Extraction installation for large blast halls

The steel process generates a lot of dust, which makes it impossible to have a good view of the work. This dust will also overload the abrasive cleaner. The result is a blasting medium which contains excessive dust and will cause unnecessary wear to the installation. In addition, the large blasting hall will become unacceptably heavy, which will not benefit the quality of the final coating on the workpiece.

The dust-polluted air from the blasting space is drawn through the filter hoses via the suction tube. This air flow goes through the inside to the outside of the filter hose and is discharged at the top of the filter. This way, the dust remains on the inside of the filter hose.

At pre-set times, a PLC (programmable logic controller) activates the imbalance motors on the shaker window. Due to the vibrations, the dust is shaken off the filter surface and goes via the dust discharge funnel to a big bag. This way, the filter hoses are cleaned and are ready for use again.
