When the materials enters the drum device, due to the tilt and rotation of the drum device, the materials on the screen surface is overturned and rolled so that the fine material is discharged through the discharge port at the bottom of the back end of the drum of trommel screen, and the coarse material is discharged through the discharge port at the tail of the drum discharge. As the material in the drum devise flip, rolling, so the materials stuck in the sieve can be ejected to prevent the sieve blocking.
Features of Rotary Trommel Screen:
1. Large screening volume, easy for large scale
Under the same size, the area of a circle is larger than that of any other shape, so the effective area of its screening is larger, materials can fully touch screen cloth, thus the screening capacity in unit time is larger. It is also easy for large scale due to simple structure and convenient arrangement.
2. High screening efficiency
It is equipped with comb-type screen cleaning mechanism, no matter how dirty and miscellaneous the materials that have entered into the screening drum during screening, thus increasing the screening efficiency.
3. Good working environment
The whole screening drum can be sealed with sealing isolation hood, thus reducing the noise of equipment, and thoroughly remove dust flying, lump splashing during screening circulation process, avoiding pollution to working environment.
4. Convenient maintenance
The upper sealing isolation hood can be taken apart, which does not affect the normal operation of machine, and allows very convenient maintenance
5. Wide adaptability of materials
The Trommel Screen is widely used in screening of various materials, regardless of fault coal, coal slime and soot and other materials, they are all screened smoothly.
