In the field of material screening, the  Ruijie mobile trommel screen has emerged as a highly versatile and efficient piece of equipment. Combining the functions of screening and mobility, it has found extensive applications in various industries. In this particle, let’s get a better understanding of mobile trommel screen.

Structural Composition of Ruijie Mobile Trommel Screen

1. Drum Screening Device

It consists of a motor, a reducer, a drum unit, a frame, a cover, and material inlet and outlet. The drum unit is installed on the frame at an incline. Driven by the motor and reducer, the drum rotates. Inside the drum, materials continuously tumble, and the screening process is completed.

2. Feeding System

Generally equipped with a hopper, and some are also equipped with a vibrating feeder. It can uniformly and stably feed materials into the trommel screen, ensuring the continuous progress of the screening work.

3. Conveying System

It includes multiple conveyor belts, which are used to transport the screened materials of different specifications to designated positions for subsequent processing.

4. Mobile Chassis

Common types include the tire - type and the crawler - type. The tire - type mobile trommel screen can be towed by a tractor and is suitable for sites with relatively good road conditions. The crawler - type has a stronger ability to adapt to terrain and can operate in muddy and rugged sites, such as mountain mines.

Working Principle of Ruijie Mobile Screen Drum

Materials are fed into the trommel screen by the feeding system. As the drum rotates, materials smaller than the sieve hole size fall onto the lower conveyor belt and are transported away, while materials larger than the sieve hole size continue to move forward inside the drum until they are discharged from the other end of the drum. In this way, the screening of materials of different particle sizes is achieved.

Features of Ruijie Mobile Screen Drum

1. High Mobility

It can be quickly transferred to different work sites. There is no need for complicated installation and commissioning processes, which can save a lot of time and labor costs. It is particularly suitable for projects with multiple operation points.

2. Efficient Screening

With the continuous rotation of the drum, materials continuously tumble inside the drum, increasing the contact opportunities with the screen mesh. This can effectively improve the screening efficiency and has a large processing capacity.

3. Wide Adaptability

It can screen a variety of materials, such as construction waste, sand and gravel aggregates, coal, and ores. Moreover, the aperture of the screen mesh can be adjusted according to actual needs to meet different screening particle size requirements.

4. Easy Maintenance

The structure is relatively simple, and the components are reasonably arranged. The screen mesh can be easily replaced, and the daily inspection, repair, and maintenance operations are relatively convenient.

Applications Ruijie Mobile Drum Screen

1. Construction Waste Treatment

It can screen construction waste such as concrete blocks, bricks, and crushed stones, and separate recycled aggregates of different specifications. These recycled aggregates can be used to produce recycled bricks, road base materials, etc.

2. Sand and Gravel Aggregate Production

It is used to screen natural sand and gravel or manufactured sand and gravel, and classify aggregates of different particle sizes to meet the material requirements of construction, road, and other projects.

3. Mine Mining

It is used for the preliminary screening of ores, separating qualified raw ores from waste rocks, and improving the efficiency of subsequent mineral processing and other technological processes.

4. Coal Industry

It screens coal to separate coals of different particle sizes, meeting the different particle size requirements of different users for coal. It can also be used for the preparatory operations before coal washing.

5. Agricultural Field

In the processing of crop straw, organic fertilizers, and other materials, it is used to screen out materials of appropriate particle sizes for subsequent deep processing and utilization.

The mobile trommel screen is one of the most important screening equipment in various industries. Ruijie can supply the drum screen customized accordingly.
