In this project, we collaborated with a customer in the biomass industry to set up an aspiration system to filter 4,000 kg of ground straw at their straw mill.

The challenge

As the length of the material could be as long as 8mm, we needed a solution that could cope with high capacity while keeping wear and tear on filter bags to a minimum. The size of the filter needed was for a 23m3 silo.

We chose a SimPact 4T-R filter, construction form 12 without cone. The filter is a total separator filter with a two-stage function.

The value

The first stage is a pre-filter for the main product volume. The second stage is the bag filter, which cleans the air. The bag filter is fitted with an inner-filter housing to protect it against wear and tear.

We added a pressure-controlled fan to allow the material to come out of the silo without the need for a cell wheel rotary valve. This solution prevents excess pressure building up in the silo.
