Three times spin sieve
Rotary sieve is a kind of high-precision fine powder sieve machine. It has low noise and high efficiency. It takes 3-5 minutes to quickly change the mesh. It is fully enclosed and is suitable for sifting and filtering of grains, powder, mucus and other materials. The rotary vibration screen is powered by an upright motor. An eccentric hammer is installed at the upper and lower ends of the motor. The rotating motion of the motor is converted into a horizontal, vertical, and inclined three-dimensional motion, and this motion is passed to the screen surface. Adjusting the phase angles at the upper and lower ends can change the trajectory of the material on the sieve surface.
1. Small size, light weight, easy to move, the direction of the outlet can be arbitrarily adjusted, coarse and fine materials are automatically discharged, and can be automated or manually operated.
2. Screening accuracy, high efficiency, any powder, granule, mucus can be used.
3. The sieve net is not blocked, the powder is not flying, and the sieve can be up to 500 mesh(28 micron) filtration can be up to 5 microns.
4. Single frame design(mother type), long screen use, easy to switch, only 3-5 minutes, simple operation, easy to clean.
5. No mechanical action, easy to maintain, can be used in single or multiple layers, and the contact with the material is made of stainless steel(except for medical use).
The three-time rotating vibration screen is powered by an upright motor. An eccentric hammer is installed at the upper and lower ends of the motor. The rotating motion of the motor is converted into a horizontal, vertical, and inclined three-dimensional motion, and this motion is passed to the sieve. surface, This series of vibration sieves is called spin sieves because the material is moved on the sieve surface to make the outer spreading involute. Rotary sieve has the advantages of long track of material operation, high efficiency of sieve surface, adjust the phase angle of heavy hammer at the upper and lower ends, and can change the motion track of the material on the sieve surface. It can perform fine sieve and probability sieve on the material. Wait.
After the vibration sieve starts to move, its power device, the eccentric block with different phases at the upper and lower ends of the vibration motor, produces a composite inertial force due to the action of high-speed placement. The inertial force forces the vibration body of the sieve to make a double-spin motion, and the sieve frame is under the action of vibration. Continuous reciprocating motion, Enter the ground and drive the sieve surface for periodic vibration, so that the material on the sieve surface can be actively moved together with the sieve box. During this period, materials smaller than the aperture of the sieve surface fall into the lower layer through the sieve hole and become sieves. The material larger than the aperture of the sieve surface is discharged from the discharge gate after continuous jumping and finally completes the screening work. The trajectory of the oscillator is a complex spatial three-dimensional curve. The projection of this curve on the horizontal plane is circular, and the projection on the two vertical surfaces is two identical ellipses. In practice, by adjusting the relative phase of the eccentric block at the upper and lower ends of the vibration motor, the trajectory of the material on the sieve surface can be changed, so as to achieve different screening purposes.
