Tumbler screening machine and round vibrating screen produce two different motions with different advantages for screening different materials.
For vibrating screen, the vertical motion increases the particle acceleration which helps to sieve sticky or wet materials.
For tumbler screen, raw material moves through the screen surface elliptically, which helps to maintain a maxium contact with the screen surface, thus the screening precision is greatly enhanced.
Futher differences are like:
1. Round vibrating screen is up to three layers usually, and tumbler screen is up to five layers.
2. The largest model for vibrating screen is with diameter 1500mm, and diameter 2900mm for tumbler screening machine with larger capacity and higher precision.
3. Longer service life of screen mesh for tumbler screening machine due to low acceleration.
4. More option for mesh-cleaning device for tumbler screen (rotating brushes).
5. Lower noise in operation with tumbler screen.
