- Revolver with 5 stations for high material throughput
- Pre-compression stage for feeding material into the revolver disk
- 2 opposing main press cylinders with 120 mm and 15 mm stroke
- Ejector cylinder for discharging finished briquettes from the revolver disk
- Infinitely variable adjustment of hydraulic speed for each compression stage
- Previously used for grinding sludge from metalworking
- Material bunker as a hopper with screw conveyor
- Machine completely overhauled by RUF in 2018
- New SIEMENS Simatic Touch Panel installed in 2020
- Only a few operating hours since overhaul
Very good condition

Grinding Sludge Recycling
- Significant savings thanks to coolant recovery
- Substantial disposal cost reduction by decreasing the volume and weight of grinding sludge
- Grinding sludge briquettes with minimal residual oil content may qualify as “non-hazardous waste”

Practical test on 15.01.2026 with aluminum chips
With adjusted parameters, the machine achieves a pressing capacity of 230 kg of aluminum chips per hour.
Further increases appear possible in principle, but could not be tested due to lack of material. (see video)
