Pellet press for pressing biogenic fibrous pellets and method for producing biogenic fibrous pellets and pellets produced by this method

摘要

Pellet press (1) for pressing biogenous fibrous pellets (11), having a rotatable ring die (4), which has substantially radial through-bores (5) and forms in its interior a pressing space (6), into the biogenic fibrous pressing material (10) can be supplied with at least one Koller (7; 8), which is arranged eccentrically to the ring die (4) and is able to roll on the inner circumference (9) such that the pressing material (10) for forming the pellets (11) through the Through holes (5) is pressed, and with at least one Ablängmittel (19) having Ablängvorrichtung (13; 14; 15; 16) which is fixed to a fixed housing part (2) of the pellet press (1) such that the Abfängmittel (19 ) is arranged at a distance therefrom in the radially outer region of the rotatably mounted ring die (4), characterized in that the cutting device (13; 14; 15; 16) has a base body (25) with a concave arcuate radial the radial guide surface (26) is arranged at a radial distance from the outer circumference of the ring die (4), so that in particular by vibrations in the region of the through hole (5) broken pellets (11) due to the centrifugal force radially outward be moved and protrude beyond the ring die (4) in the radial direction, in the region of its free end, in particular its front side, come to rest on the Radialleitfläche and by the arcuate radial guide surface (26) at a defined distance from the outer circumference of the ring die (4) Radial direction of the ring die (4) to the cutting means (19) are guided.
