Resources are finite. Since prices are very volatile, especially for metals, it is important to take countermeasures. One such countermeasure is using high-quality briquetting presses like those produced by RUF. This lays the foundation for the best possible reuse of metal chips in the metal cycle – in line with a closed-loop recycling strategy.

Aluminium is scare at the moment; the price has risen sharply this year. However, using circular economy models made possible through high quality briquetting presses from RUF, model builders and mold makers as well as other aluminium processing companies can cut costs and secure material replenishment.

The latest addition to the RUF Maschinenbau portfolio, the low-cost RUF Formika, is a new briquetting system designed for the metals industries. Configured for small to mid sized batches in a wide range of applications, it frees a lot of storage space and simplifies logistics, making it in addition an attractive investment for production companies generating only small chip quantities.

Processing of metal chips by chip centrifuge or briquetting press? Two possibilities of efficiently processing chips and achieving added value are: Briquetting systems or industrial centrifuges. But what are the respective preconditions, challenges and benefits of each processing possibility and how high are the respective costs?

Euler Feinmechanik GmbH produces top quality aluminium products for their customers, who are mostly in the optical industry. One of RUF’s briquetting systems is adding to the contract manufacturer’s cost effectiveness in chip processing. The system, which works automatically, transforms bulky and wet aluminium chips into compact and practically dry briquettes, which can be sold as valuable secondary raw material.

Precision turning parts expert, Lauble GmbH, have in the meantime two briquetting systems from RUF, which enormously simplify the management of the inherent chips. The company has saved a lot of space since they switched from centrifugation to pressing and simultaneously reduced the logistic expenditure.

The efficiency of manufacturing companies who regularly machine steel and stainless steel is influenced by more than just the application of productive machining centers. The methods of dealing with the resulting steel chips also carry huge potential. This potential can be tapped by the application of high-quality briquetting systems, like those manufactured in various dimensions and performance classes by RUF Maschinenbau, Zaisertshofen. The modern hydraulic presses for steel and stainless steel chips operate with a specific pressing power of up to 5,000 kg/cm² and achieve throughput performances of between 30 and 3,000 kg/hour.

ZF Friedrichshafen saves large sums in two plants and reduces its environmental impact with RUF briquetting presses. In its plants in Passau and neighbouring Thyrnau, ZF Friedrichshafen AG has recovered around 1.75 million litres of valuable oil in the past twelve years by pressing grinding sludge in RUF briquetting presses. Adding to the environmental benefits, there are great economic advantages: The two presses have returned their investment in half a year and about two years, respectively.
