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.
* On request, the GRU also can be delivered with a horizontal lying vessel with extraction filter baskets.
(1) depending on solvent, oeprating conditions, level of contamination and water content, (2) higher temperatures possible, (3) further on request, (4) depending on residue container, (5) vacuum system for up to 1mbar possible, (6) process liquid H2O at 15°C, at 50Hz, (7) at max. 15°C, (8) integratable on request
The technical data stated above are to regarded as orientation, as every unit is built and developed according to your wishes and requirements. Changes, errors and omissions excepted. Photos can differ from actual quotation.
