DesbaTec - Model GRU-60 to GRU-3000 -Grinding Oil and Metal Swarf Recycling Units
Grinding oil-/ metal swarf for small or high quantities of grinding sludge. Do you want to recover your precious metal and cooling lubricant feedstock? - We offer the solution: The solvent extraction units of the GRU series have been designed for the de-oiling of metal swarfs. With this units metal swarfs can be de-oiled up to a residual oil content of 0,01%. First, the grinding oil mixture is flooded with solvent. Then, the oils are extracted from the solid particles using upflow classification and/ or supsension. The solvent/ cooling lubricant mixture, the so-called remains of the extraction, is separated and treated using vacuum distillation so that after the process the solvent as well as the cooling lubricant is available for reuse. The GRU series is equipped with a conical vessel* and can be installed in EX-zones 1 or 2 due to it`s explosion protected design.
Direct and automatic process
- Automatic feed of the grinding sludge/ swarfs
- Automatic discharge of the de-oiled metal swarfs
- Easy and complete discharge
- Optimal heat transfer through direct contact to the heated vessel surface
- Optimized drying of the metal swarfs
- Minimized residual oil content (up to 0,01%)
- Reduced extraction duration
- Optimized and even de-oiling also with angled or unfavourable swarf shapes
- No elaborate insertion and discharge of the metal swarfs
- No elaborate equipping, transport of the extraction filter baskets
- Minimized cleaning effort, since cleaning of the filter baskets is not necessary
Systems engineering according to european regulations
- Highest operational safety
Economic
- Optimized throughput
- Lower personnel costs
