Working Principle of Trommel Screen, Cylindrical Screen, Rotary Screen:

The trommel screen, cylindrical screen, and rotary screen mainly consist of components such as a motor, reducer, drum device, and frame. The drum device is arranged at an incline. The motor, connected to the drum mechanism via the reducer, drives the drum mechanism to rotate around its axis. When material enters the drum device, due to the inclination and rotation of the drum device, qualified material (undersize product) is discharged through the screen mesh on the outer circumference of the drum, while unqualified material (oversize product) is discharged from the end of the drum. The SH series rotary screen drum device is sealed with a body cover, effectively preventing dust from escaping during operation and eliminating dust pollution. When replacing the screen mesh, simply open the body cover for easy operation.

Product Features of Trommel Screen, Cylindrical Screen, Rotary Screen:

1. Wide material adaptability: Widely applicable for screening various materials, whether inferior coal, coal slurry, soot, or other types of materials, screening can be carried out smoothly;
2. Simple and diverse feeding methods: The feed inlet can be designed according to the actual site conditions, whether it is a belt, hopper, or other feeding methods, no special measures are needed for smooth feeding;
3. High screening efficiency: The equipment can be equipped with a comb-type cleaning mechanism, allowing screening of materials no matter how dirty or mixed they are when entering the screening drum, thereby improving the screening efficiency;
4. Large screening capacity and easy scalability: For the same size, the circular area is larger than other shapes, resulting in a larger effective screening area, allowing materials to fully contact the screen mesh, thus the screening capacity per unit time is large. Additionally, due to its simple structure, convenient layout, and novel yet mature technology, it is highly scalable;
5. Low energy consumption: The motor power is small, only one-half to one-third of other screen types, and the operating time for processing the same amount of material is only half that of other screen types, resulting in low energy consumption;
6. Good working environment: The entire screening drum can be sealed with an isolation cover, completely eliminating dust dispersion and block splashing during the screening cycle, avoiding pollution of the working environment;
7. Low equipment noise: During operation, due to the low rotational speed and isolation from the external environment by the sealed cover, noise cannot be transmitted externally, thus reducing equipment noise;
8. Long service life and minimal maintenance: The rotary screen is composed of several circular ring screens, with a total screening area far larger than that of other screen types. Combined with high screening efficiency and short equipment operating time, it has a long service life, with few wear parts and minimal maintenance;
9. Convenient maintenance: The upper sealing isolation cover of the equipment can be removed without affecting the normal operation of the machine, making maintenance very convenient.
