Extraction and separation of fine metal oxides

After blasting, the cast parts are released from the riser and feeder. The very fine metal oxides emitted by angle grinding, sawing or cutting must be thoroughly extracted to protect personnel and product.

For larger castings, flame cutters are used. This requires a large air supply, and the filter units are designed conservatively for extracting very fine dusts. Potential explosion protection measures must be employed if dust collectors are utilized for non-ferrous metals.
