People use trommel screen to separate different grades of material such as soil, gravel, mulch, and sand. These machines work great when they are working with dry material, even if bits and pieces are large in size. Trommel screen is a very widely used machine in sorting technology. It controls garbage sorting and mineral sorting by particle size, and it has high sorting accuracy. The cylinder body of the single-layer drum screen is generally divided into several sections, depending on the specific situation, the screen holes are arranged from small to large. Multi-layer drum, from inside to outside, the screen hole from large to small.


Trommel Screen Working Principle
Trommel Screen is consist of the motor, speed reducer, gear, trommel, machine frame, hopper.
The trommel device is installed on the rack at an angle. The motor is connected with the trommel by the reducer and the coupling, driving the trommel around its axis Turn. When the material enters the trommel, due to the inclination and rotation of the roller device, the material on the screen surface is turned and rolled, so that the qualified material (materials under the screen) are discharged through the discharge port at the bottom of the rear end of the drum, and unqualified materials (materials on the screen) are discharged through the discharge port at the rear of the drum. Because the material is turned and rolled in the trommel, so that the material stuck in the screen hole can be ejected to prevent the screen hole from being blocked.


Trommel Screen Features
1.Screen holes are not easy to block.
2.Smooth operation and low noise
3.Simple structure and easy maintenance
4.Trommels can be designed with a seal cover, and it is easy to seal dust
5.High reliability of the whole machine, less investment
6.Using special quality screen, high screening efficiency and long service life.
