Simple pursuit of sieving accuracy will be at the expense of yield,
while the pursuit of large yield will decrease the accuracy.
The gyratory screener is a kind of high precision and large yield
efficient screening equipment which is specially designed for the
above problem. With the characteristics of low failure rate, low
downtime rate, low cost, and high output, high precision, high
highly efficiency, it is the classic model of our company.
This machine has the screen sides tensioning device and the ball
cleaning system, which provide the maximum horizontal amplitude,
making the qualified product screening rate reach the highest. In
addition, it has a huge screening capacity.
The screening machine can be equipped with one to five layers of
screen, which can complete the sieving from 12 mesh to 325 mesh. It
can be designed as duplex screening to make it more productive. The
design is compact and energy efficient.
The drive is installed in the lower part of the sieve machine,
which is driven by the motor through the triangle belt, making the
screen box generate vibration. In the case of almost no vertical
vibration and jump, the special gyratory motion can make the
material enter from the top of one end of the equipment and quickly
disperse in the screen surface. Affected by the thrust of the
screen surface, the material flows rapidly toward the discharge
end. The small particles go through the screen and the big
particles stay on the mesh surface, thereby complete the screening
AF series gyratory screener drives the screen box to do circular
motion through the kinetic energy generated by the high speed
rotating exciter. And it utilizes the slightly inclined screen
surface to make the material move on the screen surface and quickly
go through the mesh, achieving a high screening efficiency and a
It is also equipped with fast tensioning and automatic cleaning
screen installation system to achieve the ideal screening effect.
The fully enclosed structure conforms to the environmental
protection requirements. And there are few vertical impact loads on
the ground based on the specific movement methods, which makes the
AF series gyratory screener have a broader market application
- the unique reciprocating motion makes the whole screen surface have
the equivalent screening efficiency, which can realize the large
yield and high precision screening.
- quick-open type hinged door and rapid screen mesh tension system
ensure quick replacement and inspection of screen mesh.
- the unique suspension system makes the whole machine run smoothly.
The sieving machine itself is less destructive. The basic dynamic
load is low and the equipment does not need to be fixed.
- vibration exciter is maintenance-free within 2 years. Adopt high
quality lubricating grease, high quality sealing ring and high
quality sealing bearing.
- the dynamic balance drive increases the exciter's rotation speed
from 150~180 RPM to 300 RPM.
- the high speed rotation of the exciter improves the acceleration
value of the elastic ball, so that the elastic ball impacts screen
surface more powerfully. The screen mesh is not easy to plug,
prolonging the service life of the screen, reducing the downtime,
and ensuring the continuity of screening.
- fully enclosed structure and dust-free.
- the movement of the screen machine, the screen mesh protection
support design, and the effective cleaning of the elastic ball make
the screen service life long.
- soft running and low noise.
- larger capacity. Duplex screening is available.
- forward stretch material discharging, easy to collect.
The AF series gyratory screener shall be used according to the
following technical requirements:
- In order to reduce the impact of the material on the screen, it is
required that the distance between the material and the receiving
end is no more than 40cm or add a buffer plate.
- The dust removal port, feed port and discharge port all adopt soft
connection. It can not be rigidly fixed to the screen body. And the
gap between the sieve machine and the surrounding material shall
not be less than 300mm.
- Make sure the vibration exciter protection cover is closed and then
start the screening machine.
AF series high efficiency gyratory screener is a new type of high
standard and large capacity screening equipment. It is widely used
in chemical, metallurgical, abrasive, mining, quarrying, clay,
glass, building materials, medicine, food processing, grain,
plastics and other industries of fine classification.
It can be used for the most stringent or demanding screening
requirements of activated carbon, fertilizer, frac sand, limestone,
petroleum coke, plastic particles, polyvinyl chloride powder, salt,
