Gyratory Vibrating Screen mainly uses an eccentric mechanism to make the screen surface reciprocate at a uniform speed. The material has a long contact time with the screen surface, and the mesh wire cuts the powder material, so the probability of sieving is large, the screening output is large, and the screening accuracy is high. The screening machine is less destructive to the structure of the material itself.
The screen box with an inclination angle of 4-9 degrees is driven by the drive box, and its motion track is horizontal circular motion at the feed end, gradually becomes elliptical motion in the length direction, and finally becomes approximately reciprocating linear motion at the discharge end.
The materials fed from the feed inlet are uniformly distributed on the entire screen surface under the circular motion of the screen body, and automatic classification occurs. As a result, the material with the smaller particle size below the material layer is quickly sieved, while the material with the larger particle size above moves to the discharge end. During the movement, since there is no agitation and vertical movement, the smaller particles are always close to the screen surface and can be screened at any time.
The movement of the discharging end and the screen body becomes approximately reciprocating linear movement, which gradually weakens the sieving effect, so that the particles larger than the sieve size quickly move in the discharge direction until they are discharged outside the machine to complete the entire screening of the material. During the screening process, the constantly beating elastic ball effectively prevents the material from blocking the screen holes and ensures high screening efficiency. The balance weight of the transmission box balances the inertial forces in the front and rear directions during the movement of the screen box, thereby ensuring the screen Smoothness of movement.
The materials flow into the first layer of screen surface to remove large particles from the inlet buffer and evenly. After passing through the first layer of screen surface, the remaining materials enter the second layer of screen surface to screen out unqualified materials, and finally flow out through the discharge port.
