What Are the Advantages of a Trommel Screen

The biggest difference between a trommel screen and other screening equipment is that it does not rely on a vibration motor to generate excitation. Instead, trommel screens are classified into shaft trommel screens and shaftless trommel screens according to their drive method.

Shaft Trommel Screen: The motor drives the trommel unit through a reducer and coupling, causing it to rotate around its axis. This motion makes the material on the screen surface tumble continuously, effectively preventing screen clogging. It is commonly used for separating irregular, blocky materials.
Shaftless Trommel Screen: Designed with a shaft-free structure and offering multiple drive methods such as chain drive, gear drive, or roller support drive. With a larger screening space, its processing capacity can increase by nearly 20%.

Key Advantages

Wide Screening Range: Capable of handling various wet and clog-prone materials from mining, power plants, coking plants, building materials, metallurgy, chemicals, quicklime, and hydrated lime.
High Screening Efficiency: Equipped with a comb-type cleaning mechanism, which ensures effective screening regardless of how dirty or contaminated the incoming material is.
Large Screening Capacity: Material is fully exposed to the screen mesh, resulting in higher throughput per unit time.
Environmentally Friendly & Low Noise: The entire machine is sealed with an isolation cover to reduce environmental pollution. The trommel rotates at a low speed, ensuring smooth operation and reduced noise levels.
