A roller press for compacting and briquetting bulk material having rollers, each comprising a core, segments arranged adjacent one another around the surface of the core, adjusting springs by which the segments are fixed on the roller core in the circumferential direction, clamping rings having frusto-conical faces on projections which abut frusto-conical faces on projections on the segments, and clamping bolts extending through the clamping rings and passing between the longitudinal edges of the segments. Each clamping ring is provided at its inner circumference with adjusting spring grooves parallel to the axis of the clamping ring and the adjusting springs for the segments extend parallel to the axis of the roller beyond the end of the segment to such an extent that they engage in the adjusting spring grooves in the clamping ring.

Roller press for compacting and briquetting of bulk material

Method and apparatus for the briquetting of metal swarf, pellets and powders on roller presses having briquetting rollers which are provided with moulding depressions on their cylindrical surfaces by which a briquette extrusion is formed having alternating briquette mouldings extending from one or other side of the extrusion and arranged in a chequerred pattern, each briquette moulding having a plane face on the opposite side of the extrusion. The extrusion is separated into individual briquettes by a surface pressure applied to the extrusion substantially at right angles to the plane of the extrusion.
