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.

Metal Trade Comax operates an aluminium melting plant for recycling aluminium scrap to produce various aluminium cast alloys. The basis for this is defined aluminium scrap. A large share of that is delivered to the Refiner as loose chips. Before these are loaded into the furnace, they are processed and then pressed into briquettes with automated RUF briquetting systems. The briquetting of the chips, in particular, ensures optimised metal yields and therewith a markedly increased profitability.

RUF's briquetting technology helps the automotive supplier ZF Gusstechnologie GmbH to shape its processes in a more efficient way. With the help of RUF units, the pressure die-casting specialist presses the aluminium chips, which arise when working on passenger car gearboxes and gear parts, into solid briquettes and, at the same time, frees them to a great extent from adhesive cooling lubricants. This means the company saves a lot of space and logistics expenditures, avoids lubricant carryover, protects the environment and raises the sales revenues from the aluminium chips.
