The trommel screen, also known as a rotary screen or drum screen, it is a mechanical screening device used to separate materials like soil, mulch, and sand ore, coal, gravel, etc., mainly in the mineral and solid-waste processing industries.
It’s designed to minimize setup time and be easy and convenient to service. We have perfected the ability to size and customize trommel screens with different materials to suit the application, such as the updated product compact sand washer.
The drum cylinder is tilted on the rack. The motor is driven by the reducer to rotate the drum unit around its axis. After the material enters the drum device, due to the tilting and rotation of the drum device, the material on the screen surface is flipped and rolled so that the qualified material (the product under the screen) is discharged through the discharge port at the bottom of the drum screen, and the unqualified material(the product on the screen) is discharged through the discharge port at the tail.
For dry material, trommel screen is turned over to make the material and the screen effectively contact, and the dry material can be quickly screened.
For wet material, the machine drives the wet material to roll, so that the materials are thoroughly mixed with the air, making them drier, facilitating screening and reducing the blockage of the screen.
The trommel screening machine is a large-scale cylindrical rotary screening device that is sieved by gravity centrifugal force. A suitable material for the drum screen
Sand stone, fertilizer, Ceramsite, Compost, Food Waste, Glass, Plastic, Topsoil, Wood Waste.
Drum screens are often used for screening aggregates in sand and gravel fields. They can also be used in coal preparation, mining, building materials, electric power, highways, metallurgy and other departments, especially for materials with relatively high viscosity.
1. Stone yard for grading of large and small stones, and separation of soil and stone powder.
2. Coal industry for the separation of lump coal and pulverized coal and coal washing (part of coal washing machinery)
3. In the chemical industry, the beneficiation industry is used for grading and separating powdery materials.
4. For urban waste sorting
The rotary screen is specially developed for power plants, coking plants, building materials, metallurgy, chemical industry, minerals, and other industries. It overcomes the problem of screen clogging in the screening of wet materials by circular vibrating screens and linear screens and improves the screening system. Yield and reliability. The sieved sand and gravel materials can be automatically separated, and are ideal materials for manufacturers such as buildings, highways and cement building prefabricated parts.

During the use process, the trommel screen runs slowly and evenly, with small impact vibration, stable operation and simple installation. It can be placed directly on a flat floor or floor and under the silo. The machine is easy to close and collect dust, has small maintenance, simple maintenance and long service life. Trommel screens are equipment commonly used in refractory materials, coal, river sand classification, and sand block classification. Do a good job of equipment maintenance to keep the…
When the trommel screen is working, it is generally matched with the crusher and the belt conveyor to complete the work. Drum sander also named trommel screen or rotary screen. It is used for the separation of lump coal and coal powder, and the separation effect directly affects the working efficiency of the crusher. In daily production, the trommel screen will inevitably have various problems, such as: screen cylinder blockage, joint shaft breakage, sieve ring deformation, etc., which seriously affect…
In the process of coal treatment, screening operations are often used to classify the size of the coal for the next industrial production. There are a variety of coal screening machine models, the most common being round vibrating screens, heavy duty linear vibrating screens and trommel screens. The drum screen is a common vibrating screen for coal. It has a wide application range and high-cost performance. It can be used for screening coal. However, the coal industry generally requires large output…
The sand and gravel separator is the core equipment of the concrete recycling system. It is mainly used to cleanse and recycle the sewage from the tanker and the sand in the residual concrete. The machine adopts foreign advanced concrete recycling technology, combines the characteristics of drum separation and spiral screen separation, and has made a lot of improvements on the wearing parts. It has simple operation, intelligent control, and the whole process is unattended and convenient. Fast, really fulfills…
The drum screen is a simple screening device. The trommel screen is easy to close and collect dust, the maintenance is small, the maintenance is simple, and the service life is long. It is a device frequently used in refractory materials, coal, river sand classification, and sandstone classification. The advantage of the trommel screen is that the structure is not complicated so that the device can be quickly operated, and when the trommel has problems, people can easily solve it.…
