Rotary screen is a kind of screening equipment for grading
according to the particle size of the material. It is also called
drum screening machine. Due to the simple process layout, it is
widely used in the classification of mining, building materials,
transportation, energy, chemical and other industries. It is
commonly used in the classification of medium and fine grain
materials to improve the quality.
Our company can customize various types of specifications efficient
rotary screen according to the user's different practical
The rotary screen is made up of motor, reducer, drum device, rack,
seal cover, inlet and outlet. The machine is inclined to be mounted
on the rack. The motor via reducer is connected with drum device
through the coupling, driving the drum device rotate around its
When materials enter into the drum device, because of the
inclination and rotation of the drum device, the materials on the
screen surface flip and roll, making the qualified material
(undersize product) discharge from the outlet at the bottom of the
drum, and unqualified material (oversize product) discharge through
the outlet at the end of the drum. Due to the material flipping and
rolling inside the drum, the material that is stuck in the middle
of the sieve can be ejected, so as to prevent the screen mesh from
Range of Application:
The rotary screen is mainly used for grading according to the
material particle size. It is widely used in electric power,
mining, metallurgy, building materials, chemical and other
production industries. And it is commonly used for grading of
refractory materials, coal, chemical fertilizer, sand field stone,
and for screening of coal, coke, lime, gravel mine and other clammy
materials, making the product structure more even and orderly, so
as to meet the needs of production.
Screen Drum Diameter (mm)
Motor Power (KW)
1. Small power and low energy consumption. There is self-cleaning
device in the drum. The mesh is not easily blocked.
2. Small occupation space, low investment cost, stable and reliable
operation, high screening efficiency and large output.
3. Simple process layout, convenient installation and maintenance,
4. Have strong adaptability to materials. Material that is sticky,
with high humidity, dirty and miscellaneous can be screened.
5. The feeding mode is diverse: manual and mechanical transmission.
It can produce in large quantities.
6. The center screen adopts annular flat steel ring design. With
good wear resistance, long service life, simple structure and
