CRUSHING, SCREENING AND FEEDING / Screens
Screens – Precise screening, low maintenance
The trommel screens are a compact solution for material sorting and screening for desired fraction sizes. They enable the separation of three material fractions at once, making recycling and the green transition one step easier.
With the burning of solid fuels in boilers, a considerable amount of bottom ash is produced. This ash contains impurities, making the recovery of pure, ash-free sand challenging.
Our drum screens play a vital role in this process by efficiently separating sand from the bottom ash stream. It supports the green transition by enabling the recirculation of valuable sand back to the circular fluid bed boiler.
Our centrifuges can also be used for the fractionation of other materials, such as metallurgical slag.
Suitable applications for our screens
You can freely use our screens for processing free-flowing materials, such as:
- Separation of ash and sand in power plants
- Screening of stored ash
- Fractioning of products like slags for further use
Typical features of Kopar drum screens are:
Capacity (t/h)
0,5-5
Fractions (mm)
<0,5
0,5 - 1,5
>1,5
High availability
Equal distribution of material
Kopar drum screens are an effective solution for your screening needs. With our drum screens, you can easily separate coarse material from fine material. As the material distributes equally onto the screening surface, it flows freely through the screen without any build-ups.
Unique design and structure
Our drum screens are a combination of mechanical and pneumatic cleaning with a unique screen drum dual-layer screening method, which makes them suitable for challenging conditions. Rotation of the drum keeps the material in constant move resulting in high efficiency and capacity.
In-built cleaning mechanism
All this can be achieved with very high availability as there are several automated cleaning systems comprising mechanical brushing, mechanical impact system and automated compressed air, or any combination of these. These cleaning installations keep the screen surface open, allowing a high utilization rate of the existing screen surface area.
