Definitions

  • the present invention relates to a process for the treatment of grass or hay for use as a substitute pulp, preferably in the paper industry.
  • grass is used as a filler for papermaking.
  • the grass is dried and comminuted to the extent that it can not contribute significantly to the strength in sheet formation, but as a cost effective organic filler both the surface properties and the opacity, i. the light-tightness of the paper sheet, positively influenced.
  • the raw material used in papermaking is usually pulp, waste paper or even a combination of both (in small quantities also still groundwood). Based on these available fibers, there is a desire to be able to use other fibers in the production of paper. Grass or hay as a third raw material could make a contribution here. Grass has all the basic properties required for pulp production and thus for paper production. In addition to the use of raw materials, various substances are added to the paper mill, depending on the requirements of the paper and the manufacturing process.
  • grass or hay is to be established as an additional raw material, it must be ensured that the requirements for the raw material for the production of the respective paper grade are met and a quality standard is ensured in the long term.
  • the pre-shredding by means of a bale breaker and / or shredder.
  • the pre-crushing can take place for example in a so-called Mahlbottich, the hay or grass is preferably comminuted to an average length between 120 mm and 10 mm.
  • This comminution is further preferably carried out by cutting the fibers, for example by means of a knife rotor, to the desired average length.
  • the harvest cut length of the grass or hay should preferably be no more than 120 mm to 100 mm and the moisture content of the hay should be greater than 0% to 15% during processing. Particularly preferably, the moisture content is between 8% and 10%. Furthermore, the hay should be free from mold and mold spores.
  • the grass is provided by cutting and harvesting meadow grass, sports and / or working grass, wherein especially in meadows the second or each further cut is particularly well suited, since in this case the tendency for knotting is reduced.
  • such grass has a higher protein content and is therefore preferred feed for animals.
  • the provision of grass, or in the dried form of hay, is today a normal part of a farm. Here, the grass is pressed after mowing and drying in different sized bales and stored dry.
  • the pulp is preferably fed by means of pneumatic conveyors of comminution and fibrillating grinding in a fiber mill.
  • the comminution and fibrillating grinding of the grass or hay is preferably carried out in a hammer mill for coarse fiber lengths, in a edge mill for medium fiber lengths and / or in a fine mill for short fiber lengths.
  • coarse fiber lengths have an average fiber length of between 10 mm and 3 mm
  • average fiber lengths have an average fiber length of between 3 mm and 0.5 mm
  • short fiber lengths have an average fiber length of less than 0.5 mm.
  • the edge mill has at least one, preferably three, pug rollers which continuously milled the pulp against a die, in particular a punch die.
  • the different grinding units also different matrices or screens are used, with which also the fiber length can be influenced.
  • the thus ground pulp is then defibered so that the compaction of the pulp caused by the grinding is released and the fibers are separated as much as possible.
  • This step is necessary in order to be able to screen or screen the pulp in the subsequent process stage, since otherwise a separation into different fiber lengths is not possible.
  • the fiberization and / or the separation of the fibers takes place after the grinding by means of profile rolling.
  • a roller frame with, for example, two opposing profile rollers is used, through the nip of the pulp is guided and the compacted pulp lumps are separated into individual fibers.
  • the pulp After fumigating the grass or hay, the pulp can be divided into at least three fiber-length fractions by means of a recirculating-air separator and / or eddy-current screening machine by means of viewing and / or sieving of the grass or hay, the coarse fraction having an average fiber length of between 10 mm and 3 mm average fraction has an average fiber length between 3 mm and 0.5 mm and the short fraction has an average fiber length less than 0.5 mm.
  • the pre-shredded and cleaned grass or hay is stored intermediately in a storage container before being sent for further comminution or grinding.
  • a storage container for example, have a capacity of several cubic meters and is used inter alia for buffering and a continuous supply of the grinding stage.
  • the removal of the pulp from the reservoir can also be done by means of a removal screw, wherein the transport of the pulp preferably takes place after the removal of the pulp by means of a pneumatic conveyor.
  • the feeding of the precut and cleaned grass or hay into the hammer mill, edge mill and / or fine mill takes place according to a further, particularly preferred embodiment of the present invention by means of a material dosing screw.
  • a material dosing screw When selecting the grinding unit such as the hammer mill, edge mill and / or fine mill is also to be considered that these not only shorten the fiber lengths, but also increase the surface of the grass or hay fibers such that an improved strength potential is provided. This surface enlargement of the fibers is achieved in particular by means of a defibrillating grinding of the aforementioned grinding units.
  • the fiber or grass or hay is pelleted after sifting and / or sieving the grass or hay by means of a pellet press.
  • a predetermined coarse fraction is discharged and preferably packaged in a separate filling station.
  • the transport of the crop and / or coarse material takes place after the sifting and / or sieving of the grass or hay, preferably by means of a conveying and / or mixing screw.
  • a conveying and / or mixing screw preferably by means of a conveying and / or mixing screw.
  • different fiber length fractions in particular coarse, medium and / or short fiber lengths of grass or hay, are mixed in predetermined proportions.
  • the grass or hay is moistened by means of a Wasserdosiersystems.
  • the production of the pellets is further carried out with a pellet press, in which the pulp is pressed by means of at least one pusher roll through a die, in particular a perforated die, to produce the pellets.
  • the pellets preferably have a basic cylindrical shape whose approximate circle diameter is between 40 mm and 2 mm, preferably between 20 mm and 3 mm, in particular between 10 mm and 4 mm, preferably about 8 mm or 4 mm.
  • the correspondingly shaped pellets are then carried out of the pellet press by means of a rotary valve and packed in a filling station, preferably in big bags.
  • the present invention also particularly includes the use of the corresponding pulp for the production of paper, board and / or board.
  • the basics of the process of processing grass or hay for use in papermaking, paperboard or board making are the requirements imposed by the end-user on the final product, i. the paper.
  • the initial situation is also determined by the quality and condition of the hay to be processed.
  • the paper has a high tensile strength, so must not fall below a certain fiber length in order to exploit the strength potential of the pulp as well as possible.
  • Different properties of the grass or hay fiber can be achieved by appropriate process steps.
  • FIG. 1 shows the process engineering process or the technique to be used for the treatment of grass or hay, taking into account the essential requirement parameters in paper production of the pulp to be used.
  • Grass is a commodity that is available in large quantities and, above all, regionally. Grass grows quickly and can therefore be harvested in Central Europe in two to five cuts per year.
  • the process comprises the preparation steps such as crushing, cleaning, cutting, milling, sifting, sieving, moistening and pelleting. It is not absolutely necessary to use all process steps in the preparation of the pulp and it is also possible to combine the individual process steps differently. Moreover, it is also possible to adjust the target sizes according to the requirement profile for paper production within the individual process step. For example, when cutting the pulp, this can be cut long, medium or short or in the As part of the grinding further shortened or fibrillating processed. Thus, the two process steps of cutting and grinding fundamentally differ from one another, so that the quality of the pulp to be produced can be influenced within a wide range.
  • FIG. 2 is the presentation off FIG. 1 added to the component of the starting material, ie the grass or hay.
  • the grass grass is preferably used from the second cut in the annual harvest, which should be free of mold, a residual moisture content of not more than 15% and which has a harvest usual cut length which is, for example, between 0.1 mm and 500 mm.
  • This grass or hay as described above, is fed to the process of processing grass or hay for the papermaking process.
  • hay was used, which was delivered in the form of two bundled hay bales.
  • This starting material contained long-fiber hay, ie with a fiber length of 50 to 80 mm, with dried hay fibers, a crude product moisture content of 9.3% and a bulk density of 0.07 kg / dm 3 .
  • the flow behavior can be characterized as difficult to flow.
  • the aim of the experiment was to produce evenly long fibers with the edge mill.
  • the ground hay should later be added to the paper.
  • the test result showed that the hay could be processed very well with the press type 33-390.
  • the press type 33-390 was used as a pug mill to crush the hay. In the partial experiment P 4, the hay could be disintegrated very evenly.
  • the partial experiment P 1 was carried out with a type 33-390 press, with a number of rollers of 2, a speed of 166 rpm and a speed of collapse of 2.28 m / s.
  • the die type 82112 was used, with a 1: 2.0 press ratio.
  • the feeding of the conveyor belt was done by shovels, after a material spread on the hall floor. Before pressing, the material had a moisture content of 9.3%, a temperature of 20 ° C. and a bulk density of 0.07 kg / dm 3 . After pressing, a moisture of 10.0%, a temperature of 59 ° C and a bulk density of 0.37 kg / dm 3 was measured.
  • the press was operated at a throughput of 180 kg / h. There was no cooling.
  • This sub-test P 1 showed a fluctuating press capacity (between 13 and 22 kW) due to the pulsating ejection of material through the pockets of the conveyor belt, a restless press run, partially pelleted and unstable compacts and a somewhat unevenly crushed product. The material was ejected into a big bag.
  • the sieve analysis of the final product shows FIG. 3 :
  • the particle size classes for smaller 1 mm are 31.2%, for the range between 1 mm and 2 mm for 32.6%, for the range between 2 mm and 3.15 mm for 20.1%, for the range between 3.15 mm and 4.0 mm at 8.8%, for the range between 4 mm and 5 mm at 5.5% and for larger 5 mm at 1.8%.
