摘要:
A crop processing roll is disclosed for use in a forage harvester to process crop material comminuted by the operation of the forage harvester (10) before being discharged from the forage harvester. The processing roll (22) comprises an elongate cylindrical body of which the cylindrical outer surface is formed with a set of first grooves (23) extending generally lengthways of the cylindrical body, ridges (24) being defined between the first grooves (23). A set of second grooves (32, 35) is formed in the cylindrical outer surface which extend generally circumferentially (32) or helically (35) so as to intersect the first grooves (23) and pass through said ridges (24), thereby breaking said ridges into discrete teeth. The teeth defined by the intersecting first and second grooves are configured to ensure that crop material engaged by said processing roll does not migrate towards either axial one end of the processing roll.

An apparatus for grinding particulate material comprising: a roller press having a pair of grinding rollers each having a rotation axis and being arranged oppositely and parallel to define a grinding roller gab in a common plane through the axes of the rollers, and a mechanical conveying device for conveying granular material to the roller press having a proximal end and a distal end relative to the roller press, the roller press being arranged at the proximal end of the conveying device. The conveying device is arranged to constrain a flow or mat of the granular material having in a cross sectional view a rectangular shape with a mid-plane and to transfer the flow or mat of granular material directly to the grinding roller gab of the roller press in a linear transfer plane being coincident with the mid-plane and perpendicular to the common plane through the axes of the rollers.

Methods for increasing the extractable rubber content of non- Hevea plant matter that entail the use of particular forms of hammer milling and/or roller milling in an increase in the amount of rubber that can be extracted from the resulting plant matter such as by organic solvent extraction or aqueous extraction are provided. In certain embodiments, the methods are for increasing the extractable rubber content of guayule plant matter, and entail the use of particular forms of hammer milling in combination with roller milling and flaking to increase the amount of rubber that can be extracted from the guayule plant matter such as by organic solvent extraction or aqueous extraction.
摘要:
Eine Nachzerkleinerungsvorrichtung (7) für gehäckseltes Erntegut umfasst eine erste Walze (8) und eine zweite Walze (9), die einen Zerkleinerungsspalt (24) begrenzen. Die Walzen (8, 9) umfassen jeweils mehrere entlang einer Drehachse (13, 14) aufgereihte kegelstumpfförmige Abschnitte (15, 16) eines ersten und eines zweiten Typs, die sich in ihren Durchmessern unterscheiden. Die Abschnitte (15) des ersten Typs sind sämtlich an der ersten Walze (8) angeordnet, und die Abschnitte des zweiten Typs (16) sind sämtlich an der zweiten Walze (9) angeordnet.
