The straight discharge vibrating screen, also known as the straight unloading vibrating
screen, uses one or two horizontal vibrating motors as the excitation source The
vibrating motor is placed on one side of the body (two vibrating motors are located on
both sides of the body). After the material enters the interior of the, it makes an elliptical
motion trajectory under the action of the vibration source, moving quickly and reciprocally.
While completing the action of passing through the net the vibration force can
continuously strip, disperse, and reorganize the material, thus allowing the material to
quickly pass through the net. The material that cannot through the net is discharged from
the discharge port on the screen according to the movement trajectory of the equipment,
completing the screening operation process.
 

 

 
The working principle of the straight centrifugal sifter mainly relies on the vibrator
motor. The two sets of eccentric blocks (unbalanced eccentric blocks at the upper
and lower ends of the vibrator motor shaft convert the rotational motion of the
vibrator motor into a combination of horizontal, vertical, inclined, and centrifugal.
These forces are then transmitted to the screen surface to achieve the purpose of
sieving. By changing the phase angle and weight of the upper and lower eccentric
blocks the magnitude of the exciting force and the trajectory of the material
movement can be adjusted.

 

 
1. High efficiency screening: The inlet and outlet of the straight sieve are designed in
the same vertical direction, and the large flow outlet at the allows the material to be
directly discharged, resulting in a fast discharge speed and a production rate that is
2-5 times that of a conventional round sieve.
 
2. Automatic discharge: The double-source straight discharge screen can produce
vortex motion on the screen surface, which has the function of automatic discharge.
 
3. High space utilization: Since the motor is designed outside the equipment, it reduces
the equipment height and effectively utilizes space.
 
4. Environmental protection operation: fully enclosed structure, eliminating dust flying,
low noise, quiet and environmentally friendly.
 
5. Easy to maintain: simple and compact structure, convenient maintenance, and minor
faults.
 
6. Versatility: It can be modified according to different usage conditions, such as raising
the feed port or adding a butterfly valve, to meet production needs.
