With the introduction of a RUF briquetting press Keiels Formenbau GmbH have simplified their working processes substantially, as well as massively reducing their costs. The briquetting system can press 50 kg per hour of Aluminium chips, which are produced during milling, into solid briquettes. When compared to the sale of loose, wet chips the company has doubled its revenues through selling Aluminium briquettes. In real terms this is a return on investment in about a year.

One of RUF´s heavy duty briquetting systems is contributing enormously to efficient work processes at SWG Metallverarbeitung und Montagetechnik GmbH. The press reduces the volume of chips to almost a tenth of the original volume as well as recovering valuable cooling lubricant and is not knocked out of its stride by even the coarsest particles which can be found between the chips. In the meantime almost one million aluminium briquettes have been pressed by the RUF press at SWG.

By pressing loose chips of stainless steel into briquettes, EZ Zerspanung GmbH was able to lower its costs for cutting oils significantly and reduce environmental impact. Through the process of briquetting the turning parts expert can retrieve about 80 percent of the cutting oil adhering to the chips. This saving is the main reason why the RUF-briquetting press amortised itself within less than three years.

Zollner AG compresses more than 100 tons of aluminium chips per year using a RUF briquetting press. The mechatronics service provider thereby reduces the volume of this recyclable material to a fraction and isolates clinging oils and emulsions. By recovering cooling lubricant and thanks to increased prices for aluminium briquettes, the press has amortized itself within a very short time.

With a briquette press, GFC Antriebssysteme GmbH was able to significantly reduce their production costs and design the disposal of grinding sludge and millings in an environmentally friendlier manner. The Saxon specialists for worm gears press almost 30 tonnes of expensive cooling lubricants from sludge and millings annually using a system from RUF, and recycle them. Better waste prices are also the target for the remaining, largely oil-free metal briquettes as would be the case for loose millings. Under the line, the investment will amortise itself in only two years.

A manufacturer of roof systems, Bauder has avoided high transport costs by running RUF briquetting presses. At this Stuttgart company, the dusts generated by cutting and milling operations on rigid polyurethane foam boards are pressed into compact briquettes. A subsequent processor then retrieves the briquettes which it then reuses as a valuable raw material. In bulk form, these dusts would entail high transport costs.
