Drum Screens

Drum Screens are compact solutions for sorting different materials by particle size and for screening for desired fraction size

Kopar drum screens are a reliable and compact solution for screening sand from the bottom ash stream. This process enables recirculation of valuable sand back to the circular fluid bed boiler. As the fuels burned in boilers contain more and more impurities, challenges are generated for the bottom ash screening to receive pure sand, which is free from ash. Drum screens are also applicable for fractioning of various materials e.g. metallurgical slags.

High availability due to in-built cleaning mechanism preventing any clogging

Combination of both mechanical and pneumatic cleaning together with a unique screen drum dual layer screening method, Kopar drum screen is well suited for challenging conditions. Rotation of the drum keeps the material in constant move resulting in high efficiency and capacity. 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 high utilization rate of existing screen surface area.

Suitable for fine screening with low maintenance

Kopar drum screens are effective solutions for screening. Coarse material can be separated easily from the fine material with our drum screens.
Materials flow freely through it without build-ups. In drum screens material equally distributes onto screening surface, and that way materials flow freely through it without build-ups.
