Chip and sludge treatment: Briquetting presses (WSpk)

Metal chips are a valuable commodity for the metal processing industry. Their recycling serves to close circuits and sustainability in resource efficiency and environmental management. The revenues from the sale of the chips are a fixed component in the operating calculation, especially since the scrap accumulation is already calculated into the production. The proper handling of dripping chips to which cooling lubricants adhere begins at the point of origin and is thus the responsibility of the producers. The cooling lubricants are returned to the circuit for economic and ecological reasons. The recovery of expensive cooling lubricants is becoming increasingly important in the context of the necessary environmental certificates. Metal grinding sludge must be expressly distinguished from metal chips. Grinding sludge are fine metal chips mixed with abrasive wear, cooling lubricant and other impurities. They are classified as “hazardous waste” according to the EU Waste List. Again, the responsibility for proper disposal belongs to the producer. This can be done through hazardous waste landfills or hazardous waste incinerators. However, high disposal costs are incurred there. A better option is to return it to the metallurgical material cycle. With FAUDI briquetting presses for metal chips and grinding sludge as well as our customized filtration systems for the treatment of cooling lubricants, we make an important contribution to disposal and treatment processes that convert expensive production waste into usable secondary raw materials.

How does a briquetting
press work?

The waste materials are fed into the metering screw by a conveyor unit. This conveys the material into the supercharger. The supercharger presses the material into the pre-compression bushing and stops there. The main press cylinder extends and compresses the material into a solid briquette under high pressure in the press bushing. The main press cylinder relieves and stops. The counter piston moves down and releases the ejection channel. At the same time, the supercharger is started up again. The main press cylinder ejects the briquette and pushes it into the ejection channel. The main press cylinder retracts. The dosing screw fills the supercharger again. The position of the pressing plunger is detected by the displacement encoder, the position of the supercharger and the counter plunger by limit switches. The releases for retracting and extending the cylinders are given according to the cylinder positions. The distance measuring system is also used to set the briquette length. If, for example, the briquette is shorter than specified, more chips are fed in by the metering screw during the next pressing operation. Thus, the filling quantity in the supercharger is constantly regulated and the briquette length is adjusted.
