摘要： Method and apparatus for producing cellulosic pulp by the thermo-mechanical pulping method wherein wood chips are contacted with gaseous steam at a temperature and for a time sufficient to bring the temperature of the chips close to that of the steam, compacting the resulting steam treated chips while mechanically conveying the same to reduce the moisture content and produce a compacted moist mass, shredding the compacted mass while further conveying the same under more severe conditions than the original conveying and then passing the shredded mass into a refiner. The apparatus of the present invention preferably takes the form of a pair of coaxially operating worm-type conveyors with the end of one conveyor being journalled in the end of the other, and operating under conditions such that the second conveyor tends to pull the compacted mass faster than it is being delivered and thereby provides a shredding action to maintain a fairly uniform input into the refiner stage.

摘要： An arrangement in a pulp grinder comprising a grindstone (1), a feed chute (2), and a piston to feed wood (3) against the grindstone (1). The arrangement comprises separate pushing members (6), which are arranged to push the wood (3) against the grindstone (1) at essentially the entire width of the feed chute when the percussion piston is moved back to the stroke position to allow the feed of a new batch of wood.

摘要： An arrangement in a pulp grinder comprising a grindstone (1), a feed chute (2) extending to the grindstone, a piston (5) moving in the feed chute, an auxiliary piston (6) and closing members (7). In the arrangement, there are recesses on the front of the piston (5) and apertures in the auxiliary piston (6) so that the closing members (7) can be pushed from both sides of the feed chute (2) through the auxiliary piston to the recesses of the piston so that they settle behind the wood pressed by the piston.

摘要： An arrangement for providing continuous grinding in a pulp grinder comprising a feed chute and a piston in the feed chute moving lengthwise of the feed chute for pressing the wood in the feed chute against a grindstone. The arrangement comprises rotary feed members (6) between the piston (5) and the grindstone (1) on the sides of the feed chute (2) for pushing the compressed wood (3) further against the grindstone (1). Also, the arrangement comprises a closing member (7) that can be pushed between the compressed wood (3) and the piston (5) to prevent the wood (3) from moving backward with the piston (5) as the piston (5) is moved to the initial position, ready for the stroke, to allow the feed of a new batch of wood.

摘要： A refiner for the manufacture of cellulose pulp where the raw material is processed in a gap between two opposed refining members rotary relative one another, and where at least one of the refining members is supported on a rotary refiner shaft (2) driven by a motor (4). An intermediate shaft (3) is connected non-rotary to a first and, respectively, second coupling (6 and, respectively, 7) between the rotor shaft (5) of the motor (4) and the refiner shaft (2) for transferring the drive moment. For damping the torsion oscillations in the mechanically connected shafts (2, 3, 5), an outer pipe (8) stiff against torsion is provided concentrically with the intermediate shaft (3), and one end of the pipe (8) is rigidly connected to the first coupling (6) at one end of the intermediate shaft, and the other end of the pipe (8) is connected by means of a friction damper (9) to the second coupling (7) at the other end of the intermediate shaft.

摘要： In order to achieve a uniform quality of the pulp the rate of feed movement of each piston is controlled to an essentially constant value by direct digital measurement of the actual rate of feed movement, by comparing the actual value to a present value and by compensating differences therebetween. Variations in the piston feed pressure and in the grinding power are preferably 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 rate of piston feed movement, depending on the situation.
摘要翻译：为了实现纸浆的均匀质量，通过将实际值与当前值进行比较并通过补偿差异将每个活塞的进给运动速率控制在基本恒定的值，通过直接数字测量进给运动速率其间。活塞进给压力和磨削功率的变化优选地通过与这些因素相关的附加信号考虑并且根据情况加到或减去代表活塞进给运动速率的实际值的信号。
