Description

Technical Field

[0001] This utility model relates to the field of mill liner technology, and in particular to a corrugated liner for a ball mill. Background Technology

[0002] With the rapid development of society, the demand for finer and more efficient material grinding in various industries is increasing. The application scenarios of ball mills are constantly expanding, from traditional mining and cement manufacturing to emerging industries such as chemicals and ceramics. As a key piece of equipment for material grinding, the performance of ball mills plays a crucial role in production efficiency and product quality. As one of the core components of ball mills, the importance of ball mill liners cannot be underestimated.

[0003] In the early days, individual liners were fixed to the inner wall of the ball mill cylinder with a large number of bolts. During the operation of the ball mill, the undulations of the liner surface would lift the grinding media to a certain height and then drop it to impact and crush the material. Now, advanced liners have been optimized in terms of material and structural design, and more wear-resistant alloy materials are used. However, under long-term high-intensity working conditions, the wear problem of the liners is still serious, especially at the crest of the wave, which frequently rubs against the grinding media and materials, leading to accelerated wear, shorter replacement cycles, and increased equipment maintenance costs and downtime. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a corrugated liner for ball mills, which aims to improve the problem in the prior art where the crest of the wave frequently rubs against the grinding media and materials, leading to increased wear, shorter replacement cycles, and increased equipment maintenance costs and downtime.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a corrugated liner for a ball mill, comprising a base plate, a liner mechanism for grinding is provided on the top of the base plate, a shock-absorbing mechanism for damping vibration is provided on the bottom of the base plate, and an installation mechanism is provided on the bottom of the base plate.

[0006] The liner mechanism includes a fixing plate, which is fixed to the top of the base plate. A wave plate assembly is provided on the top of the fixing plate. The top of the wave plate assembly is provided with multiple hemispherical protrusions and multiple threaded holes. Replacement components are provided on the inner walls of the threaded holes.

[0007] As a further description of the above technical solution:

[0008] The damping mechanism includes a damping plate disposed at the bottom of the base plate. The inner wall of the base plate is provided with multiple fixing sleeves. The inner wall of the fixing sleeves is provided with damping components. The top of the damping components is provided with a sealing gasket.

[0009] As a further description of the above technical solution:

[0010] The wave plate assembly includes wave teeth, which are fixed to the top of the fixed plate, and the top surface of the wave teeth is provided with a guide groove.

[0011] As a further description of the above technical solution:

[0012] The replacement component includes a threaded rod, the outer wall of which is threaded to the inner wall of a threaded hole, and an impact block is fixedly connected to the top of the threaded rod.

[0013] As a further description of the above technical solution:

[0014] The shock-absorbing assembly includes a shock-absorbing spring, which is disposed on the inner wall of the fixed sleeve, and a rubber rod is disposed in the middle of the shock-absorbing spring.

[0015] As a further description of the above technical solution:

[0016] The mounting mechanism includes a bolt, which is fixed to the bottom surface of the substrate, and a nut is threaded onto the outer wall of the bolt.

[0017] As a further description of the above technical solution:

[0018] The bottom of the substrate has multiple heat dissipation grooves, and the outer wall of the bolt is provided with a washer.

[0019] As a further description of the above technical solution:

[0020] The guide groove is disposed between the troughs of the wave teeth, and the replacement component and hemispherical protrusion are disposed at the crests of the wave teeth.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the wave teeth adopt a gradual height, which, together with the grinding media of different diameters, forms a gradient impact zone, improving the grinding efficiency of the entire process from coarse to fine crushing. The guide groove guides the grinding media and the material to form a spiral motion trajectory, reducing ineffective friction and extending the movement path of the material in the cylinder. The hemispherical protrusion enhances the randomness of the collision when the grinding media falls, improving the crushing uniformity of the material. The impact block is fixed by a threaded rod and a threaded hole, and can be replaced individually after wear, reducing maintenance costs.

[0023] 2. In this utility model, the damping plate absorbs the impact energy of the grinding body, reduces vibration transmission, and lowers equipment noise. Multiple fixed sleeves form a separate unit. The rubber rod absorbs minor vibrations, while the damping spring absorbs larger vibrations and deformations, ensuring the stable operation of the liner and extending its service life. A heat dissipation groove is opened on the back of the liner, which is connected to the ventilation hole of the mill cylinder to accelerate heat dissipation and cool the liner.
