Description

Technical Field

[0001] This utility model belongs to the technical field of ultrafine heavy calcium carbonate powder processing equipment, and particularly relates to a noise-proof ultrafine heavy calcium carbonate pulverizing device. Background Technology

[0002] The ball mill for processing ultrafine heavy calcium carbonate powder is an ultrafine grinding equipment specifically designed for the characteristics of heavy calcium carbonate (made by grinding calcite, limestone, etc.). Its core function is to further process the coarsely crushed calcium carbonate raw material into ultrafine powder at the micron level (usually up to d97≤10μm, and some can meet even finer requirements).

[0003] Because the balls inside the ball mill change position significantly during rolling, the resulting impact force is quite strong, generating a lot of noise during operation. This leads to the problem of high noise levels in conventional ultrafine heavy calcium carbonate powder processing equipment.

[0004] To address this issue, we propose a noise-reducing ultrafine heavy calcium carbonate pulverizing device. Utility Model Content

[0005] The purpose of this invention is to solve the problem of excessive noise in conventional ultrafine heavy calcium carbonate powder processing equipment, and to propose a noise-proof ultrafine heavy calcium carbonate pulverizing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A noise-reducing ultrafine heavy calcium carbonate pulverizing device includes a motor, a frame fixedly connected to the outside of the motor, a guide wheel rotatably mounted on the upper part of the frame, a roller rollingly supported on the guide wheel, a baffle fixedly connected to the inlet of the roller, a grinding disc movably arranged inside the roller, the lower end of the grinding disc rollingly contacting the inner wall of the roller, a sieve fixedly connected to the lower part of the roller, a retaining ring fixedly connected to the outside of the roller and the sieve, a guide shell covering the outside of the sieve, a fixed seat fixedly connected to the lower end of the guide shell, the lower end of the fixed seat fixedly connected to the frame, a gear ring fixedly connected to the side of the roller, a gear fixedly connected to the output shaft of the motor, the gear meshing with the gear ring, and a feeding hopper fixedly connected to the upper end of the frame. Material is placed into the hopper and fed into the drum. An external power source drives a motor to rotate a gear, which in turn rotates a gear ring, causing the drum to rotate. This causes the crushing discs to roll and crush the material inside the drum. The movable design of each crushing disc ensures that the lower end of each disc is compacted against the inner wall of the drum, preventing air compression, reducing impact noise, and improving practicality.

[0007] Preferably, the roller includes a cylinder body, the toothed ring is fixedly mounted on the cylinder body, and a guide nozzle is fixedly connected to the side of the cylinder body. The guide nozzle guides the material into the cylinder body.

[0008] Preferably, the sieve includes an outer shell, with a screen fixedly connected inside the outer shell. The upper end of the outer shell is fixedly connected to the lower end of the cylinder, and the outer shell and the internal space of the cylinder are connected. When the material passes through the opening of the cylinder and comes into contact with the screen, the qualified fine powder is sieved out by the screen and guided into the feed guide shell through the outer shell, facilitating the discharge of qualified powder.

[0009] Preferably, the guide shell includes an annular shell, the lower part of which is fixedly connected to a discharge nozzle. The annular shell is fitted over the outer shell, but the annular shell does not contact the outer shell. Material discharged from the outer shell falls into the annular shell and is discharged outward through the discharge nozzle.

[0010] Preferably, the fixed base includes a base body, the upper end of which is fixedly connected to a fixed plate, the annular shell and the discharge nozzle are fixedly connected to the fixed plate, and the lower end of the base body is fixedly connected to the frame.

[0011] Preferably, the baffle includes a frame body, the outer end of which is fixedly connected to the opening of the cylinder. The frame body blocks the side of the compaction disc, maintaining the upright posture of the outermost compaction disc. A feed inlet is provided on the side of the frame body. Material in the guide nozzle enters the main cylinder through the feed inlet.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. The material is placed into the feeding hopper and fed into the drum. An external power source drives the motor to rotate the gears, which in turn rotate the gear ring, causing the drum to rotate. This causes the crushing discs to roll and crush the material inside the drum. The movable design of each crushing disc ensures that the lower end of each disc is compacted against the inner wall of the drum, preventing air compression, reducing impact noise, and improving practicality.

[0013] 2. When the material passes through the opening of the cylinder and comes into contact with the screen, the qualified fine powder is screened out by the screen and then guided into the feed guide shell through the outer shell, so that the qualified powder can be discharged easily.

The material in the guide nozzle 22 enters the main cylinder 21 through the feed inlet 62.

[0023] Working principle: The material is put into the feeding hopper 8 and fed into the roller 2.
