Roller Presses –
how we support you
Köppern roller presses consist of two counter-rotating rollers that are mounted in a frame and supported by spherical roller bearings. In addition to radial loads, the bearings can also absorb axial loads, allowing the rollers to run at a certain angle to each other during operation. The fixed roller is supported directly in the press frame, while the so-called loose roller is supported against a hydro-pneumatic spring. The basic principle of the roll press is based on the loose roll. The distance between the rolls is determined by the ratio of the pressing force of the hydraulic system to the reaction forces exerted by the material to be processed and the preset "zero gap." The distance is controlled by the hydraulics according to the requirements of the respective process. This design principle ensures constant process conditions for the material in the roll gap, which guarantees uniform properties of the press discharge material.
Hot briquetting
High-temperature solutions. Maximum load capacity.
Plants and machinery
for hot briquetting
The heart of every hot briquetting plant is a specially designed roller press, built to withstand the highest temperatures and pressure conditions.
The hot iron sponge is fed directly from the reactor to the hot press. The HBI (hot briquetted iron) is forged at approx. 750°C and with a pressing force of up to 180 kN/cm. The resulting briquette strand is discharged via a chute, fed to the separator, and separated into briquettes.

Key technical data at a glance:
- Pressing force: from 25 kN/cm (e.g. for metallurgical residues with binder) to 140 kN/cm (e.g. for aluminum)
- Scalability: The required pressing force increases proportionally with the roller diameter and the size of the briquette shape
- Solutions for a wide range of feed materials and process requirements
- Various briquette sizes available
Compaction
Turning bulk material into value.
Plants and machinery
for compaction
Our compacting presses are the core component in compacting granulation plants, which are used in the fertilizer industry, among others. They compress fine-grained solids – mainly salts – between two counter-rotating, profiled rollers to form a solid material strand, known as a flake. To do this, the material is fed into the roller gap via a screw feeder and compacted under high pressure. The flake is then broken down to the desired granulate size in the crushing/screening circuit.

Compact. Consistent. Cost-effective.
HPGR for comminution
The introduction of high-pressure grinding rolls (HPGR) in the 1980s represented a groundbreaking technological breakthrough, significantly reducing energy requirements while maintaining the same product fineness—especially for the cement and ore industries.
The new application placed the highest demands on wear protection.
