Description

Technical Field

[0001] This disclosure relates to crushing equipment for crushing rocks, ores, or the like. More specifically, this disclosure relates to a so-called vertical shaft impact crusher comprising one or more wear-resistant plates. Background Technology

[0002] Vertical shaft impact crushers, which have a rotor rotating about a vertical axis, can be used when crushing rocks, ores, cement clinker, and other materials. The rotor may include a frame comprising an upper plate, a lower plate, and multiple wall members extending between the upper and lower plates. The material to be crushed is fed through an opening centrally arranged in the upper plate of the rotor. One or more outlets are located between the upper and lower plates. A distributor plate is arranged on the upper surface of the lower plate of the rotor. As the material to be crushed impacts the rotating distributor plate, the material is dragged generally radially outward through one or more outlets and impacts external crushing surfaces, which typically include the accumulation of material to be crushed formed on the inner surface of the self-crushing crushing chamber. This self-crushing has proven to ensure high-quality shaped particles, such as aggregates. The rotor also includes multiple wear-resistant components that protect the rotor. Many of these are called rotor tips or cavity wear plates. Rotor tips are often arranged at the exit of the corresponding outlet of the rotor. Typically, these components experience the greatest wear and tear. However, in current rotors, the wear-resistant components are attached to the rotor using fasteners (i.e., bolts, etc.), which often suffer excessive wear and tear. Furthermore, replacing the wear-resistant plates usually requires partial disassembly of the rotor, and sometimes removal of surrounding equipment within the crusher, to allow for the removal of the wear-resistant components.

[0003] To address this issue, WO 2013 / 140049 A1 proposes a rotor having segmented wear plates with channels extending between the upper and lower surfaces of the wear plates. Once the wear plates are positioned in the rotor, mounting rods are positioned within the channels, extending between the upper and lower plates of the rotor, thereby attaching the segmented wear plates to the rotor. A problem with the solution disclosed in WO2013 / 140049A1 is the need for top-down access to the rotor to guide the mounting rods through the upper plate before entering the channels within the wear plates. Therefore, there is a need in the art for a faster and easier process when replacing wear plates worn to their limit, and also for providing environmentally friendly wear plates. Summary of the Invention

[0004] One objective is to mitigate, alleviate, or eliminate one or more of the aforementioned deficiencies and disadvantages in the prior art, either alone or in any combination, and to at least address the aforementioned problems.

[0005] According to a first aspect, a wear-resistant plate is provided for a rotor of a crushing device. The rotor includes a frame comprising an upper plate, a lower plate, and a plurality of wall members extending longitudinally between the upper and lower plates. The wear-resistant plate can be arranged adjacent to at least one wall member and / or another wear-resistant plate, and extends longitudinally between the upper and lower plates. The wear-resistant plate includes:

[0006] A first body extending along a first general direction and having an upper surface, a lower surface, and a first adjacent surface extending at least partially between the upper and lower surfaces of the first body, and

[0007] The second body extends along a second overall direction different from the first body's first overall direction, and has an upper surface, a lower surface, and a second adjacent surface extending at least partially between the upper and lower surfaces of the second body.

[0008] The first and second adjacent surfaces of the wear-resistant plate are configured to be adjacent to the corresponding first and second surfaces of the rotor, so as to form a self-locking mechanism due to rotational force during use.

[0009] This wear plate may be advantageous because it provides boltless installation of the wear plate within the rotor. The wear plate is designed to abut against the first and second surfaces of the rotor to provide a wear plate that is held in position within the rotor during operation by a self-locking mechanism formed by rotational forces. Therefore, no additional fastening devices are required. It should be understood that the corresponding surface of the rotor can be a surface of the rotor frame itself, such as the surface of the upper plate, lower plate, or wall member. It should also be understood that the corresponding surface of the rotor can be the surface of another wear plate disposed within the rotor. Therefore, the rotor can include more than one wear plate (multiple wear plates), or even more than one type of wear plate can be applied. The wear plate can be configured to abut against the surface of the rotor itself and / or the surface of another wear member disposed within the rotor. However, other components may be present in the rotor that can be abutted against by the wear plate, thus forming part of the self-locking mechanism.

[0010] In the disclosed wear-resistant plate design, the first and second bodies extend along different general directions, providing a self-locking mechanism in the respective directions, which in turn helps to hold the wear-resistant plate in place in the corresponding direction. In other words, the adjacent surfaces of the wear-resistant plates are angled relative to each other and therefore extend along different directions. The corresponding surfaces of the rotor are also angled relative to each other and therefore also extend along different directions. Preferably, the adjacent surfaces of the wear-resistant plates extend along a direction substantially parallel to the corresponding surface of the rotor that the wear-resistant plate should abut. Through this design of the wear-resistant plate in relation to the rotor surface, a self-locking mechanism can be formed due to rotational force, and boltless installation can be achieved.

[0011] Here, the term "extending at least partially between the upper and lower plates" means that at least a portion of the abutment surface of the wear-resistant plate abuts the corresponding surface of the rotor. Therefore, the wear-resistant plate does not necessarily abut the corresponding surface of the rotor along the entire distance between the upper and lower plates of the rotor.

[0012] Wear plates are preferably arranged in the exposed areas of the rotor. Here, the term "exposed area" refers to any area of ​​the rotor exposed to wear during rotor operation. Therefore, wear plates are typically exposed to significant wear during their service life. It may be advantageous to have wear plates that can be installed in the rotor without requiring any fixing devices, as this facilitates quick, easy, and user-friendly replacement of wear plates worn to their limit. Furthermore, boltless installation of the wear plates ensures that only a limited number of devices are needed when replacing worn wear plates. This also facilitates quick, easy, and user-friendly replacement of worn wear plates. Moreover, the ease with which wear plates can be replaced when worn to their limit means less time is required, which in turn reduces production downtime.

[0013] Therefore, the wear plate is superior to existing technologies, allowing for boltless installation of the wear plate in the rotor. This, in turn, facilitates quick, easy, and user-friendly replacement of wear plates worn to their limit, resulting in a safer design from a maintenance and installation perspective, as well as reduced production downtime.

[0014] According to some embodiments, the wear plate also includes a third body extending along a third general direction different from the first general direction of the first body, and having an upper surface, a lower surface, and a third abutting surface extending at least partially between the upper and lower surfaces of the third body, wherein the wear plate is configured to abut the third surface of the rotor so as to serve as part of a self-locking mechanism formed due to rotational force in use.

[0015] This is advantageous because the wear-resistant plate can also abut a third surface of the rotor in addition to the first and second surfaces, thus allowing for further improvement of the self-locking mechanism formed by rotational forces. Improved stability of the wear-resistant plate is achieved during rotor operation through the multiple surfaces adjacent to the rotor.

[0016] According to some embodiments, at least one of the first, second, and third surfaces of the rotor is arranged radially outside the first, second, and third adjacent surfaces of the wear-resistant plate.

[0017] This is advantageous because by arranging the rotor surface radially outside at least one adjacent surface, the wear plate remains in place radially when the rotor is in use. In other words, in the preferred embodiment, at least one surface of the rotor is always arranged radially outside the corresponding adjacent surface of the wear plate to form a self-locking mechanism in the radial direction due to rotational force.

[0018] According to some embodiments, the upper and lower surfaces of the corresponding body are flat surfaces.

[0019] This is advantageous because it allows for quick and easy installation and removal of the wear-resistant plates in the rotor between the upper and lower plates. In other words, having flat surfaces allows the wear-resistant plates to be slidably arranged in the rotor, especially if the inner surfaces of the upper and lower plates are also flat.

[0020] According to some embodiments, the wear-resistant plate also includes a groove extending between the upper and lower surfaces, the groove being configured to receive a tip of a hard material (such as a metal or ceramic material or similar material), wherein the tip of the hard material has a greater hardness than the wear-resistant plate.

[0021] This is advantageous because it allows the insertion of a tip of hard material with a greater hardness than the rest of the abrasion plate. Typically, the tip of the hard material is positioned on the portion of the abrasion plate exposed to maximum wear and tear. In a preferred embodiment, the tip of the hard material is made of metal. Furthermore, the tip of the hard material can be replaced when it wears out, even though the rest of the abrasion plate is not worn. Therefore, the tip and groove of the hard material can be advantageous because they can increase the lifespan of the abrasion plate, which can result in a more environmentally friendly abrasion plate overall.

[0022] According to some embodiments, a first abutting surface abuts a first surface of the rotor to hold the wear plate in place in the radial direction, and a second abutting surface abuts a second surface of the rotor to hold the wear plate in place in the circumferential direction.

[0023] This is advantageous because it allows the wear plate to remain in place in both the radial and circumferential directions due to the rotational force generated during use. The arrangement of the corresponding body of the wear plate, in relation to the arrangement of the corresponding surfaces of the rotor, ensures that the wear plate remains in place due to the rotational force.

[0024] According to some embodiments, the third abutment surface is adjacent to the third surface of the rotor in order to hold the wear plate in place in the radial and / or circumferential directions.

[0025] This is advantageous because it allows for an improved self-locking mechanism that forms the wear plate due to rotational force. Therefore, the more the wear plate remains in position during use (i.e., during rotor rotation), the better its retaining (fixing) performance.

[0026] According to some embodiments, the wear-resistant plate is segmented in the longitudinal direction.

[0027] This is advantageous because it allows the wear plate to be formed from more than one component. By forming the wear plate from more than one component, each component can have a reduced weight compared to the weight of the entire wear plate. This allows for lighter lifting, resulting in a safer design from a maintenance and installation perspective. Furthermore, since each wear plate component is smaller than the entire wear plate, it can be installed or removed through the service door of the crushing equipment. Therefore, the wear plate can be replaced without disassembling the crusher equipment and / or rotor.

[0028] This is further advantageous because it allows for the formation of segmented wear plates that will be boltless and mounted relative to each other using different wear plate components. Therefore, the rotational force causes the respective wear plate components to form a self-locking mechanism relative to the corresponding surfaces of the rotor.

[0029] Typically, wear plates wear unevenly along their contours. Segmented wear plates allow for the replacement of only worn components rather than the entire plate. This ability to replace only worn components results in more environmentally friendly wear plates. Furthermore, the uneven wear along the contours of the wear plate means that segmented design allows wear plate components to be repositioned rather than replaced. This increases the overall lifespan of the wear plate.

[0030] According to some embodiments, the wear-resistant plate includes at least a first member, a second member, and a third member arranged sequentially along the longitudinal direction.

[0031] According to some embodiments, the first component and the third component can be interchanged.

[0032] This is advantageous because it allows each wear plate component to be worn to its limit along its entire contour. Typically, the first and third components are worn in opposite directions, which allows them to be interchanged so that they wear evenly along their complete contour. Furthermore, when the upper and lower surfaces are flat, it also allows for easy swapping.

[0033] According to some embodiments, the wear-resistant plate includes at least a first member, a second member, a third member, and a fourth member arranged sequentially along the longitudinal direction. According to some embodiments, the first member and the third member can be interchanged, and the second member and the fourth member can also be interchanged.

[0034] According to some embodiments, the wear-resistant plate is the rotor tip.

[0035] According to some embodiments, the wear plate is a tip carrier wear plate.

[0036] According to some embodiments, the wear-resistant plate is a cavity wear-resistant plate.

[0037] According to a second aspect, a rotor for a crushing device is provided, comprising:

[0038] The frame includes an upper plate, a lower plate, and a plurality of wall members extending longitudinally between the upper and lower plates, and

[0039] A wear-resistant plate, which can be arranged adjacent to at least one wall member and / or another wear-resistant plate, and extends longitudinally between the upper plate and the lower plate, the wear-resistant plate comprising:

[0040] A first body extending along a first general direction and having an upper surface, a lower surface, and a first adjacent surface extending at least partially between the upper and lower surfaces of the first body, and

[0041] The second body extends along a second overall direction different from the first body's first overall direction, and has an upper surface, a lower surface, and a second adjacent surface extending at least partially between the upper and lower surfaces of the second body.

[0042] The wear-resistant plate is configured to be adjacent to the first and second surfaces of the rotor so as to form a self-locking mechanism due to rotational force during use.

[0043] According to some embodiments, the wear-resistant plate also includes a third body extending along a third general direction different from the first general direction of the first body, and having an upper surface, a lower surface, and a third abutting surface extending at least partially between the upper and lower surfaces of the third body, wherein the wear-resistant plate is configured to abut the third surface of the rotor so as to serve as part of a self-locking mechanism formed due to rotational force during use.

[0044] According to a third aspect, a crushing or grinding apparatus for crushing or grinding hard materials is provided, the crushing apparatus comprising:

[0045] A rotor having a frame including an upper plate, a lower plate, and a plurality of wall members extending longitudinally between the upper plate and the lower plate, and

[0046] A wear-resistant plate, which can be arranged adjacent to at least one and / or another wear-resistant plate of the plurality of wall members, and extends longitudinally between the upper plate and the lower plate, the wear-resistant plate comprising:

[0047] A first body extends along a first general direction and has an upper surface, a lower surface, and a first adjacent surface extending at least partially between the upper and lower surfaces of the first body.

[0048] The second body extends along a second overall direction different from the first body's first overall direction, and has an upper surface, a lower surface, and a second adjacent surface extending at least partially between the upper and lower surfaces of the second body.

[0049] The first and second adjacent surfaces of the wear-resistant plate are configured to be adjacent to the first and second surfaces of the rotor, so as to form a self-locking mechanism due to rotational force during use.

[0050] The effects and features of the second and third aspects are largely similar to those described above in conjunction with the first aspect.

[0061] The present disclosure will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the disclosure are illustrated. However, the present disclosure can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the disclosure to those skilled in the art.

[0062] Figure 1The example illustrates a crushing device 100 for crushing or grinding rocks, ores, cement clinker, and other hard materials. The crushing device 100 is configured to crush materials by impact. The crushing device 100 may be a vertical shaft impact crusher.

[0063] The crushing device 100 includes a top 102 and a chamber 104. The chamber 104 is disposed on the base 106 of the crushing device 100. The top 102 is disposed on the top of the chamber 104. The crushing device 100 also includes a feed opening 110. The feed opening 110 is disposed within the top 102. The feed opening 110 can be configured to receive material to be crushed and feed the material into the chamber 104. The crushing device 100 also includes a rotor 108. The rotor 108 is disposed within the chamber 104. The rotor 108 is configured to accelerate the material received in the chamber 104 toward a crushing surface. Therefore, the rotor is the main working component of the crushing device 100. Figures 2-3 Rotor 108 will be discussed further.

[0064] In addition, the crushing equipment 100 may also include a service door 112.

[0065] Reference Figure 2 The rotor 108 is shown in more detail. The rotor includes a frame 202. The frame 202 includes an upper plate 204, a lower plate 206, and a wall member 208. The wall member 208 extends longitudinally L between the upper plate 204 and the lower plate 206. The rotor 108 also includes an inlet opening 210 and an outlet 212. The inlet opening 210 is arranged in the upper plate 204. The outlet 212 is located between the upper plate 204 and the lower plate 206. The rotor 108 may include more than one outlet 212. During operation of the crushing apparatus 100, the rotor 108 is configured to rotate about a rotation axis A. The rotation axis A is a vertical axis generally parallel to the longitudinal direction L. The rotor 108 preferably rotates counterclockwise about the rotation axis A. The rotor 108 also includes a distributor plate 214. When the material to be crushed impacts the rotating distributor plate 214, the material will be dragged generally radially outward through the outlet 212 and impact the inner surface of the chamber in which the rotor 108 is positioned.

[0066] Rotor 108 also includes wear-resistant plates 500, 600, and 700. Wear-resistant plates 500, 600, and 700 can extend longitudinally L between the upper plate 204 and the lower plate 206 of rotor 108. Wear-resistant plates 500, 600, and 700 are preferably arranged in exposed areas of the rotor. In other words, wear-resistant plates 500, 600, and 700 can be arranged in any area of ​​rotor 108 exposed to wear during operation. Figure 3 Figure 7 further discusses the wear-resistant plate.

[0067] Reference Figure 3 and Figure 4 The interior of rotor 108 is shown by way of example. Building upon the discussion above, wear plates 500, 600, and 700 may be arranged adjacent to at least one wall member 208 of rotor 108. Wear plates 500, 600, and 700 may also be arranged adjacent to another wear member 500, 600, or 700 arranged in rotor 108.

[0068] When the rotor 108 is in operation, wear-resistant plates 500, 600, and 700 may abut against the first and second surfaces of the rotor 108, thereby forming a self-locking mechanism due to rotational force. The surfaces of the rotor 108 that the wear-resistant plates 500, 600, and 700 may abut against are typically one or more of the following: at least one wall member 208; and / or another wear-resistant plate 500, 600, or 700 arranged adjacent to the wear-resistant plates 500, 600, and 700 when installed in the rotor 108. The wear-resistant plates 500, 600, and 700 may also abut against a third surface of the rotor 108, further improving the self-locking mechanism due to rotational force.

[0069] In a preferred embodiment, at least one of the first, second, and third surfaces of the rotor 108 is arranged radially outward of at least a portion of the wear plates 500, 600, and 700, such that the wear plates 500, 600, and 700 can be held in place in the radial direction RD by rotational force.

[0070] Referring to Figures 5-7, different embodiments of wear-resistant plates 500, 600, and 700 are shown by way of example. Wear-resistant plates 500, 600, and 700 include first bodies 501, 601, and 701. The first bodies 501, 601, and 701 extend along a first general direction GD501, GD601, and GD701. The first bodies 501, 601, and 701 have upper surfaces 501a, 601a, and 701a and lower surfaces 501b, 601b, and 701b. The first bodies 501, 601, and 701 have first adjacent surfaces 511, 611, and 711. The first adjacent surfaces 511, 611, 711 extend at least partially between the upper surfaces 501a, 601a, 701a and the lower surfaces 501b, 601b, 701a of the first bodies 501, 601, 701, and in some embodiments may extend continuously between the upper surfaces 501a, 601a, 701a and the lower surfaces 501b, 601b, 701a of the first bodies 501, 601, 701. The wear-resistant members 500, 600, 700 also include second bodies 502, 602, 702. The second bodies 502, 602, 702 extend along a second general direction GD502, GD602, GD702. The second bodies 502, 602, 702 have upper surfaces 502a, 602a, 702a and lower surfaces 502b, 602b, 702b. The second bodies 502, 602, and 702 have second adjacent surfaces 512, 612, and 712. The second adjacent surfaces 512, 612, and 712 extend at least partially between the upper surfaces 502a, 602a, and 702a and the lower surfaces 502b, 602b, and 702b of the second bodies 502, 602, and 702, and in some embodiments may extend continuously between the upper surfaces 502a, 602a, and 702a and the lower surfaces 502b, 602b, and 702b of the second bodies 502, 602, and 702.

[0071] Wear-resistant components 500, 600, and 700 may further include third bodies 503, 603, and 703. The third bodies 503, 603, and 703 extend along a third general direction GD503, GD603, and GD703. The third bodies 503, 603, and 703 have upper surfaces 503a, 603a, and 703a and lower surfaces 503b, 603b, and 703b. The third bodies 503, 603, and 703 also have third adjacent surfaces 513, 613, and 713. The third adjacent surfaces 513, 613, 713 extend at least partially between the upper surfaces 503a, 603a, 703a and the lower surfaces 503b, 603b, 703a of the third bodies 503, 603, 703, and in some embodiments may extend continuously between the upper surfaces 503a, 603a, 703a and the lower surfaces 503b, 603b, 703a of the third bodies 503, 603, 703.

[0072] Hereinafter, the wear-resistant plate 500 of the first embodiment will be referred to as the first wear-resistant plate 500. The wear-resistant plate 600 of the second embodiment will be referred to as the second wear-resistant plate 600. The wear-resistant plate 700 of the third embodiment will be referred to as the third wear-resistant plate 700. (See also...) Figures 5a-5b The first wear-resistant plate 500 is shown in further detail. (Refer to...) Figures 6a-6c The second wear-resistant plate 600 is shown in further detail. (Refer to...) Figures 7a-7b The third wear-resistant plate is shown in further detail.

[0073] As in Figure 4 As best shown, the first wear plate 500 is positioned on the exit side of the outlet 212, facing the outlet 212. As material is dragged outward through the outlet 212, some material may impact the first wear plate 500, which may undergo significant abrasion and tearing during operation of the crushing equipment 100. The first wear plate 500 may be the tip of the rotor. Typically, these wear plates experience the greatest abrasion and tearing compared to the wear plates arranged in the rotor 108.

[0074] A first wear-resistant plate 500 is arranged adjacent to a third wear-resistant plate 700. The third wear-resistant plate 700 includes a first surface of the rotor 108, and the wall member 208a includes a second surface of the rotor 108. When the rotor 108 is in operation, the first wear-resistant plate 500 abuts against the third wear-resistant plate 700 and the wall member 208a, such that a self-locking mechanism is formed due to rotational force during rotation. A first abutting surface 511 of the first wear-resistant plate 500 abuts against the surface of the third wear-resistant plate 700. This holds the first wear-resistant plate 500 in place in the radial direction RD. A second abutting surface 512 of the first wear-resistant plate 500 abuts against the wall member 208a. This holds the first wear-resistant plate 500 in place in the circumferential direction CD.

[0075] The first wear-resistant plate 500 is also arranged adjacent to the outer surface of the third wear-resistant plate 700, which includes the third surface of the rotor 108. When the rotor 108 is rotating, the first wear-resistant plate 500 can abut the third wear-resistant plate 700, thereby further forming a self-locking mechanism due to rotational force. The third abutment surface 513 of the wear-resistant plate 500 abuts the outer surface of the third wear-resistant plate 700. This allows the first wear-resistant plate 500 to remain in place in the direction CD. The arrangement of the second abutment surface 512 and the third abutment surface 513 of the wear-resistant plate 500 ensures that the wear-resistant plate 500 does not dislodge in the circumferential direction of the rotor 108.

[0076] As the rotor rotates counterclockwise, the second wear plate 600 is positioned just upstream of the outlet 212, with the wall member 208c positioned between the second wear plate 600 and the outlet 212. The second wear plate 600 is positioned adjacent to the side of the wall member 208c, that is, opposite to the side of the wall member 208c facing the outlet 212. As material is dragged outward through the outlet 212, some material may impact the second wear plate 600. The second wear plate 600 is sometimes referred to as a cavity wear plate.

[0077] The second wear-resistant plate 600 is arranged adjacent to two wall members 208b and 208c, which include a first surface and a second surface of the rotor 108. When the rotor 108 rotates, the second wear-resistant plate 600 can abut against the corresponding wall members 208b and 208c, thereby forming a self-locking mechanism due to rotational force. The first abutting surface 611 of the second wear-resistant plate 600 abuts against the wall member 208b. This allows the second wear-resistant plate 600 to remain in place in the radial direction RD. The second abutting surface 612 of the second wear-resistant plate 600 abuts against the surface of the wall member 208c. This allows the wear-resistant plate 600 to remain in place in the circumferential direction CD.

[0078] The second wear-resistant plate 600 can be arranged adjacent to another wall member 208, which serves as the third surface of the rotor 108. When the rotor 108 rotates, the second wear-resistant plate 600 can abut against this other wall member 208, further creating a self-locking mechanism due to rotational force. A third abutting surface 613 is located at the heel-shaped third body 603 of the second wear-resistant plate 600. This heel-shaped third body 603 extends through a corresponding opening in the wall member 208c and abuts the inner surface of the opening in the wall member 208c. This allows the second wear-resistant plate 600 to remain in place in direction CD. Thus, similar to the first wear-resistant plate 500, a reliable self-locking mechanism is generated during the rotation of the rotor 108 by applying three abutting surfaces in three different directions to hold the second wear-resistant plate 600 in place.

[0079] The third wear plate 700 is positioned radially outside the first wear plate 500. As material is dragged outward through outlet 212, some material may impact the third wear plate 700. The third wear plate 700 is sometimes referred to as the tip bracket wear plate.

[0080] The third wear-resistant plate 700 is arranged adjacent to the wall member 208d, which includes a first surface, a second surface, and a third surface of the rotor 108. Here, the first surface of the wall member 208d faces radially inward towards the rotor 108, and the second and third surfaces are side surfaces of the wall member 208d that are generally perpendicular to the first surface. When the rotor 108 rotates, the third wear-resistant plate 700 abuts against the first, second, and third surfaces of the wall member 208d, thereby forming a self-locking mechanism due to rotational force. The first abutting surface 711 of the third wear-resistant plate 700 abuts against the radially inward first side of the wall member 208d. This keeps the third wear-resistant plate 700 in place in the radial direction RD. The second and third abutting surfaces 712 and 713 of the third wear-resistant plate 700 abut against the side surfaces of the wall member 208d. This keeps the third wear-resistant plate 700 in place in the circumferential direction CD.

[0081] The third wear-resistant plate 700 is also arranged adjacent to the first wear-resistant plate 500. When the rotor 108 is running, the third wear-resistant plate 700 can be adjacent to the first wear-resistant plate 500, thereby further forming a self-locking mechanism due to the rotational force. Therefore, the interaction between the first wear-resistant plate 500, the third wear-resistant plate 700 and the wall member 208d keeps the wear-resistant plates 500 and 700 in place in the circumferential direction CD and the radial direction RD.

[0082] Referring back to Figures 5-7, the upper and lower surfaces of the corresponding bodies of wear-resistant plates 500, 600, and 700 are flat surfaces.

[0083] Wear-resistant plates 500, 600, and 700 may further include grooves 510, 610, and 710. Grooves 510, 610, and 710 may extend between the upper and lower surfaces of the wear-resistant plates 500, 600, and 700. Grooves 510, 610, and 710 are configured to receive tips 520, 620, and 720 of hard metal. Preferably, the tips 520, 620, and 720 of the metal have a greater hardness than the wear-resistant plates 500, 600, and 700.

[0084] Furthermore, wear-resistant plates 500, 600, and 700 can be segmented wear-resistant plates. The wear-resistant plate may include: first components 500a, 600a, and 700a; second components 500b, 600b, and 700b; and third components 500c, 600c, and 700c. These components can be arranged sequentially along the longitudinal direction L. Wear-resistant components 500 and 700 may include fourth components 500d and 700d, which are arranged along the longitudinal direction L after the third components 500c and 700c. Preferably, the first components 500a, 600a, and 700a and the third components 500c, 600c, and 700c can have similar or identical designs. This allows the first components 500a, 600a, and 700a and the third components 500c, 600c, and 700c to be interchangeable.

[0085] Preferably, the second components 500b and 700b and the fourth components 500d and 700d can have similar designs. This allows the second components 500b and 700b and the fourth components 500d and 700d to be interchanged.

[0086] Therefore, it should be understood that the purpose of this disclosure is to reduce the problem of replacing worn wear plates in rotor 108 by providing boltless installation of wear-resistant components. This is achieved due to the design of the wear plate relative to a specific surface of rotor 108, which, when installed in rotor 108, will abut against that specific surface. This creates a self-locking mechanism due to rotational force. Another objective is to provide a more environmentally friendly wear plate. Moreover, since wear plates 500, 600, and 700 can be segmented wear plates, it should also be understood that the purpose of this disclosure is to enable the installation or removal of segmented wear plates through service door 112 of crushing equipment 100. Therefore, wear plates 500, 600, and 700 can be replaced without disassembling crushing equipment 100 and / or rotor 108.

[0087] Those skilled in the art will recognize that the present invention is by no means limited to the preferred embodiments described above. Rather, many modifications and variations can be made within the scope of the appended claims. Furthermore, in practicing the claimed invention, those skilled in the art can understand and implement variations to the disclosed embodiments from a study of the drawings, the disclosure, and the appended claims.
