Grinding-swarf from the metal processing industry may contain metal alloys, stainless-steel and high-alloyed steel, all of which are ideal input-materials VacuDry® unit. The absence of oxygen in the VacuDry® process prevents any changes in the chemical structure of the oil, emulsions or metals during the treatment. The output material can later be sold at high prices.
Benefits of VacuDry® metal sludge plants:
- Separation of grinding/rolling oil and metals without quality losses
- No oxidation of metals due to oxygen-free process
- Low energy consumption
- Suitable for almost every industrial site because of low emissions
- High flexibility regarding differing types of waste streams
