How we assisted Ekoinženiring


Ekoinženiring d.o.o. handles processing of organic industrial waste and has wished to add recycling waste swarf to their offer.

Since swarf contains high content of cooling oil-emulsion (app. 80%), they fall into the category of hazardous waste.

Based on their wishes we have developed a centrifuge to separate sludge from the emulsion. The new machine utilises centrifugal force and a special perforated supply crate. Due to vibrations, the crate is located inside a spring-mounted case and overpressure created by compressed air. Drive mechanism comprises of an electric motor with belt drive and frequency regulator to achieve smooth activation.

Due to this process of separation, the emulsion residue in swarf is lowered to 2–3%.

The swarf can now be sold as metal waste, while the purified emulsion can be reused in production.

Ekoinženiring d.o.o. sells about 700 tonnes of such waste products per year.
