Step 1: There are various type of dust extraction machine: bag type bag house filters, cartridge type dust collectors, sinter-plate dust collector, wet scrubber and cyclone or cyclone+ filter two stage dust extraction solutions. Before we choose the dust collector, firstly we need to know are the dust material’s characteristics: flammable? Sticky? Density? Moisture?... and the other appendix needed. So we need to write the process summary sheet to know the main conditions to help us choose the suitable filters. Sometimes we need some pictures and videos. Appendix download 1: process summary sheet
Step 2: after choose the suitable filters, we need to calculate the airflow/air volume and the pressure the exhaust centrifugal fan needs. And the air flow depend on the extraction hood, the pressure must overcome the ducts and duct collector’s pressures.
