Stainless steel vibrating screen
for Chinese medicine powder SL1000 type circular vibrating screen GMP powder special circular screen is a vibration source driven by a vertical vibration motor. The upper and lower ends of the motor are equipped with eccentric weights to convert the rotary motion of the motor into Horizontal, vertical, and inclined three-dimensional motion, and then this motion is transmitted to the screen surface, so that the material is expanded and involute on the screen surface. Therefore, the series of vibrating screens are called rotary vibrating screens. Rotary vibrating screen has the advantages of long track of material running and high utilization of screen surface. Adjusting the phase angle of the upper and lower ends of the hammer can change the movement track of the material on the screen surface. It can be used for fine screening and probability screening of materials. Graded.
After the rotating vibrating screen is started, the power device is an eccentric block with different phases at the upper and lower ends of the vibrating motor, and a compound inertial force is generated due to the high-speed placement action. The inertial force forces the vibrating body of the sieve machine to perform the reciprocating motion, and the screen frame is vibrating. Under the action of the continuous reciprocating motion, the ground is driven to drive the screen surface for periodic vibration, so that the material on the screen surface is directionalally moved together with the screen box, during which the material smaller than the sieve surface diameter falls through the sieve hole to the lower layer. , to become a sieve under the material, the material larger than the sieve aperture is discharged from the discharge opening after continuous jumping movement, and finally the screening work is completed. The trajectory of the vibrating body of the rotating vibrating screen is a complex spatial three-dimensional curve.
The projection of the curve on the horizontal plane is circular, and the projections on the two vertical planes are two identical ellipse. In practical application, by adjusting the relative phase of the eccentric block at the upper and lower ends of the vibration motor, the movement trajectory of the material on the sieve surface can be changed, thereby achieving different screening operations.
