Definitions
- the present invention relates to grinding rollers made by casting in the technical field of the foundry. These rollers are used in vertical axis mills for the grinding of various materials including coal, cement raw material, clinker or slag.
- the invention more particularly relates to grinding rollers having inserts with higher massivity modules than those of the state of the art, possibly reinforced with agglomerates of infiltrable ceramic grains during casting.
- the application EP 1 570 905 A1 discloses a grinding roller for a vertical axis mill comprising inserts with a low massivity module ( ⁇ 2.5).
- This document highlights the various problems encountered in use with bimetallic grinding rollers comprising hard inserts made of high chromium cast iron, embedded in a ductile iron metal matrix.
- the inserts are spaced relative to each other. This space is filled with ductile iron during the casting of the grinding roller, which generates a tab blocking the inserts against each other.
- these weakly wear-resistant tabs widen, forming grooves between the inserts, which widen as one approaches the center of the grinding roller (see Fig.3). .
- each insert has on at least one of its longitudinal flanks protruding ribs so as to form a space between two inserts juxtaposed.
- preferential wear of the ductile alloy in the space is achieved, resulting in the formation of grooves between the inserts.
- the massivity module is measured by the ratio of the volume to the surface. He is designated by V / S. This value, universally used by the founders, is notably taken into account in the calculation of the masselottage of the castings because, to obtain a sound part, it is appropriate that the weight has a ratio V / S higher than that of the piece to be cast.
- V / S module depends on the choice of the length unit adopted.
- V / S a 3 / (6 to 2 ) is a / 6.
- V / S module will always be expressed in centimeters.
- the object of the present invention is to limit the disadvantages of the state of the art by minimizing the presence of grooves formed by the interstices between the inserts of a grinding roller. To reduce this number of grooves, it is necessary to increase the size and massiveness module of these inserts. With more massive inserts, the latent heat available during casting will be higher and allow easier infiltration infiltrable ceramic reinforcements thicker. In corolar, the invention therefore allows the increase of the thickness of the ceramic reinforcement of the insert. By improving the conditions of infiltration of the reinforcement by the casting metal, one can use thicker reinforcements which in turn improve the wear resistance of the assembly.
- the present invention discloses a grinding roller for mills vertical axis, made by casting in the foundry, said roller having inserts with a massivity module V / S between 3 and 5 cm, preferably between 3.2 and 4.5 cm, said inserts being embedded in a metal matrix composed of ductile iron or steel.
- the invention comprises at least one or a combination of the following features:
- the grinding roller comprises inserts with a massivity module V / S of between 3.4 and 4 cm; the inserts are arranged against each other, leaving only intermittent recesses between two inserts and allowing, during casting, to generate a dowel type connecting element improving the attachment of the insert in the metal matrix;
- the stud type connecting member has undercuts
- the inserts are not arranged parallel to the axis of rotation of said roller, but form an angle less than 45 ° with this axis;
- the inserts have a curvature along their longitudinal axis
- the inserts have an "S" shape along the longitudinal axis
- the insert comprises one or more ceramic reinforcements infiltrable by the casting metal
- said ceramic reinforcement is selected from alumina, zirconia, alumina-zirconia, metal nitrides, metal carbides and borides or mixtures thereof.
- the present invention also discloses a vertical axis mill comprising a grinding roller according to the invention.
- Figure 1 shows, according to the state of the art, a section of a vertical mill in operation and having a plurality of grinding rollers.
- Figure 2a shows a three-dimensional view of a grinding roller according to the state of the art with inserts low massivity module and spaces between the inserts.
- Figure 2b shows a three-dimensional view of an insert with low massivity module having spacing protuberances according to the state of the art.
- Figure 3 shows, with a cross-sectional view, the space remaining between two adjacent inserts according to the state of the art and the possibility of forming larger and wider grooves between the inserts at the end. as they deepen.
- FIG. 4 represents a three-dimensional view of an insert with a low massivity module with ceramic reinforcement and comprising spacers according to the state of the art.
- Figure 5 shows the comparative curves of the number of inserts in the case of inserts according to the state of the art (V / S ⁇ 2.8 cm, squares on the graph) and inserts according to the invention (V / S> 3cm, tiles on the graph).
- the number of inserts is reduced in the grinding rollers according to the invention.
- Figure 6a shows in section two inserts according to the invention arranged side by side with spacing protuberances to maintain a minimum gap between two inserts. According to the invention, the number of grooves is limited by increasing the massiveness of the insert.
- Figure 6b shows a three-dimensional view of the insert shown in Figure 6a.
- Figure 7a shows in section two inserts with ceramic reinforcement according to the invention arranged against each other with an intermittent recess.
- FIG. 7b represents a three-dimensional view of one of the two inserts of FIG.
- This recess will, during casting, to form a connection element similar to a stud with undercuts to improve the attachment of the insert in the metal matrix.
- the insert also shows the positioning of an infiltratable ceramic reinforcement by the casting metal increasing the wear resistance.
- Figures 8a and 8b illustrate the same embodiment of the invention as that of Figures 7a and 7b with however an insert bent in the direction of its longitudinal axis in the form of "S".
- This variant shaped "S" allows the groove between the inserts not to meet, during grinding, the material to be crushed frontally and at an angle less than 90 °.
- FIG. 9 represents the same roller as that of FIG. 2a but with inserts with a higher mass modulus according to the invention.
- FIG. 10a shows an insert according to the state of the art as used in a Loesche ® LM46 / 4 grinding roller and whose comparative test results are shown in Table 1.
- Figures 11a and 12a show inserts according to the invention as used in a roller Loesche ® LM46 / 4 grinder and whose test results are also shown in Table 1.
- Figures 11b and 12b represent respectively cuts according to BB.
- Figure 13a shows a three-dimensional view of an insert according to one of the preferred embodiments of the present invention.
- two of these inserts are arranged against each other leaving only an intermittent recess variable diameter in a radial direction on the grinding roller.
- the recess will allow the formation, during casting, of a stud type connecting element with undercuts.
- the insert also comprises a ceramic reinforcement infiltrable by the casting metal.
- Figure 14 shows a three-dimensional view of a variant of an insert used in the roller according to the invention wherein the recess is located on the side face in the axial direction of the insert. This recess will, during casting, generate a connecting element in the axial direction of the grinding roller.
- An infiltratable ceramic reinforcement by the casting metal is also present in this embodiment.
- Figures 15 and 16 show an embodiment of the invention in which the inserts are not positioned parallel to the axis of rotation of the grinding roller, but form an angle less than 45 ° with this axis.
- This type of arrangement has the advantage that the groove between the inserts is biased during the grinding of the material to be grinded which has the effect of less deterioration of the surface of the grinding roller and therefore a longer life of the -this.
- the connecting element will have a kind of "stud" which may include undercuts.
- ceramic reinforcement or agglomerate ceramic grains located in the insert also called “cake”, “padding” or “wafer” in English.
- the grooves between the inserts 2 of a grinding roller 1 constitute a preferential wear area which not only adversely affects the life of the grinding roller 1, but also the grinding efficiency and the quality crushed product. These grooves can also be a source of unwanted vibrations during the operation of the mill 6. The wear is further accentuated in the case of inserts reinforced by infiltrable ceramics 5 because, by being created, the groove deforce the edges of the insert 2, the optional ceramic reinforcement 5 therefore has a tendency to crumble and wear more quickly.
- the depth of infiltration depends on the latent heat available and therefore the amount of liquid metal available to achieve the infiltration.
- the quantity of metal available for a given insert volume is insufficient to correctly infiltrate a ceramic reinforcement beyond a thickness of about 50 mm.
- the infiltrable ceramic reinforcement 5 is sometimes called slab or even
- Powder "cake” or “wafer” in English and generally consists of an agglomerate of ceramic grains leaving gaps to let penetrate the casting metal. He is well known to the skilled person. In terms of composition, it is generally, without pretention to exhaustivity, oxides such as alumina, zirconia, alumina-zirconia, silica or metal nitrides, metal carbides such as carbide titanium or tungsten carbide, borides or mixtures of these various constituents.
- the massivity module of the insert is therefore directly related to the infiltration capacity of infiltrable ceramic reinforcement 5 of the insert 2 by the casting metal 4.
- the number of inserts placed on the periphery of the grinding roller 1 is generally determined empirically. by the dimension of the insert in order to obtain sufficient mechanical strength of the roller in use (see Fig. 5).
- the thickness of the ceramic reinforcement 5 is set at a value less than about 50 mm to ensure good infiltration during casting.
- the lengths of the insert 2 and the ceramic backing 5 are approximately equal to the width of the grinding roll 1.
- the width of the ceramic backing 5 is generally about the width of the insert (see Fig. 4).
- the number of inserts as a function of the outer diameter of the roller is given by the upper curve of Figure 5.
- the inserts placed in the grinding rollers have a ratio V / S between 1 and 2.8 cm (see Fig. 2a).
- the V / S ratio of the inserts must be between 3 and 5 cm, preferably between 3.2 and 4.5 cm and particularly preferably between 3.4 and 4. cm.
- Figure 13a shows an insert 2 designed according to a preferred embodiment of the invention. It has, on the lateral faces, cylindrical recesses 3 which alternate concave parts and convex parts. During the casting of the metal constituting the structure of the roller 1, the recesses 3 are filled with metal and the alternation of shape of the recess 3 can generate stud-type connecting elements with undercuts allowing a high performance fixing of inserts 2 in their metal matrix 4. They solidarisent the inserts 2 with the structure of the roller 1.
- the insert 2 generally comprises a small thickness protrusion on the lower face, thus eliminating the risk of sliding in the radial direction of the roller 1.
- This small thickness protrusion may be in particular in the form of a tail of dovetail anchoring, as illustrated in particular in Figure 11b.
- Figures 11 and 12 show solutions that differ in the thickness of the ceramic reinforcement 5 considered, given the importance of the solicitations encountered in service.
- Some corrugated shapes of the inserts shaped "S", for example, illustrated in Figures 8a and 8b, create grooves of the same shape between the inserts during wear and can soften the shock generated by this groove thanks to the progressiveness of the meeting thereof with the bed of material to grind. This reduces the risk of vibrations.
- the examples of shapes given in the present description are not limiting; other geometric shapes can of course be imagined and are part of the present invention. Examples
- the three types of inserts 2 are shown in FIGS. 10, 11 and 12.
- the inserts are cast in a type of cast iron of 3% by weight of carbon and 16% by weight of chromium (U19) and then integrated (embedded) in a grinding roller whose metal matrix consists of a spheroidal graphite cast iron type GGG40.
- the crushed material is a cement raw material.
- the inserts 2 comprise infiltratable ceramic reinforcements 5 of the alumina-zirconia type.
- the diameter of the rollers is 2000 mm in the 3 cases.
- the number of hours of service represents the service life of the rollers.
