Project details

For the expansion of the waste wood recycling plant of Swiss Krono in Switzerland, LHS supplied a turnkey solution for the extraction of the resulting dust. In the process, two old circular filters were replaced and a new crushing plant was also integrated. The dedusting plant was put into operation in November 2019.

Operating principle

The recycling plant exhaust line was rerouted from the old round filters to the new bag house filter and the old round filters were removed. The individual extraction points of the new crushing plant were piped and connected to the filter. A new fan was installed for each of the two extraction systems. The filter itself is divided into two sections, each discharged via a screw and subsequent rotary valve. Both strands are combined and fed onto a vibrating screen to separate coarse and fine fractions that can be recycled.
