RUF Metal Briquetting Systems

Steel press machine

Briquetting steel and stainless steel

Whether in mechanical engineering, the automotive industry, aviation, steelworks or foundries: steel chips accure in many machining processes. They are usually contaminated with cooling lubricants like oil or emulsions and often have low bulk densities. 

By briquetting alloyed (stainless steel) and/or unalloyed chips you streamline internal logistics, save storage space and costs and also recovers expensive cooling lubricants. A briquetting press for steel chips is therefore not only an ecological but also an economical alternative for chip processing.

Benefits of steel briquetting

  • Recovering cooling lubricants
  • Simplified internal logistics
  • Savings in storage space and costs
  • Improved order & cleanliness at the workstation or chip container space
  • Increased scrap revenue through separation of alloys

Efficiently briquetting steel chips of any kind

Our hydraulic briquetting presses operate with a specific pressing power of up to 5,000 kg/cm² and are suitable for a wide range of steel types (e.g. stainless steel, structural steel, machining steel, case hardened steel, X5CrNi18-10, tool steel, V2A & V4A, heat treatable steel or duplex steel). In each case the result is compact briquettes.

Briquetting directly at turning machines and turn-mill centres: Increased value for stainless steel Briquetting System: 18x RAP 4/3800/60x40

In the field of stainless steel machining, the customer produces for various industrial sectors such as measuring and control technology. The steel chips which accrue in the continuous 3-shift operation are reduced to small pieces directly at the processing machine and briquetted at once. This way, the different alloys can be cleanly separated, in order to achieve the highest possible marketing revenue. In addition, pressed out cooling lubricants are directly returned to the cooling lubricant circuit of the processing machine and chip logistics is significantly minimized right at the point of chip accrual. The customer now uses 18 individual RUF briquetting systems. The first one has already been in operation since 2009 and still impresses with its high uptime.


Process reliable oil recovery and space savings Briquetting System: RUF 4/2800/60S & RUF 4/3700/60x40

Christ & Heiri produce fine gearing parts of the highest precision. In this process, brass as well as steel alloys are processed. In the past, centrifuges and also competitor briquetting systems were used for chip processing. Two RUF systems replaced these in 2018, one for briquetting brass chips, the other one is used for steel chips. The machines convince with their low space requirements, high oil recovery rates and reliable operation combined with locally provided high-quality service.


Briquetting optimizes chip logistics and cutting oil recovery Briquetting System: RUF 5,5/3700/60x40, RUF 15/4000/70

With now two briquetting systems Lauble GmbH is enormously simplifying the handling of steel chips which accrue during the production of precision-turned parts. By switching from centrifuging to pressing, space is saved, large skip containers are not needed and at the same time forklift traffic is reduced considerably. The steel chips which are compacted into briquettes are largely dry, because pressing the chips reduces the amount of adhering cutting oil from 10-15 to three percent. The pressed out cutting oil is treated in order to be reused in the company's turning centres.


Internal logistics intensely simplified - costs significantly reduced Briquetting System: RB 15/3000/80

At the production plant the time needed in every shift to handle loose chips with about 16 chip trolleys was exactly analysed. It was very long. Briquetting significantly reduces the effort required for chip logistics. This is achieved with a machine equipped with a lift and tilt device and a slat-band chain conveyor for discharging the briquettes into a container. Thus 100-120 tons of steel chips per month are processed automatically, saving 60 man-hours monthly (which were previously needed for internal chip logistics). Furthermore, an additional revenue of 10 EUR per ton of briquettes is achieved. In order to prevent premature wear, high quality wear parts are used. Since its commissioning 2.5 years ago, the plant has run for about 7,000 hours.

Frequently Asked Questions

What are the requirements for producing briquettes?

In general, almost all materials can be made into briquettes. However, the chip particles should not be bigger than 50mm. The chips should not contain any impurities. For Wood & Biomass the moisture content should be less than 12 % (max 15 %).

How do I find the right briquetting machine?

We have many years of experience in briquetting which means that our experts are well-qualified to provide you with professional advice in choosing the right briquette press. We work with you to identify your individual requirements on the basis of the material in question and the production conditions. This then allows us to offer you custom-made briquetting machines or even complete briquetting solutions.

How do I get my chips into the briquetting machine?

In addition to our briquette presses, we also offer additional peripheral equipment, such as conveyors, silos or chip hoppers. These allow the material flow of your chips to be optimised, and RUF peripheral devices can also be used to enable the briquetting of your chips to be fully-automated. Your briquette press will always be individually custom-made in accordance with your specific requirements.
