Definitions
- the invention relates to a grinding roller for the high-pressure crushing granular material to be ground, comprising a reinforcement with hard bodies, which protrude from the surface of the main body of the grinding roller.
- These hard bodies do not serve primarily as a shell for the surface of the main body of the grinding roller, but for structuring the surface, which accumulates in the spaces between the hard bodies, the material to be crushed on the surface of the main body of the grinding roller. As a result, forms on the surface of the body of the grinding roller, a layer of the material to be crushed itself, which protects the grinding roller from schlndender stress.
- the counter rotating grinding rollers run at the same, opposite speed and, if possible, without relative slip, in order to avoid unnecessary and undesired abrasion of the hard bodies protruding from the surface of the main body of the grinding roller and not to continuously remove the layer of material to be comminuted.
- This type of wear protection is also called 'autogenous wear protection', because the wear protection layer consists of the material to be shredded itself.
- Another aspect in the reinforcement of grinding rollers with hard bodies is the solubility of the hard bodies from the surface of the body of the Mahlwal- Zen. Because even with autogenous wear protection, the grinding roller gradually takes damage by abrasive wear. As a result, the surface of the main body of the grinding rollers is no longer ideal cylindrical shaped. As a result, the gap width and the nip pressure can no longer optimally be controlled in a roller press, as a result of which the comminution performance of the relevant roller press is reduced.
- the surface of the grinding roller is usually completely renewed.
- the hard body is removed from the surface, the grinding roller is turned off by machining, so that it is shaped again ideal cylindrical, and the receiving holes for the hard body in the surface of the grinding roller are correspondingly deepened so that new or still usable, used hard body can be used can.
- the refurbishment of a grinding mill for high pressure crushing is quite labor intensive, this type of refurbishment is still economical because the cost of the mill roll and hard body material is very high.
- the surface of the main body of the grinding roller can not be turned in the presence of hard body to a cylindrical format, it is necessary to remove the hard body before.
- the removal of all hard body of a grinding roller is very complex because they are firmly anchored on the one hand in the main body of the grinding roller and because the hard body in addition by the stress in the high pressure crushing in the material of the grinding roller are driven and also because a grinding roller has 50,000 or more individual hard body.
- German Laid-Open Application DE 10 2006 010 042 A1 proposes for the easier removal of the hard bodies to provide the hard bodies with a central recess into which a tool is intended to engage for removal.
- a rather elongated shape for the hard body is proposed in the latter published patent application and corresponding to the elongated shape, the recess is narrow in relation to the diameter of the hard body.
- these elongated hard bodies with a narrow cutout are clogged with the material to be comminuted in a costly, removable form and also that the cutout is too narrow to wedge a strong and robust tool for removal therein.
- the tool size in question allows for removal, under the harsh conditions under which the hard bodies are replaced, a corresponding tool is too sensitive for continuous use.
- DE 10 2008 014 809 A1 proposes to pierce the grinding roller from the side in a lathe and to remove the entire surface with the hard metal bodies below the lower end of the hard body in the main body of the grinding roller.
- This method is in principle carried out in the installed state of the roller press at the site of the roller press itself, but this type of workup costs an undesirably large amount of material which also reduces the diameter of the grinding roller, which is finally also detrimental to the grinding performance.
- the object of the invention is therefore to provide a grinding roller for the high-pressure comminution granular material, which with less wall allows the removal of the hard body from the surface of the body.
- the object of the invention is achieved in that at least a portion of the profile body having a continuous recess, wherein the recess extends in the radial direction of the grinding roller and wherein the ratio of the height to the width of the hard body 1, 5 or less.
- the invention proposes that the hard body having a continuous recess, wherein the recess extends in the radial direction of the grinding roller.
- the hard bodies are not elongated, but have in relation to the diameter of a cylindrical shell shape of the hard body to a height, measured in the radial direction in the inserted into the surface of a grinding roller state, which exceeds the above defined diameter at most by 1, 5.
- the hard body according to the invention is thus shallower than the hitherto known hard body for reinforcing the surface of grinding rollers and allows a larger diameter in relation to the diameter of the through recess, so that a much stronger tool in relation to the hard body dimension can be used to the hard body from the surface of the body of the grinding roller to remove.
- the ratio of the diameter of the recess to the diameter of the hard body is variable even with elongated hard bodies, but only at the expense of the remaining wall thickness, which is too small in elongated hard bodies and breaks in use.
- the hard bodies according to the invention are introduced into the surface of the grinding roller in such a way that they are pushed onto a stud bolt arranged centrally in a blind bore, which supports the wall between the recess and the outer circumference.
- the stud bolt consists optionally from the material of the surface of the grinding roller itself, because the stud bolt was left standing when introducing a circular bore in the surface of the body of the grinding roller, or it is possible to centrally insert a stud of a further material in the center of the bore and on the Postpone hard body.
- the recess should be at least partially filled in order to prevent the material of the autogenous wear layer from collecting and settling at the bottom of the blind bore, but also and in order to protect the hard body from deformation movement, which eventually ends up in fracture of the hard body in the surface of the grinding roller ends.
- the hard body according to the invention has the advantage that it is easier to remove through the prepared recess, because in the hard body of solid material, it is only possible with great effort to introduce a hole to approach a tool.
- the grinding roller is turned to a cylindrical size and the holes for the hard body in the surface of the body of the grinding roller are deepened corresponding to the Abtragungstiefe the surface of the body of the grinding roller and new or still operational, used hard body with the continuous Recess are used again in the surface.
- the hard body as the main main profile have the shape of a general cylinder with bore, preferably as an essential main profile of the form either the shape of a hollow circular cylinder or a hollow prism or a hollow cylinder with elliptical base.
- a general cylinder is understood to mean any base surface that can be displaced along the perpendicular to the plane Surface plane is driven to a three-dimensional body.
- the edges thus formed can be chamfered with a chamfer and it is also possible that the edges are rounded or bear beads.
- the shape of the cylinder as an essential main profile, it depends on the essential envelope shape as an essential main profile, which surrounds the hard body. If the edges of the hard body are not chamfered or rounded, then beads or applied edges as a secondary profile can also pierce a substantial envelope shape as the main profile.
- convex shapes are contemplated, such as a circle, an ellipse, a square, a rectangle, a pentagon or hexagon, or generally polygonal, regular or not regular, symmetric or asymmetrical, but also concavo-convex, like a cross, a star, a T-shape, an H-shape, all shapes regular or irregular, symmetric or asymmetrical.
- the hard bodies are shaped like a slate general cylinder as an essential main profile, wherein the base surface is shaped as that of the general cylinder, but the cylinder is brought as a main main profile by shearing in an oblique shape. Due to the shape of an oblique general cylinder, the hard bodies can be given a preferred direction when seated in the surface of the main body of the grinding roller in order to promote the formation of a wear protection layer.
- the continuous recess may have a substantially circular profile, substantially elliptical profile or substantially polygonal profile in cross-section, or substantially have a shape described above for the base of the general cylinder , As secondary profile come round or pointed bulges facing inwards or outwards or chamfers or bulges at the edges of the continuous recess.
- the cross section of the continuous recess may be symmetrical or asymmetrical, regularly shaped or irregularly shaped.

- FIG. 1 shows a top view of the surface 5 of a grinding roller 1 according to the invention with an autogenous wear protection layer of regrind 40, in the surface 5 of which hard bodies 10 are embedded.
- Hard body 10 have a continuous recess 20 which extends in the embedded state of the hard body 10 substantially in the radial direction of the grinding roller 1, while the height h of the hard body in the radial direction in the inserted state in the surface of the hard body is not higher than that of the first , 5 times the diameter or the width b of a cylindrical envelope of the hard body.
- the hard bodies 10 have the shape of a general oblique cylinder and thus show a preferred direction upon rotation of the grinding roller 1, the orientation of the through recess 20 strictly radial or by the extent of the tilted shape of the oblique general cylinder from the radial direction of the grinding roller. 1 differ.
- the spaces between the hard bodies 10 sam- Melted during the operation of the grinding rollers 1 in a high-pressure roller press to be comminuted material 40, which forms an autogenous wear protection layer.
- the autogenous wear protection layer at the edge of the grinding roller 1 is usually thinner and looser than in the middle, where the
- Main Kompaktzone present in the nip of the corresponding roller press The different density and layer thickness are shown in Figure 1 by a different intense puncturing.
- the continuous recess 20 is at least partially filled in the operation of the grinding roller 1 with a positive-locking body 30, so that no regrind 40 collects in the through-hole 20, there solidified and so when pulling the hard body 10 requires an increased workload to release.
- the positive-locking body supports the wall between the continuous recess 20 and the circumference in front of an undesirable deformation movement of the hard body 10 which is to be broken during operation of the roller press.
- This way of releasing a hard body 10 in its blind hole offers itself for glued-in hard bodies 10. After a hard body 10 has been broken by twisting in its blind bore 50, this can be relatively easily removed from the blind bore 50.
- FIG. 2 shows a single hard body 10 according to one embodiment of the invention of the grinding roller 1 from FIG.
- a main profile to recognize a cylindrical shape of the hard body 10 wherein the main profile by a bevel 15 deviates as a side profile of the shell shape of an ideal cylinder.
- the height h of the hard body in the radial direction in the state of the hard body inserted into the surface is not higher than 1.5 times the diameter or the width b of a cylindrical envelope of the hard body 10.
- Hard body 10 is centered with a continuous cylindrical recess 20 traversed, which is at least partially filled in the embedded state of the hard body 10 with a positive-locking body 30, to prevent ground material 40 collects in the through-hole 20 and solidified there and also to protect the hard body 10 from undesirable deformation movement, which can lead to the breakage of the hard body 10.
- the main profile of the hard body 10 deviates through a dome-shaped or hemispherical round bottom 16, wherein the through-cut recess 20 penetrates the hemispherical cattle floor in the middle.
- the continuous recess 20 has as a secondary profile two bulges 45, through which the through-hole deviates from an ideal cylindrical shape. In addition to bulges and hexagonal recesses, square recesses, cross or slot recesses come into consideration, thereby making the hard body 10 for a torsion tool tangible.
- FIG. 3 shows two arbitrary examples of the cross section of a hard body 10, these examples being in star form and being only a few examples of a multitude of possible cross-sectional profiles as a polygonal shape.
- Cross-sectional profiles 60 as a star-shaped cross-sectional profile and cross-sectional profile 70 as a substantially T-shaped profile form two examples of a multiplicity of different cross-sectional profiles, the hard body corresponding to the cross-sectional profile 60 being, for example, the envelope of an oblique general Cylinder, which is shown in a perspective view in sub-figure 61, and whose shell shape is identical to the shape of the hard body.
- the shell shape of the hard body with the cross-sectional profile 70 which has round bulges at the edges, which do not extend over the entire cross-section of the general oblique cylinder, a side profile, which pierces the main profile.
- the main profile shown in subfigure 75 is in the form of an oblique general cylinder with a T-shaped base.

- the individual states (100a, 100b, 100c, 100d, 100e, 100f, 100g) each represent a radial section of a grinding roller 1, wherein the radial section runs centrally through the hard body 10. It can be clearly seen from the hatching of the main body of the grinding roller 1 that the material of the surface 5 of the grinding roller 1 fills the hard body 10 in its recess by a form-fitting body 30.
- the positive-locking body 30, which may also consist of the material of the surface 5 of the grinding roller 1 itself, is bored out of the hard body 10, represented by the states 100a-100b, which indicate the respective state before and after the boring represent and a tool which wedges in the recess 20 is used to remove the hard body 10 from the surface 5 of the grinding roller 1, represented by the pre and Nachzurent 100b-100c. Thereafter, the surface 5 is freed from the hard bodies 10 and the worn profile of the surface 5 of the grinding roller 1 comes to light, state 100c.
- the blind bore 50 in which the hard body 10 is embedded, corresponding to the removal of the surface 5 of the grinding roller 1 recessed, before and after state 100d-100e and a hard body 10th , new or used, is inserted into the surface 5 in the recessed blind bore 50, which by the sectional drawings as state 100e before insertion of the hard body 10 and the
- Sectional drawing is shown as state 10Of.
- the continuous recess 20 of the hard body 10 is filled again with a form-fitting body 30.
- the positive-locking body 30 may be a stud bolt which is screwed in at the bottom of the blind bore 50, or the positive-locking body 30 is driven into the continuous recess 20 of the hard body 10.
- the steps according to the method thus result: removal (100a-100b) of any material present in the continuous recess of the hard body 10, pulling out (100b-100c) of the hard body 10 with a tool which the hard body 10 is wedged in the continuous recess 20 or the hard body 10 engages therein, restoring (100c-100d) the shape of the main body of the grinding roller 1 by machining, wherein the main body of the grinding roller 1 is slightly reduced, possibly deepening (100d-100e) the bores in which the hard bodies 10 are seated, inserting (100e-100f) new or still usable, used hard bodies 10, and finally filling (100f-100g) of the through-hole 20 with a positive-fit body 30.
