Description

Technical Field

[0001] The utility model relates to the technical field of ore mills, in particular to a feeding device for an ore mill. Background Art

[0002] Ore grinding is a process in which the particle size of the ore is further reduced in mechanical equipment by means of the impact and grinding of the medium (steel balls, steel rods, gravel) and the ore itself, thereby forming smaller particles. The ore enters the mill through the feed port, and after being ground by the mill, the particle size of the ore becomes smaller, and finally it is discharged through the discharge pipe. When the ore is ground inside the mill, some ore particles will have cracks on the surface after grinding, but from the appearance, these ore particles are still a complete individual. The size of such ore particles does not meet the subsequent processing requirements. Therefore, these ore particles are often regarded as unsuccessfully ground ores when sieving, and need to be recycled and repeated for grinding. However, such ore particles can be easily broken into the required ore particles under the action of certain external forces. If such ore particles are recycled and re-grinded just because they fail to pass the screening, it will not only reduce the efficiency of ore grinding, but also increase the operating cost of ore grinding equipment. Utility Model Content

[0003] The purpose of the utility model is to avoid the deficiencies of the prior art and provide an ore mill unloading device, thereby effectively solving the deficiencies in the prior art.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a feeding device for an ore mill, comprising a mill body, wherein a feed pipe is provided at one end of the feed port of the mill body, and a feeding pipe is provided at one end of the discharge port of the mill body, and a feeding hopper is provided at the end of the feeding pipe, and a plurality of synchronously rotatable pounding rollers are arranged side by side in the feeding hopper, a feeding gap is provided between each of the pounding rollers, and a plurality of pounding rods are evenly distributed on the surface of the pounding rollers, and the pounding rods on adjacent pounding rollers are staggered with each other.

[0005] Furthermore, the crushing roller is evenly provided with crushing thorns at positions corresponding to the pounding rods.

[0006] Furthermore, a transmission gear is provided at one end of each of the crushing rollers, and the transmission gears are meshed with each other, and one of the crushing rollers is controlled to rotate by a driving mechanism.

[0007] Furthermore, the driving mechanism is a motor, and the driving shaft of the motor is connected to the rotating shaft of any one of the pounding rollers.

[0008] Furthermore, the motor is arranged on a side outside the lower hopper, a mounting plate is arranged on the side wall of the lower hopper, and the motor is fixed on the mounting plate.

[0009] Furthermore, one end of the discharge hopper connected to the discharge pipe is provided with a first flange, and the two are fixedly connected via the first flange.

[0010] Furthermore, a feeding hopper is provided at the end of the feeding pipe.

[0011] Furthermore, one end of the feed pipe connected to the feed hopper is provided with a second flange, and the two are fixedly connected via the second flange.

[0012] The above-mentioned technical scheme of the utility model has the following beneficial effects: the utility model arranges a plurality of pounding rollers at the lower hopper and arranges pounding rods on the pounding rollers. After the ore is ground by the mill, it will fall at the pounding rollers. The rotating pounding rollers and the pounding rods thereon will hit the fallen ore particles. At this time, under the action of external force, some ores that are large in volume but have cracks will break apart, thereby meeting subsequent processing needs, avoiding re-grinding due to the ore particles being too large, thereby reducing the generation of re-ground ore particles, which not only improves the grinding efficiency but also saves operating costs.

[0015] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figure 1-2As shown, an ore mill unloading device described in this embodiment includes a mill body 1, a feed pipe 2 is provided at one end of the feed port of the mill body 1, a unloading pipe 3 is provided at one end of the discharge port of the mill body 1, a unloading hopper 4 is provided at the end of the unloading pipe 3, a plurality of synchronously rotatable pounding rollers 5 are arranged side by side in the unloading hopper 4, a unloading gap is provided between each pounding roller 5, a plurality of pounding rods 6 are evenly distributed on the surface of the pounding roller 5, the pounding rods 6 on adjacent pounding rollers 5 are staggered with each other, and the pounding rods 6 are staggered with each other, so that the pounding rods 6 can cooperate with each other to perform the pounding work.

[0018] Crushing thorns 7 are evenly distributed on the crushing roller 5 between the corresponding pounding rods 6. The crushing thorns 7 improve the crushing capacity of the crushing roller 5. After the ground ore particles fall onto the crushing thorns 7, they can also assist in crushing, thereby improving the overall crushing capacity of the mill.

[0019] A transmission gear 8 is provided at one end of each shredder roller 5 , and the transmission gears 8 are meshed with each other. One of the shredder rollers 5 is controlled to rotate by a driving mechanism 9 .

[0020] The driving mechanism 9 is a motor, and the driving shaft of the motor is connected to the rotating shaft of any one of the tamping rollers 5 .

[0021] Preferably, three groups of crushing rollers 5 are arranged side by side, and the motor is connected to the crushing rollers 5 in the middle.

[0022] The motor is arranged on one side outside the lower hopper 4 . A mounting plate 10 is arranged on the side wall of the lower hopper 4 , and the motor is fixed on the mounting plate 10 .

[0023] A first flange 11 is disposed at one end of the discharge hopper 4 and the discharge pipe 3 , and the two are fixedly connected via the first flange 11 .

[0024] A feeding hopper 12 is provided at the end of the feeding pipe 2 .

[0025] A second flange 13 is disposed at one end of the feed pipe 2 and the feed hopper 12 , and the two are fixedly connected via the second flange 13 .

[0026] The working principle of the utility model is as follows: the ore enters the feed pipe 2 through the feed hopper 12, and then enters the mill body 1 through the feed pipe 2 for grinding. After the grinding is completed, the ore particles are discharged through the discharge pipe 3. When the ore particles are discharged, they will first pass through the pounding roller 5 in the lower hopper 4. The motor starts a pounding roller 5 to rotate, and the other pounding rollers 5 rotate together under the cooperative drive of the transmission gear 8. When the ore particles fall, the pounding rod 6 and the crushing thorns 7 on the pounding roller 5 cooperate with each other to hit and collide the falling ore particles. In this way, under the action of external force, the ore particles with cracks will crack, thereby avoiding the ore particles being too large to be screened, reducing the generation of large-particle ore, and then reducing the workload of re-grinding the ore particles, and also avoiding the blockage of the lower hopper 4.

[0027] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
