The rectangular separator is driven by dual vibrating motors. When the two vibration motors do synchronized and reversed rotation, the vibration force generated by its eccentric block offset each other parallel to the direction of the motor spindle, superimposing as a resultant force perpendicular to the direction of the motor shaft, thus the movement trajectory of the screening machine is a straight line.
The two motor shafts have an angle of dip in the vertical direction relative to the screen surface. Under the combined effect of vibration force and material self-gravity, materials in the screen surface do jumping movement, so as to achieve the purpose of screening and grading materials. It can be used to realize automatic operation in the assembly line.

The rectangular separator is driven by two vibration motors to do rectilinear vibration. By adjusting the installation angle of the vibrating motor, the material throwing angle can be changed to achieve the required form of production.Since the rectangular separator can make the material produce a very large acceleration, it satisfies the high production demand.
This machine is usually installed horizontally and can be also installed with elevation or downtilt to meet different production requirements.
