Introduction of trommel screen
JXSC support customized fixed and mobile/portable trommel screen (drum screen). The trommel screen can washing and screening material from 55 mm down to 6 mm, and even smaller sizes can be handled under wet screening conditions. It is the most widely used ore washing equipment in mineral processing.
Drum screen widely used in some washing & screening operation, including sand, gravel & aggregate plants and the screening of mill discharge streams. They are also used for mineral ore washing and scrubbing process, such as bauxite, alluvial gold, diamond, chrome, tantalum-niobium tin, iron, kaolin, manganese, etc. Usually combined with a wheels and gold sluice box to form a one-stop mobile gold wash plant.
Working principle Of trommel screen
Trommels are installed on a small angle to the horizontal or use a series of internal baffles to transport material along with the cylinder.
When the feeding material enters the roller trommel, due to the tilt and rotation of the trommel, the material on the screen surface is turned and rolled, so that the qualified material (under-screen product) is discharged through the outlet at the bottom of the rear end of the roller, and the unqualified material (upper-screen product) is discharged through the discharge port at the rear of the trommel.
structure of trommel screen
The drum body of the rotary drum screen is generally divided into several sections. Depending on the specific situation, the screen holes are arranged from small to large, and the diameter of the screen holes on each section is the same.
In order to improve the sorting accuracy and prevent small particles from being screened out in the large-aperture screen section, the feed material must be fully turned over in the drum screen, and the movement speed of the material cannot be too fast. The inner wall of the drum is generally equipped with a flap, which is used to lift the feed particles so that particles of different sizes have as many opportunities as possible to contact the screen holes. If the aperture meets the requirements, the particles can be sorted through the screen. In addition, the drum screen generally has strict requirements on the installation angle, usually 5°, which is mainly adjusted according to needs.
why choose JXSC trommel screen
features & Advantages Of Trommel screen
1. The screening efficiency is high, the screen holes are not easily blocked, and the operation is smooth.
2. The sieve holes are not easy to be blocked, the operation is stable and the noise is low. Simple structure and easy maintenance.
3. The portable trommel screen using special screens, high screening efficiency and longer service life can be achieved.
4. During the operation of the equipment, the noise generated by the materials and the rotating screen is completely isolated by the sealed dust cover, which eliminates the flying dust during the screening process and provides an excellent operating environment;
5. The noise cannot be transmitted to the outside of the equipment, thereby reducing the equipment noise.
6. JXSC trommel screen can be equipped with wheels to form mobile or portable equipment, which can be flexibly and quickly deployed to any site.
