LUBRISERV Swarf Briquetting Presses for metal swarf

Why Swarf Briquetting ?

  • Additional revenue of briquettes against loose swarf
  • Low residual moisture content < 3%
  • Reduced freight costs – volume can be reduced to as little as 1/10 !
  • Recovery of coolants and cutting oils
  • Substantial reduction of storage and disposal expenditures
  • Significant lowering of fire and explosion risks

LUBRI-BRIK briquetter presses can process up to 70Kg/h (dependent on material type). Metal turnings and chips from machining operations are reduced in volume, dramatically reducing storage space, by up to 80%. The result is more room for production, easier handling and lower transport costs. The compacted metal can be sold to your scrap processor or broker usually for a higher value than loose swarf as the compaction process squeezes most of the cutting fluids from the swarf. The fluid is collected in a built in storage tank.   The LUBRI-BRIK Mini Briquetter is controlled via a PLC and touchscreen panel.


The HD swarf briquetting machines allow an extreme reduction of the volume of metal shavings arising from machine tools; the briquettes thus obtained are very high density and, apart from reducing the storing space, may be treated in the best possible way for their next transformation as they are deprived of 98% of the liquid contained in them and consequently the value of the waste materials is increased. The compaction cycle may be automated by adding a loading conveyor belt and a shredder (when the shavings are stringy). With these accessories (optional) the cycle is completely automatic, and the plant is equipped with all the sensors suitable for continuous processing. The HD70, 150, 220 and 350 versions produce briquettes working with dual opposing pistons. All the machines are equipped with a tank for collecting the waste liquid and a drain pump. The machines are electrically operated with a PLC and a touch screen. The last process stage in a chip handling system where applicable is swarf briquetting. Here a specially designed hydraulic press compacts the chips into dense briquettes. Lubriservs’ briquette presses range from just 10Kg/hour to over 300Kg/hour (dependant on material type). An investment in a briquetting press is relatively high, so a special study from case to case is recommended as to which profits can be achieved. Usually the non ferrous metals have the quickest payback so it is well worth considering if you have a significant amount of aluminium, copper, brass, alu bronze or lead.

The basic gained by swarf briquetting is the conversion of low density chips to a solid briquette. This gives important advantages for consumers of chips – better melting economy, less burn-off loss and simpler chip handling.


Briquetting of swarf and grinding fines can reduce a significant negative environmental impact as the products can be brought back in a closed cycle for reuse.

Technical data

Lubriserv have swarf briquetters for capacities up to 800 kg/hour for steel swarf and 200 kg/ hour for aluminium swarf. The compacting pressure can be over 300 bar and the motor power from as low as 3kW up to 50 kW. For briquetting of metal swarf from the machining process, the swarf must be short chips and have a rigidity of max 300 HB. If you have stringy, tangled swarf or contains solids or bar ends it may require pre processing prior to the briquetter e.g. conveyor/separator, shredding or crushing – Lubriserv will advise and can supply suitable equipment to work in tandem with your new press. The swarf briquette is processed by hydraulic briquetting with a controlled briquette length. Thanks to our briquetters high working pressure, briquettes of high density are produced, for example a density of over 2.4kg/dm3 can be achieved on aluminium 6000 series.
