Technical Field
[0001] This utility model relates to the field of iron ore processing technology, specifically to a fine iron ore grinding mill. Background Technology
[0002] In the iron ore mining and processing process, after the raw ore is crushed, it needs to be ground. Grinding uses the impact and abrasion of the media and the ore itself to further reduce the particle size of the ore until it is ground into powder. The purpose is to maximize the liberation of the useful minerals and gangue minerals that make up the ore, so as to provide materials with particle size that meet the requirements of the next beneficiation process.
[0003] Iron ore refining mills are needed in the iron ore processing. A patent document with publication number CN221413282U discloses an iron ore refining mill, including a shell. A fixed frame is fixedly installed at the bottom of the shell, and fixed plates are fixedly installed on both the left and right sides of the inner side of the fixed frame. A collection box is movably connected to the inner side of the fixed plates. This invention utilizes a collection box, a lifting plate, a spring, a rotating shaft, and an elliptical plate. When the operator starts the first motor, the rotation of the first motor causes the rotating shaft to rotate, carrying the elliptical plate. At this time, the elliptical plate rotates and squeezes the collection box, which moves smoothly upward under the limiting cooperation of the lifting plate and the fixed plate.
[0004] However, when the present invention's iron ore fine processing grinding mill encounters two or more pieces of ore during grinding, they will accumulate at the origin and form irregular shapes such as intersections, which can easily cause blockages, resulting in uneven grinding and low efficiency, and cannot meet production needs. Therefore, an iron ore fine processing grinding mill is proposed to solve the problems mentioned above. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a fine iron ore grinding mill with advantages such as high grinding efficiency and strong practicality. It solves the problem that existing fine iron ore grinding mills tend to accumulate at the origin when two or more pieces of ore are involved in grinding, forming irregular shapes such as intersections, which can easily cause blockages, resulting in uneven grinding, low efficiency, and failure to meet production needs.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fine iron ore grinding mill, comprising a housing, a feed hopper fixedly connected to the outside of the housing, a controller fixedly installed on the outside of the housing, and two guide plates fixedly connected to the inner wall of the housing. The housing is provided with a grinding mechanism inside, and the upper surface of the housing is provided with an extrusion mechanism extending into its interior.
[0007] The grinding mechanism includes two grinding rollers rotatably mounted inside the housing and located at the bottom of the guide plate, a transmission wheel fixedly mounted at one end of the two grinding rollers, and a synchronous belt drivingly connected between the two transmission wheels;
[0008] The extrusion mechanism includes two mounting brackets fixedly connected to the top of the housing, a geared motor fixedly installed outside the mounting bracket on the right side, a rocker arm fixedly connected to the output shaft of the geared motor, a connecting lug rotatably connected to the outside of the rocker arm, a mounting cylinder hinged to the bottom of the connecting lug, and an extrusion block disposed at the bottom of the mounting cylinder.
[0009] Furthermore, a drive motor is fixedly installed on the back of the housing, and the output shaft of the drive motor is fixedly connected to one end of one of the grinding rollers. The drive motor is electrically connected to the controller.
[0010] Furthermore, the rocker arm is rotatably connected to the interior of the two mounting brackets, the connecting ear is oscillatingly connected to the interior of the housing, and the interior of the housing has an opening adapted to the connecting ear.
[0011] Furthermore, the extrusion block is an inverted triangle and is adapted to the inclination of the two guide plates, and the outer diameter of the extrusion block is adapted to the inner diameter of the box.
[0012] Furthermore, an electric push rod is fixedly installed on the inner top wall of the mounting cylinder, and an extension rod extending to the outside of the mounting cylinder is fixedly connected to the output end of the electric push rod, and the extrusion block is fixedly connected to the bottom end of the extension rod.
[0013] Furthermore, the mounting cylinder is a hollow cylinder, and the interior of the mounting cylinder has a movable opening adapted to the extension rod.

[0015] Compared with the prior art, this utility model provides a fine iron ore grinding mill, which has the following beneficial effects:
[0016] 1. This iron ore fine processing grinding mill uses a controller to start a reduction motor that drives a rocker arm to rotate. The rocker arm moves the connecting lugs and mounting cylinder up and down, causing the extrusion block to reciprocate under gravity. Then, the drive motor is started, and its output shaft drives the transmission wheel and synchronous belt to rotate relative to each other. This allows the ore to be more evenly extruded and ground inside the mill, thereby improving grinding efficiency and grinding effect, achieving the advantage of high grinding efficiency.
[0017] 2. This iron ore fine processing grinding mill uses a controller to activate an electric push rod that extends and retracts, causing the extension rod to move downwards. This allows the extrusion block to move downwards and contact the guide plate. By adjusting the distance between the extrusion block and the guide plate, fine grinding of ores of different sizes can be achieved, improving product quality and demonstrating strong practicality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0024] Please see Figures 1 to 4 This embodiment of an iron ore fine processing grinding mill includes a housing 1, a feed hopper 2 fixedly connected to the outside of the housing 1, a controller 3 fixedly installed on the outside of the housing 1, and two guide plates 4 fixedly connected to the inner wall of the housing 1. A grinding mechanism is provided inside the housing 1, and an extrusion mechanism extending into the upper surface of the housing 1 is provided. The grinding mechanism includes two grinding rollers 5 rotatably installed inside the housing 1 and located at the bottom of the guide plates 4, a transmission wheel 6 fixedly installed at one end of the two grinding rollers 5, and a synchronous belt 7 drivingly connected between the two transmission wheels 6.
[0025] A drive motor is fixedly mounted on the back of the housing 1. The output shaft of the drive motor is fixedly connected to one end of one of the grinding rollers 5. The drive motor is electrically connected to the controller 3. The controller 3 starts the drive motor, causing its output shaft to drive the transmission wheel 6 and the synchronous belt 7 to rotate relative to each other.
[0026] It should be noted that the bottom of the box 1 has a discharge port, and the bottom of the box 1 is connected to four support legs.
[0027] In this embodiment, the extrusion mechanism includes two mounting brackets 8 fixedly connected to the top of the housing 1, a geared motor 9 fixedly installed outside the right mounting bracket 8, a rocker arm 10 fixedly connected to the output shaft of the geared motor 9, a connecting lug 11 rotatably connected to the outside of the rocker arm 10, a mounting cylinder 12 hinged to the bottom of the connecting lug 11, and an extrusion block 13 disposed at the bottom of the mounting cylinder 12. The controller 3 starts the geared motor 9 to rotate the rocker arm 10, causing the rocker arm 10 to move the connecting lug 11 and the mounting cylinder 12 up and down. This allows the extrusion block 13 to reciprocate under gravity, extruding and grinding the ore more evenly inside the housing 1, thereby improving grinding efficiency and grinding effect.
[0028] The rocker arm 10 is rotatably connected to the inside of the two mounting brackets 8, and the connecting ear 11 is swayably connected to the inside of the housing 1. The inside of the housing 1 has an opening that is compatible with the connecting ear 11.
[0029] Specifically, the extrusion block 13 is an inverted triangle and is adapted to the inclination of the two guide plates 4. The outer diameter of the extrusion block 13 is adapted to the inner diameter of the box 1.
[0030] It should be noted that an electric push rod 14 is fixedly installed on the inner top wall of the mounting cylinder 12. An extension rod 15 extending to the outside of the mounting cylinder 12 is fixedly connected to the output end of the electric push rod 14. The extrusion block 13 is fixedly connected to the bottom end of the extension rod 15. The mounting cylinder 12 is a hollow cylinder, and a movable opening adapted to the extension rod 15 is opened inside the mounting cylinder 12. The controller 3 starts the electric push rod 14 to extend and retract, driving the extension rod 15 to move downward, so that the extrusion block 13 moves downward and contacts the guide plate 4. By adjusting the distance between the extrusion block 13 and the guide plate 4, fine grinding of ores of different sizes can be achieved, improving product quality and achieving the advantage of strong practicality.
[0031] The working principle of the above embodiments is as follows:
[0032] In use, iron ore is fed into the housing 1 through the feed hopper 2. The drive motor is started by the controller 3, which drives the transmission wheel 6 and the synchronous belt 7 to rotate relative to each other. The geared motor 9 is started by the controller 3 to drive the rocker arm 10 to rotate. The rocker arm 10 drives the connecting ear 11 and the mounting cylinder 12 to move up and down, so that the extrusion block 13 is extruded up and down under the action of gravity, so that the ore is subjected to more uniform extrusion and grinding inside the housing 1. The electric push rod 14 is started by the controller 3 to extend and retract, which drives the extension rod 15 to move downward, so that the extrusion block 13 moves downward and contacts the guide plate 4. By adjusting the distance between the extrusion block 13 and the guide plate 4, fine grinding of ores of different sizes can be achieved.
