Description

Technical Field

[0001] The utility model relates to the field of ball mill lining plates, in particular to a wear-resistant lining plate for a ball mill. Background Art

[0002] Ball mill is the key equipment for crushing materials after they are broken. It is suitable for grinding various ores and other materials, and is widely used in mineral processing, building materials and chemical industries. Ball mill is composed of a horizontal cylinder, a hollow shaft for inlet and outlet, and a grinding head. The cylinder is a long cylinder with grinding bodies inside. The cylinder is made of steel plates. The grinding bodies are generally steel balls and are loaded into the cylinder according to different diameters and a certain proportion. In order to protect the cylinder, a liner needs to be installed in the cylinder of the ball mill to prevent the cylinder from being directly impacted and rubbed by the grinding medium and materials. The liner is divided into manganese steel liner and rubber liner. Compared with manganese steel liner, rubber liner has better wear resistance, so rubber liner is widely used.

[0003] However, there are some shortcomings in the current liners. When multiple liners are installed, lifting plates are placed between the liners. There is no positioning device when the lifting plate is initially spliced ​​with the liner, so the lifting plate is prone to displacement. When the lifting plate and the liner are fixed inside the ball mill with fasteners, the position of the lifting plate needs to be adjusted again, which is troublesome. Utility Model Content

[0004] The main purpose of the utility model is to provide a wear-resistant lining plate for a ball mill, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A wear-resistant liner for a ball mill comprises a liner body, a lifting plate and an insert plate. The lifting plate is provided on one side of the liner body, and the insert plates are movably embedded on both side surfaces of the liner body near the front end and the rear end.

[0007] Preferably, storage grooves are provided on both side surfaces of the lining body near the front end and the rear end.

[0008] Preferably, a T-shaped groove is provided on the lower surface of the lifting plate, slots are provided on both side surfaces of the lifting plate near the front end and the rear end, and embedding grooves are provided on the inner lower surface of the T-shaped groove and on both sides near the front end and the rear end, and the embedding grooves are connected to the slots.

[0009] Preferably, a reinforcement frame is fixedly mounted on the surface of the plug board, and limiting sliders are fixedly mounted on both sides of the rear end of the reinforcement frame.

[0010] Preferably, the plug board is embedded in the storage groove, and the front end of the plug board passes through the slot and is embedded in the embedding groove.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, by arranging the lining plate body, the lifting plate and the plug plate to cooperate with each other, when the lifting plate is spliced ​​with the lining plate body, the plug plates on both sides of the lining plate body are inserted into the slots of the lifting plate, so that the spliced ​​lining plate body and the lifting plate can be positioned to avoid misalignment of the lifting plate and the lining plate body. During the subsequent installation, the installation process will not be inconvenienced due to the misalignment of the lifting plate and the lining plate body. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-4 The wear-resistant liner for a ball mill shown in the figure comprises a liner body 1, a lifting plate 2 and an inserting plate 3. The lifting plate 2 is provided on one side of the liner body 1, and the inserting plates 3 are movably embedded on both side surfaces of the liner body 1 near the front end and the rear end.

[0020] Storage grooves 101 are provided on both side surfaces of the lining plate body 1 and near the front and rear ends, and the storage grooves 101 can store the plugging plate 3 when not in use; T-slots 202 are provided on the lower surface of the lifting plate 2, and slots 201 are provided on both side surfaces of the lifting plate 2 and near the front and rear ends, and embedding grooves 203 are provided on the inner lower surface of the T-slots 202 and near both sides of the front and rear ends, and the embedding grooves 203 are connected with the slots 201; a reinforcement frame 301 is fixedly sleeved on the surface of the plugging plate 3, and limiting sliders 302 are fixedly installed on the two side surfaces of the rear end of the reinforcement frame 301, and the limiting sliders 302 can prevent the plugging plate 3 from being completely pulled out of the storage groove 101; the plugging plate 3 is embedded in the storage groove 101, and the front end of the plugging plate 3 passes through the slot 201 and is embedded in the embedding groove 203, and there is a certain friction between the plugging plate 3 and the slot 201.

[0021] It should be noted that the utility model is a wear-resistant lining for a ball mill. When in use, when the lifting plate 2 is spliced ​​with the lining body 1, the plug plates 3 on both sides of the lining body 1 are inserted into the slots 201 of the lifting plate 2, so that the lining body 1 and the lifting plate 2 after splicing can be positioned to avoid misalignment of the lifting plate 2 and the lining body 1. During subsequent installation, the installation process will not be inconvenienced by the misalignment of the lifting plate 2 and the lining body 1. In the subsequent installation process, the upper end of the fastener will be embedded in the T-slot 202 of the lifting plate 2, and then the lower end of the fastener will pass through the inner wall of the ball mill. Finally, the fastener will be fixed with a nut, and the fastener can be pressed on the plug plate 3. In this way, the fixed fastener can maintain the external force of pressing the plug plate 3, thereby making the connection between the lining body 1 and the lifting plate 2 more secure.
