Structural principle of wood chip drum screen

Wood chip drum sieve is mainly composed of
motor, reducer, drum device, frame, sealing cover, inlet and outlet.

The drum sieve unit is mounted inclined on the
rack.

The motor is connected by a reducer and a drum screen device through a coupling, and the drive drum device rotates
around its axis.

When the material enters the drum device, due to the tilting and rotation of the drum device, the material on the sieve surface is flipped and rolled, so that the qualified material is discharged through the sieve of the outer circle of the drum, and the unqualified material is discharged
through the end of the roller.

Due to the flipping and rolling of the material in the drum, the material stuck in the sieve hole can be ejected to prevent the sieve hole from closing
.

The machine itself runs smoothly, the noise is low, the structure is simple, and the maintenance is convenient
.

The reliability of the whole machine is high, which can reduce the user's investment
.

Drum sieve fine workmanship, strong wear-resistant, steel frame to section steel welding, funnel volume large, welded for steel plates, can be set up five funnels respectively out of the material, funnel mouth connection, can be fed to both sides or one side, easy to pull or self-flow, improve the output, prevent blocking wear screen, delay production
.

The main structure of the drum screening machine is the screening cylinder, which is composed of several circular screens, the whole is inclined with the ground plane, and the outside is sealed by the sealed isolation cover to prevent pollution of the environment
.

The drum screening machine rotates the screening cylinder at a certain speed through the variable speed reduction system, the material is separated from top to bottom through the screening cylinder, the fine material is discharged from the lower part of the front end of the screening cylinder, and the coarse material is discharged from the tail of the lower end of the screening cylinder
.

In the process of use, the drum screening machine runs slowly and evenly, the shock vibration is very small, the work is smooth, the installation is simple, and sometimes even does not require a special foundation
.

It can be placed directly on flat floors or slabs and under
silos.

The drum type screening machine is easy to seal the dust, the maintenance amount is small, the maintenance is simple, and the service life is long
.

It is also a equipment
often used in refractory materials, coal, river sand grading, sand and gravel block grading, chemical granulation, and pharmaceutical pills.
