    摘要: Moist municipal waste is subjected to a preliminary comminuting action to reduce the size of solid constituents to less than 100 mm, and the larger heavy particles are thereupon segregated from lighter particles which include relatively small fibrous particles and relatively large additional lighter particles. The additional lighter particles are segregated from the relatively small fibrous particles and are subjected to a severing action to reduce their size to a size not exceeding that of the lighter fibrous particles. The fibrous particles are thereupon mixed with severed additional particles, and the mixture is dried and ozonized prior to classification into larger, medium-sized and smaller fractions. At least the larger fractions are used for the manufacture of shaped articles.

    摘要: Apparatus for disintegrating-and-blowing material such as pulp, comprising a housing containing a plurality of rotatable vanes and having a discharge volute axially spaced from the vanes whereby the latter are external to the volute. The vanes are rotatably driven relative to the material disintegrating means; and the latter is located spaced outwardly from the vane outer ends and in the path of material discharged from between said outer ends, whereby such discharged material is disintegrated by impact with the disintegrating means and moved inwardly towards the vane outer ends to a location wherein the lighter disintegrated material can readily be gas blown through the discharge volute. Dam means, disclosed as being an inclined ramp and a dam wall, are interposed intermediate the disintegrating means and the discharge volute for restraining heavier undisintegrated, or only partially disintegrated, material from passing to the volute.

    摘要: Woolly wood fibers having lengths in the range of one-sixteenth to one-quarter of an inch and cross-sectional dimensions within the range of 0.1 to 0.05 mm., obtained by grinding wood chips of the order of one inch in length in a ribbed plate grinder, are digested in a continuous type of digester by heating such fibers at a temperature in the range of 220* F. to 330* F. for a period of 1 to 20 minutes in acid bisulfite, bisulfite or neutral sulfite cooking liquor. The consistency of the mixture is controlled by regulating the amount of cooking liquor which is recirculated through the digester, and the consistency of the mixture governs the speed of its flow through the digester and consequently controls the cooking time.

    摘要: A rotary groundwood mill comprising two discs arranged to face each other and rotated in their major planes about eccentrically located axes. The discs are rotated at exactly the same speeds and in the same rotational direction. The mill structure is such that a piece of wood entrapped between the discs will be subjected to epicyclic abrasion.

    摘要: A compactly configurable device that classifies material containing fiber can more reliably recover classified content. A classifier has a mesh disc with numerous holes, and separates screenings that pass through the holes from remnants that do not pass through; a defibrated material spray nozzle disposed to one side of the mesh disc sprays defibrated material containing fiber onto the mesh disc; a suction conduit disposed to the other side of the mesh disc suctions the waste screenings that pass through the holes; and a recovery conduit disposed on the one side of the mesh disc suctions the processing feedstock that do not pass through the holes and in the mesh disc and remain on the mesh disc. The mesh disc is disposed so the a position of the holes can move from a spraying position opposite the defibrated material spray nozzle to a suction position opposite the recovery conduit. The recovery conduit suctions, at the suction position, processing feedstock that was left at the spraying position.
