  • Patent number: 5984214
    Abstract: A multiaxes roll type of crusher comprises four rolls. The four rolls respectively have teeth for directly crushing materials. There would be virtually 6 pairs of rolls in mathematically. There are really at least three relations given for crushing. Raw materials are crushed with a first crushing-relation to be of smaller size. Such crushed materials are secondly crushed with a second crushing-relation and a third crushing-relation to be of still smaller size. The first roll and the second roll can rotate in reversely opposite directions. The third roll and the fourth roll can rotate in reversely opposite directions. The reverse rotations cancel the crushing-relations. The flow of the crushed materials are controlled by a flow controlling means, which opens and closes the path between the third roll and the fourth roll. The opened flow controlling means does not obstruct the flow of foreign materials between the third roll and the fourth roll.

  • Patent number: 5970582
    Abstract: A method and apparatus for separating kenaf into fiber and core uses a modified stick machine conventionally used in the cotton industry for removing trash from unginned cotton. Lengths of kenaf are delivered onto the periphery of a saw cylinder so the toothed wheels snag the fiber and draw the kenaf across a grate. Core is detached from the fiber, passes through the grate and is delivered to a core outlet. Fiber on the toothed wheels are removed by a doffing wheel and delivered to a fiber outlet. Multiple saw cylinder/doffing wheel assemblies are provided.

  • Patent number: 5544823
    Abstract: The invention is directed to a new method for producing milled grain products such as flour, semolina, middlings, etc., wherein the material is repeatedly ground by means of rolls and sifted with the system of advanced milling. It is suggested that the material be guided again at least twice via double-roll grinding stages with sifting between the double grindings, wherein the material is sifted in each instance following the double grinding. In an especially preferred manner, a corresponding new mill with at least two double-grinding passes is preferably constructed as an 8-roll mechanism (70). In an especially preferred manner. the new mill comprises a combination of eight- (70) and four-roll mechanisms (142, 151).
