Grinding of metals and non-ferrous metals produces fine dust particles which, even while using the most advanced production technologies, are impossible to prevent. Collecting and removing these fine dusts using suction is often required for technological, product-specific, environmental and regulatory reasons.
Handling these fine dust particles can pose a health hazard; stainless steel dust (e. g. processing of chrome and nickel) can be carcinogenic.
The potential risk of fire and explosion presents additional requirements for a suitable explosion and fire protection plan. Special precautions must be taken with light metals such as aluminum and magnesium, which possess a high Kst-value and are mostly classified as dust category St 1 - St3.
