Description

Technical Field

[0001] This utility model relates to the field of anti-wear structure technology, specifically a ball mill corrugated liner. Background Technology

[0002] Ball mill liners are used to protect the mill body from direct impact and friction between the grinding media and materials. Different types of liners can also be used to adjust the movement of the grinding media to enhance their crushing effect on the materials, thereby improving the mill's grinding efficiency, increasing output, and reducing metal consumption. The crests on the ball mill liners are mainly designed to improve their ball-carrying capacity.

[0003] The existing Chinese utility model patent with publication number CN202893443U discloses a corrugated liner for a ball mill, including a support frame fixedly connected to the ball mill cylinder and a liner body fixed to the support frame and used to protect the cylinder. The corrugated liner of this utility model increases the height of the crests and the height difference between the crests and troughs, making the sliding of materials with large ball diameters smoother, reducing the wear rate between the material and the crests, maintaining the material carrying effect of the liner for a longer time, and improving the material carrying capacity. In addition, the transition between the crests and troughs is set as a smooth arc surface. At the transition points where there is no material carrying effect, the transition radius is large and the transition is smooth, which greatly reduces the concentrated stress when these protrusions are impacted by materials, making it less prone to corner chipping, thereby extending the service life of the liner.

[0004] Based on the aforementioned patent searches and in conjunction with existing equipment, it was found that the internal liner of the mill is a crucial component of the coal grinding system, and its design rationality directly affects the mill's grinding efficiency and energy consumption. By designing the liner, the mill's crushing and grinding efficiency can be improved, thereby reducing energy consumption. Traditional corrugated liners, due to their poor ball-carrying capacity, require a large number of steel balls to achieve the desired operating effect, leading to increased equipment weight, high operating current, and failure to meet energy conservation and emission reduction requirements. These problems all affect the use of the equipment. Utility Model Content

[0008] To achieve the above objectives, the present invention provides the following technical solution: a ball mill corrugated liner, comprising a basic structural component, wherein a liner side end component is installed at the upper end of the basic structural component to facilitate subsequent improvement of the efficiency inside the ball mill and reduction of wear inside the ball mill, and a liner structural component is installed on the upper left side of the liner side end component to facilitate subsequent improvement of the efficiency inside the ball mill and reduction of wear inside the ball mill.

[0009] The upper end of the liner side end assembly is provided with a second arc-shaped surface, and the right side of the second arc-shaped surface is provided with a third arc-shaped surface. The upper end of the third arc-shaped surface is provided with a grinding ball hole, which is used in conjunction with the discharge hole to facilitate the subsequent discharge of the grinding ball.

[0010] The upper end of the liner structure assembly is provided with a first arc-shaped surface A, and the right side of the first arc-shaped surface A is provided with a first arc-shaped surface B. The upper end of the first arc-shaped surface B is provided with a hole, which is installed at the upper end of the first arc-shaped surface to facilitate the subsequent discharge of grinding balls for use.

[0011] As a preferred embodiment of this utility model, a liner base is installed at the upper end of the basic structure component, and an mounting surface is installed at the lower end of the liner base. A discharge hole is installed at the upper end of the liner base, and the mounting surface is installed at the lower end of the liner base, which facilitates the subsequent installation of the upper structure into the ball mill.

[0012] As a preferred technical solution of this utility model, a first base plate is installed on the upper end of the liner side end assembly. The first base plate fixes the upper arc-shaped surface for easy subsequent use.

[0013] As a preferred technical solution of this utility model, a second base plate is installed on the upper end of the liner structure assembly. The second base plate installs the upper structure and facilitates subsequent use in conjunction with the first base plate.

[0014] As a preferred embodiment of the present invention, the liner side end assembly is installed on the upper end of the liner base in the base structure assembly, and the liner structure assembly is installed on the left side of the second arc-shaped surface in the liner side end assembly.

The first arc surface A has the same structure as the first arc surface B. The peak slope height of the first arc surface A is higher than that of the second arc surface. The hole has the same structure as the grinding ball hole.

[0018] Compared with the prior art, the present invention provides a ball mill corrugated liner with the following advantages:

[0019] 1. This utility model, through the design of the overall device, aims to maximize crushing and grinding efficiency. Based on the distribution of grinding balls within the mill, different corrugated liners are designed along the axial direction of the mill. The movement trajectory and height of the grinding balls are affected by the liner waveform. Therefore, by designing matching waveforms, the height of the grinding balls in different sections can be controlled, thereby improving the crushing and grinding effect of coal. In areas requiring higher crushing efficiency, corrugated liners with steeper or larger fluctuations can be used to carry more grinding balls and generate greater impact force. In areas requiring fine grinding, liners with gentler waveforms can be used to slow down the movement speed of the grinding balls, promote close contact between materials, and achieve precise control of the movement of grinding balls within the mill. By setting the corrugated liner structure as a structure with decreasing peak height from the middle to both sides, the traditional corrugated liner, due to its poor ball-carrying capacity, requires a large number of steel balls to achieve the desired operating effect, leading to increased equipment weight, high operating current, and failure to meet energy conservation and emission reduction requirements.

[0030] Please see Figure 1 - Figure 4The upper end of the basic structure component 1 is equipped with a liner base 101, and the lower end of the liner base 101 is equipped with a mounting surface 102. The upper end of the liner base 101 is equipped with a discharge hole 103, and the lower end of the mounting surface 102 is an arc-shaped surface. The discharge hole 103 is connected to the grinding ball hole 204.

[0031] With the above structure: the upper mounting surface 102 is installed and used by installing the liner base 101. The mounting surface 102 is installed at the lower end of the liner base 101, which facilitates the subsequent installation of the upper structure into the ball mill. The discharge hole 103 is installed at the upper end of the liner base 101, which facilitates the subsequent discharge of grinding balls to grind the material.

[0033] With the above structure: the upper arc-shaped surface is fixed by installing the first base plate 201 for easy subsequent use; the second arc-shaped surface 202 is installed on the upper end of the first base plate 201 for easy grinding of materials with grinding balls; the third arc-shaped surface 203 is installed on the right side of the second arc-shaped surface 202 to reduce contact with the grinding balls, slow down the movement speed of the grinding balls, and promote close contact between materials; the grinding ball hole 204 is used in conjunction with the discharge hole 103 to facilitate the subsequent discharge of the grinding balls.

In areas requiring fine grinding, a second arc surface 202 and a third arc surface 203 with gentler waveforms can be used to slow down the movement speed of the grinding balls, promote close contact between materials, and achieve precise control of the movement of the grinding balls inside the mill. A first bottom plate 201 and a second bottom plate 301 are installed at the upper end of the liner base 101.
