A first portion has a first pattern of coarse bars and a second portion has a second pattern of fine bars. The second portion is positioned outside the first portion. The second pattern has a higher density of bars than the first pattern. The refining segment has a deflector arrangement protruding from a bar surface of the coarse bar. The bar surface faces the rotational direction. The deflector arrangement has a deflector surface directing a flow of fibrous material away from the bar surface. A refining apparatus has two opposing rotatable refining discs, separated by a refiner gap. At least one of the two refining discs has the above described patterns and deflector arrangements. | 02-24-2011 |
| 20110162814 | REFINER STEAM SEPARATION SYSTEM FOR REDUCTION OF DRYER EMISSIONS - A refiner steam separation system according to the present invention includes a blowline for transporting a mixture of fiber material from a refiner to an inlet of a steam separator. Waste steam is discharged from the separator through a waste steam outlet. Cleaned fiber material is discharged from the separator through an exit, which prevents a substantial portion of the waste steam from passing through the exit. A relay pipe communicates with the exit and a dryer duct, and transports cleaned fiber material therebetween. A resin input communicates with the relay pipe, and supplies resin therein. The resin is mixed with the cleaned fiber material prior to the cleaned fiber material being dried in the dryer duct. The present invention is also directed to a method of reducing VOC emissions generated during refining cellulosic fibrous material. | 07-07-2011 |

| 20120138250 | PULP MAKING DEVICE OF USED PAPER RECYCLING APPARATUS AND USED PAPER RECYCLING APPARATUS - A pulp making technology for realizing a used paper recycling apparatus of furniture size that can be installed in a small shop, room or the like. Having a beating machine provided with a pair of beating disks disposed oppositely to each other in a relatively rotatable manner at a close distance, this beating machine has a tiny beating gap, between the pair of beating disks, for executing the beating process of at least two continuous stages from a rough beating process to a finish beating process, and the beating gap starts at a supply port formed in a central part of the fixed side beating disk, and ends at a discharge port formed on the outer peripheral edge of the beating disks. Therefore, even in a very small beating process space contained in an apparatus space of furniture size, smooth and highly efficient beating of high processing capacity is realized without causing clogging of used paper. | 06-07-2012 |
| 20120273149 | METHOD AND APPARATUS FOR PRE-TREATMENT OF FIBRE MATERIAL TO BE USED IN THE MANUFACTURE OF PAPER, BOARD OR THE LIKE - A method and apparatus for pretreating fibre material to be used in manufacturing paper or the like, for example, by precipitating mineral substances to the fibres. During precipitation, fibre material, which is advantageously pretreated in a through-flow mixer operating on the principle of an impact mill, is fed to the precipitation reactor. Gas is led to the precipitation reactor in order to generate a gas space in the reactor. The gas contains a substance, which precipitates the mineral substance such as carbon dioxide (CO | 11-01-2012 |
