Millions of Liters of Oil Recycled from Grinding Sludge ...

2020-4-16  The Thyrnau plant recycles more than 120,000 litres of oil every year. “By pressing with the RUF machine we recover between 100 and 120 tons of oil per year from the grinding sludge”, explains Johann Zinöcker. Since the oil has a density of only about 0.85 g/cm3, these masses correspond to a volume of about 120 to 140 cubic meters.
