Trommel Screen

Brief Description

Trommel screen is a special screening equipment developed for power plants, coking plants, building materials, metallurgy, chemical industry, mining and other industries. It overcomes the problem of clogging of wet vibrating materials in circular vibrating screens and linear vibrating screens. The output and reliability of the screening system have been well received by users.

The roller screen is made up of five parts: roller, frame, funnel, reducer and motor. After the broken stone enters the roller, the material is sieved by the centrifugal force of the drum rotation and the jigging action. Screened out one by one through screens of different meshes. The stones of different specifications are sieved out and dropped into the belt conveyor through the funnel to be sent to the finished material yard. On the one hand, it is screened as the roller rotates, and the material is sieved by the centrifugal force of the drum rotation and the jigging action. On the other hand, the coarse-grained stone flows forward along the slope of the roller, and is gradually screened out through the screen of different meshes.

The roller screen machine mainly consists of a motor, a reducer, a roller device, a frame, a sealing cover, and an inlet and outlet. The roller unit is mounted obliquely on the frame. The motor is coupled to the roller unit via a coupling through a reducer to drive the roller unit to rotate about its axis. After the material enters the roller device, due to the tilting and rotation of the roller device, the material on the screen surface is turned over and rolled, so that the qualified material (the product under the sieve) is discharged through the screen of the outer circle of the roller, and the unqualified material (the product on the sieve) ) is discharged through the end of the roller. Due to the turning and rolling of the material in the roller, the material stuck in the screen hole can be ejected to prevent the screen hole from being clogged.

Feature & Benefits

1. The mesh hole is not easy to block.

2. The roller support adopts the integral through-shaft structure, which runs smoothly and has low noise.

3. Simple structure and convenient maintenance.

4. According to the screening needs, a fully enclosed structure or an open structure can be adopted; wherein the fully enclosed structure is easy to close the dust collection and change the polluted environment.

5. The process layout is flexible, and it can be combined with screens of different specifications, and it is easy to adjust and replace.

6. Adopt special screen, high screening efficiency and long service life.

7. It has strong adaptability to materials, and materials with various properties such as viscosity, humidity, dirty and miscellaneous can be screened, and the feeding mode is flexible;

8. Less wearing parts, small maintenance, and convenient maintenance;

9, because of the low speed, stable work, can be installed in the upper layer of the equipment, and easy to achieve large-scale.




Roller screen is suitable for screening materials of various properties as well as coal, coke, white ash and other wet and easy to block materials, stone fields and other industries, the material is <100mm, the middle 10~50mm, the finer can reach ≤3mm or less.

1. Stone yard for grading of large and small stones, and separation of soil and stone powder;

2. Separation from sand and gravel in the sandstone field;

3. The coal industry is used for the separation of lump coal from pulverized coal and coal washing (part of coal washing machinery);

4.the chemical industry, the mineral processing industry for the classification of large and small blocks and separation of powdery substances.
