Description

Technical Field

[0001] This utility model relates to the field of cone crusher technology, specifically a cone liner that can reduce the proportion of fine materials. Background Technology

[0002] In the field of material crushing and processing in industries such as mining, metallurgy, and construction, cone crushers are widely used due to their high crushing capacity. Among them, the cone liner is a core vulnerable component of the crusher, which directly affects the crushing efficiency, finished product particle size distribution, and equipment service life.

[0003] Currently, traditional cone liners have significant limitations in structural design. Their overall structural form is relatively fixed, and their surface morphology and working mode lack necessary flexibility. The liner surface is usually a single smooth structure, or only has fixed-specification, non-adjustable protrusions or grooves for crushing. This fixed design results in a single interaction between the material and the liner during crushing operations, with a fixed crushing path, making it difficult to achieve differentiated crushing treatment based on different material characteristics and production needs.

[0004] Specifically, the aforementioned structural defects directly lead to an unreasonable particle size distribution in the finished product. In actual production, there is often a situation where the proportion of fine-sized materials (e.g., 0-5mm) is too high, while the output of target particle size materials (e.g., 10-20mm) is insufficient. This is mainly because traditional cone liners lack adjustable crushing paths and adaptable screening spaces, making it difficult to precisely control the degree of material crushing within the crushing chamber. When it is necessary to adjust the output proportion of different particle sizes to meet diverse production tasks, existing liners cannot provide effective adjustment methods, resulting in the particle size distribution of the finished product remaining relatively fixed and difficult to flexibly adjust according to actual production needs.

[0005] This limitation severely restricts the adaptability and flexibility of cone crushers in handling diverse production tasks, failing to meet the requirements of modern industrial production for fine and differentiated material particle size. This not only affects the efficiency of subsequent processing stages but also reduces the overall economic efficiency of the production process. Therefore, to address the aforementioned problems with traditional cone liners, there is an urgent need to develop a new liner structure that enables adjustable crushing paths and controllable particle size distribution to overcome the shortcomings of existing technologies. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a conical liner that can reduce the proportion of fine materials, and its purpose is to solve the problems in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a conical liner plate that can reduce the proportion of fine materials, comprising: a fixed conical liner plate and a movable conical liner plate; the inner surface of the fixed conical liner plate and the outer surface of the movable conical liner plate are provided with a plurality of trapezoidal grooves, and the trapezoidal grooves adopt an outward draft angle design.

[0008] Furthermore, the inner surface of the fixed cone liner is provided with a plurality of first trapezoidal grooves arranged equidistantly around it; the first trapezoidal grooves adopt an outward draft angle design; the thickness of the first trapezoidal grooves is set to be within 30%-40% of the fixed cone liner.

[0009] Furthermore, the outer surface of the moving cone liner is provided with a plurality of second trapezoidal grooves arranged equidistantly around it; the second trapezoidal grooves adopt an outward draft angle design; the thickness of the second trapezoidal grooves is set to be within 30%-40% of the moving cone liner.

[0010] Furthermore, the fixed cone liner is provided with a first glue inlet; the moving cone liner is provided with a second glue inlet.

[0011] Furthermore, the fixed cone liner is provided with support feet.

[0012] Furthermore, a welding ring is provided on the top of the moving cone liner.

[0013] Compared with existing technologies, this utility model has the following advantages: By setting trapezoidal grooves on the inner surface of the fixed cone liner and the outer surface of the moving cone liner, this utility model can effectively adjust the material ratio, especially in reducing the proportion of fine materials by 0-5mm and increasing it by 10-20mm; by using trapezoidal grooves that are narrower at the top and wider at the bottom, smooth material discharge can be ensured and material blockage can be avoided; the trapezoidal groove adopts an outward-inclined draft angle design, which makes it less likely for materials to accumulate and block during the crushing process, ensuring continuous and stable crushing, and allowing the material to be subjected to more reasonable force during the crushing process, avoiding over-crushing.
