Metal Sludge Plants for Oil and Metal Industry - Metal

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.

  • 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

  • Sources: Subtractive manufacturing of metal parts, filtration of cutting fluid for metal works, metal-rolling mills, steelworks
  • Input material: Grinding swarf – high-alloyed steel, high carbon steel, stainless steel and carbon steel; mill scale, metal powder sludge
  • Output material: Oil, water, oil free metal briquettes; TPH below 1000 ppm, 100 ppm possible
  • Plant design: Fixed or mobile execution, 0.5 … > 5 t/h throughput capacity
  • Heating system fired by: Fuel oil, diesel, natural gas, biofuels, electricity, recovered mineral oil fraction
  • Optional: Briquetting of recovered metal powder
