    Block 3 loading and pre-compression consists of three mutually engaged screws 6-8. . They are located in the housing 1 in the same horizontal plane in parallel with each other, and their shafts 9-11 are rotatably located in the housing 1. Both side shaft 9 and 11 are made in the form of pipes.
    Organic material is to be crushed into the common working space 12 of the housing 1 and is pre-compressed on the screws 6, 7 and 8 or between the side screws 6 and 8, as well as the inner lining of the working space 12. In this case, the screws 6 and 8 are lead inlet and have the right direction of rotation, while the screw 7 is right-handed and rotates to the left.
    The shafts 9-11 of the screws are connected to the common drive 13, which is connected by means of the coupling 14 to the drive motor 15. The latter is fixed on the stand 16 and may be, for example, a conventional electric motor with a variable number of revolutions

    21 for extrusion is closed by a locking plate 27, which may also have axial openings for extrusion. The radial holes 24 and 25 extend outward in the form of a cone. The pressure spaces of the extrusion devices 20 or 21 are designated 28.
    Each of the tools 20 and 21 for extruding the high pressure grinding unit 5 interacts with an axially displaceable pressing head 29 or 30, which are placed with the possibility of free movement in the tubular shafts 9 or 11 and are connected to the piston rods 31 or 32 of the hydraulic worker cylinder 33 or 34. The stroke length of the working cylinders can be changed in a known manner.
    The slave cylinder 33 is located with the screw 6 and the extrusion device 20, and the slave cylinder 34, respectively, with the screw 8 and the extrusion device 21.
    I
    By jigs 20 and 21 for
    An extruder 35 is provided for extruding the high pressure unit 5.
    The device is mounted by means of four extension rods 36-39, having fastening nuts 40 and 41 at the ends.
    During the tests, depending on the type of material to be crushed, the diameter of the radial extrusion holes was chosen from 1.5 to 5 mm, the diameter of the pressure space 28 of the tools 20 and 21 for extrusion 50 mm, the diameter of the screws 6-8 by 200 mm.
    If necessary, with a higher moisture content of the source material, for example, branches with fresh leaves and wood waste, the inner spaces 18 or 19 of the medium pressure compression unit 4 may have one or more openings 42 (shown by a dotted line in Fig. 2), which is associated with outdoor space. Through these holes, the compressed moisture can be expelled from the device.
    The diameter d of the cylindrical pressure space 28 coincides with the diameter of the pressing head 29 or 30.
    The improved version of the tooling or extrusion (Fig. 9) differs from the main type in that, compared with the diameter d of the pressing head 29 or 30, the pressure space 28 has an increased diameter D ,. This increase in diameter or cross section is at least 10%. In the specific case, the diameter D of the pressure space 28 is 60 mm, the diameter d of the pressing head is 29 or 30–50 mm.
    The second variant of the improved extrusion tool 20 or 21 (Fig. 10) is characterized in that here the pressure space 28 is closed not by a plate, but by a locking element 43. The latter has a hollow nozzle 44 which conically tapers inward, and its internal space 45 communicates with the surrounding space. The hollow space 45 also has extrusion holes 25. The end of the nozzle facing the pressure space 28 is made in the form of a cone 46, which interacts with the conical hollow space 47 formed at the end of the pressing head 29 or 30. Between the inner lining of the device 20 or 21S a and the conical outer side surface 48 of the nozzle are formed

    an annular space 49, which functions in a manner similar to the specified embodiment (Fig. 9).
    Grinding carried out by means of tool 20 or 21 for extrusion in both variants (Fig. 8 and Fig. 9) is distinguished by the fact that in the design of the apparatus of the main type (Fig. 8) as a result of the displacement of the pressing head 29 or 30 inside the hole 24 and 25 for extrusion more and more blocked, i.e. a uniform flow rate is assumed, and in the pressure space 28 the outflow pressure constantly increases, whereas in the design of the devices of the improved version (Fig. 9) the outflow pressure in the pressure space 28 remains at the same level almost until the last moment, i.e. coincides with the initial minimum outflow critical pressure, since all the apertures 24 and 25 for squeezing during the stroke of the pressing head remain open (the forced back flow of the material in the pressure space 28 is shown in Fig. 9 with dashed arrows).
    The difference between the two variants (Figures 8 and 9) is also shown in the diagram (Figure 11), where the pressure P is shown on the ordinate axis and the pressure head L is shown on the ordinate axis. Segment 50 refers to the flow region. neither in the high pressure grinding unit 5, curve 51 to the main type of extrusion tool, curve 52 to the improved version of the extrusion tool, i.e. to adaptations 20 or 21.
    The diagram shows which processes precede the fluid state. Thus, the low pressure section 53 relates to the block 3 to the loading unit 3 and the low pressure precompression, and the segment 54 to the block 4 compression
    medium pressure. I
    0 The organic material to be ground is continuously supplied to the feed neck 2 and then transported by screws 6-8 to the medium pressure compression unit 4. Depending on the material being crushed, a pressure of 30-100 bar can be created in the total working space 12. During the test, the pressure was maintained at 50 bar.

    The diagram also shows that the working pressure in the compression unit 4 of the average pressure is almost unchanged, due to the presence of internal spaces 18 and 19 tapering in the form of a cone. The material here is accordingly compacted and falls into a fluid form in one of the devices 20 or 21 high pressure grinding unit 5. Since workspaces are 18 and
    19 of block 4, compression of medium pressure communicates with each other, screws 6-8 continuously and alternately transfer the material to be ground into devices
    20 or 21 for extrusion.
    The diagram shows that in the pressure space 28 of the extrusion device, in the construction corresponding to the main type, pressure peaks equal to 3000-4000 bar are observed, whereas in the construction corresponding to the improved version pressure peaks not exceeding 1000-1200 bar are observed. As soon as the current in the extrusion device 20 ends, the current immediately begins in the other extrusion device 21. Thus, continuous operation of the device is ensured.
    The crushed organic material leaves the extrusion tool 20 or 21 in practically uniform portions. Through the holes 24 and 25, the product is fed to the conveyor 35 and crushed.
    The rotational speeds of the screws 6-8 are selected in accordance with the properties of the starting material. For substances with a porous structure, such as wood, the rotation speed should be higher; for less porous material, such as synthetic materials and rubber waste, it is advisable to maintain a higher rotation speed. During the tests, the operating time of the hydraulic working cylinders 31 and 32 was within T5 s.
    The proposed device is a 50 auger interacting with
    a compact design that permits comminution at low energy costs.
