Grinding swarf containing metal alloys, stainless steel and high-alloyed steel from metal processing industry are typical input materials for the VacuDry® unit. The absence of oxygen in the VacuDry® process prevents a change of the chemical structure of oil, emulsions and metals during the treatment. The recovered material can be sold again in the market converting into profit through resource recovery.
Benefits of VacuDry® for metal sludge plants:
- Plant throughput capacity of 5 t/d to 250 t/d
- Separation of grinding/rolling oil and metal 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
- Highest flexibility regarding different waste streams
