
