Abstract: An apparatus for compacting stalk material, having a feeding device for feeding material to be pressed, having at least one pair of press drums which can be driven in opposite directions and which each have circumferential receiving grooves and compression rings in an alternate manner alongside one another in the axial direction, wherein the compression rings of one press drum engage in the receiving grooves of the other press drum, wherein at least one press drum is provided with a cavity and wherein this at least one press drum has a multiplicity of radially extending press channels in a manner distributed over the circumference, said press channels in each case connecting the groove bottom of the receiving grooves to the cavity, provision is made for the compression rings to have a circumferential profile having protrusions formed for example by radially external teeth having tooth tips.

Abstract: A rotary press is supported on a frame allowing liquid and solid receivers to be placed underneath the rotary press. The rotary press has an outer ring and an inner drum. The inner drum has an upper and lower flange with a stripper ring retained between these flanges. The flanges form two sides of the cavity where the pressing takes place. The flanges carry the solids away from the pressing zone to a discharge zone where the stripper ring expels the solids. By transporting the solids away from the pressing zone where liquids are expelled, reabsorption of the liquid is avoided. The stripper ring can move relative to the two flanges and is biased against the outer ring by the inner ring. The stripper ring applies pressure to the material to be processed and also pushes solid material from between the upper and lower flanges to fall into a receiver for the solids.

Abstract: For forming fibrous crop or like materials into self-supporting products, an apparatus comprising first and second compression members arranged so that opposed closing faces of the compression members co-operate to define the principal pressure-generating surfaces of a compression space for a charge of the material, protrusions extending from one or both of said opposed faces being effective to define walls of the compression space, and drive means operative to reduce the distance between the opposed faces of the two compression members until there is minimal separation of the two members in the vicinity of the leading edges of the protrusions.

Abstract: Roll-type pressure-treating apparatus, for subjecting sheet or web material to a uniformly high and uniform pressure across a nip, includes a pair of annular pressure rolls mounted in nip-defining relation to each other. Each of the pressure rolls has received internally thereto a crowned loading roll. The crowned loading rolls have ends which are received in journal blocks through which the pressure rolls are loaded, by compression springs. The crowned loading rolls apply a loading force to the respective inside surfaces of the pressure rolls in immediate adjacent relation to the opposite sides of the nip formed therebetween.

Abstract: The present invention is concerned with a mechanical, continuous dewartering press for a fibrous material, in which press the material to be dewatered is dewatered by compression between a perforated revolving drum and a roll revolving in the said drum so that the high compression force required in the dewatering and the high tangential force resulting from the revolving of the roll are directed by means of levers journalled on the end plates of the frame of the press onto the end plates, on which the counter-blades are also journalled.

Abstract: The present invention relates to a continuous press for pressing beet pulp and other juice-containing materials, and comprising a wheel (10, 12) which rotates about its own axis inside an eccentric rotatable ring (16) which is pressed against the wheel, and which has an inside diameter larger than the outside diameter of the wheel. The axial ends of a pressure region are closed by cheek plates (48) in the form of rings of smaller diameter than the wheel. These plates are pressed against the inside surface of a wheel rim (12) by pressure wheels (58). They prevent material from escaping from the pressing region, but being of small diameter, they allow material to be inserted and removed from the wheel-ring assembly up and downstream respectively from the pressing region.

Abstract: Water containing bark, or the like, is fed into a gap of a bark press, mounted in an inclined plane, the gap being formed between the inner face of a rotating large rigid perforated drum and the outer face of at least one of a plurality of independently rotating smaller compressor rolls. Water is expelled from the bark through the perforations in the drum. Any of the compressed bark which adheres to the drum or compressor roll surfaces is scraped therefrom, falls to the lower portion of the bark press where it is subjected to additional compressive forces and is finally collected at the lower end of the inclined bark press. The relatively dry bark, which is obtained, can be more effectively used as a fuel.
