A Cylindrical Screen

Have you saw a cylindrical screen?Do you want to learn something about it? Today I will introduce you something about the trommel screen.

Trommel screen is composed of motor, reduction unit, cylindrical drum, screen frame and sealing cover. Cylindrical drum screen is normally elevated at an angle at the feed end.

Chemical, coal, construction, gold mine, plastic,quarry,recycling, metallurgy, mineral-selecting industries, etc all can use trommel screen.

► Working principle
When material flow towards along the inclined rotating drum,materials jump and roll , the undersized material smaller than the screen apertures passes through the screen wire mesh, while the oversized material passes out at the other end of the drum.

► Advanage

    1.Steady and smooth operation.

    2.Low noise and low energy consumption.

 

 

    3.Simple structure with easy maintenance.

 

    4.Suitable to separate various materials especially poor quality of coal and coal slime.

 

    5.Equipment is fully sealed with cover in order to minimize the suspension of fine materials in the air during the operation. Low dust pollution.

 

    6.High screening efficiency due to installation of comb shape screen structure.

 

    7.Cylindrical shape of the screen provides larger surface area for the materials to in contact with. Able to handle large capacity of materials with high efficiency.

 

    8.Long life span.

 

► Features
    1.Smooth operation, low noise,low energy consumption
    2.Simple structure, convenient maintenance
    3.Trommel screen sieve can be sealed designed, no dust pollution
    4.Special screen mesh design, high screening efficiency, longer service life, less blockage

I believe if you choose it, it will bring you a big surprise and high efficiency! If you want to know more,please contact me!

Site Application of Trommel Screen and Inclined Belt Conveyors

Trommel screen and inclined belt conveyors is widely used in conveying and screening industry.They are specifically for processing bulk materials such as coal, construction material, stone, sand, compost, woodchip, soil and related products. 

In real manufacturing process, trommel screen and inclined belt conveyors are the most important parts in the production line. At the same time , it is in response to customer demand for handling larger volumes. Also, as modern production system, it can not only save energy and optimize throughput requirements, but also improve the efficiency of production and provide suitable solutions across a wide range of sectors for our customers. It is also another option to our customers to save more costs.

We have been in manufacturing belt conveyor, vibrating screen, bucket elevator, screw conveyor, scraper conveyorfor many years. With the development of our company, we will manufacture higher quality products to meet our customers’ requirements better.

The analysis of moving trajectory of trommel screen screening material

 In the process of movement of material, the screen surface has a frictional influence on it. Therefore, the material will go up along the mesh of trommel screen in a radial direction. After reaching a certain height, the material will go down automatically because its friction is less than its gravity. Moreover, the inlet of trommel screen is high while the outlet is low generally. Thus, materialin the drum goes forward in a “S” type way.

   In general, the screen in the inlet is fine screen while it in the outlet is coarse screen. And the closer the material nears inlet, the slighter the screening material is. Due to low power consumption of trommel screen, easy to achieve large scale and layout in the production process, the inletand outlet is easy to lay out. The most common production process is as following: belt conveyor / screw conveyor -----> trommel screen -----> belt conveyor / screw conveyor.
