Description

Technical Field

[0001] This utility model belongs to the technical field of cone crusher liner plates, specifically relating to a composite liner plate for cone crushers with pins used in the aggregate industry. Background Technology

[0002] Construction aggregate is an indispensable basic material in the construction industry. In recent years, with the rapid development of my country's infrastructure industry, the demand for construction aggregate has gradually increased. For aggregate manufacturers, aggregate crushing is an important part of the production process, and cone crushers are important processing equipment for construction aggregate.

[0003] The main working area of ​​a cone crusher is its crushing chamber, which consists of a moving cone and a fixed cone. When the crusher is running, the aggregate ore passes through the crushing chamber. Inside the crushing chamber, the moving cone liner undergoes a swaying motion. At this time, the material will squeeze and impact the cone crusher liner. The moving cone liner and the fixed cone liner are prone to wear, which leads to insufficient service life. This greatly increases the consumption of the liner, and replacing the liner will also consume a lot of time, thus reducing the working efficiency of the crusher. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a composite liner plate for cone crushers in the aggregate industry, which solves the problem mentioned in the background art that the liners of cone crushers are prone to wear, which increases the consumption of liners and reduces the working efficiency of the crusher.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a composite liner plate for a cone crusher in the aggregate industry, comprising a fixed cone liner plate, a moving cone liner plate, and pins A, B, C, and D. The fixed cone liner plate is disposed above the interior of the crusher, and the moving cone liner plate is disposed below the fixed cone liner plate inside the crusher. The inner cavity of the fixed cone liner plate and the outer wall of the moving cone liner plate cooperate to form a crushing chamber. The aggregate is crushed by the squeezing and impact of the moving cone liner plate and the fixed cone liner plate in the crushing chamber. Pins A and B are arranged in the high wear area of ​​the fixed cone liner plate, and pins C and D are arranged in the high wear area of ​​the moving cone liner plate.

[0006] The fixed cone liner is cylindrical in shape, with a stepped upper end and a gradually increasing lower end. The high wear area of ​​the fixed cone liner, namely the middle and lower part of its inner cavity, is provided with studs A and B.

[0007] The moving cone liner is generally flared, with the lower end tapering into a straight cylinder. The high wear areas of the moving cone liner, namely the middle, lower and bottom of its outer wall, are provided with studs C and D.

[0008] The cross-sections of the studs A, B, C, and D are all hexagonal, forming an overall conical structure with one end larger than the other. The larger end of studs A, B, C, and D is the mounting end, and the smaller end is the working end. The mounting ends of studs A and B are embedded in the inner wall of the fixed cone liner, and the working ends of studs A and B are flush with the inner wall of the fixed cone liner. The mounting ends of studs C and D are embedded in the outer wall of the moving cone liner, and the working ends of studs C and D are flush with the outer wall of the moving cone liner.

[0009] The stud A has a size of 20*60 and is distributed in a multi-layered ring array on the inner wall of the middle part of the fixed cone liner, with 90 studs in each layer. The stud B has a size of 20*80 and is distributed in a multi-layered ring array on the inner wall of the lower part of the fixed cone liner, with 100 studs in each layer.

[0010] The stud C has a size of 20*50 and is distributed in a multi-layered ring array on the outer wall of the middle and bottom of the moving cone liner. Each layer in the middle has 80 studs and each layer at the bottom has 100 studs. The stud D has a size of 20*70 and is distributed in a multi-layered ring array on the outer wall of the lower part of the moving cone liner. Each layer has 100 studs.

[0011] The base material of the fixed cone liner and the moving cone liner is high manganese steel, which forms a hardened layer on the surface under high impact conditions, effectively improving the performance of the liner.

[0012] The base material of the studs A, B, C and D is titanium carbide, which has a higher hardness than the base material of the fixed cone liner and the moving cone liner. It is used to share the impact of materials. The structure with the installation end inside and the working end on the surface is used to prevent the studs from falling off during operation.

[0013] The beneficial effects of this utility model are: by optimizing the structure of the crushing chamber, large pieces of material can pass through without causing material blockage; high manganese steel is selected to improve the service life of the liner, which will form surface hardening under impact environment, thus improving the wear resistance of the liner; hard alloy studs are densely and evenly distributed in the high wear area of ​​the liner, which share the impact and wear of the material with the base during operation, thus extending the service life of the liner by 30%.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figures 1-3A composite liner plate for a cone crusher used in the aggregate industry includes a fixed cone liner plate 1, a moving cone liner plate 2, and pins A3, B4, C5, and D6. The fixed cone liner plate 1 is located at the top inside the crusher, and the moving cone liner plate 2 is located below the fixed cone liner plate 1 inside the crusher. The inner cavity of the fixed cone liner plate 1 and the outer wall of the moving cone liner plate 2 cooperate to form a crushing chamber. The cone portion rotates around a fixed point under the drive of an eccentric sleeve, causing the moving cone liner plate 2 to alternately move closer to and further away from the fixed cone liner plate 1. The aggregate is subjected to the squeezing and impact of the moving cone liner plate 2 and the fixed cone liner plate 1 in the crushing chamber, thereby achieving crushing. Pins A3 and B4 are arranged in the high wear area of ​​the fixed cone liner plate 1, and pins C5 and D6 are arranged in the high wear area of ​​the moving cone liner plate 2. The fixed cone liner 1 is generally cylindrical, with a stepped upper end and a gradually increasing lower end diameter. The cylindrical fixed cone liner 1 allows large pieces of material to pass through smoothly without clogging. The high wear area of ​​the fixed cone liner 1, namely the middle and lower part of its inner cavity, is provided with studs A3 and B4. The moving cone liner 2 is generally flared, with a straight cylindrical lower end. The high wear area of ​​the moving cone liner 2, namely the middle, lower and bottom of its outer wall, is provided with studs C5 and D6. The cross-sections of the studs A3, B4, C5, and D6 are all hexagonal, forming an overall conical structure with one end larger than the other. The larger end of studs A3, B4, C5, and D6 is the mounting end 7, and the smaller end is the working end 8. The mounting ends 7 of studs A3 and B4 are embedded in the inner wall of the fixed cone liner 1, and the working ends 8 of studs A3 and B4 are flush with the inner wall of the fixed cone liner 1. The mounting ends 7 of studs C5 and D6 are embedded in the outer wall of the moving cone liner 2, and the working ends 8 of studs C5 and D6 are flush with the outer wall of the moving cone liner 2. The studs A3, measuring 20*60 mm, are arranged in a multi-layered circular array on the inner wall of the middle section of the fixed cone liner 1, with 90 studs per layer. The studs B4, measuring 20*80 mm, are arranged in a multi-layered circular array on the inner wall of the lower section of the fixed cone liner 1, with 100 studs per layer. The studs C5, measuring 20*50 mm, are arranged in a multi-layered circular array on the outer wall of the middle and bottom sections of the moving cone liner 2, with 80 studs per layer in the middle section and 100 studs per layer at the bottom. The studs D6, measuring 20*70 mm, are arranged in a multi-layered circular array on the outer wall of the lower section of the moving cone liner 2, with 100 studs per layer. The base material of both the fixed cone liner 1 and the moving cone liner 2 is high-manganese steel, which forms a hardened layer on its surface under high impact conditions, effectively improving the liner performance. The base material of the studs A3, B4, C5 and D6 is titanium carbide, which has a higher hardness than the base material of the fixed cone liner 1 and the moving cone liner 2. It is used to share the impact of materials. The structure with the mounting end 7 inside the liner and the working end 8 on the surface is used to prevent the studs from falling off during operation.

[0020] When using this utility model:

[0021] To improve the working efficiency of the cone liners, the fixed cone liner 1 of this cone crusher is cylindrical with a stepped upper end and a gradually increasing lower diameter. The moving cone liner 2 is generally funnel-shaped with a tapered lower end. The cylindrical fixed cone liner 1 allows large pieces of material to pass through smoothly without clogging. As the material moves from top to bottom, the crushing chamber space gradually decreases, thus achieving a crushing effect. The lower end of the liner bears a large impact from the material. The thickness of both the fixed cone liner 1 and the moving cone liner 2 gradually increases from top to bottom to ensure sufficient thickness in the high-wear area throughout the liner's service life. The middle and lower ends of the cone crusher liners wear faster. The tapered lower end of the moving cone liner 2 and the increased lower diameter of the fixed cone liner 1 effectively prevent cracking and damage to the edge areas of the liners due to prolonged impact during later operation.

[0022] To extend the service life of cone crusher liners, high manganese steel is used as the base material for the liner. Under high impact conditions, a hardened layer will form on the surface of the high manganese steel, which can effectively improve the performance of the liner. Hard alloy studs are densely and evenly distributed in the high wear areas of the liner. The hardness of the studs is higher than that of the base material. During operation, they share the impact and wear of the material with the base material, which extends the service life of the liner by 50%.

[0023] The stud base material is titanium carbide, and the shape is a hexagonal pyramid structure. The installation end is located inside the liner plate, and the working end is on the surface. This can effectively prevent the stud from falling off during operation. The contact surface of the hexagonal pyramid is more evenly distributed inside the liner plate, and the force-bearing area is larger. During processing, the working end of the stud is glued to the steel mesh with inorganic high temperature adhesive. This method fixes the studs densely on the steel mesh. During molding, after the cavity coating is applied, the steel mesh with studs is fixed to the cavity wall, and the outer ring is also fixed with steel mesh. After the mold is closed, the studs are suspended in the cavity and both ends are fixed with steel mesh. When molten steel is poured into the cavity, the studs will be wrapped by the molten steel. The hexagonal studs have a larger contact area with the molten steel and can better bond with the manganese steel base. The solidified finished product is a composite liner plate with cast studs. The studs are fixed with adhesive to make the surface of the stud area easier to clean after the mold is opened and to avoid unevenness of the stud working surface.

[0024] Pins C5 and D6 are arranged in the high-wear area of ​​the moving cone liner 2 substrate; pins A3 and B4 are arranged in the high-wear area of ​​the fixed cone liner 1 substrate. The pins are densely and evenly distributed to slow down the wear rate of the substrate. Generally, the length of the pins is 50-60% of the wall thickness at that location. To ensure the structural strength of the substrate and the stability of the pins, the length should not exceed 80% of the substrate wall thickness. The arrangement density and length of the pins can be adjusted and optimized later according to the on-site operation of the liner. Therefore, this utility model adopts the above-described pin composite cone liner design. The pin composite design combined with cavity optimization can greatly save costs and effectively improve the service life of the cone crusher liner.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0026] The parts of this utility model not described in detail are existing technologies.
