Definitions
- the invention relates to a grinding roller of a high-pressure roller press, comprising a shaft, wherein the shaft rotationally symmetrical respect. a rotation axis, and at least one wear-resistant bandage, wherein the shaft and the at least one bandage are coaxial with each other and wherein the bandage is shrunk frictionally on the shaft in a longitudinal portion of the shaft.
- the invention further relates to a method for separating a bandage and a shaft in such a grinding roller and a method for frictionally connecting a bandage and a shaft to such a grinding roller, wherein the bandage and the shaft are designed with respect to their diameter in interference fit.
- Grinding rollers are used as part of high-pressure roller presses (roller presses, high-bed roller mills) for the comminution of granular regrind, for example.
- high-pressure roller presses roll presses, high-bed roller mills
- a roller gap is formed between two grinding rollers, in which grinding material is drawn in by the two counter-rotating rollers and in which the material to be ground is crushed under high pressure.
- scratches and micro-machining by the brittle regrind can lead to abrasive wear of the surface and outer layers of the roller.
- measures are taken to protect against wear.
- the grinding roller is viewed from the inside to the outside from a shaft that is in the high pressure roller press is stored accordingly, and a coaxial bandage constructed (see, for example, the DE 20 201 1 1 10 190 U1).
- the bandage is made of wear-resistant material, especially made of suitable steel, protects the shaft against abrasion in the area of special grinding stress and often promotes the grinding process by means of a profiled surface. After a certain period of operation occurs in the bandage wear on, but does not need the shaft or the entire grinding roller to be replaced. Rather, it is sufficient an exchange or a workup of the bandage.
- Such thermally permissible withdrawal of the shaft and the process of shrinking also lead to a heating process for the shaft.
- the process of disassembly (but also the assembly) can be significantly promoted by the fact that the shaft is cooled thereby.
- the shaft does not expand to the same extent as the heated bandage, so that it comes to a more incoming solution of the compound than without cooling the shaft.
- the shafts are provided with a central, i. provided along the axis of rotation arranged cooling hole.
- the external heat on the bandage must be increased in order to promote a solution of the connection;
- the temperature range raised in this way is not gentle on the material, since structural changes or phase transformations can occur in alloys such as steel even at a few hundred degrees Celsius over time, which reduces the resistance of the grinding roller to the forces acting on it during the grinding process.
- This is exacerbated by the fact that, with central cooling, the process of releasing (as well as producing) the frictional connection slows down as the size of the rolls increases. This not only means longer and more energy-intensive operations, but also a longer period in which the mentioned phase transformations can occur and take place.
- a temperature-related significantly stronger cooling in the central area would not only be economically intensive, but would also lead to large temperature gradients in the radial direction within the shaft itself, which also, for example, by tensions, contribute to material weakening.
- Cooling which are based on cooling channels in the bandage or in the area between bandage and shaft or roller body, as proposed for example in DE 1 029 723 A for use in briquetting presses, would not be helpful in the described process of stripping the bandage, since it a high temperature difference between the cool shaft and the hot bandage arrives just in the area of the joint surface.
- the system of radial cooling channels which, as proposed in DE 25 36 688 A1 for a hot briquetting of one or a plurality of cooling channels in the center of the roll core to the shell or the surface of the core, is not transferable to the present problem, since the local coat is not executable because of its segmentation and its paraxial cooling holes as brusque bare bandage.
- the contrast in the document WO 2014/012770 improved, complex cooling system for a press roll with bandage is not because of its arranged in the drum cooling holes and its arranged in the roll core radial inlet and outlet channels from the center to the bandage for use in the processes of the thermal Removing or shrinking a bandage suitable.
- the object of the invention is therefore to provide a grinding roller of a high-pressure roller press, in which a simple, fast and gentle material separation of a shrunk bandage of the shaft and a simple, fast and material-friendly frictional connection of a bandage with the shaft are possible even with large shaft diameter.
- the object of the invention is also to specify a method associated with this grinding roller for separating bandage and shaft and a method for non-positive connection of bandage and shaft.
- the object of the invention is achieved by a grinding roller of a high-pressure press with the features of claim 1, by a method for separating a bandage and a shaft in such a grinding roller with the features of claim 6 and by a method for frictional connection of a bandage and a shaft solved such a grinding roller with the features of claim 7. Further advantageous embodiments are specified in the subclaims to claim 1.
- the shaft has cooling bores extending in the axial direction for the flow of coolant. These channel-like cooling bores, which pass completely through the shaft and are open at both ends for the inlet or outlet of the gaseous or liquid coolant, are thereby obtained.
- the shaft of the grinding roller is suitably mounted at high pressure roller presses at the ends, so that the shaft is only in a central region or longitudinal section of the bandage and is protected by this during the milling process against wear.
- the cooling bores are arranged in the outer region of the shaft in such a way that they pierce the interior of a geometric circular ring through the shaft at a cross section through the shaft perpendicular to the axis of rotation, in the region of the longitudinal section of the shaft with bandage casing.
- the center of this imaginary circle lies on the axis of rotation.
- the outer radius r max of the annulus is equal to the outer radius of the shaft r w
- the inner radius r min of the annulus is one third of the outer radius (1/3 r max ), preferably two thirds of the outer radius (2/3 r max ).
- cooling is best suited if it takes place by means of cooling channels within such a metered, outer region of the shaft.
- the cross-sections through the cooling holes lie entirely within this range, ie in particular not open on the surface (or outer joint surface) of the shaft.
- Such a construction enables effective cooling of the grinding roller, in particular the shaft, even in the outer region of the shaft, when the shaft diameter is a few meters (typically up to 2.5 m).
- the bandage can be profiled on its surface, so that an autogenous wear protection layer is formed on the grinding roller during the grinding process by adhesion of a layer of comminuted and compacted millbase.
- an autogenous wear protection layer is formed on the grinding roller during the grinding process by adhesion of a layer of comminuted and compacted millbase.
- additional bodies will not be considered terminologically in the present context as part of the bandage.
- their assembly or disassembly are generally separate and possibly separate from the processes described herein of stripping and mounting the bandage on the shaft.
- the cooling holes are located in the outer region of the shaft. Due to the sometimes heavy loads of the grinding roller in the grinding operations a symmetrical to the axis of rotation of the roller distribution of the cooling holes is preferable because of the forces acting.
- An embodiment of the invention therefore provides that the cooling holes in a perpendicular to the axis of rotation executed cross section through the shaft symmetrically distributed on a circle (arrangement circle) with center on the axis of rotation and radius n, between the outer and inner radius of the pierced, geometric circular ring is (r min ⁇ n ⁇ r max ), are arranged.
- the cooling holes are therefore arranged at equidistant intervals on a circle in the outer region of the shaft, the arrangement circle being engaged by the shaft surface at least far enough into the shaft interior that the cooling holes are not cut on the shaft surface, ie are open.
- the symmetrical arrangement also allows for uniform cooling of the shaft in the process of applying and removing the heated bandage.
- the cooling holes in a perpendicular to the axis of rotation executed cross section through the shaft symmetrically distributed on at least two concentric circles (arrangement circles) with center on the axis of rotation and radii (n, r 2 , ...) lying between the outer and inner radius of the pierced, geometric circular ring (r m in ⁇ n ⁇ r 2 ⁇ ... ⁇ r max ) are arranged, wherein the cooling holes of different arrangement circles in the radial direction with each other or offset from each other.
- the bores are located on an array circle centrally below or above the gap between two holes on the adjacent array circle.
- a strong and rapid cooling of the shaft is intended in its outer region for the removal and mounting of the bandage
- a strong decrease in temperature radially from the inside to the outside can have negative effects on the shaft material, for example. This can be particularly in phases in which, for example, unforeseen, delays the process of mounting the heated bandage.
- An embodiment of the invention therefore provides that centrally through the shaft a central cooling bore is provided for the flow through with gaseous or liquid coolant. If necessary, this cooling in the center of Wave are counteracted to a possibly too high temperature gradient. This can also prove to be advantageous if the shaft in turn is assembled from a plurality of concentric hollow cylinders, the non-positive connection would solve at excessive temperature gradients over long periods.
- cooling tubes for guiding the coolant are arranged in the cooling bores.
- the construction of the grinding roller according to the invention is aimed at being able to carry out simple, rapid and material-saving procedures for disassembling (pulling) or mounting (mounting) bandages on or on shafts in grinding rolls which have a large roll diameter, in particular a large shaft diameter exhibit.
- an inventive method for separating bandage and shaft is provided, which is characterized by the following steps: heating the bandage by external heat supply for thermal expansion of the bandage, thereby cooling the shaft with a cooling medium flowing through the cooling holes and pulling off the bandage in the longitudinal axis defined by the axis of rotation of the shaft.
- the bandage is to be removed from the shaft of the grinding roller according to the invention, a dilation of the bandage due to thermal expansion is effected, as is previously known, by rapid, very intensive heat input from the outside to the bandage.
- a cooling of the shaft is made so that it does not expand in terms of their outer diameter also to a relevant extent. Cooling by supplying a coolant in the center of the shaft is not sufficient for large shaft diameters.
- the construction of the grinding roller according to the invention with the characteristics of the shaft allows a simple and quickly carried out process.
- Bandage and shaft must of course be given here in a size ratio, which leads to a well-known, shrink-fit connection in the known thermal shrinking.
- the skilled person will make a suitable interference fit here, taking into account the specific thermal expansion behavior of the materials involved, so choose a bandage inside diameter, which is slightly smaller at ambient temperature than the outer diameter (joint diameter) of the shaft.
- the inventive method for non-positive connection of the bandage and the shaft is characterized by heating the separately present bandage, cooling the shaft with a coolant flowing through the cooling holes and by pulling the bandage on the shaft, wherein the wound-up bandage shrinks by cooling or cooling on the shaft ,
- the cooling of the bandage is advantageous before the process of winding and is continued during this.
- the removal of cooling by means of the present invention in the outer region, near the joining surface arranged cooling holes for only a small heat input into the shaft, so that it does not expand and the heated, thus extended bandage can be striped in the axial direction over the shaft.
- the bandage contracts and it results in a non-positive connection.
- This shrinkage can be accelerated by continuous cooling of the shaft and possibly cooling from the outside, which makes the expert so that the desired material properties are retained or adjust.
- the methods of peeling and winding can be performed in exactly the same way, when several smaller bandages are arranged side by side in the axial direction.
- Figure 1 shows the shaft of a grinding roller according to the invention in a schematic side view.
- FIG. 2 shows a cross section through the grinding roller with location of the cooling holes.
- Fig. 3 shows a cross section through the grinding roller in the embodiment with two arrangement circles.
- the shaft 1 of a grinding roller 2 according to the invention is shown in side view, as is typical for use in high-pressure roller presses (roller presses).
- the grinding roller 2 consists of the shaft 1 and a not shown here, by thermal shrinkage frictionally connected to the shaft 1, wear-resistant bandage 3.
- the shaft 1 is rotatable and rotationally symmetrical to a rotational axis 4 and tapers towards the ends in favor of Storage, the lighter weight and easier removal and mounting a bandage 3 from or on the middle, the largest diameter possessing portion of the shaft.
- 1 Schematically drawn are also two cooling holes 5, which are arranged according to the invention in the outer region of the shaft 1.
- FIG. 2 illustrates in a direction perpendicular to the axis of rotation 4 cross-section through a grinding roller 1 according to the invention in the section where the shaft 1 is enclosed by the bandage 3, schematically the geometric relationships of the position of the cooling holes 5.
- the cooling holes 5 arranged symmetrically on an imaginary arrangement circle 6.
- the cooling holes 5 do not intersect the joining surface 7 between the shaft 1 and the bandage 3, but are advantageously arranged in the outer region of the shaft 1. According to the invention, they are arranged in an imaginary, here symbolically with its inner circumference drawn circular ring 8, 8 ', the center of which lies on the axis of rotation 4 to the advantage of the method of removing and pulling the bandage 3.
- FIG. 3 shows a cross-sectional illustration (corresponding to FIG. 2) of an exemplary embodiment in which the cooling bores 5 are arranged on two imaginary concentric arrangement circles 6, 6 'with the radii n and r 2 within the imaginary circular ring 8, 8' (not shown) are.
- Several such arrangement circles 6, 6 ' may be advantageous in large milling rolls 2 for more uniform cooling without excessive perforation of the shaft 1 along only one circular line.
- the cooling bores 5 of the two arrangement circuits 6, 6 ' are offset from one another for reasons of uniform cooling.
