High-Frequency Fine Mesh Vibrating Screen
Features
High-frequency vibration of screen surface and fixed screen
box: With the vibration exciter fixed on the screen box, the
exciter force drives the vibration screen surface of the vibrating
system. With the vibration system designed in the near-resonant
working state, the required vibrating parameters can be achieved
with a smaller driving force. As the screen box is fixed without
movement, through the second damping bearing, the dynamic
load of the whole set is very small. It can be easily placed and
installed with no special foundation to be made.
High-frequency vibration of screen surface with the frequency of
50 Hz, the amplitude of 1~2 mm, and the vibration strength of
8-10 times the gravitational acceleration, which is 2~3 times the
vibration strength of ordinary vibrating screen. With high screen
surface self-cleaning ability, high efficiency, and large capacity,
it is very suitable for the screening and dewatering of fine powder materials with the feeding size limit of 15mm, and
particle grading size of 0.043-3mm.
The screen surface is composed by three layers of different flexible meshes. The bottom layer is polyurethane support
layer with steel cord and direct contact with the vibration excitation device. On the support layer, the compound
mesh boded by two layers of stainless steel wire mesh is laid in tension. The upper layer of the compound mesh is in
contact with the materials. The mesh aperture size should be determined according to the screening requirements.
The aperture ratio of the mesh is high with long service life. There are hooks installed at both ends of the mesh, which
is convenient for tensioning installation. The feeding buffer screen deck can ensure the smooth and uniformity of
materials, reduce the material impacts on the meshes (compound mesh), and prolong the service life.

The installation angle of the screen can be easily adjusted to suit different material properties and different screening
operation. As for the wet screening of the plant, the installation angle is generally in the range of 25 ±2° , and that of
the dry screening is generally in the range of 33 ±2° .
The vibration parameters of the screen are controlled by computer, and the vibration parameters of each vibration
system can be adjusted and set via software. Except the vibration parameters under general conditions, the
instantaneous intermittent intensity parameters can be set to clean up the screen mesh at any time and avoid the
mesh blocking.

The specially designed electromagnetic vibration system is mainly made of high quality rubber parts with reliable long-
term operation and low power consumption, which is only 0.15kw for each electromagnetic exciter.
Divided into single channel and double channel, single layer and multi layers, with modular design, the screen can be
flexibly designed according to the application.
With bending forming steel plates adopted for all the side plates and bulkheads of the screen box, and rectangular
tubes and profiles welded and assembled for the frame, the overall stiffness of the screen can be enhanced and the
appearance becomes more attractive.
Electric cabinet of different models can be configured according to the needs of the customers, so as to achieve
auxiliary functions such as parameter setting, remote control, process recording and fault alarm.
Application
Wet classification is mainly applied in the classification of fine materials in mineral processing with 1-5 layers; and the
dewatering series is mainly used for the dewatering of the tailings, quartz sands and slime.
