Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, and in particular to a ball milling device for powder metallurgy. Background Technology

[0002] A ball mill is a commonly used grinding device for refining or mixing bulk metals used in metallurgy. It mainly consists of a container and a set of abrasive particles (usually steel balls). In the ball mill, the material is placed in the container, and then the container begins to rotate. The rotational motion causes the abrasive particles to collide and rub against the material, generating force and energy, which gradually reduces the particle size. This process can be used to refine, mix, or synthesize materials, enabling the powder to reach the required fineness for powder metallurgy operations.

[0003] In the existing ball mill equipment industry, the existing ball mill system process generally involves feeding materials into a ball mill for grinding, then feeding them into a mixer for further mixing, and finally feeding them into a casting system where a vacuum is first applied before casting. This process is inefficient and inconvenient to use.

[0004] An existing patent (publication number: CN201978793U) discloses a ball mill, comprising a barrel-shaped ball mill body, with a feed inlet at the top and a discharge outlet at the bottom. Couplings for connecting a drive unit are respectively provided at both ends of the ball mill body. The drive unit is mounted on a frame for fixing the ball mill body. The ball mill body also includes a pressure control device and a pressure detection device. One end of the pressure control device extends into the ball mill body to control the pressure inside the ball mill, and the other end is connected to the pressure detection device. During operation, the pressure control device and pressure detection device allow for simultaneous material mixing and ball milling while a vacuum is being created, improving work efficiency.

[0005] To address the aforementioned issues, existing patents offer a solution: the ball mill is used by simply fixing the ball mill body with a frame, so the ball mill is driven purely by a drive unit. However, a single motor is insufficient for the heavy ball mill. Utility Model Content

[0006] The purpose of this utility model is to provide a ball milling device for powder metallurgy, which can solve the problem that the existing ball milling device for powder metallurgy only uses a frame to fix the ball mill body, so the ball mill is driven purely by a drive device, and the power of a single motor is insufficient for the bulky ball mill.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a ball milling device for powder metallurgy, comprising a base, a ball milling assembly disposed on the top of the base, and friction reduction assemblies disposed on both sides of the ball milling assembly;

[0008] The ball mill assembly includes a fixed frame, a ball mill barrel, a feed gate, a toothed belt, a power motor, a pulley, and a discharge hole. Two fixed frames are disposed on the top of the base, and the ball mill barrel is rotatably connected between the two fixed frames. The feed gate is bolted to one side of the ball mill barrel, the toothed belt is engaged with the outside of the ball mill barrel, the power motor is disposed on the top of the base, the pulley is bolted to the output shaft of the power motor, the pulley is engaged with one end of the toothed belt, and the discharge hole is opened on the outside of the ball mill barrel.

[0009] Furthermore, the friction reduction assembly includes a rotary bearing and a dust cover. The two rotary bearings are respectively disposed on both sides of the ball mill barrel, the dust cover is disposed on one side of the fixed frame, and the outer ring of the rotary bearing is fixed inside the fixed frame.

[0010] Furthermore, the base has a horizontal chassis at its bottom, and several reinforcing plates are welded to the outer sides of the base and chassis. The chassis is made of 316 stainless steel.

[0011] Furthermore, the top of the fixing frame is threaded with two lifting rings, which are located on one side of the ball mill barrel. The lifting rings are made of 316 stainless steel and are used to lift the ball mill equipment.

[0012] Furthermore, a support plate is provided on one side of the ball mill barrel, the support plate has a triangular cross-section, and multiple support plates are arranged in a circumferential array on one side of the ball mill barrel.

[0013] Furthermore, a triangular plate is provided on one side of the base and chassis, and the triangular plate is located below the ball mill barrel.

[0014] Furthermore, a mounting plate is provided at the bottom of the chassis, and mounting holes are provided at the four corners of the mounting plate.

[0015] Furthermore, a vertical plate is provided on the top of the mounting plate, and a support wheel is provided on the top of the vertical plate, with the top of the support wheel located at the bottom of the ball mill barrel.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This application incorporates a ball mill assembly, which can grind smelted metals into tiny particles. The slow rotation via belt drive reduces power requirements and allows for increased grinding time, resulting in finer grinding and improved efficiency of powder metal grinding.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution:

[0026] A ball milling device for powder metallurgy includes a base 1, a ball milling assembly 2 is disposed on the top of the base 1, and friction reduction assemblies 3 are disposed on both sides of the ball milling assembly 2.

[0027] The ball mill assembly 2 includes a fixed frame 201, a ball mill barrel 202, a feed gate 203, a toothed belt 204, a power motor 205, a pulley 207, and a discharge hole 206. The two fixed frames 201 are located on the top of the base 1. The ball mill barrel 202 is rotatably connected between the two fixed frames 201. The feed gate 203 is bolted to one side of the ball mill barrel 202. The toothed belt 204 is engaged with the outside of the ball mill barrel 202. The power motor 205 is located on the top of the base 1. The pulley 207 is bolted to the output shaft of the power motor 205 and is engaged with one end of the toothed belt 204. The discharge hole 206 is located on the outside of the ball mill barrel 202.

[0028] Through the above technical solution, by setting up a fixed frame 201, a ball mill 202, a feed gate 203, a toothed belt 204, a power motor 205, a pulley 207, and a discharge hole 206, during powder metallurgy grinding, the feed gate 203 is opened to put the smelted metal and steel balls into the ball mill 202. After the power motor 205 is connected to the external power supply, the power motor 205 causes the pulley 207 to rotate, which in turn causes the toothed belt 204 to rotate. The toothed belt 204 meshes with the teeth on the outside of the ball mill 202, causing the ball mill 202 to rotate slowly on the fixed frame 201. At this time, the steel balls and smelted metal placed in the ball mill 202 are ground. When the smelted metal is ground to a diameter smaller than the discharge hole 206, that is, less than 1 mm in diameter, the smelted metal is discharged from the ball mill 202 through the discharge hole 206. At this time, the grinding process of the smelted metal is completed, and the power requirements are not high.

[0029] like Figure 4 As shown, the friction reduction assembly 3 includes a rotary bearing 301 and a dust cover 302. Two rotary bearings 301 are respectively disposed on both sides of the grinding barrel 202, and the dust cover 302 is disposed on one side of the fixed frame 201. The outer ring of the rotary bearing 301 is fixed inside the fixed frame 201. The rotary bearing 301 reduces friction between the grinding barrel 202 and the fixed frame 201, and the dust cover 302 seals the gap between the grinding barrel 202 and the fixed frame 201.

[0030] like Figure 1 As shown, a base plate 4 is provided at the bottom of the base 1, and a reinforcing plate 5 is welded to the outer side of the base 1 and the base plate 4. The base plate 4 is made of 316 stainless steel. The base plate 4 supports the base 1, increasing the distance between the ball mill barrel 202 and the ground. The reinforcing plate 5 reinforces the connection between the base plate 4 and the base 1.

[0031] like Figure 1 As shown, the top of the mounting bracket 201 is threaded with two lifting rings 6, which are located on one side of the ball mill barrel 202. The lifting rings 6 are made of 316 stainless steel. The lifting rings 6 facilitate the hoisting and movement of the mounting bracket 201.

[0032] like Figure 2 As shown, a support plate 7 is provided on one side of the ball mill barrel 202. The cross-section of the support plate 7 is triangular, and multiple support plates 7 are arranged in a circumferential array on one side of the ball mill barrel 202. By supporting the side of the ball mill barrel 202 with the support plate 7, the side of the ball mill barrel 202 can be strengthened.

[0033] like Figure 2As shown, a triangular plate 8 is provided on one side of the base 1 and the chassis 4, and the triangular plate 8 is located below the ball mill barrel 202. By setting the triangular plate 8, the inner side of the base 1 and the chassis 4 can be supported to prevent the base 1 and the chassis 4 from deforming inward.

[0034] like Figure 1 As shown, a mounting plate 9 is provided at the bottom of the chassis 4, and mounting holes 10 are provided at the four corners of the mounting plate 9. By setting bolts through the mounting holes 10, the mounting plate 9 can be fixed to the ground with reserved screw holes.

[0035] like Figure 2 As shown, a vertical plate 11 is provided on the top of the mounting plate 9, and a support wheel 12 is provided on the top of the vertical plate 11. The top of the support wheel 12 is located at the bottom of the ball mill barrel 202. The vertical plate 11 supports the support wheel 12, and the support wheel 12 supports the ball mill barrel 202.

[0036] Working Principle: In use, during powder metallurgy grinding, the feed door 203 is opened to allow smelting metal and steel balls to be placed inside the grinding barrel 202. After the power motor 205 is connected to an external power source, it causes the pulley 207 to rotate, which in turn causes the toothed belt 204 to rotate. The toothed belt 204 engages with the teeth on the outside of the grinding barrel 202, causing it to rotate slowly on the fixed frame 201. The rotary bearing 301 reduces friction between the grinding barrel 202 and the fixed frame 201, and the dust cover 302 seals the gap between them. The steel balls and smelting metal inside the grinding barrel 202 are then ground. When the smelting metal is ground to a diameter smaller than the discharge hole 206... That is, a diameter less than 1mm. At this time, the smelted metal is discharged from the ball mill barrel 202 through the discharge hole 206. At this time, the grinding process of smelting metal is completed and the power requirement is not high. The base 1 is supported by the chassis 4, which increases the distance between the ball mill barrel 202 and the ground. The chassis 4 and the base 1 are reinforced by the reinforcing plate 5. The fixed frame 201 can be easily lifted and moved by the lifting ring 6. The side of the ball mill barrel 202 is supported by the support plate 7, which can strengthen the side of the ball mill barrel 202. The inner side of the base 1 and the chassis 4 is supported by the triangular plate 8 to prevent the base 1 and the chassis 4 from deforming inward. The chassis 4 can be fixed to the ground with the reserved screw hole by the bolt passing through the mounting hole 10 and the mounting plate 9.
