Dual Motion Rectangular Separator


Dual motion rectangular separator is specially designed by AAREAL for solid-liquid separation. It can meet the majority of sewage and wastewater treatment and tailings applications. It has the advantages of high vibration intensity, large screening area, adjustable screen box angle, compact structure and excellent performance.

     The revolutionary dual motion mode includes both elliptical and linear motion. This innovative design allows the operator to switch between two motion modes directly during the operation of the machine to meet the screening requirements of different materials, isolate solids and liquids, separate solid particles with different sizes, and remove other impurities.


1. Equipped with three vibrating motors, providing linear and elliptical motion modes. The elliptical motion is more gentle, longer service life of screen and good screening effect; the solid conveying capacity of linear motion is high, and the processing capacity is large. The movement mode can be switched during operation to meet the screening requirements of different materials.

2. The equipment has low noise. The noise of 1 meter away from the vibrating screen is ≤75 decibels.

3. The screen is fixed to a wedge-shaped block and pressed tightly. To replace the screen plate, just knock out the wedge-shaped block and press it in again after replacement, which is simple and convenient.

4. The inclination of the screen is adjustable, and the middle section of the screen can form a vortex state, which is more conducive to classification.

5. Using automatic spray system, and can set timing spray interval (optional).

6. The machine can be made up to 3 layers of screen, and filtration up to 25μm.

Advantages of Compound Motion
Linear Motion Elliptical Motion
  1. Large gravity acceleration (g), good vibration effect.
  2. Fast material passing speed.
  3. The processing capacity of the vibrating screen is large.
  1. Gravity acceleration (g) is small.
  2. The residence time of the material on the sieve plate is long, and the screening effect is good.
  3. Material concentration increases
  4. Improve the service life of the sieve plate.

Working Principle

     The dual motion rectangular separator is equipped with three vibration motors, which provide two motion modes: linear motion and elliptical motion. The rectangular wet screening machine is driven by a vibration motor installed on the frame beam. The vibration is transmitted to the sieve plate, and the material to be sieved is released to the sieve plate through the pipe inserted into the dual motion rectangular separator. The vibration of the sieve plate makes the smaller particle size (qualified particle size) pass through the sieve plate and enter the sieve bottom, and enters the next process through the pipeline installed at the bottom of the sieve. The material with larger particle size (unqualified particle size) stays on the upper part of the sieve plate, enters the groove at the front of the vibrating screen, and enters the next process through the pipe installed at the bottom of the groove.

The linear motion can generate 6G gravity acceleration, the elliptical motion can generate 5G gravity acceleration. People can choose the movement mode of the vibrating screen through the switch in the control box. The elliptical motion is more gentle, and the screen service life is longer. The solid conveying capacity of the linear motion is high.
