Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically to a rolling bearing ball mill device. Background Technology

[0002] Ball mills are key equipment for further pulverizing materials after they have been crushed. This type of grinding mill uses a certain number of steel balls as grinding media inside its cylinder. It is widely used in the production of cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal ore beneficiation, and glass and ceramics.

[0003] Currently, when using ball mills to grind crushed stone, some crushed stone is too large, and grinding it directly will affect the grinding effect, resulting in coarse particles in the finished product, which will affect the product quality. At the same time, a lot of dust will be generated during the feeding process, and the dust can easily be scattered and affect the surrounding environment. To address this, we have proposed a rolling bearing ball mill device. Utility Model Content

[0004] The purpose of this invention is to provide a rolling bearing ball mill device to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rolling bearing ball mill device, comprising a ball mill body, a feed box fixedly connected to the feed inlet of the ball mill body, a fixed plate fixedly connected to the bottom of the feed box, a motor mounted on the top of the fixed plate, a cam fixedly connected to the output end of the motor, a movable rod slidably connected inside the feed box, a fixed plate fixedly connected to the front end of the movable rod, a U-shaped plate fixedly connected to the other end of the movable rod, a spring sleeved on the surface of the movable rod, one end of the spring fixedly connected to a fixed block on the rear side of the movable rod, and the other end of the spring fixedly connected to the inner wall of the feed box, an inclined plate fixedly connected inside the feed box, a support plate fixedly connected inside the feed box, the top of the support plate slidably connected to the U-shaped plate, a fixed piece fixedly connected to the inner wall on the rear side of the feed inlet, several stone crushing cones fixedly connected to the opposite side of the fixed piece and the U-shaped plate, a dust suction mechanism provided on the left side of the feed box, and several horizontal plates fixedly connected inside the feed box.

[0006] Preferably, the dust collection mechanism includes a collection box, a suction pump is connected to the right side of the collection box, a dust collection pipe is connected to the top of the collection box, and the other end of the dust collection pipe is connected to the inside of the feed box.

[0007] Preferably, the collection box has a collection compartment inside, and the surface of the collection compartment has a handle.

[0008] Preferably, sliders are fixedly connected to both the left and right sides of the top of the U-shaped plate, and a groove is provided at the bottom of the inclined plate to cooperate with the sliders.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 As shown, the rolling bearing ball mill device includes a ball mill body 1. A feed box 2 is fixedly connected to the feed inlet of the ball mill body 1. A fixed plate 5 is fixedly connected to the bottom of the feed box 2. A motor 8 is installed on the top of the fixed plate 5. A cam 10 is fixedly connected to the output end of the motor 8. A movable rod 7 is slidably connected inside the feed box 2. A fixed plate 9 is fixedly connected to the front end of the movable rod 7. A U-shaped plate 19 is fixedly connected to the other end of the movable rod 7. A spring 11 is sleeved on the surface of the movable rod 7, and one end of the spring 11 is connected to the movable rod 7. The rear fixing block is fixedly connected, the other end of the spring 11 is fixedly connected to the inner wall of the feed box 2, the inside of the feed box 2 is fixedly connected to the inclined plate 17, the inside of the feed box 2 is fixedly connected to the support plate 13, the top of the support plate 13 is slidably connected to the U-shaped plate 19, the inner wall of the rear side of the feed port is fixedly connected to the fixing plate 15, and several stone crushing cones 16 are fixedly connected to the opposite side of the fixing plate 15 and the U-shaped plate 19. A dust suction mechanism 3 is provided on the left side of the feed box 2, and several horizontal plates 14 are fixedly connected to the inside of the feed box 2.

[0017] The dust collection mechanism 3 includes a collection box 31. An air pump 32 is connected to the right side of the collection box 31, and a dust collection pipe 33 is connected to the top of the collection box 31. The other end of the dust collection pipe 33 is connected to the inside of the feed box 2. With the dust collection mechanism 3, when crushing stone, the air pump 32 can be turned on to generate negative pressure inside the collection box 31. The dust collected by the dust collection pipe 33 is then absorbed to reduce the dust from flying.

[0018] The collection box 31 is equipped with a collection container 6 inside, and the surface of the collection container 6 is equipped with a handle. By activating the suction pump 32 through the collection container 6, a negative pressure is generated inside the collection box 31. The collection box 31 is equipped with a filter screen, so that dust falls into the collection container 6 through the suction pipe 33, so as to collect the dust and gravel adsorbed by the suction pipe 33, which facilitates regular cleaning and maintenance of the collection box 31 and ensures its normal operation.

[0019] Slider 18 is fixedly connected to the left and right sides of the top of the U-shaped plate 19. The bottom of the inclined plate 17 is provided with a sliding groove that works with the slider 18. The slider 18 makes the forward and backward movement of the U-shaped plate 19 more stable.

[0020] The stone crushing cones 16 on one side of the fixed plate 15 and the stone crushing cones 16 on one side of the U-shaped plate 19 are staggered. The stone crushing cones 16 can be used to better crush the stone.

[0021] The top of the feed box 2 is hinged with a dust cover 4, and the top of the dust cover 4 is fixedly connected with a handle 12. With the dust cover 4 and the handle 12, it is easy for the staff to pull the handle 12 to close the dust cover 4, thereby blocking the dust.

[0022] Working principle: Before ball milling the crushed stone, the operator opens the dust cover 4, which is hinged to the feed box 2, through the handle 12 on the top of the dust cover 4, and pours the crushed stone into the feed box 2 from the feed inlet. Then, the horizontal plate 14 will screen the crushed stone, with larger crushed stone located on the surface of the horizontal plate 14. Next, the motor 8 is started, and the cam 10 at its output end rotates accordingly. Due to the eccentric structure of the cam 10, it will periodically push the fixed plate 9. The fixed plate 9 drives the movable rod 7 to move, and the movable rod 7 drives the U-shaped plate 19. The movement causes the crushing cone 16 on the rear side of the U-shaped plate 19 to crush the gravel. At this time, the spring 11 on the surface of the movable rod 7 is stretched. When the cam 10 rotates to disengage, the spring 11 is reset by its own elastic force, pulling the movable rod 7 backward to leave enough distance to impact the gravel again. At the same time, the suction pump 32 is activated, which creates negative pressure inside the collection box 31. The dust and fine particles rolled up are adsorbed through the dust suction pipe 33 to reduce dust flying.
