Shaftless drum screen

The shaftless drum screen, also known as the drum screening machine, is a screening equipment mainly used for classifying and cleaning materials. It has a simple process layout and is mainly composed of inlet and outlet, motor, reducer, frame, drum device, etc. With different design structures, it is suitable for industries such as chemical industry, coking plant, mining, sand field, earthwork, power plant, building materials, metallurgy, and agricultural and sideline industries.

This machine is used in the fields of material specification classification, cleaning, and impurity removal to improve the quality of material screening. It needs to be designed rationally according to screening requirements. The shaftless drum screen is an updated product in the screening industry, and the new equipment highlights the shaftless design. Compared with traditional drum screens, the new equipment has the characteristics of low power, large screening capacity, low maintenance rate, and low noise!

Advantages and Characteristics

1. Used for stone specification classification and soil and stone powder screening in the quarry.

2. Used in sand and gravel fields for sand and gravel separation, sand cleaning

3. Used in the coal industry for the separation of lump coal and coal powder, as well as coal washing (a component of coal washing machinery)

4. In the chemical industry and mineral processing industry, it is used for classifying block materials and separating powdery substances

5. Used in the brick factory industry for screening materials before and after crushing clay and coal gangue.

6. Used in earthworks for the separation of mud and rock, as well as the cleaning of stones.

7. In the agricultural and sideline industry, it is mainly used for removing impurities from materials and classifying material specifications.

working principle

The shaftless drum screening machine is installed on the frame in an inclined manner, and the electric motor is connected to the drum device through a coupling through a reducer, driving the drum device to rotate around its axis. When the material enters the drum device, due to the inclination and rotation of the drum device, the material on the screen surface flips and rolls, allowing qualified materials (undersized products) to be discharged through the discharge port at the bottom of the rear end of the drum, and unqualified materials (undersized products) to be discharged through the discharge port at the tail end of the drum. Due to the flipping and rolling of the material inside the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from being blocked. The design and construction of the screen hole are also different depending on the industry and the material used!
