    摘要： A sealing arrangement for a shutter for a feeding chamber of a continuously operating pressure grinder. The feeding chamber is provided with an inlet opening for feeding wood batches at atmospheric pressure into said feeding chamber and with an outlet opening for feeding said wood batches into the grinding chamber at overpressure. Each opening of said feeding chamber is provided with a shutter movable between an opened position and a closed position for preventing of escape of said overpressure through said feeding chamber.The feeding chamber is provided with a fixed guide supporting the shutter during its movement between opened and closed positions. Said guide comprises two parallel support surfaces between which the shutter is slidably mounted. The distance between said support surfaces is greater than the thickness of the shutter adjacent said support surfaces so that the shutter is displaceable towards and away from said support surfaces in a direction perpendicular to said support surfaces. A sealing element is provided in one of said support surfaces in such a way that, when the shutter is displaced away from said one support surface towards the other support surface, the shutter is released from contact with said sealing element. In this way the shutter is due to the pressure difference between opposite sides of the shutter pressed against said one support surface and against said sealing element but is released from contact with said support surface and said sealing element when the pressures are equilized on opposite sides of the shutter and can be moved to open and closed positions without said contact.

    摘要： Methods and processes for producing mulch products are disclosed. A mulch product that includes a fertilizer, at least one seed, and a mulch, and methods and processes for producing mulch products are detailed. The mulch includes wood pellets formed from processed raw sawdust that has been ground. The ground sawdust is formed into pellets, such as by compression. The pellets are then crumbled to form the wood pellets to have a substantially regular outer surface that minimizes engagement with the at least one seed.

    摘要： An improved apparatus and method for manufacturing ground wood pulp from ligno-cellulose containing wood block material by forcing the block material to be ground against the end surface of a rotatably mounted grinding disc which has projecting grinding means in the shape of elevations or ridges located on the disc end surface which define grooves directed towards the end surface circumference. The apparatus includes a pressure plate for pressing the block material along a longitudinal side against the disc end surface with the fibers directed outwardly from the center of the grinding disc and toward the periphery of circumference of the disc while the fibers are separated. In this manner the fibers are oriented in the same direction as the edges of the elevations or ridges which carry the fibers radially outward and the elevation edges engage the block fibers under a movement component which is transverse to the longitudinal direction of the fibers. The elevations may be straight or radial ridges or bars arranged along the radii of the end surface. Increased fiber releasing capacity and delivery of pulp of greater uniformity and improved quality can be obtained by this apparatus.
