摘要： A centrifugal grinder has an internal grinding surface shaped as a surface of revolution, and a rotor mounted within the surface for rotation about the axis of the grinding surface. The rotor defines a generally axial inlet passageway for wood chips to be ground, and at least one pocket extending generally outwardly from the axis of the rotor toward the grinding surface. The pocket is provided with a configuration such that its cross section increases at an increasing rate away from the rotor axis. This encourages the wood chips to orient themselves parallel to the grinding surface, such that they take up such parallel orientation by the time they reach the grinding surface.

摘要： The speed of feed movement of a piston is controlled to an essentially constant value by direct digital measurement of the actual speed, by comparing the actual value to a preset value and by compensating for differences therebetween. Variations in the piston feed pressure and in the grinding power are taken into account by means of additional signals related to these factors and added to or subtracted from the signal representing the actual value of the speed of the piston.

摘要： The disclosure concerns both a process and an apparatus for producing wood pulp. Wood to be pulped is fed into a housing where the wood is ground. The housing is pressurized above atmospheric pressure. Water at a temperature over 100.degree. C. is fed to the pressurized housing in the grinding zone. The wood pulp produced by grinding is collected and is conveyed through a worm conveyor which causes the water in the pulp to be removed therefrom, while the pulp and the water removed therefrom are maintained at elevated pressure. The water under pressure is returned to the grinding zone in the housing. The wood pulp is thereafter returned to atmospheric pressure. Various pressure lock devices for transmitting the wood pulp from being under pressure to atmospheric pressure are disclosed including a nozzle, a pressure lock device, a hydrocyclone and/or a disc refiner.

摘要： A method of regulating a grinding process in a pocket grinder pressing a wood batch in at least one pocket against a rotating grindstone with a grinding plate movable in the pocket calculates the apparent pulp quantity produced at measuring points at fixed intervals of the grinding stroke and changes in the wood batch density which occur during the grinding stroke. The value thus calculated is compared with a target value for the pulp quantity to be produced and the grinding process regulated thereby to reach the target value. To make the pulp quantity produced as even as possible, the calculated value of the apparent pulp quantity produced is corrected in relation to the hydraulic pressure used during the grinding stroke.

摘要： A method of controlling a grinding process in a pocket grinder in which a batch of wood in at least one pocket is pressed against a rotating grindstone by a pressure shoe displaceable in the pocket. At predetermined intervals an apparently produced amount of pulp is calculated at separate measuring points of the grinding stroke of the pressure shoe and the specific energy consumption calculated on the basis of this amount of pulp is compared to a target figure for the specific energy consumption. The batch grinding is adjusted depending on a deviation of the specific energy consumption from the target figure. The compaction of the batch in the pocket during the stroke of the pressure shoe is taken into account in the grinding adjustment by correcting the calculated apparently produced amount of pulp in relation to a change in the density of the batch to be ground so that the fluctuations in the fineness of the pulp produced at separate measuring points of the pressure shoe are maintained as small as possible during the grinding stroke of the pressure shoe.
