Shaftless Drum Screen: a New Choice for Efficient Screening

Shaftless drum screen is a kind of drum screening and separation equipment with shaftless design.

Structural composition:

The shaftless drum screen is mainly composed of an electric motor, a reducer, a frame, a support wheel, a roller device, etc.

The inside of the roller device usually contains a multi-layer spiral layout of universal cutters, which can smoothly cut and screen all kinds of strip garbage.

Its structure also includes the transmission part, the support part and the cylinder part, which is composed of a rolling ring and a sieve surface.

Working principle:

The motor drives the small gear of the bite and the large gear of the roller to rotate, and the roller device rotates under the drive of the drive device.

When the material enters the drum screen, due to the tilt and rotation of the drum, the material on the surface of the screen will roll over. The qualified material is discharged through the discharge port on the back of the drum screen, and the unqualified material is discharged through another outlet.

Main features:

The shaftless design is convenient for wrapping materials, and the processing volume is high, which is 20% higher than that of the traditional drum sieve.

The material is turned over and rolled in the drum, and the material stuck in the sieve can be ejected to prevent the sieve from being blocked.

The cylinder adopts a fully sealed structure, which is dust-free and pollution-free, and the internal drum screen accessories are designed separately to save raw materials, have a larger screening space and more convenient maintenance.

The screening efficiency is high, which can reach more than 90%. At the same time, the structure is simple, the failure rate is low, the energy consumption is low, and the noise is small.

Scope of application:

The shaftless drum screen is mainly used for the grading of strip and strongly wound materials, such as construction waste, household waste, etc.

It is widely used in the classification of refractory materials, coal, fertilizers and gravel, as well as the screening of wet materials such as coal, coke, white ash and sand gold.

On construction sites, shaftless drum screens can be used for screening sand and stone aggregates, treatment of construction waste and screening of coal, etc.

Advantages and Prospects:

The shaftless drum sieve has the advantages of low power, low energy consumption, small space occupation, low investment cost, stable and reliable operation, high screening efficiency, large output and so on.

Strong adaptability to materials, able to screen materials of various properties, such as sticky, high humidity, dirty, miscellaneous, etc.

With the continuous progress of technology, the performance of shaftless drum sieves will be further improved, and it is expected to be more widely used in many industries such as construction, mining, metallurgy and building materials.
